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
|
|
|
21 |
nodes from a specified URL. The response must be a JavaScript Array definition
|
|
|
22 |
whose elements are node definition objects. eg:
|
|
|
23 |
<pre><code>[{
|
|
|
24 |
id: 1,
|
|
|
25 |
text: <em>'A leaf Node'</em>,
|
|
|
26 |
leaf: true
|
|
|
27 |
},{
|
|
|
28 |
id: 2,
|
|
|
29 |
text: <em>'A folder Node'</em>,
|
|
|
30 |
children: [{
|
|
|
31 |
id: 3,
|
|
|
32 |
text: <em>'A child Node'</em>,
|
|
|
33 |
leaf: true
|
|
|
34 |
}]
|
|
|
35 |
}]</code></pre>
|
|
|
36 |
<br><br>
|
|
|
37 |
A server request is sent, and child nodes are loaded only when a node is expanded.
|
|
|
38 |
The loading node's id is passed to the server under the parameter name "node" to
|
|
|
39 |
enable the server to produce the correct child nodes.
|
|
|
40 |
<br><br>
|
|
|
41 |
To pass extra parameters, an event handler may be attached to the "beforeload"
|
|
|
42 |
event, and the parameters specified in the TreeLoader's baseParams property:
|
|
|
43 |
<pre><code>myTreeLoader.on(<em>"beforeload"</em>, <b>function</b>(treeLoader, node) {
|
|
|
44 |
<b>this</b>.baseParams.category = node.attributes.category;
|
|
|
45 |
}, <b>this</b>);</code></pre><
|
|
|
46 |
This would pass an HTTP parameter called "category" to the server containing
|
|
|
47 |
the value of the Node's "category" attribute. </div>

<b>Combining Options</b><br>
|
|
|
221 |
Using the options argument, it is possible to combine different types of listeners:<br>
|
|
|
222 |
<br>
|
|
|
223 |
A normalized, delayed, one-time listener that auto stops the event and passes a custom argument (forumId)
|
|
|
224 |
<pre><code>el.on(<em>'click'</em>, <b>this</b>.onClick, <b>this</b>, {
|
|
|
225 |
single: true,
|
|
|
226 |
delay: 100,
|
|
|
227 |
forumId: 4
|
|
|
228 |
});</code></pre>
|
|
|
229 |
<p>
|
|
|
230 |
<b>Attaching multiple handlers in 1 call</b><br>
|
|
|
231 |
The method also allows for a single argument to be passed which is a config object containing properties
|
|
|
232 |
which specify multiple handlers.
|
|
|
233 |
<p>
|
|
|
234 |
<pre><code>foo.on({
|
|
|
235 |
<em>'click'</em> : {
|
|
|
236 |
fn: <b>this</b>.onClick,
|
|
|
237 |
scope: <b>this</b>,
|
|
|
238 |
delay: 100
|
|
|
239 |
},
|
|

240 |
