<div class="short">Appends an event handler to this component</div> |

Appends an event handler to this component <div class="mdetail-params"> |
<strong>Parameters:</strong> |
<ul><li><code>eventName</code> : String<div class="sub-desc">The type of event to listen for</div></li><li><code>handler</code> : Function<div class="sub-desc">The method the event invokes</div></li><li><code>scope</code> : Object<div class="sub-desc">(optional) The scope in which to execute the handler |
function. The handler function's "this" context.</div></li><li><code>options</code> : Object<div class="sub-desc">(optional) An object containing handler configuration |
properties. This may contain any of the following properties:<ul> |
<li><b>scope</b> : Object<p class="sub-desc">The scope in which to execute the handler function. The handler function's "this" context.</p></li> |
<li><b>delay</b> : Number<p class="sub-desc">The number of milliseconds to delay the invocation of the handler after the event fires.</p></li> |
<li><b>single</b> : Boolean<p class="sub-desc">True to add a handler to handle just the next firing of the event, and then remove itself.</p></li> |
<li><b>buffer</b> : Number<p class="sub-desc">Causes the handler to be scheduled to run in an <a ext:cls="Ext.util.DelayedTask" href="output/Ext.util.DelayedTask.html">Ext.util.DelayedTask</a> delayed |
by the specified number of milliseconds. If the event fires again within that time, the original |
handler is <em>not</em> invoked, but the new handler is scheduled in its place.</p></li> |
</ul><br> |
<p> |
<b>Combining Options</b><br> |
Using the options argument, it is possible to combine different types of listeners:<br> |
<br> |
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId) |
<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, { |
single: true, |
delay: 100, |
forumId: 4 |
});</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>foo.on({ |
<em>'click'</em> : { |
fn: <b>this</b>.onClick, |
scope: <b>this</b>, |
delay: 100 |
}, |
<em>'mouseover'</em> : { |
fn: <b>this</b>.onMouseOver, |
scope: <b>this</b> |
}, |
<em>'mouseout'</em> : { |
fn: <b>this</b>.onMouseOut, |
scope: <b>this</b> |
} |
});</code></pre> |
<p> |
Or a shorthand syntax:<br> |
<pre><code>foo.on({ |
<em>'click'</em> : <b>this</b>.onClick, |
<em>'mouseover'</em> : <b>this</b>.onMouseOver, |
<em>'mouseout'</em> : <b>this</b>.onMouseOut, |
scope: <b>this</b> |
