<h2>Description</h2>
|

|
|
<div id="description">
|
||
|
|
<p>The <code>html_data</code> plugin enables jsTree to convert nested unordered lists to interactive trees. jsTree can also get HTML from the server insert it into the DOM and convert that to a tree.</p>
|
||
|
|
<p>The basic structure you need to follow when supplying data in the HTML format is:</p>
|
||
|
|
<div class="code_f">
|
||
|
|
<pre class="brush:xml;">
|
||
|
|
<li>
|
||
|
|
<a href="some_value_here">Node title</a>
|
||
|
|
<!-- UL node only needed for children - omit if there are no children -->
|
||
|
|
<ul>
|
||
|
|
<!-- Children LI nodes here -->
|
||
|
|
</ul>
|
||
|
|
</li>
|
||
|
|
</pre>
|
||
|
|
</div>
|
||
|
|
<p>If you inspect the resulting structure you will find it a bit different - that is because jstree will automatically do some corrections.</p>
|
||
|
|
<div class="code_f">
|
||
|
|
<pre class="brush:xml;">
|
||
|
|
<!-- one of the three classes will be applied depending on node structure -->
|
||
|
|
<li class="[ jstree-open | jstree-closed | jstree-leaf ]">
|
||
|
|
<!-- an INS element is inserted -->
|
||
|
|
<ins class="jstree-icon">&#160;</ins>
|
||
|
|
<a href="some_value_here">
|
||
|
|
<!-- another INS element is inserted -->
|
||
|
|
<ins class="jstree-icon">&#160;</ins>
|
||
|
|
Node title
|
||
|
|
</a>
|
||
|
|
</li>
|
||
|
|
</pre>
|
||
|
|
</div>
|
||
|
|
<p>Both <code>ins</code> elements are inserted for visualization purposes. As for the class (<code>jstree-open</code>, <code>jstree-closed</code>) - you can specify that yourself to force the node to appear either closed or opened. Making a node with no children appear closed is often used - if you use ajax, opening a closed node with no children will result in jstree making a server call for the children (see the <a href="#demo3">demo below</a>).</p>

<div class="panel configuration">
|

|
|
<h3>data</h3>
|
||
|
|
<p class="meta">A HTML string (or <code>false</code> if not used). Default is <code>false</code>.</p>
|
||
|
|
<p>Specifies the content to load into the container and convert to a tree.</p>
|
||
|
|
<h3>ajax</h3>
|
||
|
|
<p class="meta">An object (or <code>false</code> if not used). Default is <code>false</code>.</p>
|
||
|
|
<p>The ajax config object is pretty much the same as the <a href="http://api.jquery.com/jQuery.ajax/">jQuery ajax settings object</a>.</p>
|
||
|
|
<p>You can set the <code>data</code> option to a function, that will be executed in the current tree's scope (<code>this</code> will be the tree instance) and gets the node about to be open as a paramater (or <code>-1</code> for initial load). Whatever you return in the function will be sent to the server as data (so for example you can send the node's ID).</p>
|
||
|
|
<p>You can set the <code>url</code> option to a function, that will be executed in the current tree's scope (<code>this</code> will be the tree instance) and gets the node about to be open as a paramater (or <code>-1</code> for initial load). Whatever you return in the <code>url</code> function will be used as the ajax URL (so that you can accomodate pretty paths such as /get_children/node_2).</p>
|
||
|
|
<p>The <code>error</code> and <code>success</code> functions (if present) also fire in the context of the tree, and if you return a value in the <code>success</code> function it will be used to populate the tree - this can be useful if you want to somehow change what the server returned on the client side before it is displayed in the tree.</p>
|
||
|
|
<h3>correct_state</h3>
|
||
|
|
<p class="meta">A Boolean. Default is <code>true</code>.</p>
|
||
|
|
<p>If this option is set to <code>true</code> if an AJAX request returns an empty result, the node that was about to be opened will be converted to a leaf node (the open icon will no longer be displayed).</p>
|
||
|
|
|
||
|
|
<p class="note"><strong>NOTE:</strong><br />If both <code>data</code> and <code>ajax</code> are not set, the current container's HTML is used to build the tree.<br />If both <code>data</code> and <code>ajax</code> are set the initial tree is rendered from the <code>data</code> string. When opening a closed node (that has no loaded children) an AJAX request is made.</p>
