If any of the promises are rejected the + * {@link ngRoute.$route#$routeChangeError $routeChangeError} event is fired. + * For easier access to the resolved dependencies from the template, the `resolve` map will + * be available on the scope of the route, under `$resolve` (by default) or a custom name + * specified by the `resolveAs` property (see below). This can be particularly useful, when + * working with {@link angular.Module#component components} as route templates.
+ *
+ * **Note:** If your scope already contains a property with this name, it will be hidden + * or overwritten. Make sure, you specify an appropriate name for this property, that + * does not collide with other properties on the scope. + *
+ * The map object is: + * + * - `key` – `{string}`: a name of a dependency to be injected into the controller. + * - `factory` - `{string|Function}`: If `string` then it is an alias for a service. + * Otherwise if function, then it is {@link auto.$injector#invoke injected} + * and the return value is treated as the dependency. If the result is a promise, it is + * resolved before its value is injected into the controller. Be aware that + * `ngRoute.$routeParams` will still refer to the previous route within these resolve + * functions. Use `$route.current.params` to access the new route parameters, instead. + * + * - `resolveAs` - `{string=}` - The name under which the `resolve` map will be available on + * the scope of the route. If omitted, defaults to `$resolve`. + * + * - `redirectTo` – `{(string|Function)=}` – value to update + * {@link ng.$location $location} path with and trigger route redirection. + * + * If `redirectTo` is a function, it will be called with the following parameters: + * + * - `{Object.}` - route parameters extracted from the current + * `$location.path()` by applying the current route templateUrl. + * - `{string}` - current `$location.path()` + * - `{Object}` - current `$location.search()` + * + * The custom `redirectTo` function is expected to return a string which will be used + * to update `$location.url()`. If the function throws an error, no further processing will + * take place and the {@link ngRoute.$route#$routeChangeError $routeChangeError} event will + * be fired. + * + * Routes that specify `redirectTo` will not have their controllers, template functions + * or resolves called, the `$location` will be changed to the redirect url and route + * processing will stop. The exception to this is if the `redirectTo` is a function that + * returns `undefined`. In this case the route transition occurs as though there was no + * redirection. + * + * - `resolveRedirectTo` – `{Function=}` – a function that will (eventually) return the value + * to update {@link ng.$location $location} URL with and trigger route redirection. In + * contrast to `redirectTo`, dependencies can be injected into `resolveRedirectTo` and the + * return value can be either a string or a promise that will be resolved to a string. + * + * Similar to `redirectTo`, if the return value is `undefined` (or a promise that gets + * resolved to `undefined`), no redirection takes place and the route transition occurs as + * though there was no redirection. + * + * If the function throws an error or the returned promise gets rejected, no further + * processing will take place and the + * {@link ngRoute.$route#$routeChangeError $routeChangeError} event will be fired. + * + * `redirectTo` takes precedence over `resolveRedirectTo`, so specifying both on the same + * route definition, will cause the latter to be ignored. + * + * - `[reloadOnUrl=true]` - `{boolean=}` - reload route when any part of the URL changes + * (including the path) even if the new URL maps to the same route. + * + * If the option is set to `false` and the URL in the browser changes, but the new URL maps + * to the same route, then a `$routeUpdate` event is broadcasted on the root scope (without + * reloading the route). + * + * - `[reloadOnSearch=true]` - `{boolean=}` - reload route when only `$location.search()` + * or `$location.hash()` changes. + * + * If the option is set to `false` and the URL in the browser changes, then a `$routeUpdate` + * event is broadcasted on the root scope (without reloading the route). + * + *

