</span></span> * @class Ext.dom.Element
 * @alternateClassName Ext.Element
 * @alternateClassName Ext.core.Element
 * @extend Ext.dom.AbstractElement
 *
 * Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.
 *
 * All instances of this class inherit the methods of {@link Ext.fx.Anim} making visual effects easily available to all
 * DOM elements.
 *
 * Note that the events documented in this class are not Ext events, they encapsulate browser events. Some older browsers
 * may not support the full range of events. Which events are supported is beyond the control of Ext JS.
 *
 * Usage:
 *
 *     // by id
 *     var el = Ext.get(&quot;my-div&quot;);
 *
 *     // by DOM element reference
 *     var el = Ext.get(myDivElement);
 *
 * # Animations
 *
 * When an element is manipulated, by default there is no animation.
 *
 *     var el = Ext.get(&quot;my-div&quot;);
 *
 *     // no animation
 *     el.setWidth(100);
 *
 * Many of the functions for manipulating an element have an optional &quot;animate&quot; parameter. This parameter can be
 * specified as boolean (true) for default animation effects.
 *
 *     // default animation
 *     el.setWidth(100, true);
 *
 * To configure the effects, an object literal with animation options to use as the Element animation configuration
 * object can also be specified. Note that the supported Element animation configuration options are a subset of the
 * {@link Ext.fx.Anim} animation options specific to Fx effects. The supported Element animation configuration options
 * are:
 *
 *     Option    Default   Description
 *     --------- --------  ---------------------------------------------
 *     {@link Ext.fx.Anim#duration duration}  350       The duration of the animation in milliseconds
 *     {@link Ext.fx.Anim#easing easing}    easeOut   The easing method
 *     {@link Ext.fx.Anim#callback callback}  none      A function to execute when the anim completes
 *     {@link Ext.fx.Anim#scope scope}     this      The scope (this) of the callback function
 *
 * Usage:
 *
 *     // Element animation options object
 *     var opt = {
 *         {@link Ext.fx.Anim#duration duration}: 1000,
 *         {@link Ext.fx.Anim#easing easing}: 'elasticIn',
 *         {@link Ext.fx.Anim#callback callback}: this.foo,
 *         {@link Ext.fx.Anim#scope scope}: this
 *     };
 *     // animation with some options set
 *     el.setWidth(100, opt);
 *
 * The Element animation object being used for the animation will be set on the options object as &quot;anim&quot;, which allows
 * you to stop or manipulate the animation. Here is an example:
 *
 *     // using the &quot;anim&quot; property to get the Anim object
 *     if(opt.anim.isAnimated()){
 *         opt.anim.stop();
 *     }
 *
 * # Composite (Collections of) Elements
 *
 * For working with collections of Elements, see {@link Ext.CompositeElement}
 *
 * @constructor
 * Creates new Element directly.
 * @param {String/HTMLElement} element
 * @param {Boolean} [forceNew] By default the constructor checks to see if there is already an instance of this
 * element in the cache and if there is it returns the same instance. This will skip that check (useful for extending
 * this class).
 * @return {Object}

     *
     * @param {String} eventName The name of event to handle.
     *
     * @param {Function} fn The handler function the event invokes. This function is passed the following parameters:
     *
     * - **evt** : EventObject
     *
     *   The {@link Ext.EventObject EventObject} describing the event.
     *
     * - **el** : HtmlElement
     *
     *   The DOM element which was the target of the event. Note that this may be filtered by using the delegate option.
     *
     * - **o** : Object
     *
     *   The options object from the call that setup the listener.
     *
     * @param {Object} scope (optional) The scope (**this** reference) in which the handler function is executed. **If
     * omitted, defaults to this Element.**
     *
     * @param {Object} options (optional) An object containing handler configuration properties. This may contain any of
     * the following properties:
     *
     * - **scope** Object :
     *
     *   The scope (**this** reference) in which the handler function is executed. **If omitted, defaults to this
     *   Element.**
     *
     * - **delegate** String:
     *
     *   A simple selector to filter the target or look for a descendant of the target. See below for additional details.
     *
     * - **stopEvent** Boolean:
     *
     *   True to stop the event. That is stop propagation, and prevent the default action.
     *
     * - **preventDefault** Boolean:
     *
     *   True to prevent the default action
     *
     * - **stopPropagation** Boolean:
     *
     *   True to prevent event propagation
     *
     * - **normalized** Boolean:
     *
     *   False to pass a browser event to the handler function instead of an Ext.EventObject
     *
     * - **target** Ext.dom.Element:
     *
     *   Only call the handler if the event was fired on the target Element, _not_ if the event was bubbled up from a
     *   child node.
     *
     * - **delay** Number:
     *
     *   The number of milliseconds to delay the invocation of the handler after the event fires.
     *
     * - **single** Boolean:
     *
     *   True to add a handler to handle just the next firing of the event, and then remove itself.
     *
     * - **buffer** Number:
     *
     *   Causes the handler to be scheduled to run in an {@link Ext.util.DelayedTask} delayed by the specified number of
     *   milliseconds. If the event fires again within that time, the original handler is _not_ invoked, but the new
     *   handler is scheduled in its place.
     *
     * **Combining Options**
     *
     * Using the options argument, it is possible to combine different types of listeners:
     *
     * A delayed, one-time listener that auto stops the event and adds a custom argument (forumId) to the options
     * object. The options object is available as the third parameter in the handler function.
     *
     * Code:
     *
     *     el.on('click', this.onClick, this, {
     *         single: true,
     *         delay: 100,
     *         stopEvent : true,
     *         forumId: 4
     *     });
     *
     * **Attaching multiple handlers in 1 call**
     *
     * The method also allows for a single argument to be passed which is a config object containing properties which
     * specify multiple handlers.
     *
     * Code:
     *
     *     el.on({
     *         'click' : {
     *             fn: this.onClick,
     *             scope: this,
     *             delay: 100
     *         },
     *         'mouseover' : {
     *             fn: this.onMouseOver,
     *             scope: this
     *         },
     *         'mouseout' : {
     *             fn: this.onMouseOut,
     *             scope: this
     *         }
     *     });
     *
     * Or a shorthand syntax:
     *
     * Code:
     *
     *     el.on({
     *         'click' : this.onClick,
     *         'mouseover' : this.onMouseOver,
     *         'mouseout' : this.onMouseOut,
     *         scope: this
     *     });
     *
     * **delegate**
     *
     * This is a configuration option that you can pass along when registering a handler for an event to assist with
     * event delegation. Event delegation is a technique that is used to reduce memory consumption and prevent exposure
     * to memory-leaks. By registering an event for a container element as opposed to each element within a container.
     * By setting this configuration option to a simple selector, the target element will be filtered to look for a
     * descendant of the target. For example:
     *
     *     // using this markup:
     *     &lt;div id='elId'&gt;
     *         &lt;p id='p1'&gt;paragraph one&lt;/p&gt;
     *         &lt;p id='p2' class='clickable'&gt;paragraph two&lt;/p&gt;
     *         &lt;p id='p3'&gt;paragraph three&lt;/p&gt;
     *     &lt;/div&gt;
     *
     *     // utilize event delegation to registering just one handler on the container element:
     *     el = Ext.get('elId');
     *     el.on(
     *         'click',
     *         function(e,t) {
     *             // handle click
     *             console.info(t.id); // 'p2'
     *         },
     *         this,
     *         {
     *             // filter the target element to be a descendant with the class 'clickable'
     *             delegate: '.clickable'
     *         }
