<br><p>While <i>some</i> ExtJs Component classes export selected DOM events (e.g. "click", "mouseover" etc), this
is usually only done when extra value can be added. For example the <a href="output/Ext.DataView.html" ext:cls="Ext.DataView">DataView</a>'s
<b><code><a href="output/Ext.DataView.html#Ext.DataView-click" ext:member="click" ext:cls="Ext.DataView">click</a></code></b> event passing the node clicked on. To access DOM

has been rendered. A plugin can simplify this step:<pre><code><i>// Plugin is configured <b>with</b> a listeners config object.</i>
<i>// The Component is appended to the argument list of all handler functions.</i>
Ext.DomObserver = Ext.extend(Object, {
    constructor: <b>function</b>(config) {

<b>Combining Options</b><br>
Using the options argument, it is possible to combine different types of listeners:<br>
<br>
A delayed, one-time listener.
<pre><code>myDataView.on(<em>'click'</em>, this.onClick, this, {
single: true,
delay: 100
});</code></pre>
<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>
<pre><code>myGridPanel.on({
<em>'click'</em> : {
    fn: this.onClick,
    scope: this,
    delay: 100
},
<em>'mouseover'</em> : {
    fn: this.onMouseOver,
    scope: this
},
<em>'mouseout'</em> : {
    fn: this.onMouseOut,
    scope: this
}
});</code></pre>
<p>
Or a shorthand syntax:<br>
<pre><code>myGridPanel.on({
<em>'click'</em> : this.onClick,
<em>'mouseover'</em> : this.onMouseOver,
<em>'mouseout'</em> : this.onMouseOut,
 scope: this