+ * + * Therefore the above can be simplified as: + * + * ```js + * var myModule = angular.module(...); + * + * myModule.directive('directiveName', function factory(injectables) { + * var directiveDefinitionObject = { + * link: function postLink(scope, iElement, iAttrs) { ... } + * }; + * return directiveDefinitionObject; + * // or + * // return function postLink(scope, iElement, iAttrs) { ... } + * }); + * ``` + * + * ### Life-cycle hooks + * Directive controllers can provide the following methods that are called by AngularJS at points in the life-cycle of the + * directive: + * * `$onInit()` - Called on each controller after all the controllers on an element have been constructed and + * had their bindings initialized (and before the pre & post linking functions for the directives on + * this element). This is a good place to put initialization code for your controller. + * * `$onChanges(changesObj)` - Called whenever one-way (`<`) or interpolation (`@`) bindings are updated. The + * `changesObj` is a hash whose keys are the names of the bound properties that have changed, and the values are an + * object of the form `{ currentValue, previousValue, isFirstChange() }`. Use this hook to trigger updates within a + * component such as cloning the bound value to prevent accidental mutation of the outer value. Note that this will + * also be called when your bindings are initialized. + * * `$doCheck()` - Called on each turn of the digest cycle. Provides an opportunity to detect and act on + * changes. Any actions that you wish to take in response to the changes that you detect must be + * invoked from this hook; implementing this has no effect on when `$onChanges` is called. For example, this hook + * could be useful if you wish to perform a deep equality check, or to check a Date object, changes to which would not + * be detected by AngularJS's change detector and thus not trigger `$onChanges`. This hook is invoked with no arguments; + * if detecting changes, you must store the previous value(s) for comparison to the current values. + * * `$onDestroy()` - Called on a controller when its containing scope is destroyed. Use this hook for releasing + * external resources, watches and event handlers. Note that components have their `$onDestroy()` hooks called in + * the same order as the `$scope.$broadcast` events are triggered, which is top down. This means that parent + * components will have their `$onDestroy()` hook called before child components. + * * `$postLink()` - Called after this controller's element and its children have been linked. Similar to the post-link + * function this hook can be used to set up DOM event handlers and do direct DOM manipulation. + * Note that child elements that contain `templateUrl` directives will not have been compiled and linked since + * they are waiting for their template to load asynchronously and their own compilation and linking has been + * suspended until that occurs. + * + * #### Comparison with life-cycle hooks in the new Angular + * The new Angular also uses life-cycle hooks for its components. While the AngularJS life-cycle hooks are similar there are + * some differences that you should be aware of, especially when it comes to moving your code from AngularJS to Angular: + * + * * AngularJS hooks are prefixed with `$`, such as `$onInit`. Angular hooks are prefixed with `ng`, such as `ngOnInit`. + * * AngularJS hooks can be defined on the controller prototype or added to the controller inside its constructor. + * In Angular you can only define hooks on the prototype of the Component class. + * * Due to the differences in change-detection, you may get many more calls to `$doCheck` in AngularJS than you would to + * `ngDoCheck` in Angular. + * * Changes to the model inside `$doCheck` will trigger new turns of the digest loop, which will cause the changes to be + * propagated throughout the application. + * Angular does not allow the `ngDoCheck` hook to trigger a change outside of the component. It will either throw an + * error or do nothing depending upon the state of `enableProdMode()`. + * + * #### Life-cycle hook examples + * + * This example shows how you can check for mutations to a Date object even though the identity of the object + * has not changed. + * + * + * + * angular.module('do-check-module', []) + * .component('app', { + * template: + * 'Month: ' + + * 'Date: {{ $ctrl.date }}' + + * '', + * controller: function() { + * this.date = new Date(); + * this.month = this.date.getMonth(); + * this.updateDate = function() { + * this.date.setMonth(this.month); + * }; + * } + * }) + * .component('test', { + * bindings: { date: '<' }, + * template: + * '
{{ $ctrl.log | json }}
', + * controller: function() { + * var previousValue; + * this.log = []; + * this.$doCheck = function() { + * var currentValue = this.date && this.date.valueOf(); + * if (previousValue !== currentValue) { + * this.log.push('doCheck: date mutated: ' + this.date); + * previousValue = currentValue; + * } + * }; + * } + * }); + * + * + * + * + * + * + * This example show how you might use `$doCheck` to trigger changes in your component's inputs even if the + * actual identity of the component doesn't change. (Be aware that cloning and deep equality checks on large + * arrays or objects can have a negative impact on your application performance.) + * + * + * + *
+ * + * + * 
{{ items }}
+ * + *
+ * + * + * angular.module('do-check-module', []) + * .component('test', { + * bindings: { items: '<' }, + * template: + * '
{{ $ctrl.log | json }}
', + * controller: function() { + * this.log = []; + * + * this.$doCheck = function() { + * if (this.items_ref !== this.items) { + * this.log.push('doCheck: items changed'); + * this.items_ref = this.items; + * } + * if (!angular.equals(this.items_clone, this.items)) { + * this.log.push('doCheck: items mutated'); + * this.items_clone = angular.copy(this.items); + * } + * }; + * } + * }); + * + * + * + * + * ### Directive Definition Object + * + * The directive definition object provides instructions to the {@link ng.$compile + * compiler}. The attributes are: + * + * #### `multiElement` + * When this property is set to true (default is `false`), the HTML compiler will collect DOM nodes between + * nodes with the attributes `directive-name-start` and `directive-name-end`, and group them + * together as the directive elements. It is recommended that this feature be used on directives + * which are not strictly behavioral (such as {@link ngClick}), and which + * do not manipulate or replace child nodes (such as {@link ngInclude}). + * + * #### `priority` + * When there are multiple directives defined on a single DOM element, sometimes it + * is necessary to specify the order in which the directives are applied. The `priority` is used + * to sort the directives before their `compile` functions get called. Priority is defined as a + * number. Directives with greater numerical `priority` are compiled first. Pre-link functions + * are also run in priority order, but post-link functions are run in reverse order. The order + * of directives with the same priority is undefined. The default priority is `0`. + * + * #### `terminal` + * If set to true then the current `priority` will be the last set of directives + * which will execute (any directives at the current priority will still execute + * as the order of execution on same `priority` is undefined). Note that expressions + * and other directives used in the directive's template will also be excluded from execution. + * + * #### `scope` + * The scope property can be `false`, `true`, or an object: + * + * * **`false` (default):** No scope will be created for the directive. The directive will use its + * parent's scope. + * + * * **`true`:** A new child scope that prototypically inherits from its parent will be created for + * the directive's element. If multiple directives on the same element request a new scope, + * only one new scope is created. + * + * * **`{...}` (an object hash):** A new "isolate" scope is created for the directive's template. + * The 'isolate' scope differs from normal scope in that it does not prototypically + * inherit from its parent scope. This is useful when creating reusable components, which should not + * accidentally read or modify data in the parent scope. Note that an isolate scope + * directive without a `template` or `templateUrl` will not apply the isolate scope + * to its children elements. + * + * The 'isolate' scope object hash defines a set of local scope properties derived from attributes on the + * directive's element. These local properties are useful for aliasing values for templates. The keys in + * the object hash map to the name of the property on the isolate scope; the values define how the property + * is bound to the parent scope, via matching attributes on the directive's element: + * + * * `@` or `@attr` - bind a local scope property to the value of DOM attribute. The result is + * always a string since DOM attributes are strings. If no `attr` name is specified then the + * attribute name is assumed to be the same as the local name. Given `` and the isolate scope definition `scope: { localName:'@myAttr' }`, + * the directive's scope property `localName` will reflect the interpolated value of `hello + * {{name}}`. As the `name` attribute changes so will the `localName` property on the directive's + * scope. The `name` is read from the parent scope (not the directive's scope). + * + * * `=` or `=attr` - set up a bidirectional binding between a local scope property and an expression + * passed via the attribute `attr`. The expression is evaluated in the context of the parent scope. + * If no `attr` name is specified then the attribute name is assumed to be the same as the local + * name. Given `` and the isolate scope definition `scope: { + * localModel: '=myAttr' }`, the property `localModel` on the directive's scope will reflect the + * value of `parentModel` on the parent scope. Changes to `parentModel` will be reflected in + * `localModel` and vice versa. If the binding expression is non-assignable, or if the attribute + * isn't optional and doesn't exist, an exception + * ({@link error/$compile/nonassign `$compile:nonassign`}) will be thrown upon discovering changes + * to the local value, since it will be impossible to sync them back to the parent scope. + * + * By default, the {@link ng.$rootScope.Scope#$watch `$watch`} + * method is used for tracking changes, and the equality check is based on object identity. + * However, if an object literal or an array literal is passed as the binding expression, the + * equality check is done by value (using the {@link angular.equals} function). It's also possible + * to watch the evaluated value shallowly with {@link ng.$rootScope.Scope#$watchCollection + * `$watchCollection`}: use `=*` or `=*attr` + * + * * `<` or `` and directive definition of + * `scope: { localModel:'` and the isolate scope definition `scope: { + * localFn:'&myAttr' }`, the isolate scope property `localFn` will point to a function wrapper for + * the `count = count + value` expression. Often it's desirable to pass data from the isolated scope + * via an expression to the parent scope. This can be done by passing a map of local variable names + * and values into the expression wrapper fn. For example, if the expression is `increment(amount)` + * then we can specify the amount value by calling the `localFn` as `localFn({amount: 22})`. + * + * All 4 kinds of bindings (`@`, `=`, `<`, and `&`) can be made optional by adding `?` to the expression. + * The marker must come after the mode and before the attribute name. + * See the {@link error/$compile/iscp Invalid Isolate Scope Definition error} for definition examples. + * This is useful to refine the interface directives provide. + * One subtle difference between optional and non-optional happens **when the binding attribute is not + * set**: + * - the binding is optional: the property will not be defined + * - the binding is not optional: the property is defined + * + * ```js + *app.directive('testDir', function() { + return { + scope: { + notoptional: '=', + optional: '=?', + }, + bindToController: true, + controller: function() { + this.$onInit = function() { + console.log(this.hasOwnProperty('notoptional')) // true + console.log(this.hasOwnProperty('optional')) // false + } + } + } + }) + *``` + * + * + * ##### Combining directives with different scope defintions + * + * In general it's possible to apply more than one directive to one element, but there might be limitations + * depending on the type of scope required by the directives. The following points will help explain these limitations. + * For simplicity only two directives are taken into account, but it is also applicable for several directives: + * + * * **no scope** + **no scope** => Two directives which don't require their own scope will use their parent's scope + * * **child scope** + **no scope** => Both directives will share one single child scope + * * **child scope** + **child scope** => Both directives will share one single child scope + * * **isolated scope** + **no scope** => The isolated directive will use it's own created isolated scope. The other directive will use + * its parent's scope + * * **isolated scope** + **child scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives cannot + * be applied to the same element. + * * **isolated scope** + **isolated scope** => **Won't work!** Only one scope can be related to one element. Therefore these directives + * cannot be applied to the same element. + * + * + * #### `bindToController` + * This property is used to bind scope properties directly to the controller. It can be either + * `true` or an object hash with the same format as the `scope` property. + * + * When an isolate scope is used for a directive (see above), `bindToController: true` will + * allow a component to have its properties bound to the controller, rather than to scope. + * + * After the controller is instantiated, the initial values of the isolate scope bindings will be bound to the controller + * properties. You can access these bindings once they have been initialized by providing a controller method called + * `$onInit`, which is called after all the controllers on an element have been constructed and had their bindings + * initialized. + * + * It is also possible to set `bindToController` to an object hash with the same format as the `scope` property. + * This will set up the scope bindings to the controller directly. Note that `scope` can still be used + * to define which kind of scope is created. By default, no scope is created. Use `scope: {}` to create an isolate + * scope (useful for component directives). + * + * If both `bindToController` and `scope` are defined and have object hashes, `bindToController` overrides `scope`. + * + * + * #### `controller` + * Controller constructor function. The controller is instantiated before the + * pre-linking phase and can be accessed by other directives (see + * `require` attribute). This allows the directives to communicate with each other and augment + * each other's behavior. The controller is injectable (and supports bracket notation) with the following locals: + * + * * `$scope` - Current scope associated with the element + * * `$element` - Current element + * * `$attrs` - Current attributes object for the element + * * `$transclude` - A transclude linking function pre-bound to the correct transclusion scope: + * `function([scope], cloneLinkingFn, futureParentElement, slotName)`: + * * `scope`: (optional) override the scope. + * * `cloneLinkingFn`: (optional) argument to create clones of the original transcluded content. + * * `futureParentElement` (optional): + * * defines the parent to which the `cloneLinkingFn` will add the cloned elements. + * * default: `$element.parent()` resp. `$element` for `transclude:'element'` resp. `transclude:true`. + * * only needed for transcludes that are allowed to contain non html elements (e.g. SVG elements) + * and when the `cloneLinkingFn` is passed, + * as those elements need to created and cloned in a special way when they are defined outside their + * usual containers (e.g. like ``). + * * See also the `directive.templateNamespace` property. + * * `slotName`: (optional) the name of the slot to transclude. If falsy (e.g. `null`, `undefined` or `''`) + * then the default transclusion is provided. + * The `$transclude` function also has a method on it, `$transclude.isSlotFilled(slotName)`, which returns + * `true` if the specified slot contains content (i.e. one or more DOM nodes). + * + * #### `require` + * Require another directive and inject its controller as the fourth argument to the linking function. The + * `require` property can be a string, an array or an object: + * * a **string** containing the name of the directive to pass to the linking function + * * an **array** containing the names of directives to pass to the linking function. The argument passed to the + * linking function will be an array of controllers in the same order as the names in the `require` property + * * an **object** whose property values are the names of the directives to pass to the linking function. The argument + * passed to the linking function will also be an object with matching keys, whose values will hold the corresponding + * controllers. + * + * If the `require` property is an object and `bindToController` is truthy, then the required controllers are + * bound to the controller using the keys of the `require` property. This binding occurs after all the controllers + * have been constructed but before `$onInit` is called. + * If the name of the required controller is the same as the local name (the key), the name can be + * omitted. For example, `{parentDir: '^^'}` is equivalent to `{parentDir: '^^parentDir'}`. + * See the {@link $compileProvider#component} helper for an example of how this can be used. + * If no such required directive(s) can be found, or if the directive does not have a controller, then an error is + * raised (unless no link function is specified and the required controllers are not being bound to the directive + * controller, in which case error checking is skipped). The name can be prefixed with: + * + * * (no prefix) - Locate the required controller on the current element. Throw an error if not found. + * * `?` - Attempt to locate the required controller or pass `null` to the `link` fn if not found. + * * `^` - Locate the required controller by searching the element and its parents. Throw an error if not found. + * * `^^` - Locate the required controller by searching the element's parents. Throw an error if not found. + * * `?^` - Attempt to locate the required controller by searching the element and its parents or pass + * `null` to the `link` fn if not found. + * * `?^^` - Attempt to locate the required controller by searching the element's parents, or pass + * `null` to the `link` fn if not found. + * + * + * #### `controllerAs` + * Identifier name for a reference to the controller in the directive's scope. + * This allows the controller to be referenced from the directive template. This is especially + * useful when a directive is used as component, i.e. with an `isolate` scope. It's also possible + * to use it in a directive without an `isolate` / `new` scope, but you need to be aware that the + * `controllerAs` reference might overwrite a property that already exists on the parent scope. + * + * + * #### `restrict` + * String of subset of `EACM` which restricts the directive to a specific directive + * declaration style. If omitted, the defaults (elements and attributes) are used. + * + * * `E` - Element name (default): `` + * * `A` - Attribute (default): `
` + * * `C` - Class: `
` + * * `M` - Comment: `` + * + * + * #### `templateNamespace` + * String representing the document type used by the markup in the template. + * AngularJS needs this information as those elements need to be created and cloned + * in a special way when they are defined outside their usual containers like `` and ``. + * + * * `html` - All root nodes in the template are HTML. Root nodes may also be + * top-level elements such as `` or ``. + * * `svg` - The root nodes in the template are SVG elements (excluding ``). + * * `math` - The root nodes in the template are MathML elements (excluding ``). + * + * If no `templateNamespace` is specified, then the namespace is considered to be `html`. + * + * #### `template` + * HTML markup that may: + * * Replace the contents of the directive's element (default). + * * Replace the directive's element itself (if `replace` is true - DEPRECATED). + * * Wrap the contents of the directive's element (if `transclude` is true). + * + * Value may be: + * + * * A string. For example `
{{delete_str}}
`. + * * A function which takes two arguments `tElement` and `tAttrs` (described in the `compile` + * function api below) and returns a string value. + * + * + * #### `templateUrl` + * This is similar to `template` but the template is loaded from the specified URL, asynchronously. + * + * Because template loading is asynchronous the compiler will suspend compilation of directives on that element + * for later when the template has been resolved. In the meantime it will continue to compile and link + * sibling and parent elements as though this element had not contained any directives. + * + * The compiler does not suspend the entire compilation to wait for templates to be loaded because this + * would result in the whole app "stalling" until all templates are loaded asynchronously - even in the + * case when only one deeply nested directive has `templateUrl`. + * + * Template loading is asynchronous even if the template has been preloaded into the {@link $templateCache}. + * + * You can specify `templateUrl` as a string representing the URL or as a function which takes two + * arguments `tElement` and `tAttrs` (described in the `compile` function api below) and returns + * a string value representing the url. In either case, the template URL is passed through {@link + * $sce#getTrustedResourceUrl $sce.getTrustedResourceUrl}. + * + * + * #### `replace` + *
+ * **Note:** `replace` is deprecated in AngularJS and has been removed in the new Angular (v2+). + *
+ * + * Specifies what the template should replace. Defaults to `false`. + * + * * `true` - the template will replace the directive's element. + * * `false` - the template will replace the contents of the directive's element. + * + * The replacement process migrates all of the attributes / classes from the old element to the new + * one. See the {@link guide/directive#template-expanding-directive + * Directives Guide} for an example. + * + * There are very few scenarios where element replacement is required for the application function, + * the main one being reusable custom components that are used within SVG contexts + * (because SVG doesn't work with custom elements in the DOM tree). + * + * #### `transclude` + * Extract the contents of the element where the directive appears and make it available to the directive. + * The contents are compiled and provided to the directive as a **transclusion function**. See the + * {@link $compile#transclusion Transclusion} section below. + * + * + * #### `compile` + * + * ```js + * function compile(tElement, tAttrs, transclude) { ... } + * ``` + * + * The compile function deals with transforming the template DOM. Since most directives do not do + * template transformation, it is not used often. The compile function takes the following arguments: + * + * * `tElement` - template element - The element where the directive has been declared. It is + * safe to do template transformation on the element and child elements only. + * + * * `tAttrs` - template attributes - Normalized list of attributes declared on this element shared + * between all directive compile functions. + * + * * `transclude` - [*DEPRECATED*!] A transclude linking function: `function(scope, cloneLinkingFn)` + * + *
+ * **Note:** The template instance and the link instance may be different objects if the template has + * been cloned. For this reason it is **not** safe to do anything other than DOM transformations that + * apply to all cloned DOM nodes within the compile function. Specifically, DOM listener registration + * should be done in a linking function rather than in a compile function. + *
+ + *
+ * **Note:** The compile function cannot handle directives that recursively use themselves in their + * own templates or compile functions. Compiling these directives results in an infinite loop and + * stack overflow errors. + * + * This can be avoided by manually using `$compile` in the postLink function to imperatively compile + * a directive's template instead of relying on automatic template compilation via `template` or + * `templateUrl` declaration or manual compilation inside the compile function. + *
+ * + *
+ * **Note:** The `transclude` function that is passed to the compile function is deprecated, as it + * e.g. does not know about the right outer scope. Please use the transclude function that is passed + * to the link function instead. + *
+ + * A compile function can have a return value which can be either a function or an object. + * + * * returning a (post-link) function - is equivalent to registering the linking function via the + * `link` property of the config object when the compile function is empty. + * + * * returning an object with function(s) registered via `pre` and `post` properties - allows you to + * control when a linking function should be called during the linking phase. See info about + * pre-linking and post-linking functions below. + * + * + * #### `link` + * This property is used only if the `compile` property is not defined. + * + * ```js + * function link(scope, iElement, iAttrs, controller, transcludeFn) { ... } + * ``` + * + * The link function is responsible for registering DOM listeners as well as updating the DOM. It is + * executed after the template has been cloned. This is where most of the directive logic will be + * put. + * + * * `scope` - {@link ng.$rootScope.Scope Scope} - The scope to be used by the + * directive for registering {@link ng.$rootScope.Scope#$watch watches}. + * + * * `iElement` - instance element - The element where the directive is to be used. It is safe to + * manipulate the children of the element only in `postLink` function since the children have + * already been linked. + * + * * `iAttrs` - instance attributes - Normalized list of attributes declared on this element shared + * between all directive linking functions. + * + * * `controller` - the directive's required controller instance(s) - Instances are shared + * among all directives, which allows the directives to use the controllers as a communication + * channel. The exact value depends on the directive's `require` property: + * * no controller(s) required: the directive's own controller, or `undefined` if it doesn't have one + * * `string`: the controller instance + * * `array`: array of controller instances + * + * If a required controller cannot be found, and it is optional, the instance is `null`, + * otherwise the {@link error:$compile:ctreq Missing Required Controller} error is thrown. + * + * Note that you can also require the directive's own controller - it will be made available like + * any other controller. + * + * * `transcludeFn` - A transclude linking function pre-bound to the correct transclusion scope. + * This is the same as the `$transclude` parameter of directive controllers, + * see {@link ng.$compile#-controller- the controller section for details}. + * `function([scope], cloneLinkingFn, futureParentElement)`. + * + * #### Pre-linking function + * + * Executed before the child elements are linked. Not safe to do DOM transformation since the + * compiler linking function will fail to locate the correct elements for linking. + * + * #### Post-linking function + * + * Executed after the child elements are linked. + * + * Note that child elements that contain `templateUrl` directives will not have been compiled + * and linked since they are waiting for their template to load asynchronously and their own + * compilation and linking has been suspended until that occurs. + * + * It is safe to do DOM transformation in the post-linking function on elements that are not waiting + * for their async templates to be resolved. + * + * + * ### Transclusion + * + * Transclusion is the process of extracting a collection of DOM elements from one part of the DOM and + * copying them to another part of the DOM, while maintaining their connection to the original AngularJS + * scope from where they were taken. + * + * Transclusion is used (often with {@link ngTransclude}) to insert the + * original contents of a directive's element into a specified place in the template of the directive. + * The benefit of transclusion, over simply moving the DOM elements manually, is that the transcluded + * content has access to the properties on the scope from which it was taken, even if the directive + * has isolated scope. + * See the {@link guide/directive#creating-a-directive-that-wraps-other-elements Directives Guide}. + * + * This makes it possible for the widget to have private state for its template, while the transcluded + * content has access to its originating scope. + * + *
+ * **Note:** When testing an element transclude directive you must not place the directive at the root of the + * DOM fragment that is being compiled. See {@link guide/unit-testing#testing-transclusion-directives + * Testing Transclusion Directives}. + *
+ * + * There are three kinds of transclusion depending upon whether you want to transclude just the contents of the + * directive's element, the entire element or multiple parts of the element contents: + * + * * `true` - transclude the content (i.e. the child nodes) of the directive's element. + * * `'element'` - transclude the whole of the directive's element including any directives on this + * element that are defined at a lower priority than this directive. When used, the `template` + * property is ignored. + * * **`{...}` (an object hash):** - map elements of the content onto transclusion "slots" in the template. + * + * **Multi-slot transclusion** is declared by providing an object for the `transclude` property. + * + * This object is a map where the keys are the name of the slot to fill and the value is an element selector + * used to match the HTML to the slot. The element selector should be in normalized form (e.g. `myElement`) + * and will match the standard element variants (e.g. `my-element`, `my:element`, `data-my-element`, etc). + * + * For further information check out the guide on {@link guide/directive#matching-directives Matching Directives}. + * + * If the element selector is prefixed with a `?` then that slot is optional. + * + * For example, the transclude object `{ slotA: '?myCustomElement' }` maps `` elements to + * the `slotA` slot, which can be accessed via the `$transclude` function or via the {@link ngTransclude} directive. + * + * Slots that are not marked as optional (`?`) will trigger a compile time error if there are no matching elements + * in the transclude content. If you wish to know if an optional slot was filled with content, then you can call + * `$transclude.isSlotFilled(slotName)` on the transclude function passed to the directive's link function and + * injectable into the directive's controller. + * + * + * #### Transclusion Functions + * + * When a directive requests transclusion, the compiler extracts its contents and provides a **transclusion + * function** to the directive's `link` function and `controller`. This transclusion function is a special + * **linking function** that will return the compiled contents linked to a new transclusion scope. + * + *
+ * If you are just using {@link ngTransclude} then you don't need to worry about this function, since + * ngTransclude will deal with it for us. + *
+ * + * If you want to manually control the insertion and removal of the transcluded content in your directive + * then you must use this transclude function. When you call a transclude function it returns a jqLite/JQuery + * object that contains the compiled DOM, which is linked to the correct transclusion scope. + * + * When you call a transclusion function you can pass in a **clone attach function**. This function accepts + * two parameters, `function(clone, scope) { ... }`, where the `clone` is a fresh compiled copy of your transcluded + * content and the `scope` is the newly created transclusion scope, which the clone will be linked to. + * + *
+ * **Best Practice**: Always provide a `cloneFn` (clone attach function) when you call a transclude function + * since you then get a fresh clone of the original DOM and also have access to the new transclusion scope. + *
+ * + * It is normal practice to attach your transcluded content (`clone`) to the DOM inside your **clone + * attach function**: + * + * ```js + * var transcludedContent, transclusionScope; + * + * $transclude(function(clone, scope) { + * element.append(clone); + * transcludedContent = clone; + * transclusionScope = scope; + * }); + * ``` + * + * Later, if you want to remove the transcluded content from your DOM then you should also destroy the + * associated transclusion scope: + * + * ```js + * transcludedContent.remove(); + * transclusionScope.$destroy(); + * ``` + * + *
+ * **Best Practice**: if you intend to add and remove transcluded content manually in your directive + * (by calling the transclude function to get the DOM and calling `element.remove()` to remove it), + * then you are also responsible for calling `$destroy` on the transclusion scope. + *
+ * + * The built-in DOM manipulation directives, such as {@link ngIf}, {@link ngSwitch} and {@link ngRepeat} + * automatically destroy their transcluded clones as necessary so you do not need to worry about this if + * you are simply using {@link ngTransclude} to inject the transclusion into your directive. + * + * + * #### Transclusion Scopes + * + * When you call a transclude function it returns a DOM fragment that is pre-bound to a **transclusion + * scope**. This scope is special, in that it is a child of the directive's scope (and so gets destroyed + * when the directive's scope gets destroyed) but it inherits the properties of the scope from which it + * was taken. + * + * For example consider a directive that uses transclusion and isolated scope. The DOM hierarchy might look + * like this: + * + * ```html + *
+ *
+ *
+ *
+ *
+ *
+ * ``` + * + * The `$parent` scope hierarchy will look like this: + * + ``` + - $rootScope + - isolate + - transclusion + ``` + * + * but the scopes will inherit prototypically from different scopes to their `$parent`. + * + ``` + - $rootScope + - transclusion + - isolate + ``` + * + * + * ### Attributes + * + * The {@link ng.$compile.directive.Attributes Attributes} object - passed as a parameter in the + * `link()` or `compile()` functions. It has a variety of uses. + * + * * *Accessing normalized attribute names:* Directives like `ngBind` can be expressed in many ways: + * `ng:bind`, `data-ng-bind`, or `x-ng-bind`. The attributes object allows for normalized access + * to the attributes. + * + * * *Directive inter-communication:* All directives share the same instance of the attributes + * object which allows the directives to use the attributes object as inter directive + * communication. + * + * * *Supports interpolation:* Interpolation attributes are assigned to the attribute object + * allowing other directives to read the interpolated value. + * + * * *Observing interpolated attributes:* Use `$observe` to observe the value changes of attributes + * that contain interpolation (e.g. `src="{{bar}}"`). Not only is this very efficient but it's also + * the only way to easily get the actual value because during the linking phase the interpolation + * hasn't been evaluated yet and so the value is at this time set to `undefined`. + * + * ```js + * function linkingFn(scope, elm, attrs, ctrl) { + * // get the attribute value + * console.log(attrs.ngModel); + * + * // change the attribute + * attrs.$set('ngModel', 'new value'); + * + * // observe changes to interpolated attribute + * attrs.$observe('ngModel', function(value) { + * console.log('ngModel has changed value to ' + value); + * }); + * } + * ``` + * + * ## Example + * + *
+ * **Note**: Typically directives are registered with `module.directive`. The example below is + * to illustrate how `$compile` works. + *

- *     var clonedElement = $compile(templateHTML)(scope, function(clonedElement, scope) {

+ *   ```js
+ *     var templateElement = angular.element('

');
+ *     var clonedElement = $compile(templateElement)(scope, function(clonedElement, scope) {
+ *       // Attach the clone to DOM document at the right place.

