-/**\r
- * @class Ext.Element\r
- * <p>Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.</p>\r
- * <p>All instances of this class inherit the methods of {@link Ext.Fx} making visual effects easily available to all DOM elements.</p>\r
- * <p>Note that the events documented in this class are not Ext events, they encapsulate browser events. To\r
- * access the underlying browser event, see {@link Ext.EventObject#browserEvent}. Some older\r
- * browsers may not support the full range of events. Which events are supported is beyond the control of ExtJs.</p>\r
- * Usage:<br>\r
-<pre><code>\r
-// by id\r
-var el = Ext.get("my-div");\r
-\r
-// by DOM element reference\r
-var el = Ext.get(myDivElement);\r
-</code></pre>\r
- * <b>Animations</b><br />\r
- * <p>When an element is manipulated, by default there is no animation.</p>\r
- * <pre><code>\r
-var el = Ext.get("my-div");\r
-\r
-// no animation\r
-el.setWidth(100);\r
- * </code></pre>\r
- * <p>Many of the functions for manipulating an element have an optional "animate" parameter. This\r
- * parameter can be specified as boolean (<tt>true</tt>) for default animation effects.</p>\r
- * <pre><code>\r
-// default animation\r
-el.setWidth(100, true);\r
- * </code></pre>\r
- * \r
- * <p>To configure the effects, an object literal with animation options to use as the Element animation\r
- * configuration object can also be specified. Note that the supported Element animation configuration\r
- * options are a subset of the {@link Ext.Fx} animation options specific to Fx effects. The supported\r
- * Element animation configuration options are:</p>\r
-<pre>\r
-Option Default Description\r
---------- -------- ---------------------------------------------\r
-{@link Ext.Fx#duration duration} .35 The duration of the animation in seconds\r
-{@link Ext.Fx#easing easing} easeOut The easing method\r
-{@link Ext.Fx#callback callback} none A function to execute when the anim completes\r
-{@link Ext.Fx#scope scope} this The scope (this) of the callback function\r
-</pre>\r
- * \r
- * <pre><code>\r
-// Element animation options object\r
-var opt = {\r
- {@link Ext.Fx#duration duration}: 1,\r
- {@link Ext.Fx#easing easing}: 'elasticIn',\r
- {@link Ext.Fx#callback callback}: this.foo,\r
- {@link Ext.Fx#scope scope}: this\r
-};\r
-// animation with some options set\r
-el.setWidth(100, opt);\r
- * </code></pre>\r
- * <p>The Element animation object being used for the animation will be set on the options\r
- * object as "anim", which allows you to stop or manipulate the animation. Here is an example:</p>\r
- * <pre><code>\r
-// using the "anim" property to get the Anim object\r
-if(opt.anim.isAnimated()){\r
- opt.anim.stop();\r
-}\r
- * </code></pre>\r
- * <p>Also see the <tt>{@link #animate}</tt> method for another animation technique.</p>\r
- * <p><b> Composite (Collections of) Elements</b></p>\r
- * <p>For working with collections of Elements, see {@link Ext.CompositeElement}</p>\r
- * @constructor Create a new Element directly.\r
- * @param {String/HTMLElement} element\r
- * @param {Boolean} 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).\r

- * options object. The options object is available as the third parameter in the handler function.<div style="margin: 5px 20px 20px;">\r
- * Code:<pre><code>\r
-el.on('click', this.onClick, this, {\r
- single: true,\r
- delay: 100,\r
- stopEvent : true,\r
- forumId: 4\r
-});</code></pre></p>\r
- * <p>\r
- * <b>Attaching multiple handlers in 1 call</b><br>\r
- * The method also allows for a single argument to be passed which is a config object containing properties\r
- * which specify multiple handlers.</p>\r
- * <p>\r

- * <p>This is a configuration option that you can pass along when registering a handler for\r

- * reduce memory consumption and prevent exposure to memory-leaks. By registering an event\r
- * for a container element as opposed to each element within a container. By setting this\r
- * configuration option to a simple selector, the target element will be filtered to look for\r
- * a descendant of the target.\r
- * For example:<pre><code>\r
-// using this markup:\r
-<div id='elId'>\r
- <p id='p1'>paragraph one</p>\r
- <p id='p2' class='clickable'>paragraph two</p>\r
- <p id='p3'>paragraph three</p>\r
-</div>\r
-// utilize event delegation to registering just one handler on the container element: \r
-el = Ext.get('elId');\r
-el.on(\r
- 'click',\r
- function(e,t) {\r
- // handle click\r
- console.info(t.id); // 'p2'\r
- },\r
- this,\r
- {\r
- // filter the target element to be a descendant with the class 'clickable'\r
- delegate: '.clickable' \r

