Class YAHOO.ext.Element

Package:YAHOO.ext
Class:Element
Extends:Object
Subclasses:Actor
Defined In:Element.js
Wraps around a DOM element and provides convenient access to Yahoo UI library functionality (and more).

Usage:
var el = YAHOO.ext.Element.get('myElementId');
// or the shorter
var el = getEl('myElementId');
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.

For working with collections of Elements, see YAHOO.ext.CompositeElement