+ * **Note**: {@link $compile#-replace- `replace: true`} is deprecated and not recommended to use, + * mainly due to the issues listed here. It has been completely removed in the new Angular. + *
+ * + * #### Attribute values are not merged + * + * When a `replace` directive encounters the same attribute on the original and the replace node, + * it will simply deduplicate the attribute and join the values with a space or with a `;` in case of + * the `style` attribute. + * ```html + * Original Node: + * Replace Template: + * Result: + * ``` + * + * That means attributes that contain AngularJS expressions will not be merged correctly, e.g. + * {@link ngShow} or {@link ngClass} will cause a {@link $parse} error: + * + * ```html + * Original Node: + * Replace Template: + * Result: + * ``` + * + * See issue [#5695](https://github.com/angular/angular.js/issues/5695). + * + * #### Directives are not deduplicated before compilation + * + * When the original node and the replace template declare the same directive(s), they will be + * {@link guide/compiler#double-compilation-and-how-to-avoid-it compiled twice} because the compiler + * does not deduplicate them. In many cases, this is not noticeable, but e.g. {@link ngModel} will + * attach `$formatters` and `$parsers` twice. + * + * See issue [#2573](https://github.com/angular/angular.js/issues/2573). + * + * #### `transclude: element` in the replace template root can have unexpected effects + * + * When the replace template has a directive at the root node that uses + * {@link $compile#-transclude- `transclude: element`}, e.g. + * {@link ngIf} or {@link ngRepeat}, the DOM structure or scope inheritance can be incorrect. + * See the following issues: + * + * - Incorrect scope on replaced element: + * [#9837](https://github.com/angular/angular.js/issues/9837) + * - Different DOM between `template` and `templateUrl`: + * [#10612](https://github.com/angular/angular.js/issues/14326) + * */ +/** + * @ngdoc directive + * @name ngProp + * @restrict A + * @element ANY + * + * @usage + * + * ```html + * + * + * ``` + * + * or with uppercase letters in property (e.g. "propName"): + * + * + * ```html + * + * + * ``` + * + * + * @description + * The `ngProp` directive binds an expression to a DOM element property. + * `ngProp` allows writing to arbitrary properties by including + * the property name in the attribute, e.g. `ng-prop-value="'my value'"` binds 'my value' to + * the `value` property. + * + * Usually, it's not necessary to write to properties in AngularJS, as the built-in directives + * handle the most common use cases (instead of the above example, you would use {@link ngValue}). + * + * However, [custom elements](https://developer.mozilla.org/docs/Web/Web_Components/Using_custom_elements) + * often use custom properties to hold data, and `ngProp` can be used to provide input to these + * custom elements. + * + * ## Binding to camelCase properties + * + * Since HTML attributes are case-insensitive, camelCase properties like `innerHTML` must be escaped. + * AngularJS uses the underscore (_) in front of a character to indicate that it is uppercase, so + * `innerHTML` must be written as `ng-prop-inner_h_t_m_l="expression"` (Note that this is just an + * example, and for binding HTML {@link ngBindHtml} should be used. + * + * ## Security + * + * Binding expressions to arbitrary properties poses a security risk, as properties like `innerHTML` + * can insert potentially dangerous HTML into the application, e.g. script tags that execute + * malicious code. + * For this reason, `ngProp` applies Strict Contextual Escaping with the {@link ng.$sce $sce service}. + * This means vulnerable properties require their content to be "trusted", based on the + * context of the property. For example, the `innerHTML` is in the `HTML` context, and the + * `iframe.src` property is in the `RESOURCE_URL` context, which requires that values written to + * this property are trusted as a `RESOURCE_URL`. + * + * This can be set explicitly by calling $sce.trustAs(type, value) on the value that is + * trusted before passing it to the `ng-prop-*` directive. There are exist shorthand methods for + * each context type in the form of {@link ng.$sce#trustAsResourceUrl $sce.trustAsResourceUrl()} et al. + * + * In some cases you can also rely upon automatic sanitization of untrusted values - see below. + * + * Based on the context, other options may exist to mark a value as trusted / configure the behavior + * of {@link ng.$sce}. For example, to restrict the `RESOURCE_URL` context to specific origins, use + * the {@link $sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist()} + * and {@link $sceDelegateProvider#resourceUrlBlacklist resourceUrlBlacklist()}. + * + * {@link ng.$sce#what-trusted-context-types-are-supported- Find out more about the different context types}. + * + * ### HTML Sanitization + * + * By default, `$sce` will throw an error if it detects untrusted HTML content, and will not bind the + * content. + * However, if you include the {@link ngSanitize ngSanitize module}, it will try to sanitize the + * potentially dangerous HTML, e.g. strip non-whitelisted tags and attributes when binding to + * `innerHTML`. + * + * @example + * ### Binding to different contexts + * + * + * + * angular.module('exampleNgProp', []) + * .component('main', { + * templateUrl: 'main.html', + * controller: function($sce) { + * this.safeContent = 'Safe content'; + * this.unsafeContent = ''; + * this.trustedUnsafeContent = $sce.trustAsHtml(this.unsafeContent); + * } + * }); + * + * + *

While for simple usage patterns this doesn't matter much, for advanced usage + * it is important to familiarize yourself with these APIs and the guarantees they provide. + * + * + * ## General usage + * The `$http` service is a function which takes a single argument — a {@link $http#usage configuration object} — + * that is used to generate an HTTP request and returns a {@link ng.$q promise} that is + * resolved (request success) or rejected (request failure) with a + * {@link ng.$http#$http-returns response} object. + * + * ```js + * // Simple GET request example: + * $http({ + * method: 'GET', + * url: '/someUrl' + * }).then(function successCallback(response) { + * // this callback will be called asynchronously + * // when the response is available + * }, function errorCallback(response) { + * // called asynchronously if an error occurs + * // or server returns response with an error status. + * }); + * ``` + * + * + * ## Shortcut methods + * + * Shortcut methods are also available. All shortcut methods require passing in the URL, and + * request data must be passed in for POST/PUT requests. An optional config can be passed as the + * last argument. + * + * ```js + * $http.get('/someUrl', config).then(successCallback, errorCallback); + * $http.post('/someUrl', data, config).then(successCallback, errorCallback); + * ``` + * + * Complete list of shortcut methods: + * + * - {@link ng.$http#get $http.get} + * - {@link ng.$http#head $http.head} + * - {@link ng.$http#post $http.post} + * - {@link ng.$http#put $http.put} + * - {@link ng.$http#delete $http.delete} + * - {@link ng.$http#jsonp $http.jsonp} + * - {@link ng.$http#patch $http.patch} + * + * + * ## Writing Unit Tests that use $http + * When unit testing (using {@link ngMock ngMock}), it is necessary to call + * {@link ngMock.$httpBackend#flush $httpBackend.flush()} to flush each pending + * request using trained responses. + * + * ``` + * $httpBackend.expectGET(...); + * $http.get(...); + * $httpBackend.flush(); + * ``` + * + * ## Setting HTTP Headers + * + * The $http service will automatically add certain HTTP headers to all requests. These defaults + * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration + * object, which currently contains this default configuration: + * + * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): + * - Accept: application/json, text/plain, \*/\* + * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) + * - `Content-Type: application/json` + * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) + * - `Content-Type: application/json` + * + * To add or overwrite these defaults, simply add or remove a property from these configuration + * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object + * with the lowercased HTTP method name as the key, e.g. + * `$httpProvider.defaults.headers.get = { 'My-Header' : 'value' }`. + * + * The defaults can also be set at runtime via the `$http.defaults` object in the same + * fashion. For example: + * + * ``` + * module.run(function($http) { + * $http.defaults.headers.common.Authorization = 'Basic YmVlcDpib29w'; + * }); + * ``` + * + * In addition, you can supply a `headers` property in the config object passed when + * calling `$http(config)`, which overrides the defaults without changing them globally. + * + * To explicitly remove a header automatically added via $httpProvider.defaults.headers on a per request basis, + * Use the `headers` property, setting the desired header to `undefined`. For example: + * + * ```js + * var req = { + * method: 'POST', + * url: 'http://example.com', + * headers: { + * 'Content-Type': undefined + * }, + * data: { test: 'test' } + * } + * + * $http(req).then(function(){...}, function(){...}); + * ``` + * + * ## Transforming Requests and Responses + * + * Both requests and responses can be transformed using transformation functions: `transformRequest` + * and `transformResponse`. These properties can be a single function that returns + * the transformed value (`function(data, headersGetter, status)`) or an array of such transformation functions, + * which allows you to `push` or `unshift` a new transformation function into the transformation chain. + * + *
+ * **Note:** AngularJS does not make a copy of the `data` parameter before it is passed into the `transformRequest` pipeline. + * That means changes to the properties of `data` are not local to the transform function (since Javascript passes objects by reference). + * For example, when calling `$http.get(url, $scope.myObject)`, modifications to the object's properties in a transformRequest + * function will be reflected on the scope and in any templates where the object is data-bound. + * To prevent this, transform functions should have no side-effects. + * If you need to modify properties, it is recommended to make a copy of the data, or create new object to return. + *
+ * + * ### Default Transformations + * + * The `$httpProvider` provider and `$http` service expose `defaults.transformRequest` and + * `defaults.transformResponse` properties. If a request does not provide its own transformations + * then these will be applied. + * + * You can augment or replace the default transformations by modifying these properties by adding to or + * replacing the array. + * + * AngularJS provides the following default transformations: + * + * Request transformations (`$httpProvider.defaults.transformRequest` and `$http.defaults.transformRequest`) is + * an array with one function that does the following: + * + * - If the `data` property of the request configuration object contains an object, serialize it + * into JSON format. + * + * Response transformations (`$httpProvider.defaults.transformResponse` and `$http.defaults.transformResponse`) is + * an array with one function that does the following: + * + * - If XSRF prefix is detected, strip it (see Security Considerations section below). + * - If the `Content-Type` is `application/json` or the response looks like JSON, + * deserialize it using a JSON parser. + * + * + * ### Overriding the Default Transformations Per Request + * + * If you wish to override the request/response transformations only for a single request then provide + * `transformRequest` and/or `transformResponse` properties on the configuration object passed + * into `$http`. + * + * Note that if you provide these properties on the config object the default transformations will be + * overwritten. If you wish to augment the default transformations then you must include them in your + * local transformation array. + * + * The following code demonstrates adding a new response transformation to be run after the default response + * transformations have been run. + * + * ```js + * function appendTransform(defaults, transform) { + * + * // We can't guarantee that the default transformation is an array + * defaults = angular.isArray(defaults) ? defaults : [defaults]; + * + * // Append the new transformation to the defaults + * return defaults.concat(transform); + * } + * + * $http({ + * url: '...', + * method: 'GET', + * transformResponse: appendTransform($http.defaults.transformResponse, function(value) { + * return doTransform(value); + * }) + * }); + * ``` + * + * + * ## Caching + * + * {@link ng.$http `$http`} responses are not cached by default. To enable caching, you must + * set the config.cache value or the default cache value to TRUE or to a cache object (created + * with {@link ng.$cacheFactory `$cacheFactory`}). If defined, the value of config.cache takes + * precedence over the default cache value. + * + * In order to: + * * cache all responses - set the default cache value to TRUE or to a cache object + * * cache a specific response - set config.cache value to TRUE or to a cache object + * + * If caching is enabled, but neither the default cache nor config.cache are set to a cache object, + * then the default `$cacheFactory("$http")` object is used. + * + * The default cache value can be set by updating the + * {@link ng.$http#defaults `$http.defaults.cache`} property or the + * {@link $httpProvider#defaults `$httpProvider.defaults.cache`} property. + * + * When caching is enabled, {@link ng.$http `$http`} stores the response from the server using + * the relevant cache object. The next time the same request is made, the response is returned + * from the cache without sending a request to the server. + * + * Take note that: + * + * * Only GET and JSONP requests are cached. + * * The cache key is the request URL including search parameters; headers are not considered. + * * Cached responses are returned asynchronously, in the same way as responses from the server. + * * If multiple identical requests are made using the same cache, which is not yet populated, + * one request will be made to the server and remaining requests will return the same response. + * * A cache-control header on the response does not affect if or how responses are cached. + * + * + * ## Interceptors + * + * Before you start creating interceptors, be sure to understand the + * {@link ng.$q $q and deferred/promise APIs}. + * + * For purposes of global error handling, authentication, or any kind of synchronous or + * asynchronous pre-processing of request or postprocessing of responses, it is desirable to be + * able to intercept requests before they are handed to the server and + * responses before they are handed over to the application code that + * initiated these requests. The interceptors leverage the {@link ng.$q + * promise APIs} to fulfill this need for both synchronous and asynchronous pre-processing. + * + * The interceptors are service factories that are registered with the `$httpProvider` by + * adding them to the `$httpProvider.interceptors` array. The factory is called and + * injected with dependencies (if specified) and returns the interceptor. + * + * There are two kinds of interceptors (and two kinds of rejection interceptors): + * + * * `request`: interceptors get called with a http {@link $http#usage config} object. The function is free to + * modify the `config` object or create a new one. The function needs to return the `config` + * object directly, or a promise containing the `config` or a new `config` object. + * * `requestError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * * `response`: interceptors get called with http `response` object. The function is free to + * modify the `response` object or create a new one. The function needs to return the `response` + * object directly, or as a promise containing the `response` or a new `response` object. + * * `responseError`: interceptor gets called when a previous interceptor threw an error or + * resolved with a rejection. + * + * + * ```js + * // register the interceptor as a service + * $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) { + * return { + * // optional method + * 'request': function(config) { + * // do something on success + * return config; + * }, + * + * // optional method + * 'requestError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * }, + * + * + * + * // optional method + * 'response': function(response) { + * // do something on success + * return response; + * }, + * + * // optional method + * 'responseError': function(rejection) { + * // do something on error + * if (canRecover(rejection)) { + * return responseOrNewPromise + * } + * return $q.reject(rejection); + * } + * }; + * }); + * + * $httpProvider.interceptors.push('myHttpInterceptor'); + * + * + * // alternatively, register the interceptor via an anonymous factory + * $httpProvider.interceptors.push(function($q, dependency1, dependency2) { + * return { + * 'request': function(config) { + * // same as above + * }, + * + * 'response': function(response) { + * // same as above + * } + * }; + * }); + * ``` + * + * ## Security Considerations + * + * When designing web applications, consider security threats from: + * + * - [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * - [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) + * + * Both server and the client must cooperate in order to eliminate these threats. AngularJS comes + * pre-configured with strategies that address these issues, but for this to work backend server + * cooperation is required. + * + * ### JSON Vulnerability Protection + * + * A [JSON vulnerability](http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx) + * allows third party website to turn your JSON resource URL into + * [JSONP](http://en.wikipedia.org/wiki/JSONP) request under some conditions. To + * counter this your server can prefix all JSON requests with following string `")]}',\n"`. + * AngularJS will automatically strip the prefix before processing it as JSON. + * + * For example if your server needs to return: + * ```js + * ['one','two'] + * ``` + * + * which is vulnerable to attack, your server can return: + * ```js + * )]}', + * ['one','two'] + * ``` + * + * AngularJS will strip the prefix, before processing the JSON. + * + * + * ### Cross Site Request Forgery (XSRF) Protection + * + * [XSRF](http://en.wikipedia.org/wiki/Cross-site_request_forgery) is an attack technique by + * which the attacker can trick an authenticated user into unknowingly executing actions on your + * website. AngularJS provides a mechanism to counter XSRF. When performing XHR requests, the + * $http service reads a token from a cookie (by default, `XSRF-TOKEN`) and sets it as an HTTP + * header (by default `X-XSRF-TOKEN`). Since only JavaScript that runs on your domain could read + * the cookie, your server can be assured that the XHR came from JavaScript running on your + * domain. + * + * To take advantage of this, your server needs to set a token in a JavaScript readable session + * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the + * server can verify that the cookie matches the `X-XSRF-TOKEN` HTTP header, and therefore be + * sure that only JavaScript running on your domain could have sent the request. The token must + * be unique for each user and must be verifiable by the server (to prevent the JavaScript from + * making up its own tokens). We recommend that the token is a digest of your site's + * authentication cookie with a [salt](https://en.wikipedia.org/wiki/Salt_(cryptography)) + * for added security. + * + * The header will — by default — **not** be set for cross-domain requests. This + * prevents unauthorized servers (e.g. malicious or compromised 3rd-party APIs) from gaining + * access to your users' XSRF tokens and exposing them to Cross Site Request Forgery. If you + * want to, you can whitelist additional origins to also receive the XSRF token, by adding them + * to {@link ng.$httpProvider#xsrfWhitelistedOrigins xsrfWhitelistedOrigins}. This might be + * useful, for example, if your application, served from `example.com`, needs to access your API + * at `api.example.com`. + * See {@link ng.$httpProvider#xsrfWhitelistedOrigins $httpProvider.xsrfWhitelistedOrigins} for + * more details. + * + *
+ * **Warning**
+ * Only whitelist origins that you have control over and make sure you understand the + * implications of doing so. + *
+ * + * The name of the cookie and the header can be specified using the `xsrfCookieName` and + * `xsrfHeaderName` properties of either `$httpProvider.defaults` at config-time, + * `$http.defaults` at run-time, or the per-request config object. + * + * In order to prevent collisions in environments where multiple AngularJS apps share the + * same domain or subdomain, we recommend that each application uses a unique cookie name. + * + * + * @param {object} config Object describing the request to be made and how it should be + * processed. The object has following properties: + * + * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) + * - **url** – `{string|TrustedObject}` – Absolute or relative URL of the resource that is being requested; + * or an object created by a call to `$sce.trustAsResourceUrl(url)`. + * - **params** – `{Object.}` – Map of strings or objects which will be serialized + * with the `paramSerializer` and appended as GET parameters. + * - **data** – `{string|Object}` – Data to be sent as the request message data. + * - **headers** – `{Object}` – Map of strings or functions which return strings representing + * HTTP headers to send to the server. If the return value of a function is null, the + * header will not be sent. Functions accept a config object as an argument. + * - **eventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest object. + * To bind events to the XMLHttpRequest upload object, use `uploadEventHandlers`. + * The handler will be called in the context of a `$apply` block. + * - **uploadEventHandlers** - `{Object}` - Event listeners to be bound to the XMLHttpRequest upload + * object. To bind events to the XMLHttpRequest object, use `eventHandlers`. + * The handler will be called in the context of a `$apply` block. + * - **xsrfHeaderName** – `{string}` – Name of HTTP header to populate with the XSRF token. + * - **xsrfCookieName** – `{string}` – Name of cookie containing the XSRF token. + * - **transformRequest** – + * `{function(data, headersGetter)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * request body and headers and returns its transformed (typically serialized) version. + * See {@link ng.$http#overriding-the-default-transformations-per-request + * Overriding the Default Transformations} + * - **transformResponse** – + * `{function(data, headersGetter, status)|Array.}` – + * transform function or an array of such functions. The transform function takes the http + * response body, headers and status and returns its transformed (typically deserialized) version. + * See {@link ng.$http#overriding-the-default-transformations-per-request + * Overriding the Default Transformations} + * - **paramSerializer** - `{string|function(Object):string}` - A function used to + * prepare the string representation of request parameters (specified as an object). + * If specified as string, it is interpreted as function registered with the + * {@link $injector $injector}, which means you can create your own serializer + * by registering it as a {@link auto.$provide#service service}. + * The default serializer is the {@link $httpParamSerializer $httpParamSerializer}; + * alternatively, you can use the {@link $httpParamSerializerJQLike $httpParamSerializerJQLike} + * - **cache** – `{boolean|Object}` – A boolean value or object created with + * {@link ng.$cacheFactory `$cacheFactory`} to enable or disable caching of the HTTP response. + * See {@link $http#caching $http Caching} for more information. + * - **timeout** – `{number|Promise}` – timeout in milliseconds, or {@link ng.$q promise} + * that should abort the request when resolved. + * + * A numerical timeout or a promise returned from {@link ng.$timeout $timeout}, will set + * the `xhrStatus` in the {@link $http#$http-returns response} to "timeout", and any other + * resolved promise will set it to "abort", following standard XMLHttpRequest behavior. + * + * - **withCredentials** - `{boolean}` - whether to set the `withCredentials` flag on the + * XHR object. See [requests with credentials](https://developer.mozilla.org/docs/Web/HTTP/Access_control_CORS#Requests_with_credentials) + * for more information. + * - **responseType** - `{string}` - see + * [XMLHttpRequest.responseType](https://developer.mozilla.org/en-US/docs/Web/API/XMLHttpRequest#xmlhttprequest-responsetype). + * + * @returns {HttpPromise} A {@link ng.$q `Promise}` that will be resolved (request success) + * or rejected (request failure) with a response object. + * + * The response object has these properties: + * + * - **data** – `{string|Object}` – The response body transformed with + * the transform functions. + * - **status** – `{number}` – HTTP status code of the response. + * - **headers** – `{function([headerName])}` – Header getter function. + * - **config** – `{Object}` – The configuration object that was used + * to generate the request. + * - **statusText** – `{string}` – HTTP status text of the response. + * - **xhrStatus** – `{string}` – Status of the XMLHttpRequest + * (`complete`, `error`, `timeout` or `abort`). + * + * + * A response status code between 200 and 299 is considered a success status + * and will result in the success callback being called. Any response status + * code outside of that range is considered an error status and will result + * in the error callback being called. + * Also, status codes less than -1 are normalized to zero. -1 usually means + * the request was aborted, e.g. using a `config.timeout`. More information + * about the status might be available in the `xhrStatus` property. + * + * Note that if the response is a redirect, XMLHttpRequest will transparently + * follow it, meaning that the outcome (success or error) will be determined + * by the final response status code. + * + * + * @property {Array.} pendingRequests Array of config objects for currently pending + * requests. This is primarily meant to be used for debugging purposes. + * + * + * @example + + +

