* @author Ariel Flesler
|
|
* @version 1.2.8
|
|
*
|
|
* @id jQuery.fn.localScroll
|
|
* @param {Object} settings Hash of settings, it is passed in to jQuery.ScrollTo, none is required.
|
|
* @return {jQuery} Returns the same jQuery object, for chaining.
|
|
*
|
|
* @example $('ul.links').localScroll();
|
|
*
|
|
* @example $('ul.links').localScroll({ filter:'.animated', duration:400, axis:'x' });
|
|
*
|
|
* @example $.localScroll({ target:'#pane', axis:'xy', queue:true, event:'mouseover' });
|
|
*
|
|
* Notes:
|
|
* - The plugin requires jQuery.ScrollTo.
|
|
* - The hash of settings, is passed to jQuery.ScrollTo, so the settings are valid for that plugin as well.
|
|
* - jQuery.localScroll can be used if the desired links, are all over the document, it accepts the same settings.
|
|
* - If the setting 'lazy' is set to true, then the binding will still work for later added anchors.
|
|
* - If onBefore returns false, the event is ignored.
