/**
|
|
* @class YAHOO.ext.Element
|
|
* Wraps around a DOM element and provides convenient access to Yahoo
|
|
* UI library functionality (and more).<br><br>
|
|
* Usage:<br>
|
|
* <pre><code>
|
|
* var el = YAHOO.ext.Element.get('myElementId');
|
|
* // or the shorter
|
|
* var el = getEl('myElementId');
|
|
* </code></pre>
|
|
* Using YAHOO.ext.Element.get() instead of calling the constructor directly ensures you get the same object
|
|
* each call instead of constructing a new one.<br><br>
|
|
* For working with collections of Elements, see <a href="YAHOO.ext.CompositeElement.html">YAHOO.ext.CompositeElement</a>
|
|
* @requires YAHOO.util.Dom
|
|

* @requires YAHOO.util.Anim (optional) to support animation
|
|
* @requires YAHOO.util.Motion (optional) to support animation
|
|
* @requires YAHOO.util.Easing (optional) to support animation
|
|
* @constructor Create a new Element directly.
|
|
* @param {String/HTMLElement} element
|
|
* @param {<i>Boolean</i>} forceNew (optional) 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).