So, for HTML elements interpolated + * by {@link ng.$compile $compile}, or otherwise interpolated with the `mustHaveExpression` parameter + * set to `true`, the interpolated text must contain an unescaped interpolation expression.

Its goal is to assist in writing code in a way that (a) is secure by default, and + * (b) makes auditing for security vulnerabilities such as XSS, clickjacking, etc. a lot easier. + * + * ### Overview + * + * To systematically block XSS security bugs, AngularJS treats all values as untrusted by default in + * HTML or sensitive URL bindings. When binding untrusted values, AngularJS will automatically + * run security checks on them (sanitizations, whitelists, depending on context), or throw when it + * cannot guarantee the security of the result. That behavior depends strongly on contexts: HTML + * can be sanitized, but template URLs cannot, for instance. + * + * To illustrate this, consider the `ng-bind-html` directive. It renders its value directly as HTML: + * we call that the *context*. When given an untrusted input, AngularJS will attempt to sanitize it + * before rendering if a sanitizer is available, and throw otherwise. To bypass sanitization and + * render the input as-is, you will need to mark it as trusted for that context before attempting + * to bind it. + * + * As of version 1.2, AngularJS ships with SCE enabled by default. + * + * ### In practice + * + * Here's an example of a binding in a privileged context: + * + * ``` + * + *
+ * ``` + * + * Notice that `ng-bind-html` is bound to `userHtml` controlled by the user. With SCE + * disabled, this application allows the user to render arbitrary HTML into the DIV, which would + * be an XSS security bug. In a more realistic example, one may be rendering user comments, blog + * articles, etc. via bindings. (HTML is just one example of a context where rendering user + * controlled input creates security vulnerabilities.) + * + * For the case of HTML, you might use a library, either on the client side, or on the server side, + * to sanitize unsafe HTML before binding to the value and rendering it in the document. + * + * How would you ensure that every place that used these types of bindings was bound to a value that + * was sanitized by your library (or returned as safe for rendering by your server?) How can you + * ensure that you didn't accidentally delete the line that sanitized the value, or renamed some + * properties/fields and forgot to update the binding to the sanitized value? + * + * To be secure by default, AngularJS makes sure bindings go through that sanitization, or + * any similar validation process, unless there's a good reason to trust the given value in this + * context. That trust is formalized with a function call. This means that as a developer, you + * can assume all untrusted bindings are safe. Then, to audit your code for binding security issues, + * you just need to ensure the values you mark as trusted indeed are safe - because they were + * received from your server, sanitized by your library, etc. You can organize your codebase to + * help with this - perhaps allowing only the files in a specific directory to do this. + * Ensuring that the internal API exposed by that code doesn't markup arbitrary values as safe then + * becomes a more manageable task. + * + * In the case of AngularJS' SCE service, one uses {@link ng.$sce#trustAs $sce.trustAs} + * (and shorthand methods such as {@link ng.$sce#trustAsHtml $sce.trustAsHtml}, etc.) to + * build the trusted versions of your values. + * + * ### How does it work? + * + * In privileged contexts, directives and code will bind to the result of {@link ng.$sce#getTrusted + * $sce.getTrusted(context, value)} rather than to the value directly. Think of this function as + * a way to enforce the required security context in your data sink. Directives use {@link + * ng.$sce#parseAs $sce.parseAs} rather than `$parse` to watch attribute bindings, which performs + * the {@link ng.$sce#getTrusted $sce.getTrusted} behind the scenes on non-constant literals. Also, + * when binding without directives, AngularJS will understand the context of your bindings + * automatically. + * + * As an example, {@link ng.directive:ngBindHtml ngBindHtml} uses {@link + * ng.$sce#parseAsHtml $sce.parseAsHtml(binding expression)}. Here's the actual code (slightly + * simplified): + * + * ``` + * var ngBindHtmlDirective = ['$sce', function($sce) { + * return function(scope, element, attr) { + * scope.$watch($sce.parseAsHtml(attr.ngBindHtml), function(value) { + * element.html(value || ''); + * }); + * }; + * }]; + * ``` + * + * ### Impact on loading templates + * + * This applies both to the {@link ng.directive:ngInclude `ng-include`} directive as well as + * `templateUrl`'s specified by {@link guide/directive directives}. + * + * By default, AngularJS only loads templates from the same domain and protocol as the application + * document. This is done by calling {@link ng.$sce#getTrustedResourceUrl + * $sce.getTrustedResourceUrl} on the template URL. To load templates from other domains and/or + * protocols, you may either {@link ng.$sceDelegateProvider#resourceUrlWhitelist whitelist + * them} or {@link ng.$sce#trustAsResourceUrl wrap it} into a trusted value. + * + * *Please note*: + * The browser's + * [Same Origin Policy](https://code.google.com/p/browsersec/wiki/Part2#Same-origin_policy_for_XMLHttpRequest) + * and [Cross-Origin Resource Sharing (CORS)](http://www.w3.org/TR/cors/) + * policy apply in addition to this and may further restrict whether the template is successfully + * loaded. This means that without the right CORS policy, loading templates from a different domain + * won't work on all browsers. Also, loading templates from `file://` URL does not work on some + * browsers. + * + * ### This feels like too much overhead + * + * It's important to remember that SCE only applies to interpolation expressions. + * + * If your expressions are constant literals, they're automatically trusted and you don't need to + * call `$sce.trustAs` on them (e.g. + * `
`) just works (remember to include the + * `ngSanitize` module). The `$sceDelegate` will also use the `$sanitize` service if it is available + * when binding untrusted values to `$sce.HTML` context. + * AngularJS provides an implementation in `angular-sanitize.js`, and if you + * wish to use it, you will also need to depend on the {@link ngSanitize `ngSanitize`} module in + * your application. + * + * The included {@link ng.$sceDelegate $sceDelegate} comes with sane defaults to allow you to load + * templates in `ng-include` from your application's domain without having to even know about SCE. + * It blocks loading templates from other domains or loading templates over http from an https + * served document. You can change these by setting your own custom {@link + * ng.$sceDelegateProvider#resourceUrlWhitelist whitelists} and {@link + * ng.$sceDelegateProvider#resourceUrlBlacklist blacklists} for matching such URLs. + * + * This significantly reduces the overhead. It is far easier to pay the small overhead and have an + * application that's secure and can be audited to verify that with much more ease than bolting + * security onto an application later. + * + * + * ### What trusted context types are supported? + * + * | Context | Notes | + * |---------------------|----------------| + * | `$sce.HTML` | For HTML that's safe to source into the application. The {@link ng.directive:ngBindHtml ngBindHtml} directive uses this context for bindings. If an unsafe value is encountered and the {@link ngSanitize $sanitize} module is present this will sanitize the value instead of throwing an error. | + * | `$sce.CSS` | For CSS that's safe to source into the application. Currently unused. Feel free to use it in your own directives. | + * | `$sce.MEDIA_URL` | For URLs that are safe to render as media. Is automatically converted from string by sanitizing when needed. | + * | `$sce.URL` | For URLs that are safe to follow as links. Is automatically converted from string by sanitizing when needed. Note that `$sce.URL` makes a stronger statement about the URL than `$sce.MEDIA_URL` does and therefore contexts requiring values trusted for `$sce.URL` can be used anywhere that values trusted for `$sce.MEDIA_URL` are required.| + * | `$sce.RESOURCE_URL` | For URLs that are not only safe to follow as links, but whose contents are also safe to include in your application. Examples include `ng-include`, `src` / `ngSrc` bindings for tags other than `IMG` (e.g. `IFRAME`, `OBJECT`, etc.)

Note that `$sce.RESOURCE_URL` makes a stronger statement about the URL than `$sce.URL` or `$sce.MEDIA_URL` do and therefore contexts requiring values trusted for `$sce.RESOURCE_URL` can be used anywhere that values trusted for `$sce.URL` or `$sce.MEDIA_URL` are required.