+ * @class Ext.Element
+ * <p>Encapsulates a DOM element, adding simple DOM manipulation facilities, normalizing for browser differences.</p>
+ * <p>All instances of this class inherit the methods of {@link Ext.Fx} making visual effects easily available to all DOM elements.</p>
+ * <p>Note that the events documented in this class are not Ext events, they encapsulate browser events. To
+ * access the underlying browser event, see {@link Ext.EventObject#browserEvent}. Some older
+ * browsers may not support the full range of events. Which events are supported is beyond the control of ExtJs.</p>
+ * Usage:<br>
+<pre><code>
+// by id
+var el = Ext.get("my-div");
+
+// by DOM element reference
+var el = Ext.get(myDivElement);
+</code></pre>
+ * <b>Animations</b><br />
+ * <p>When an element is manipulated, by default there is no animation.</p>
+ * <pre><code>
+var el = Ext.get("my-div");
+
+// no animation
+el.setWidth(100);
+ * </code></pre>
+ * <p>Many of the functions for manipulating an element have an optional "animate" parameter. This
+ * parameter can be specified as boolean (<tt>true</tt>) for default animation effects.</p>
+ * <pre><code>
+// default animation
+el.setWidth(100, true);
+ * </code></pre>
+ *
+ * <p>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} animation options specific to Fx effects. The supported
+ * Element animation configuration options are:</p>
+<pre>
+Option Default Description
+--------- -------- ---------------------------------------------
+{@link Ext.Fx#duration duration} .35 The duration of the animation in seconds
+{@link Ext.Fx#easing easing} easeOut The easing method
+{@link Ext.Fx#callback callback} none A function to execute when the anim completes
+{@link Ext.Fx#scope scope} this The scope (this) of the callback function
</pre>
-</body>
+ *
+ * <pre><code>
+// Element animation options object
+var opt = {
+ {@link Ext.Fx#duration duration}: 1,
+ {@link Ext.Fx#easing easing}: 'elasticIn',
+ {@link Ext.Fx#callback callback}: this.foo,
+ {@link Ext.Fx#scope scope}: this
+};
+// animation with some options set
+el.setWidth(100, opt);
+ * </code></pre>
+ * <p>The Element animation object being used for the animation will be set on the options
+ * object as "anim", which allows you to stop or manipulate the animation. Here is an example:</p>
+ * <pre><code>
+// using the "anim" property to get the Anim object
+if(opt.anim.isAnimated()){
+ opt.anim.stop();
+}
+ * </code></pre>

+ * types of listeners:<br>
+ * <br>
+ * 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.<div style="margin: 5px 20px 20px;">

+el.on('click', this.onClick, this, {
+ single: true,
+ delay: 100,
+ stopEvent : true,
+ forumId: 4
+});</code></pre></p>
+ * <p>
+ * <b>Attaching multiple handlers in 1 call</b><br>
+ * The method also allows for a single argument to be passed which is a config object containing properties
+ * which specify multiple handlers.</p>
+ * <p>
+ * Code:<pre><code>
+el.on({
+ 'click' : {
+ fn: this.onClick,
+ scope: this,
+ delay: 100
+ },
+ 'mouseover' : {
+ fn: this.onMouseOver,
+ scope: this
+ },
+ 'mouseout' : {
+ fn: this.onMouseOut,
+ scope: this
+ }
+});</code></pre>
+ * <p>
+ * Or a shorthand syntax:<br>
+ * Code:<pre><code></p>
+el.on({
+ 'click' : this.onClick,
+ 'mouseover' : this.onMouseOver,
+ 'mouseout' : this.onMouseOut,
+ scope: this
+});
+ * </code></pre></p>
+ * <p><b>delegate</b></p>
+ * <p>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:<pre><code>
+// using this markup:
+<div id='elId'>
+ <p id='p1'>paragraph one</p>
+ <p id='p2' class='clickable'>paragraph two</p>
+ <p id='p3'>paragraph three</p>
+</div>
+// 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'
