<h1>CORE</h1>
<h2>Description</h2>
<div id="description">
<h3>Including the files</h3>
<p>First of all, as jsTree is a jQuery component, you need to include jQuery itself. jsTree v.1.0 requires jQuery version 1.4.2</p>
<div class="code_f"><pre class="brush:xml;">
<script type="text/javascript" src="_lib/jquery.js"></script>
</pre></div>
<p>Then you need to include jsTree:</p>
<div class="code_f"><pre class="brush:xml;">
<script type="text/javascript" src="jquery.jstree.js"></script>
</pre></div>
<p>Or you could use the minified version:</p>
<div class="code_f"><pre class="brush:xml;">
<script type="text/javascript" src="jquery.jstree.min.js"></script>
</pre></div>
<p>You may change the path to whatever you like, but it is recommended not to rename <code>jquery.tree.js</code> or <code>jquery.tree.min.js</code> as the filenames may be used for path autodetection (for example in the <code>themes</code> plugin, but if you really need to rename the file most plugins will give you the option to set the path manually).</p>
<p>Additionally some plugins have dependencies - plugins that detect a dependency is missing will throw an error.</p>
<h3>Creating and configuring an instance</h3>
<p>You can create a tree in the following manner:</p>
<div class="code_f"><pre class="brush:js;">
jQuery("some-selector-to-container-node-here").jstree([ config_object ]);
</pre></div>
<p>In the optional config object you specify all the options that you want to set. Each plugin will describe its configuration and defaults. In the <a href="#configuration">configuration section</a> below you will find the options defined by the core. Each plugin's options (even the core) are set in their own subobject, which is named after the plugin. For example all of the core's options are set in the <code>core</code> key of the config object:</p>
<div class="code_f"><pre class="brush:js;">
jQuery("some-selector-to-container-node-here")
.jstree({
core : {
/* core options go here */
}
});
</pre></div>
<p class="note">Please note that if your options for a given plugin are the same as the defaults you may omit those options or omit the subobject completely (if you do not need to modify the defaults).</p>
<p>There is only one special config option that is not a part of any plugin - this is the <code>plugins</code> option, which defines a list of active plugins for the instance being created. Although many plugins may be included, only the ones listed in this option will be active. The only autoincluded "plugin" is the jstree core.</p>
<div class="code_f"><pre class="brush:js;">
jQuery("some-selector-to-container-node-here")
.jstree({
core : { /* core options go here */ },
plugins : [ "themes", "html_data", "some-other-plugin" ]
});
</pre></div>
<h3>Interacting with the tree</h3>
<p>To perform an operation programatically on a given instance you can use two methods:</p>
<div class="code_f"><pre class="brush:js;">
/* METHOD ONE */
jQuery("some-selector-to-container-node-here")
.jstree("operation_name" [, argument_1, argument_2, ...]);
/* METHOD TWO */
jQuery.jstree._reference(needle)
/* NEEDLE can be a DOM node or selector for the container or a node within the container */
.operation_name([ argument_1, argument_2, ...]);
</pre></div>
<p class="note">NOTE: Functions prefixed with <code>_</code> can not be called with method one.</p>
<p>jsTree uses events to notify of any changes happening in the tree. All events fire on the tree container in the <code>jstree</code> namespace and are named after the function that triggered them. Please note that for some events it is best to bind before creating the instance. For example:</p>
<div class="code_f"><pre class="brush:js;">
jQuery("some-container")
.bind("loaded.jstree", function (event, data) {
alert("TREE IS LOADED");
})
.jstree({ /* configuration here */ });
</pre></div>
<p>Please note the second parameter <code>data</code>. Its structure is as follows:</p>
<div class="code_f"><pre class="brush:js;">
{
"inst" : /* the actual tree instance */,
"args" : /* arguments passed to the function */,
"rslt" : /* any data the function passed to the event */,
"rlbk" : /* an optional rollback object - it is not always present */
}
</pre></div>
<p>There is also one special event - <code>before.jstree</code>. This events enables you to prevent an operation from executing. Look at the <a href="#demos">demo</a> below.</p>
</div>
<h2 id="configuration">Configuration</h2>
<div class="panel configuration">
<h3>html_titles</h3>
<p class="meta">Boolean. Default is <code>false</code>.</p>
<p>Defines whether titles can contain HTML code.</p>
<h3>animation</h3>
<p class="meta">A number. Default is <code>500</code>.</p>
<p>Defines the duration of open/close animations. <code>0</code> means no animation.</p>
<h3>initially_open</h3>
<p class="meta">An array. Default is <code>[]</code>.</p>
<p>Defines which nodes are to be automatically opened (if they are not present they will first be loaded) when the tree finishes loading - a list of IDs is expected.</p>
<h3>initially_load</h3>
<p class="meta">An array. Default is <code>[]</code>.</p>
<p>Defines which nodes are to be automatically loaded (but not opened) when the tree finishes loading - a list of IDs is expected.</p>
<h3>load_open</h3>
<p class="meta">A Boolean. Default is <code>false</code>.</p>
<p>When set to <code>true</code> forces loading of nodes marked as open, which do not have children. Otherwise nodes are only visualized as open without any children and opening/closing such a node won't cause it to load (make a server call).</p>
<h3>open_parents</h3>
<p class="meta">Boolean. Default is <code>true</code>.</p>
<p>If set to true opening a node will also open any closed ancestors it has (will open the whole chain down to this node).</p>
<h3>notify_plugins</h3>
<p class="meta">Boolean. Default is <code>true</code>.</p>
<p>If set to true loading nodes with some metadata will trigger some actions on the corresponding plugin. So you can actually set the selected/checked/etc</p>
<h3>rtl</h3>
<p class="meta">Boolean. Default is <code>false</code>.</p>
<p>Defines whether the tree is in right-to-left mode (also make sure you are using a RTL theme - for example the included <code>default-rtl</code>).</p>
<h3>strings</h3>
<p class="meta">Object. Default is <code>{ loading : "Loading ...", new_node : "New node" }</code>.</p>
<p>Contains strings needed for the operation of the tree so that you can localize.</p>
</div>