The {@link $sceDelegateProvider#resourceUrlWhitelist $sceDelegateProvider#resourceUrlWhitelist()} and {@link $sceDelegateProvider#resourceUrlBlacklist $sceDelegateProvider#resourceUrlBlacklist()} can be used to restrict trusted origins for `RESOURCE_URL` | + * | `$sce.JS` | For JavaScript that is safe to execute in your application's context. Currently unused. Feel free to use it in your own directives. | + * + * + *
+ * Be aware that, before AngularJS 1.7.0, `a[href]` and `img[src]` used to sanitize their + * interpolated values directly rather than rely upon {@link ng.$sce#getTrusted `$sce.getTrusted`}. + * + * **As of 1.7.0, this is no longer the case.** + * + * Now such interpolations are marked as requiring `$sce.URL` (for `a[href]`) or `$sce.MEDIA_URL` + * (for `img[src]`), so that the sanitization happens (via `$sce.getTrusted...`) when the `$interpolate` + * service evaluates the expressions. + *
+ * + * There are no CSS or JS context bindings in AngularJS currently, so their corresponding `$sce.trustAs` + * functions aren't useful yet. This might evolve. + * + * ### Format of items in {@link ng.$sceDelegateProvider#resourceUrlWhitelist resourceUrlWhitelist}/{@link ng.$sceDelegateProvider#resourceUrlBlacklist Blacklist} + * + * Each element in these arrays must be one of the following: + * + * - **'self'** + * - The special **string**, `'self'`, can be used to match against all URLs of the **same + * domain** as the application document using the **same protocol**. + * - **String** (except the special value `'self'`) + * - The string is matched against the full *normalized / absolute URL* of the resource + * being tested (substring matches are not good enough.) + * - There are exactly **two wildcard sequences** - `*` and `**`. All other characters + * match themselves. + * - `*`: matches zero or more occurrences of any character other than one of the following 6 + * characters: '`:`', '`/`', '`.`', '`?`', '`&`' and '`;`'. It's a useful wildcard for use + * in a whitelist. + * - `**`: matches zero or more occurrences of *any* character. As such, it's not + * appropriate for use in a scheme, domain, etc. as it would match too much. (e.g. + * http://**.example.com/ would match http://evil.com/?ignore=.example.com/ and that might + * not have been the intention.) Its usage at the very end of the path is ok. (e.g. + * http://foo.example.com/templates/**). + * - **RegExp** (*see caveat below*) + * - *Caveat*: While regular expressions are powerful and offer great flexibility, their syntax + * (and all the inevitable escaping) makes them *harder to maintain*. It's easy to + * accidentally introduce a bug when one updates a complex expression (imho, all regexes should + * have good test coverage). For instance, the use of `.` in the regex is correct only in a + * small number of cases. A `.` character in the regex used when matching the scheme or a + * subdomain could be matched against a `:` or literal `.` that was likely not intended. It + * is highly recommended to use the string patterns and only fall back to regular expressions + * as a last resort. + * - The regular expression must be an instance of RegExp (i.e. not a string.) It is + * matched against the **entire** *normalized / absolute URL* of the resource being tested + * (even when the RegExp did not have the `^` and `$` codes.) In addition, any flags + * present on the RegExp (such as multiline, global, ignoreCase) are ignored. + * - If you are generating your JavaScript from some other templating engine (not + * recommended, e.g. in issue [#4006](https://github.com/angular/angular.js/issues/4006)), + * remember to escape your regular expression (and be aware that you might need more than + * one level of escaping depending on your templating engine and the way you interpolated + * the value.) Do make use of your platform's escaping mechanism as it might be good + * enough before coding your own. E.g. Ruby has + * [Regexp.escape(str)](http://www.ruby-doc.org/core-2.0.0/Regexp.html#method-c-escape) + * and Python has [re.escape](http://docs.python.org/library/re.html#re.escape). + * Javascript lacks a similar built in function for escaping. Take a look at Google + * Closure library's [goog.string.regExpEscape(s)]( + * http://docs.closure-library.googlecode.com/git/closure_goog_string_string.js.source.html#line962). + * + * Refer {@link ng.$sceDelegateProvider $sceDelegateProvider} for an example. + * + * ### Show me an example using SCE. + * + * + * + *

While for simple usage patterns this doesn't matter much, for advanced usage - * it is important to familiarize yourself with these APIs and the guarantees they provide. - * - * - * # General usage - * The `$http` service is a function which takes a single argument — a configuration object — - * that is used to generate an HTTP request and returns a {@link ng.$q promise} - * with two $http specific methods: `success` and `error`. - * - * 
-     *   $http({method: 'GET', url: '/someUrl'}).
-     *     success(function(data, status, headers, config) {
-     *       // this callback will be called asynchronously
-     *       // when the response is available
-     *     }).
-     *     error(function(data, status, headers, config) {
-     *       // called asynchronously if an error occurs
-     *       // or server returns response with an error status.
-     *     });
-     *
- * - * Since the returned value of calling the $http function is a `promise`, you can also use - * the `then` method to register callbacks, and these callbacks will receive a single argument – - * an object representing the response. See the API signature and type info below for more - * details. - * - * A response status code between 200 and 299 is considered a success status and - * will result in the success callback being called. Note that if the response is a redirect, - * XMLHttpRequest will transparently follow it, meaning that the error callback will not be - * called for such responses. - * - * # Shortcut methods - * - * Since all invocations of the $http service require passing in an HTTP method and URL, and - * POST/PUT requests require request data to be provided as well, shortcut methods - * were created: - * - * 
-     *   $http.get('/someUrl').success(successCallback);
-     *   $http.post('/someUrl', data).success(successCallback);
-     *
- * - * Complete list of shortcut methods: - * - * - {@link ng.$http#get $http.get} - * - {@link ng.$http#head $http.head} - * - {@link ng.$http#post $http.post} - * - {@link ng.$http#put $http.put} - * - {@link ng.$http#delete $http.delete} - * - {@link ng.$http#jsonp $http.jsonp} - * - * - * # Setting HTTP Headers - * - * The $http service will automatically add certain HTTP headers to all requests. These defaults - * can be fully configured by accessing the `$httpProvider.defaults.headers` configuration - * object, which currently contains this default configuration: - * - * - `$httpProvider.defaults.headers.common` (headers that are common for all requests): - * - `Accept: application/json, text/plain, * / *` - * - `X-Requested-With: XMLHttpRequest` - * - `$httpProvider.defaults.headers.post`: (header defaults for POST requests) - * - `Content-Type: application/json` - * - `$httpProvider.defaults.headers.put` (header defaults for PUT requests) - * - `Content-Type: application/json` - * - * To add or overwrite these defaults, simply add or remove a property from these configuration - * objects. To add headers for an HTTP method other than POST or PUT, simply add a new object - * with the lowercased HTTP method name as the key, e.g. - * `$httpProvider.defaults.headers.get['My-Header']='value'`. - * - * Additionally, the defaults can be set at runtime via the `$http.defaults` object in the same - * fashion. - * - * - * # Transforming Requests and Responses - * - * Both requests and responses can be transformed using transform functions. By default, Angular - * applies these transformations: - * - * Request transformations: - * - * - If the `data` property of the request configuration object contains an object, serialize it into - * JSON format. - * - * Response transformations: - * - * - If XSRF prefix is detected, strip it (see Security Considerations section below). - * - If JSON response is detected, deserialize it using a JSON parser. - * - * To globally augment or override the default transforms, modify the `$httpProvider.defaults.transformRequest` and - * `$httpProvider.defaults.transformResponse` properties. These properties are by default an - * array of transform functions, which allows you to `push` or `unshift` a new transformation function into the - * transformation chain. You can also decide to completely override any default transformations by assigning your - * transformation functions to these properties directly without the array wrapper. - * - * Similarly, to locally override the request/response transforms, augment the `transformRequest` and/or - * `transformResponse` properties of the configuration object passed into `$http`. - * - * - * # Caching - * - * To enable caching, set the configuration property `cache` to `true`. When the cache is - * enabled, `$http` stores the response from the server in local cache. Next time the - * response is served from the cache without sending a request to the server. - * - * Note that even if the response is served from cache, delivery of the data is asynchronous in - * the same way that real requests are. - * - * If there are multiple GET requests for the same URL that should be cached using the same - * cache, but the cache is not populated yet, only one request to the server will be made and - * the remaining requests will be fulfilled using the response from the first request. - * - * - * # Response interceptors - * - * Before you start creating interceptors, be sure to understand the - * {@link ng.$q $q and deferred/promise APIs}. - * - * For purposes of global error handling, authentication or any kind of synchronous or - * asynchronous preprocessing of received responses, it is desirable to be able to intercept - * responses for http requests before they are handed over to the application code that - * initiated these requests. The response interceptors leverage the {@link ng.$q - * promise apis} to fulfil this need for both synchronous and asynchronous preprocessing. - * - * The interceptors are service factories that are registered with the $httpProvider by - * adding them to the `$httpProvider.responseInterceptors` array. The factory is called and - * injected with dependencies (if specified) and returns the interceptor — a function that - * takes a {@link ng.$q promise} and returns the original or a new promise. - * - * 
-     *   // register the interceptor as a service
-     *   $provide.factory('myHttpInterceptor', function($q, dependency1, dependency2) {
-     *     return function(promise) {
-     *       return promise.then(function(response) {
-     *         // do something on success
-     *         return response;

- * - * - * # Security Considerations - * - * When designing web applications, consider security threats from: - * - * - {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx - * JSON vulnerability} - * - {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} - * - * Both server and the client must cooperate in order to eliminate these threats. Angular comes - * pre-configured with strategies that address these issues, but for this to work backend server - * cooperation is required. - * - * ## JSON Vulnerability Protection - * - * A {@link http://haacked.com/archive/2008/11/20/anatomy-of-a-subtle-json-vulnerability.aspx - * JSON vulnerability} allows third party website to turn your JSON resource URL into - * {@link http://en.wikipedia.org/wiki/JSONP JSONP} request under some conditions. To - * counter this your server can prefix all JSON requests with following string `")]}',\n"`. - * Angular will automatically strip the prefix before processing it as JSON. - * - * For example if your server needs to return: - * 
-     * ['one','two']
-     *
- * - * which is vulnerable to attack, your server can return: - * 
-     * )]}',
-     * ['one','two']
-     *
- * - * Angular will strip the prefix, before processing the JSON. - * - * - * ## Cross Site Request Forgery (XSRF) Protection - * - * {@link http://en.wikipedia.org/wiki/Cross-site_request_forgery XSRF} is a technique by which - * an unauthorized site can gain your user's private data. Angular provides a mechanism - * to counter XSRF. When performing XHR requests, the $http service reads a token from a cookie - * called `XSRF-TOKEN` and sets it as the HTTP header `X-XSRF-TOKEN`. Since only JavaScript that - * runs on your domain could read the cookie, your server can be assured that the XHR came from - * JavaScript running on your domain. - * - * To take advantage of this, your server needs to set a token in a JavaScript readable session - * cookie called `XSRF-TOKEN` on the first HTTP GET request. On subsequent XHR requests the - * server can verify that the cookie matches `X-XSRF-TOKEN` HTTP header, and therefore be sure - * that only JavaScript running on your domain could have sent the request. The token must be - * unique for each user and must be verifiable by the server (to prevent the JavaScript from making - * up its own tokens). We recommend that the token is a digest of your site's authentication - * cookie with a {@link https://en.wikipedia.org/wiki/Salt_(cryptography) salt} for added security. - * - * - * @param {object} config Object describing the request to be made and how it should be - * processed. The object has following properties: - * - * - **method** – `{string}` – HTTP method (e.g. 'GET', 'POST', etc) - * - **url** – `{string}` – Absolute or relative URL of the resource that is being requested. - * - **params** – `{Object.}` – Map of strings or objects which will be turned to - * `?key1=value1&key2=value2` after the url. If the value is not a string, it will be JSONified. - * - **data** – `{string|Object}` – Data to be sent as the request message data. - * - **headers** – `{Object}` – Map of strings representing HTTP headers to send to the server. - * - **transformRequest** – `{function(data, headersGetter)|Array.}` – - * transform function or an array of such functions. The transform function takes the http - * request body and headers and returns its transformed (typically serialized) version. - * - **transformResponse** – `{function(data, headersGetter)|Array.}` – - * transform function or an array of such functions. The transform function takes the http - * response body and headers and returns its transformed (typically deserialized) version. - * - **cache** – `{boolean|Cache}` – If true, a default $http cache will be used to cache the - * GET request, otherwise if a cache instance built with - * {@link ng.$cacheFactory $cacheFactory}, this cache will be used for - * caching. - * - **timeout** – `{number}` – timeout in milliseconds. - * - **withCredentials** - `{boolean}` - whether to to set the `withCredentials` flag on the - * XHR object. See {@link https://developer.mozilla.org/en/http_access_control#section_5 - * requests with credentials} for more information. - * - * @returns {HttpPromise} Returns a {@link ng.$q promise} object with the - * standard `then` method and two http specific methods: `success` and `error`. The `then` - * method takes two arguments a success and an error callback which will be called with a - * response object. The `success` and `error` methods take a single argument - a function that - * will be called when the request succeeds or fails respectively. The arguments passed into - * these functions are destructured representation of the response object passed into the - * `then` method. The response object has these properties: - * - * - **data** – `{string|Object}` – The response body transformed with the transform functions. - * - **status** – `{number}` – HTTP status code of the response. - * - **headers** – `{function([headerName])}` – Header getter function. - * - **config** – `{Object}` – The configuration object that was used to generate the request. - * - * @property {Array.} pendingRequests Array of config objects for currently pending - * requests. This is primarily meant to be used for debugging purposes. - * - * - * @example - - -

The `expression` is evaluated against each item and the output is used + * for comparing with other items. + * + * You can change the sorting order by setting `reverse` to `true`. By default, items are sorted in + * ascending order. + * + * The comparison is done using the `comparator` function. If none is specified, a default, built-in + * comparator is used (see below for details - in a nutshell, it compares numbers numerically and + * strings alphabetically). + * + * ### Under the hood + * + * Ordering the specified `collection` happens in two phases: + * + * 1. All items are passed through the predicate (or predicates), and the returned values are saved + * along with their type (`string`, `number` etc). For example, an item `{label: 'foo'}`, passed + * through a predicate that extracts the value of the `label` property, would be transformed to: + * ``` + * { + * value: 'foo', + * type: 'string', + * index: ... + * } + * ``` + * **Note:** `null` values use `'null'` as their type. + * 2. The comparator function is used to sort the items, based on the derived values, types and + * indices. + * + * If you use a custom comparator, it will be called with pairs of objects of the form + * `{value: ..., type: '...', index: ...}` and is expected to return `0` if the objects are equal + * (as far as the comparator is concerned), `-1` if the 1st one should be ranked higher than the + * second, or `1` otherwise. + * + * In order to ensure that the sorting will be deterministic across platforms, if none of the + * specified predicates can distinguish between two items, `orderBy` will automatically introduce a + * dummy predicate that returns the item's index as `value`. + * (If you are using a custom comparator, make sure it can handle this predicate as well.) + * + * If a custom comparator still can't distinguish between two items, then they will be sorted based + * on their index using the built-in comparator. + * + * Finally, in an attempt to simplify things, if a predicate returns an object as the extracted + * value for an item, `orderBy` will try to convert that object to a primitive value, before passing + * it to the comparator. The following rules govern the conversion: + * + * 1. If the object has a `valueOf()` method that returns a primitive, its return value will be + * used instead.
+ * (If the object has a `valueOf()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 2. If the object has a custom `toString()` method (i.e. not the one inherited from `Object`) that + * returns a primitive, its return value will be used instead.
+ * (If the object has a `toString()` method that returns another object, then the returned object + * will be used in subsequent steps.) + * 3. No conversion; the object itself is used. + * + * ### The default comparator + * + * The default, built-in comparator should be sufficient for most usecases. In short, it compares + * numbers numerically, strings alphabetically (and case-insensitively), for objects falls back to + * using their index in the original collection, sorts values of different types by type and puts + * `undefined` and `null` values at the end of the sorted list. + * + * More specifically, it follows these steps to determine the relative order of items: + * + * 1. If the compared values are of different types: + * - If one of the values is undefined, consider it "greater than" the other. + * - Else if one of the values is null, consider it "greater than" the other. + * - Else compare the types themselves alphabetically. + * 2. If both values are of type `string`, compare them alphabetically in a case- and + * locale-insensitive way. + * 3. If both values are objects, compare their indices instead. + * 4. Otherwise, return: + * - `0`, if the values are equal (by strict equality comparison, i.e. using `===`). + * - `-1`, if the 1st value is "less than" the 2nd value (compared using the `<` operator). + * - `1`, otherwise. + * + * **Note:** If you notice numbers not being sorted as expected, make sure they are actually being + * saved as numbers and not strings. + * **Note:** For the purpose of sorting, `null` and `undefined` are considered "greater than" + * any other value (with undefined "greater than" null). This effectively means that `null` + * and `undefined` values end up at the end of a list sorted in ascending order. + * **Note:** `null` values use `'null'` as their type to be able to distinguish them from objects. + * + * @param {Array|ArrayLike} collection - The collection (array or array-like object) to sort. + * @param {(Function|string|Array.)=} expression - A predicate (or list of + * predicates) to be used by the comparator to determine the order of elements. * * Can be one of: * - * - `function`: Getter function. The result of this function will be sorted using the - * `<`, `=`, `>` operator. - * - `string`: An Angular expression which evaluates to an object to order by, such as 'name' - * to sort by a property called 'name'. Optionally prefixed with `+` or `-` to control - * ascending or descending sort order (for example, +name or -name). - * - `Array`: An array of function or string predicates. The first predicate in the array - * is used for sorting, but when two items are equivalent, the next predicate is used. + * - `Function`: A getter function. This function will be called with each item as argument and + * the return value will be used for sorting. + * - `string`: An AngularJS expression. This expression will be evaluated against each item and the + * result will be used for sorting. For example, use `'label'` to sort by a property called + * `label` or `'label.substring(0, 3)'` to sort by the first 3 characters of the `label` + * property.
+ * (The result of a constant expression is interpreted as a property name to be used for + * comparison. For example, use `'"special name"'` (note the extra pair of quotes) to sort by a + * property called `special name`.)
+ * An expression can be optionally prefixed with `+` or `-` to control the sorting direction, + * ascending or descending. For example, `'+label'` or `'-label'`. If no property is provided, + * (e.g. `'+'` or `'-'`), the collection element itself is used in comparisons. + * - `Array`: An array of function and/or string predicates. If a predicate cannot determine the + * relative order of two items, the next predicate is used as a tie-breaker. + * + * **Note:** If the predicate is missing or empty then it defaults to `'+'`. + * + * @param {boolean=} reverse - If `true`, reverse the sorting order. + * @param {(Function)=} comparator - The comparator function used to determine the relative order of + * value pairs. If omitted, the built-in comparator will be used. + * + * @returns {Array} - The sorted array. * - * @param {boolean=} reverse Reverse the order the array. - * @returns {Array} Sorted copy of the source array. * * @example - - - -

+ * In plain HTML forms, the `name` attribute is used to identify groups of radio inputs, so + * that the browser can manage their state (checked/unchecked) based on the state of other + * inputs in the same group. + *

+ *

+ * In AngularJS forms, this is not necessary. The input's state will be updated based on the + * value of the underlying model data. + *

+ *
+ * + *
+ * If you omit the `name` attribute on a radio input, `ngModel` will automatically assign it a + * unique name. + *
+ * + * @param {string} ngModel Assignable AngularJS expression to data-bind to. + * @param {string} value The value to which the `ngModel` expression should be set when selected. + * Note that `value` only supports `string` values, i.e. the scope model needs to be a string, + * too.

