<div class="description"> |
A TreeLoader provides for lazy loading of an <a ext:cls="Ext.tree.TreeNode" href="output/Ext.tree.TreeNode.html">Ext.tree.TreeNode</a>'s child |
nodes from a specified URL. The response must be a JavaScript Array definition |
whose elements are node definition objects. eg: |
<pre><code>[{ |
id: 1, |
text: <em>'A leaf Node'</em>, |
leaf: true |
},{ |
id: 2, |
text: <em>'A folder Node'</em>, |
children: [{ |
id: 3, |
text: <em>'A child Node'</em>, |
leaf: true |
}] |
}]</code></pre> |
<br><br> |
A server request is sent, and child nodes are loaded only when a node is expanded. |
The loading node's id is passed to the server under the parameter name "node" to |
enable the server to produce the correct child nodes. |
<br><br> |
To pass extra parameters, an event handler may be attached to the "beforeload" |
event, and the parameters specified in the TreeLoader's baseParams property: |
<pre><code>myTreeLoader.on(<em>"beforeload"</em>, <b>function</b>(treeLoader, node) { |
<b>this</b>.baseParams.category = node.attributes.category; |
}, <b>this</b>);</code></pre>< |
This would pass an HTTP parameter called "category" to the server containing |
the value of the Node's "category" attribute. </div> |

<strong>Parameters:</strong> |

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> |