Model binding, + * validation and number parsing are nevertheless supported. + * + * Browsers that support range (latest Chrome, Safari, Firefox, Edge) treat `input[range]` + * in a way that never allows the input to hold an invalid value. That means: + * - any non-numerical value is set to `(max + min) / 2`. + * - any numerical value that is less than the current min val, or greater than the current max val + * is set to the min / max val respectively. + * - additionally, the current `step` is respected, so the nearest value that satisfies a step + * is used. + * + * See the [HTML Spec on input[type=range]](https://www.w3.org/TR/html5/forms.html#range-state-(type=range)) + * for more info. + * + * This has the following consequences for AngularJS: + * + * Since the element value should always reflect the current model value, a range input + * will set the bound ngModel expression to the value that the browser has set for the + * input element. For example, in the following input ``, + * if the application sets `model.value = null`, the browser will set the input to `'50'`. + * AngularJS will then set the model to `50`, to prevent input and model value being out of sync. + * + * That means the model for range will immediately be set to `50` after `ngModel` has been + * initialized. It also means a range input can never have the required error. + * + * This does not only affect changes to the model value, but also to the values of the `min`, + * `max`, and `step` attributes. When these change in a way that will cause the browser to modify + * the input value, AngularJS will also update the model value. + * + * Automatic value adjustment also means that a range input element can never have the `required`, + * `min`, or `max` errors. + * + * However, `step` is currently only fully implemented by Firefox. Other browsers have problems + * when the step value changes dynamically - they do not adjust the element value correctly, but + * instead may set the `stepMismatch` error. If that's the case, the AngularJS will set the `step` + * error on the input, and set the model to `undefined`. + * + * Note that `input[range]` is not compatible with`ngMax`, `ngMin`, and `ngStep`, because they do + * not set the `min` and `max` attributes, which means that the browser won't automatically adjust + * the input value based on their values, and will always assume min = 0, max = 100, and step = 1. + * + * @param {string} ngModel Assignable AngularJS expression to data-bind to. + * @param {string=} name Property name of the form under which the control is published. + * @param {string=} min Sets the `min` validation to ensure that the value entered is greater + * than `min`.

  *
  * @description
- * Creates a binding that will innerHTML the result of evaluating the `expression` into the current
- * element. *The innerHTML-ed content will not be sanitized!* You should use this directive only if
- * {@link ngSanitize.directive:ngBindHtml ngBindHtml} directive is too
- * restrictive and when you absolutely trust the source of the content you are binding to.
+ * Evaluates the expression and inserts the resulting HTML into the element in a secure way. By default,
+ * the resulting HTML content will be sanitized using the {@link ngSanitize.$sanitize $sanitize} service.
+ * To utilize this functionality, ensure that `$sanitize` is available, for example, by including {@link
+ * ngSanitize} in your module's dependencies (not in core AngularJS). In order to use {@link ngSanitize}
+ * in your module's dependencies, you need to include "angular-sanitize.js" in your application.
  *
- * See {@link ngSanitize.$sanitize $sanitize} docs for examples.
+ * You may also bypass sanitization for values you know are safe. To do so, bind to
+ * an explicitly trusted value via {@link ng.$sce#trustAsHtml $sce.trustAsHtml}.  See the example
+ * under {@link ng.$sce#show-me-an-example-using-sce- Strict Contextual Escaping (SCE)}.
+ *
+ * Note: If a `$sanitize` service is unavailable and the bound value isn't explicitly trusted, you
+ * will have an exception (instead of an exploit.)

- * The `ngClass` allows you to set CSS classes on HTML an element, dynamically, by databinding
+ * The `ngClass` directive allows you to dynamically set CSS classes on an HTML element by databinding
  * an expression that represents all classes to be added.
  *
+ * The directive operates in three different ways, depending on which of three types the expression
+ * evaluates to:
+ *
+ * 1. If the expression evaluates to a string, the string should be one or more space-delimited class
+ * names.
+ *
+ * 2. If the expression evaluates to an object, then for each key-value pair of the
+ * object with a truthy value the corresponding key is used as a class name.
+ *
+ * 3. If the expression evaluates to an array, each element of the array should either be a string as in
+ * type 1 or an object as in type 2. This means that you can mix strings and objects together in an array
+ * to give you more control over what CSS classes appear. See the code below for an example of this.
+ *
+ *
  * The directive won't add duplicate classes if a particular class was already set.
  *
- * When the expression changes, the previously added classes are removed and only then the
- * new classes are added.

  *

- * For us to be compatible, we just need to implement the "getterFn" in $parse without violating
- * any of these restrictions.
+ * If you intend to implement CSP with these rules then you must tell AngularJS not to use these
+ * features.
  *
- * AngularJS uses `Function(string)` generated functions as a speed optimization. By applying `ngCsp`
- * it is be possible to opt into the CSP compatible mode. When this mode is on AngularJS will
- * evaluate all expressions up to 30% slower than in non-CSP mode, but no security violations will
- * be raised.

  *
- * In order to use this feature put `ngCsp` directive on the root element of the application.

+ *
+ * * The use of `eval()`, `Function(string)` and similar functions to dynamically create and execute

+ * provide a 30% increase in the speed of evaluating AngularJS expressions. (This CSP rule can be
+ * disabled with the CSP keyword `unsafe-eval`, but it is generally not recommended as it would

+ * @description
+ * The `ngIf` directive removes or recreates a portion of the DOM tree based on an
+ * {expression}. If the expression assigned to `ngIf` evaluates to a false
+ * value then the element is removed from the DOM, otherwise a clone of the
+ * element is reinserted into the DOM.
+ *
+ * `ngIf` differs from `ngShow` and `ngHide` in that `ngIf` completely removes and recreates the
+ * element in the DOM rather than changing its visibility via the `display` css property.  A common
+ * case when this difference is significant is when using css selectors that rely on an element's
+ * position within the DOM, such as the `:first-child` or `:last-child` pseudo-classes.
+ *
+ * Note that when an element is removed using `ngIf` its scope is destroyed and a new scope
+ * is created when the element is restored.  The scope created within `ngIf` inherits from
+ * its parent scope using
+ * [prototypal inheritance](https://github.com/angular/angular.js/wiki/Understanding-Scopes#javascript-prototypal-inheritance).
+ * An important implication of this is if `ngModel` is used within `ngIf` to bind to
+ * a javascript primitive defined in the parent scope. In this case any modifications made to the
+ * variable within the child scope will override (hide) the value in the parent scope.
+ *
+ * Also, `ngIf` recreates elements using their compiled state. An example of this behavior

  * @ngdoc directive
- * @name ng.directive:ngInit
- *
- * @description
- * The `ngInit` directive specifies initialization tasks to be executed
- *  before the template enters execution mode during bootstrap.
- *
+ * @name ngInit
+ * @restrict AC
+ * @priority 450
  * @element ANY
+ *
  * @param {expression} ngInit {@link guide/expression Expression} to eval.
  *
+ * @description
+ * The `ngInit` directive allows you to evaluate an expression in the
+ * current scope.
+ *
+ * 
      
+ * This directive can be abused to add unnecessary amounts of logic into your templates.
+ * There are only a few appropriate uses of `ngInit`:
+ * 
        
+ *   
      • aliasing special properties of {@link ng.directive:ngRepeat `ngRepeat`},
+ *     as seen in the demo below.
        • 
+ *   
      • initializing data during development, or for examples, as seen throughout these docs.
        • 
+ *   
      • injecting data via server side scripting.
        • 
+ * 
      
+ *
+ * Besides these few cases, you should use {@link guide/component Components} or
+ * {@link guide/controller Controllers} rather than `ngInit` to initialize values on a scope.
+ * 
      
+ *
+ * 
      
+ * **Note**: If you have assignment in `ngInit` along with a {@link ng.$filter `filter`}, make
+ * sure you have parentheses to ensure correct operator precedence:
+ * 
      + * `
      `
+ * 
      
+ * 
      
+ *
  * @example
-   
-     
-    
      
-      {{greeting}} {{person}}!
-    
      
-

 /**
  * @ngdoc directive
- * @name ng.directive:ngNonBindable
- * @priority 1000
+ * @name ngList
+ * @restrict A
+ * @priority 100
+ *
+ * @param {string=} ngList optional delimiter that should be used to split the value.
  *
  * @description
- * Sometimes it is necessary to write code which looks like bindings but which should be left alone
- * by angular. Use `ngNonBindable` to make angular ignore a chunk of HTML.
+ * Text input that converts between a delimited string and an array of strings. The default
+ * delimiter is a comma followed by a space - equivalent to `ng-list=", "`. You can specify a custom
+ * delimiter as the value of the `ngList` attribute - for example, `ng-list=" | "`.
  *
- * @element ANY
+ * The behaviour of the directive is affected by the use of the `ngTrim` attribute.
+ * * If `ngTrim` is set to `"false"` then whitespace around both the separator and each
+ *   list item is respected. This implies that the user of the directive is responsible for
+ *   dealing with whitespace but also allows you to use whitespace as a delimiter, such as a
+ *   tab or newline character.
+ * * Otherwise whitespace around the delimiter is ignored when splitting (although it is respected
+ *   when joining the list items back together) and whitespace around each list item is stripped
+ *   before it is added to the model.
  *
  * @example
- * In this example there are two location where a simple binding (`{{}}`) is present, but the one
- * wrapped in `ngNonBindable` is left alone.

+/**
+ * @ngdoc type
+ * @name ngModel.NgModelController
+ * @property {*} $viewValue The actual value from the control's view. For `input` elements, this is a
+ * String. See {@link ngModel.NgModelController#$setViewValue} for information about when the $viewValue
+ * is set.
+ *
+ * @property {*} $modelValue The value in the model that the control is bound to.
+ *
+ * @property {Array.} $parsers Array of functions to execute, as a pipeline, whenever
+ *  the control updates the ngModelController with a new {@link ngModel.NgModelController#$viewValue
+    `$viewValue`} from the DOM, usually via user input.
+    See {@link ngModel.NgModelController#$setViewValue `$setViewValue()`} for a detailed lifecycle explanation.
+    Note that the `$parsers` are not called when the bound ngModel expression changes programmatically.
+
+  The functions are called in array order, each passing
+    its return value through to the next. The last return value is forwarded to the
+    {@link ngModel.NgModelController#$validators `$validators`} collection.
+
+  Parsers are used to sanitize / convert the {@link ngModel.NgModelController#$viewValue
+    `$viewValue`}.
+
+  Returning `undefined` from a parser means a parse error occurred. In that case,
+    no {@link ngModel.NgModelController#$validators `$validators`} will run and the `ngModel`
+    will be set to `undefined` unless {@link ngModelOptions `ngModelOptions.allowInvalid`}
+    is set to `true`. The parse error is stored in `ngModel.$error.parse`.
+
+  This simple example shows a parser that would convert text input value to lowercase:
+ * ```js
+ * function parse(value) {
+ *   if (value) {
+ *     return value.toLowerCase();
+ *   }
+ * }
+ * ngModelController.$parsers.push(parse);
+ * ```
+
+ *
+ * @property {Array.} $formatters Array of functions to execute, as a pipeline, whenever
+    the bound ngModel expression changes programmatically. The `$formatters` are not called when the
+    value of the control is changed by user interaction.
+
+  Formatters are used to format / convert the {@link ngModel.NgModelController#$modelValue
+    `$modelValue`} for display in the control.
+
+  The functions are called in reverse array order, each passing the value through to the
+    next. The last return value is used as the actual DOM value.
+
+  This simple example shows a formatter that would convert the model value to uppercase:
+
+ * ```js
+ * function format(value) {
+ *   if (value) {
+ *     return value.toUpperCase();
+ *   }
+ * }
+ * ngModel.$formatters.push(format);
+ * ```
+ *
+ * @property {Object.} $validators A collection of validators that are applied
+ *      whenever the model value changes. The key value within the object refers to the name of the
+ *      validator while the function refers to the validation operation. The validation operation is
+ *      provided with the model value as an argument and must return a true or false value depending
+ *      on the response of that validation.
+ *
+ * ```js
+ * ngModel.$validators.validCharacters = function(modelValue, viewValue) {
+ *   var value = modelValue || viewValue;
+ *   return /[0-9]+/.test(value) &&
+ *          /[a-z]+/.test(value) &&
+ *          /[A-Z]+/.test(value) &&
+ *          /\W+/.test(value);
+ * };
+ * ```
+ *
+ * @property {Object.} $asyncValidators A collection of validations that are expected to
+ *      perform an asynchronous validation (e.g. a HTTP request). The validation function that is provided
+ *      is expected to return a promise when it is run during the model validation process. Once the promise
+ *      is delivered then the validation status will be set to true when fulfilled and false when rejected.
+ *      When the asynchronous validators are triggered, each of the validators will run in parallel and the model
+ *      value will only be updated once all validators have been fulfilled. As long as an asynchronous validator
+ *      is unfulfilled, its key will be added to the controllers `$pending` property. Also, all asynchronous validators
+ *      will only run once all synchronous validators have passed.
+ *
+ * Please note that if $http is used then it is important that the server returns a success HTTP response code
+ * in order to fulfill the validation and a status level of `4xx` in order to reject the validation.
+ *
+ * ```js
+ * ngModel.$asyncValidators.uniqueUsername = function(modelValue, viewValue) {
+ *   var value = modelValue || viewValue;
+ *
+ *   // Lookup user by username
+ *   return $http.get('/api/users/' + value).
+ *      then(function resolved() {

+ * @property {Array.} $viewChangeListeners Array of functions to execute whenever
+ *     a change to {@link ngModel.NgModelController#$viewValue `$viewValue`} has caused a change
+ *     to {@link ngModel.NgModelController#$modelValue `$modelValue`}.
+ *     It is called with no arguments, and its return value is ignored.
+ *     This can be used in place of additional $watches against the model value.
+ *
+ * @property {Object} $error An object hash with all failing validator ids as keys.
+ * @property {Object} $pending An object hash with all pending validator ids as keys.
+ *
+ * @property {boolean} $untouched True if control has not lost focus yet.

+ * `NgModelController` provides API for the {@link ngModel `ngModel`} directive.
+ * The controller contains services for data-binding, validation, CSS updates, and value formatting
+ * and parsing. It purposefully does not contain any logic which deals with DOM rendering or
+ * listening to DOM events.
+ * Such DOM related logic should be provided by other directives which make use of
+ * `NgModelController` for data-binding to control elements.
+ * AngularJS provides this DOM logic for most {@link input `input`} elements.
+ * At the end of this page you can find a {@link ngModel.NgModelController#custom-control-example
+ * custom control example} that uses `ngModelController` to bind to `contenteditable` elements.
+ *
+ * @example
+ * ### Custom Control Example
+ * This example shows how to use `NgModelController` with a custom control to achieve
+ * data-binding. Notice how different directives (`contenteditable`, `ng-model`, and `required`)
+ * collaborate together to achieve the desired result.
+ *
+ * `contenteditable` is an HTML5 attribute, which tells the browser to let the element
+ * contents be edited in place by the user.
+ *
+ * We are using the {@link ng.service:$sce $sce} service here and include the {@link ngSanitize $sanitize}
+ * module to automatically remove "bad" content like inline event listener (e.g. ``).
+ * However, as we are using `$sce` the model can still decide to provide unsafe content if it marks
+ * that content using the `$sce` service.
+ *
+ * 
+    
+      [contenteditable] {
+        border: 1px solid black;
+        background-color: white;
+        min-height: 20px;
+      }
+
+      .ng-invalid {
+        border: 1px solid red;
+      }
+
+    
+    
+      angular.module('customControl', ['ngSanitize']).
+        directive('contenteditable', ['$sce', function($sce) {
+          return {
+            restrict: 'A', // only activate on element attribute

+   * which may be caused by a pending debounced event or because the input is waiting for some
+   * future event.
+   *
+   * If you have an input that uses `ng-model-options` to set up debounced updates or updates that
+   * depend on special events such as `blur`, there can be a period when the `$viewValue` is out of
+   * sync with the ngModel's `$modelValue`.
+   *
+   * In this case, you can use `$rollbackViewValue()` to manually cancel the debounced / future update
+   * and reset the input to the last committed view value.
+   *
+   * It is also possible that you run into difficulties if you try to update the ngModel's `$modelValue`
+   * programmatically before these debounced/future events have resolved/occurred, because AngularJS's
+   * dirty checking mechanism is not able to tell whether the model has actually changed or not.
+   *
+   * The `$rollbackViewValue()` method should be called before programmatically changing the model of an
+   * input which may have such events pending. This is important in order to make sure that the
+   * input field will be updated with the new model value and any pending operations are cancelled.
+   *
+   * @example
+   * 
+   *   
+   *     angular.module('cancel-update-example', [])
+   *
+   *     .controller('CancelUpdateController', ['$scope', function($scope) {
+   *       $scope.model = {value1: '', value2: ''};
+   *
+   *       $scope.setEmpty = function(e, value, rollback) {
+   *         if (e.keyCode === 27) {
+   *           e.preventDefault();
+   *           if (rollback) {
+   *             $scope.myForm[value].$rollbackViewValue();
+   *           }
+   *           $scope.model[value] = '';
+   *         }
+   *       };
+   *     }]);
+   *   
+   *   
+   *     
      
+   *       
      Both of these inputs are only updated if they are blurred. Hitting escape should
+   *       empty them. Follow these steps and observe the difference:
      
+   *       
        
+   *         
      1. Type something in the input. You will see that the model is not yet updated
        2. 
+   *         
      2. Press the Escape key.
+   *           
          
+   *             
        1.  In the first example, nothing happens, because the model is already '', and no
+   *             update is detected. If you blur the input, the model will be set to the current view.
+   *             
          2. 
+   *             
        2.  In the second example, the pending update is cancelled, and the input is set back
+   *             to the last committed view value (''). Blurring the input does nothing.
+   *             
          3. 
+   *           
        
+   *

+   * @name ngModel.NgModelController#$setViewValue
+   *
+   * @description
+   * Update the view value.
+   *
+   * This method should be called when a control wants to change the view value; typically,
+   * this is done from within a DOM event handler. For example, the {@link ng.directive:input input}
+   * directive calls it when the value of the input changes and {@link ng.directive:select select}
+   * calls it when an option is selected.
+   *
+   * When `$setViewValue` is called, the new `value` will be staged for committing through the `$parsers`
+   * and `$validators` pipelines. If there are no special {@link ngModelOptions} specified then the staged
+   * value is sent directly for processing through the `$parsers` pipeline. After this, the `$validators` and
+   * `$asyncValidators` are called and the value is applied to `$modelValue`.
+   * Finally, the value is set to the **expression** specified in the `ng-model` attribute and
+   * all the registered change listeners, in the `$viewChangeListeners` list are called.
+   *
+   * In case the {@link ng.directive:ngModelOptions ngModelOptions} directive is used with `updateOn`
+   * and the `default` trigger is not listed, all those actions will remain pending until one of the
+   * `updateOn` events is triggered on the DOM element.
+   * All these actions will be debounced if the {@link ng.directive:ngModelOptions ngModelOptions}
+   * directive is used with a custom debounce for this particular event.
+   * Note that a `$digest` is only triggered once the `updateOn` events are fired, or if `debounce`
+   * is specified, once the timer runs out.
+   *
+   * When used with standard inputs, the view value will always be a string (which is in some cases
+   * parsed into another type, such as a `Date` object for `input[date]`.)
+   * However, custom controls might also pass objects to this method. In this case, we should make
+   * a copy of the object before passing it to `$setViewValue`. This is because `ngModel` does not
+   * perform a deep watch of objects, it only looks for a change of identity. If you only change
+   * the property of the object then ngModel will not realize that the object has changed and
+   * will not invoke the `$parsers` and `$validators` pipelines. For this reason, you should
+   * not change properties of the copy once it has been passed to `$setViewValue`.
+   * Otherwise you may cause the model value on the scope to change incorrectly.
+   *
+   * 
      
+   * In any case, the value passed to the method should always reflect the current value
+   * of the control. For example, if you are calling `$setViewValue` for an input element,
+   * you should pass the input DOM value. Otherwise, the control and the scope model become
+   * out of sync. It's also important to note that `$setViewValue` does not call `$render` or change
+   * the control's DOM value in any way. If we want to change the control's DOM value
+   * programmatically, we should update the `ngModel` scope expression. Its new value will be
+   * picked up by the model controller, which will run it through the `$formatters`, `$render` it
+   * to update the DOM, and finally call `$validate` on it.

+   * The widget can then call `ctrl.$processModelValue()` to run the model -> view

+ * @param {expression} ngModel assignable {@link guide/expression Expression} to bind to.
+ *
+ * @description
+ * The `ngModel` directive binds an `input`,`select`, `textarea` (or custom form control) to a
+ * property on the scope using {@link ngModel.NgModelController NgModelController},
+ * which is created and exposed by this directive.
+ *
+ * `ngModel` is responsible for:
+ *
+ * - Binding the view into the model, which other directives such as `input`, `textarea` or `select`
+ *   require.
+ * - Providing validation behavior (i.e. required, number, email, url).
+ * - Keeping the state of the control (valid/invalid, dirty/pristine, touched/untouched, validation errors).
+ * - Setting related css classes on the element (`ng-valid`, `ng-invalid`, `ng-dirty`, `ng-pristine`, `ng-touched`,
+ *   `ng-untouched`, `ng-empty`, `ng-not-empty`) including animations.
+ * - Registering the control with its parent {@link ng.directive:form form}.
+ *
+ * Note: `ngModel` will try to bind to the property given by evaluating the expression on the
+ * current scope. If the property doesn't already exist on this scope, it will be created
+ * implicitly and added to the scope.
+ *
+ * For best practices on using `ngModel`, see:
+ *
+ *  - [Understanding Scopes](https://github.com/angular/angular.js/wiki/Understanding-Scopes)
+ *
+ * For basic examples, how to use `ngModel`, see:
+ *
+ *  - {@link ng.directive:input input}
+ *    - {@link input[text] text}
+ *    - {@link input[checkbox] checkbox}
+ *    - {@link input[radio] radio}
+ *    - {@link input[number] number}
+ *    - {@link input[email] email}
+ *    - {@link input[url] url}
+ *    - {@link input[date] date}
+ *    - {@link input[datetime-local] datetime-local}
+ *    - {@link input[time] time}
+ *    - {@link input[month] month}
+ *    - {@link input[week] week}
+ *  - {@link ng.directive:select select}
+ *  - {@link ng.directive:textarea textarea}
+ *
+ * ## Complex Models (objects or collections)
+ *
+ * By default, `ngModel` watches the model by reference, not value. This is important to know when
+ * binding inputs to models that are objects (e.g. `Date`) or collections (e.g. arrays). If only properties of the
+ * object or collection change, `ngModel` will not be notified and so the input will not be  re-rendered.
+ *
+ * The model must be assigned an entirely new object or collection before a re-rendering will occur.
+ *
+ * Some directives have options that will cause them to use a custom `$watchCollection` on the model expression
+ * - for example, `ngOptions` will do so when a `track by` clause is included in the comprehension expression or
+ * if the select is given the `multiple` attribute.
+ *
+ * The `$watchCollection()` method only does a shallow comparison, meaning that changing properties deeper than the
+ * first level of the object (or only changing the properties of an item in the collection if it's an array) will still
+ * not trigger a re-rendering of the model.
+ *
+ * ## CSS classes
+ * The following CSS classes are added and removed on the associated input/select/textarea element
+ * depending on the validity of the model.
+ *
+ *  - `ng-valid`: the model is valid
+ *  - `ng-invalid`: the model is invalid
+ *  - `ng-valid-[key]`: for each valid key added by `$setValidity`
+ *  - `ng-invalid-[key]`: for each invalid key added by `$setValidity`
+ *  - `ng-pristine`: the control hasn't been interacted with yet
+ *  - `ng-dirty`: the control has been interacted with
+ *  - `ng-touched`: the control has been blurred
+ *  - `ng-untouched`: the control hasn't been blurred
+ *  - `ng-pending`: any `$asyncValidators` are unfulfilled
+ *  - `ng-empty`: the view does not contain a value or the value is deemed "empty", as defined
+ *     by the {@link ngModel.NgModelController#$isEmpty} method
+ *  - `ng-not-empty`: the view contains a non-empty value
+ *
+ * Keep in mind that ngAnimate can detect each of these classes when added and removed.
+ *
+ * @animations
+ * Animations within models are triggered when any of the associated CSS classes are added and removed
+ * on the input element which is attached to the model. These classes include: `.ng-pristine`, `.ng-dirty`,
+ * `.ng-invalid` and `.ng-valid` as well as any other validations that are performed on the model itself.
+ * The animations that are triggered within ngModel are similar to how they work in ngClass and
+ * animations can be hooked into using CSS transitions, keyframes as well as JS animations.
+ *
+ * The following example shows a simple way to utilize CSS transitions to style an input element
+ * that has been rendered as invalid after it has been validated:
+ *
+ * 
      + * //be sure to include ngAnimate as a module to hook into more
+ * //advanced animations
+ * .my-input {
+ *   transition:0.5s linear all;
+ *   background: white;
+ * }
+ * .my-input.ng-invalid {
+ *   background: red;
+ *   color:white;
+ * }
+ * 
      
+ *
+ * @example
+ * ### Basic Usage
+ * 
+     
+       
+       
+       
      
+        Update input to see transitions when valid/invalid.
+        Integer is a valid value.
+       
      
+       
      
+         
+       
      
+           
+ *       
+ *
+ * @example
+ * ### Binding to a getter/setter
+ *
+ * Sometimes it's helpful to bind `ngModel` to a getter/setter function.  A getter/setter is a
+ * function that returns a representation of the model when called with zero arguments, and sets
+ * the internal state of a model when called with an argument. It's sometimes useful to use this
+ * for models that have an internal representation that's different from what the model exposes
+ * to the view.
+ *
+ * 
      
+ * **Best Practice:** It's best to keep getters fast because AngularJS is likely to call them more
+ * frequently than other parts of your code.
+ * 
      
+ *
+ * You use this behavior by adding `ng-model-options="{ getterSetter: true }"` to an element that
+ * has `ng-model` attached to it. You can also add `ng-model-options="{ getterSetter: true }"` to
+ * a `
      `, which will enable this behavior for all ``s within it. See
+ * {@link ng.directive:ngModelOptions `ngModelOptions`} for more.

+ *

+ *

+

      user.name =

+             name: function(newName) {
+              // Note that newName can be undefined for two reasons:
+              // 1. Because it is called as a getter and thus called with no arguments
+              // 2. Because the property should actually be set to undefined. This happens e.g. if the
+              //    input is invalid
+              return arguments.length ? (_name = newName) : _name;
+             }

+/**
+ * @ngdoc directive
+ * @name ngModelOptions
+ * @restrict A
+ * @priority 10
+ *
+ * @description
+ * This directive allows you to modify the behaviour of {@link ngModel} directives within your
+ * application. You can specify an `ngModelOptions` directive on any element. All {@link ngModel}
+ * directives will use the options of their nearest `ngModelOptions` ancestor.
+ *
+ * The `ngModelOptions` settings are found by evaluating the value of the attribute directive as
+ * an AngularJS expression. This expression should evaluate to an object, whose properties contain
+ * the settings. For example: `
      
+ *   
      
+ *     
+ *   
      
+ * 
      
+ * ```
+ *
+ * the `input` element will have the following settings
+ *
+ * ```js
+ * { allowInvalid: true, updateOn: 'default', debounce: 0 }
+ * ```
+ *
+ * Notice that the `debounce` setting was not inherited and used the default value instead.
+ *
+ * You can specify that all undefined settings are automatically inherited from an ancestor by
+ * including a property with key of `"*"` and value of `"$inherit"`.
+ *
+ * For example given the following fragment of HTML
+ *
+ *
+ * ```html
+ * 
      
+ *   
      
+ *     
+ *   
      
+ * 
      
+ * ```
+ *
+ * the `input` element will have the following settings
+ *
+ * ```js
+ * { allowInvalid: true, updateOn: 'default', debounce: 200 }
+ * ```
+ *
+ * Notice that the `debounce` setting now inherits the value from the outer `
      ` element.
+ *
+ * If you are creating a reusable component then you should be careful when using `"*": "$inherit"`
+ * since you may inadvertently inherit a setting in the future that changes the behavior of your component.
+ *
+ *
+ * ## Triggering and debouncing model updates
+ *
+ * The `updateOn` and `debounce` properties allow you to specify a custom list of events that will
+ * trigger a model update and/or a debouncing delay so that the actual update only takes place when
+ * a timer expires; this timer will be reset after another change takes place.
+ *
+ * Given the nature of `ngModelOptions`, the value displayed inside input fields in the view might
+ * be different from the value in the actual model. This means that if you update the model you
+ * should also invoke {@link ngModel.NgModelController#$rollbackViewValue} on the relevant input field in
+ * order to make sure it is synchronized with the model and that any debounced action is canceled.
+ *
+ * The easiest way to reference the control's {@link ngModel.NgModelController#$rollbackViewValue}
+ * method is by making sure the input is placed inside a form that has a `name` attribute. This is
+ * important because `form` controllers are published to the related scope under the name in their
+ * `name` attribute.
+ *
+ * Any pending changes will take place immediately when an enclosing form is submitted via the
+ * `submit` event. Note that `ngClick` events will occur before the model is updated. Use `ngSubmit`
+ * to have access to the updated model.
+ *
+ * ### Overriding immediate updates
+ *
+ * The following example shows how to override immediate updates. Changes on the inputs within the
+ * form will update the model only when the control loses focus (blur event). If `escape` key is
+ * pressed while the input field is focused, the value is reset to the value in the current model.
+ *
+ * 
+ *   
+ *     
      
+ *       
      
+ *         
      
+ *         
      
+ *       
      
+ *       
      user.name = 
      
+ *     
      
+ *         
+ *   
+ *     angular.module('optionsExample', [])
+ *       .controller('ExampleController', ['$scope', function($scope) {
+ *         $scope.user = { name: 'say', data: '' };
+ *
+ *         $scope.cancel = function(e) {
+ *           if (e.keyCode === 27) {
+ *             $scope.userForm.userName.$rollbackViewValue();
+ *           }
+ *         };
+ *       }]);
+ *   
+ *   
+ *     var model = element(by.binding('user.name'));
+ *     var input = element(by.model('user.name'));
+ *     var other = element(by.model('user.data'));
+ *
+ *     it('should allow custom events', function() {
+ *       input.sendKeys(' hello');
+ *       input.click();
+ *       expect(model.getText()).toEqual('say');
+ *       other.click();
+ *       expect(model.getText()).toEqual('say hello');
+ *     });
+ *
+ *     it('should $rollbackViewValue when model changes', function() {
+ *       input.sendKeys(' hello');
+ *       expect(input.getAttribute('value')).toEqual('say hello');
+ *       input.sendKeys(protractor.Key.ESCAPE);
+ *       expect(input.getAttribute('value')).toEqual('say');
+ *       other.click();
+ *       expect(model.getText()).toEqual('say');
+ *     });
+ *   
+ *       
+ *
+ * ### Debouncing updates
+ *
+ * The next example shows how to debounce model changes. Model will be updated only 1 sec after last change.
+ * If the `Clear` button is pressed, any debounced action is canceled and the value becomes empty.
+ *
+ * 
+ *   
+ *     
      
+ *       
      
+ *         Name:
+ *         
+ *         
      
+ *       
      
+ *       
      user.name = 
      
+ *     
      
+ *         
+ *   
+ *     angular.module('optionsExample', [])
+ *       .controller('ExampleController', ['$scope', function($scope) {
+ *         $scope.user = { name: 'say' };
+ *       }]);
+ *   
+ *       
+ *
+ * ### Default events, extra triggers, and catch-all debounce values
+ *
+ * This example shows the relationship between "default" update events and
+ * additional `updateOn` triggers.
+ *
+ * `default` events are those that are bound to the control, and when fired, update the `$viewValue`
+ * via {@link ngModel.NgModelController#$setViewValue $setViewValue}. Every event that is not listed
+ * in `updateOn` is considered a "default" event, since different control types have different
+ * default events.
+ *
+ * The control in this example updates by "default", "click", and "blur", with different `debounce`
+ * values. You can see that "click" doesn't have an individual `debounce` value -
+ * therefore it uses the `*` debounce value.
+ *
+ * There is also a button that calls {@link ngModel.NgModelController#$setViewValue $setViewValue}
+ * directly with a "custom" event. Since "custom" is not defined in the `updateOn` list,
+ * it is considered a "default" event and will update the
+ * control if "default" is defined in `updateOn`, and will receive the "default" debounce value.
+ * Note that this is just to illustrate how custom controls would possibly call `$setViewValue`.
+ *
+ * You can change the `updateOn` and `debounce` configuration to test different scenarios. This
+ * is done with {@link ngModel.NgModelController#$overrideModelOptions $overrideModelOptions}.
+ *
+  
+    
+       
+    
+    
+      angular.module('optionsExample', [])
+        .component('modelUpdateDemo', {
+          templateUrl: 'template.html',
+          controller: function() {

+
+            this.options = {
+              updateOn: 'default blur click',
+              debounce: {
+                default: 2000,
+                blur: 0,
+                '*': 1000
+              }
+            };
+
+            this.updateEvents = function() {
+              var eventList = this.options.updateOn.split(' ');
+              eventList.push('*');
+              var events = {};
+
+              for (var i = 0; i < eventList.length; i++) {
+                events[eventList[i]] = this.options.debounce[eventList[i]];
+              }
+
+              this.events = events;
+            };
+
+            this.updateOptions = function() {
+              var options = angular.extend(this.options, {
+                updateOn: Object.keys(this.events).join(' ').replace('*', ''),
+                debounce: this.events
+              });
+
+              this.form.input.$overrideModelOptions(options);
+            };
+
+            // Initialize the event form
+            this.updateEvents();
+          }
+        });

+          
+

+          
+        
      OptionDebounce value
      {{key}}
      
+
+        
      
+        
+      
      
+          
+        
+ *
+ *
+ * ## Model updates and validation
+ *
+ * The default behaviour in `ngModel` is that the model value is set to `undefined` when the
+ * validation determines that the value is invalid. By setting the `allowInvalid` property to true,
+ * the model will still be updated even if the value is invalid.
+ *
+ *
+ * ## Connecting to the scope
+ *
+ * By setting the `getterSetter` property to true you are telling ngModel that the `ngModel` expression
+ * on the scope refers to a "getter/setter" function rather than the value itself.
+ *
+ * The following example shows how to bind to getter/setters:
+ *
+ * 
+ *   
+ *     
      
+ *       
      
+ *         
+ *       
      
+ *       
      user.name = 
      
+ *     
      
+ *         
+ *   
+ *     angular.module('getterSetterExample', [])
+ *       .controller('ExampleController', ['$scope', function($scope) {
+ *         var _name = 'Brian';
+ *         $scope.user = {
+ *           name: function(newName) {
+ *             return angular.isDefined(newName) ? (_name = newName) : _name;
+ *           }
+ *         };
+ *       }]);
+ *   
+ *       
+ *
+ *
+ * ## Programmatically changing options
+ *
+ * The `ngModelOptions` expression is only evaluated once when the directive is linked; it is not
+ * watched for changes. However, it is possible to override the options on a single
+ * {@link ngModel.NgModelController} instance with
+ * {@link ngModel.NgModelController#$overrideModelOptions `NgModelController#$overrideModelOptions()`}.
+ * See also the example for
+ * {@link ngModelOptions#default-events-extra-triggers-and-catch-all-debounce-values
+ * Default events, extra triggers, and catch-all debounce values}.
+ *
+ *
+ * ## Specifying timezones
+ *
+ * You can specify the timezone that date/time input directives expect by providing its name in the
+ * `timezone` property.
+ *
+ *
+ * ## Formatting the value of `time` and `datetime-local`
+ *
+ * With the options `timeSecondsFormat` and `timeStripZeroSeconds` it is possible to adjust the value
+ * that is displayed in the control. Note that browsers may apply their own formatting
+ * in the user interface.
+ *
+   
+     
+       
+     
+     
+        angular.module('timeExample', [])
+          .component('timeExample', {
+            templateUrl: 'timeExample.html',
+            controller: function() {
+              this.time = new Date(1970, 0, 1, 14, 57, 0);
+
+              this.options = {
+                timeSecondsFormat: 'ss',

+         timeSecondsFormat:
+         
+         
      
+         timeStripZeroSeconds:
+         
+        
      
+            
+ *        
+ *
+ * @param {Object} ngModelOptions options to apply to {@link ngModel} directives on this element and
+ *   and its descendents.
+ *
+ * **General options**:
+ *
+ *   - `updateOn`: string specifying which event should the input be bound to. You can set several
+ *     events using an space delimited list. There is a special event called `default` that
+ *     matches the default events belonging to the control. These are the events that are bound to
+ *     the control, and when fired, update the `$viewValue` via `$setViewValue`.
+ *
+ *     `ngModelOptions` considers every event that is not listed in `updateOn` a "default" event,
+ *     since different control types use different default events.
+ *
+ *     See also the section {@link ngModelOptions#triggering-and-debouncing-model-updates
+ *     Triggering and debouncing model updates}.
+ *
+ *   - `debounce`: integer value which contains the debounce model update value in milliseconds. A
+ *     value of 0 triggers an immediate update. If an object is supplied instead, you can specify a
+ *     custom value for each event. For example:
+ *     ```
+ *     ng-model-options="{
+ *       updateOn: 'default blur',
+ *       debounce: { 'default': 500, 'blur': 0 }
+ *     }"
+ *     ```
+ *     You can use the `*` key to specify a debounce value that applies to all events that are not
+ *     specifically listed. In the following example, `mouseup` would have a debounce delay of 1000:
+ *     ```
+ *     ng-model-options="{
+ *       updateOn: 'default blur mouseup',
+ *       debounce: { 'default': 500, 'blur': 0, '*': 1000 }
+ *     }"
+ *     ```
+ *   - `allowInvalid`: boolean value which indicates that the model can be set with values that did
+ *     not validate correctly instead of the default behavior of setting the model to undefined.
+ *   - `getterSetter`: boolean value which determines whether or not to treat functions bound to
+ *     `ngModel` as getters/setters.
+ *
+ *
+ *  **Input-type specific options**:
+ *
+ *   - `timezone`: Defines the timezone to be used to read/write the `Date` instance in the model for
+ *     ``, ``, ... . It understands UTC/GMT and the
+ *     continental US time zone abbreviations, but for general use, use a time zone offset, for
+ *     example, `'+0430'` (4 hours, 30 minutes east of the Greenwich meridian)
+ *     If not specified, the timezone of the browser will be used.
+ *     Note that changing the timezone will have no effect on the current date, and is only applied after
+ *     the next input / model change.
+ *
+ *   - `timeSecondsFormat`: Defines if the `time` and `datetime-local` types should show seconds and
+ *     milliseconds. The option follows the format string of {@link date date filter}.
+ *     By default, the options is `undefined` which is equal to `'ss.sss'` (seconds and milliseconds).
+ *     The other options are `'ss'` (strips milliseconds), and `''` (empty string), which strips both
+ *     seconds and milliseconds.
+ *     Note that browsers that support `time` and `datetime-local` require the hour and minutes
+ *     part of the time string, and may show the value differently in the user interface.
+ *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.
+ *
+ *   - `timeStripZeroSeconds`: Defines if the `time` and `datetime-local` types should strip the
+ *     seconds and milliseconds from the formatted value if they are zero. This option is applied
+ *     after `timeSecondsFormat`.
+ *     This option can be used to make the formatting consistent over different browsers, as some
+ *     browsers with support for `time` will natively hide the milliseconds and
+ *     seconds if they are zero, but others won't, and browsers that don't implement these input
+ *     types will always show the full string.
+ *     {@link ngModelOptions#formatting-the-value-of-time-and-datetime-local- See the example}.

+ * ### Simple `select` elements with static options
+ *
+ * 
+ * 
+ * 

+ *   

+ *     

+ *     

+ *
+ *     

+ *     

+ *     

+ *     singleSelect = {{data.singleSelect}}
+ *
+ *     

+ *     

+ *     

+ *     multipleSelect = {{data.multipleSelect}}

+ *   

+ * 

+ * 
+ * 
+ *  angular.module('staticSelect', [])
+ *    .controller('ExampleController', ['$scope', function($scope) {
+ *      $scope.data = {
+ *       singleSelect: null,
+ *       multipleSelect: [],
+ *       option1: 'option-1'
+ *      };
+ *
+ *      $scope.forceUnknownOption = function() {
+ *        $scope.data.singleSelect = 'nonsense';
+ *      };
+ *   }]);
+ * 
+ *
+ *
+ * @example
+ * ### Using `ngRepeat` to generate `select` options
+ * 
+ * 
+ * 

+ *   

+ *     
+ *     
+ *   

+ *   

+ *   model = {{data.model}}

+ * 

+ * 
+ * 
+ *  angular.module('ngrepeatSelect', [])
+ *    .controller('ExampleController', ['$scope', function($scope) {
+ *      $scope.data = {
+ *       model: null,
+ *       availableOptions: [
+ *         {id: '1', name: 'Option A'},
+ *         {id: '2', name: 'Option B'},
+ *         {id: '3', name: 'Option C'}
+ *       ]
+ *      };
+ *   }]);
+ * 
+ *
+ *
+ * @example
+ * ### Using `ngValue` to bind the model to an array of objects
+ * 
+ * 
+ * 

+ *   

+ *     
+ *     
+ *   

+ *   

+ *   
model = {{data.model | json}}


+ * 

+ * 
+ * 
+ *  angular.module('ngvalueSelect', [])

+           {value: {prop: 'value'}, name: 'object'},
+           {value: ['a'], name: 'array'}
+ *       ]
+ *      };
+ *   }]);
+ * 
+ *
+ *
+ * @example
+ * ### Using `select` with `ngOptions` and setting a default value
+ * See the {@link ngOptions ngOptions documentation} for more `ngOptions` usage examples.
+ *
+ * 
+ * 
+ * 

+ *   

+ *     
+ *     
+ *   

+ *   

+ *   option = {{data.selectedOption}}

+ * 

+ * 
+ * 
+ *  angular.module('defaultValueSelect', [])
+ *    .controller('ExampleController', ['$scope', function($scope) {
+ *      $scope.data = {
+ *       availableOptions: [
+ *         {id: '1', name: 'Option A'},
+ *         {id: '2', name: 'Option B'},
+ *         {id: '3', name: 'Option C'}
+ *       ],
+ *       selectedOption: {id: '3', name: 'Option C'} //This sets the default value of the select in the ui
+ *       };
+ *   }]);
+ * 
+ *
+ *
+ * @example
+ * ### Binding `select` to a non-string value via `ngModel` parsing / formatting
+ *
+ * 
+ *   
+ *     
+ *     {{ model }}
+ *   
+ *   
+ *     angular.module('nonStringSelect', [])
+ *       .run(function($rootScope) {
+ *         $rootScope.model = { id: 2 };
+ *       })
+ *       .directive('convertToNumber', function() {
+ *         return {

+ *           link: function(scope, element, attrs, ngModel) {
+ *             ngModel.$parsers.push(function(val) {
+ *               return parseInt(val, 10);
+ *             });
+ *             ngModel.$formatters.push(function(val) {
+ *               return '' + val;
+ *             });
+ *           }
+ *         };
+ *       });
+ *   
+ *   
+ *     it('should initialize to model', function() {
+ *       expect(element(by.model('model.id')).$('option:checked').getText()).toEqual('Two');

+/**
+ * @ngdoc directive
+ * @name ngPattern
+ * @restrict A
+ *
+ * @param {expression|RegExp} ngPattern AngularJS expression that must evaluate to a `RegExp` or a `String`
+ *                                      parsable into a `RegExp`, or a `RegExp` literal. See above for
+ *                                      more details.
+ *
+ * @description
+ *
+ * ngPattern adds the pattern {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
+ * It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.
+ *
+ * The validator sets the `pattern` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
+ * does not match a RegExp which is obtained from the `ngPattern` attribute value:
+ * - the value is an AngularJS expression:
+ *   - If the expression evaluates to a RegExp object, then this is used directly.
+ *   - If the expression evaluates to a string, then it will be converted to a RegExp after wrapping it
+ *     in `^` and `$` characters. For instance, `"abc"` will be converted to `new RegExp('^abc$')`.
+ * - If the value is a RegExp literal, e.g. `ngPattern="/^\d+$/"`, it is used directly.
+ *
+ * 

+ * **Note:** Avoid using the `g` flag on the RegExp, as it will cause each successive search to
+ * start at the index of the last search's match, thus not taking the whole input value into
+ * account.
+ * 

+ *
+ * 

+ * **Note:** This directive is also added when the plain `pattern` attribute is used, with two
+ * differences:
+ * 
    
+ *   
  1. 
+ *     `ngPattern` does not set the `pattern` attribute and therefore HTML5 constraint validation is
+ *     not available.
+ *   
    2. 
+ *   
  2. 
+ *     The `ngPattern` attribute must be an expression, while the `pattern` value must be
+ *     interpolated.
+ *   
    3. 
+ * 

+ * 

+ *
+ * @example
+ * 
+ *   
+ *     
+ *     

+ *       

+ *

+ *
+ * @description
+ *
+ * ngMaxlength adds the maxlength {@link ngModel.NgModelController#$validators `validator`} to {@link ngModel `ngModel`}.
+ * It is most often used for text-based {@link input `input`} controls, but can also be applied to custom text-based controls.
+ *
+ * The validator sets the `maxlength` error key if the {@link ngModel.NgModelController#$viewValue `ngModel.$viewValue`}
+ * is longer than the integer obtained by evaluating the AngularJS expression given in the
+ * `ngMaxlength` attribute value.
+ *
+ * 

+ * **Note:** This directive is also added when the plain `maxlength` attribute is used, with two
+ * differences:
+ * 
    
+ *   
  1. 
+ *     `ngMaxlength` does not set the `maxlength` attribute and therefore HTML5 constraint
+ *     validation is not available.
+ *   
    2.

  2. 
+ *     The `ngMaxlength` attribute must be an expression, while the `maxlength` value must be
+ *     interpolated.