<p class="log" id="log2" style="clear:both;"> </p>
<p>The important part is <code>e.stopImmediatePropagation(); return false</code>.</p>
</div>
<h2 id="api">API</h2>
<div class="panel api">
<p class="note">Use extra caution when working with functions prefixed with an underscore - <code>_</code>!<br />Those functions are probably for internal usage only.</p>
<h3 id="jstree.defaults">jQuery.jstree.defaults</h3>
<p class="meta">An object. Default is a collection of all included plugin's defaults.</p>
<p>This object is exposed so that you can apply standart settings to all future instances</p>
<h3 id="jstree.plugin">jQuery.jstree.plugin ( plugin_name , plugin_data )</h3>
<p>This function is used by developers to extend jstree (add "plugins").</p>
<ul class="arguments">
<li>
<code class="tp">string</code> <strong>plugin_name</strong>
<p>The plugin name - it should be unique.</p>
</li>
<li>
<code class="tp">object</code> <strong>plugin_data</strong>
<p>The plugin itself. It consists of <code>__init</code> & <code>__destroy</code> functions, <code>defaults</code> object (that of course could be an array or a simple value) and a <code>_fn</code> object, whose keys are all the functions you are extending jstree with. You can overwrite functions (but you can in your function call the overriden old function), and you are responsible for triggering events and setting rollback points. You can omit any of the elements in the <code>plugin_data</code> param. Keep in mind jstree will automatically clear classes prepended with <code>jstree-</code> and all events in the <code>jstree</code> namespace when destroying a tree, so you do not need to worry about those.</p>
<p>Read jstree's code for examples on how to develop plugins.</p>
</li>
</ul>
<h3 id="jstree.rollback">jQuery.jstree.rollback ( rollback_object )</h3>
<p>This function will roll the tree back to the state specified by the rollback object</p>
<ul class="arguments">
<li>
<code class="tp">string</code> <strong>rollback_object</strong>
<p>Normally you will get this object from the event you are handling. You can of course use <code>.get_rollback()</code> to get the current state of the tree as a rollback object.</p>
<div class="code_f"><pre class="brush:js;">
$("some-container").bind("some-event.jstree", function (e, data) {
$.jstree.rollback(data.rlbk);
});</pre></div>
<p>Keep in mind that not all events will give you a rollback object - sometimes <code>data.rlbk</code> will be <code>false</code>.</p>
</li>
</ul>
<h3 id="jstree._focused">jQuery.jstree._focused ()</h3>
<p>Returns the currently focused tree instance on the page. If not interaction has been made - it is the last one to be created.</p>

<p>Returns the tree instance for the specified <code>needle</code>.</p>
<ul class="arguments">
<li>
<code class="tp">mixed</code> <strong>needle</strong>
<p>This can be a DOM node, jQuery node or selector pointing to the tree container, or an element within the tree.</p>
</li>
</ul>
<h3 id="jstree._instance">jQuery.jstree._instance ( index , container , settings )</h3>
<p>This function is used internally when creating new tree instances. Calling this function by itself is not enough to create a new instance. To create a tree use the documented method <code>$("selector").jstree([ options ])</code>.</p>
<h3 id="jstree._fn">jQuery.jstree._fn</h3>
<p>This object stores all functions included by plugins. It is used internally as a prototype for all instances - do not modify manually.</p>

<p>Returns the instance's settings object - the defaults, extended by your own config object.</p>
<h3 id="get_index">.get_index ()</h3>
<p>Returns the internal instance index.</p>

<p>Returns the jQuery extended container node of the tree.</p>
<h3 id="get_container_ul">.get_container_ul ()</h3>
<p>Returns the jQuery extended first UL node in the container of the tree.</p>
<h3 id="_set_settings">._set_settings ( settings )</h3>
<p>Replace the settings object with the <code>settings</code> param. Please note that not all plugins will react to the change. Unless you know exactly what you are doing you'd be better off recreating the tree with the new settings.</p>
<h3 id="init">.init ()</h3>
<p>This function is used internally when creating a new instance. Triggers an event, which fires after the tree is initialized, but not yet loaded.</p>
<h3 id="destroy">.destroy ()</h3>

<p>Stores the currently open nodes before refreshing. Used internally. Triggers an event.</p>
<h3 id="reopen">.reopen ( is_callback )</h3>
<p>Reopens all the nodes stored by <code>save_opened</code> or set in the <code>initially_open</code> config option on first load. It is called multiple times while reopening nodes - the <code>is_callback</code> param determines if this is the first call (<code>false</code>) or not. Used internally. Triggers an event.</p>
<h3 id="refresh">.refresh ( node )</h3>
<p>Refreshes the tree. Saves all open nodes, and reloads and then reopens all saved nodes. Triggers an event.</p>
<ul class="arguments">
<li>
<code class="tp">mixed</code> <strong>node</strong>

</li>
</ul>
<h3 id="loaded">.loaded ()</h3>
<p>A dummy function, whose purpose is only to trigger the loaded event. This event is triggered once after the tree's root nodes are loaded, but before any nodes set in <code>initially_open</code> are opened.</p>
<h3 id="set_focus">.set_focus ()</h3>
<p>Makes the current instance the focused one on the page. Triggers an event.</p>
<h3 id="unset_focus">.unset_focus ()</h3>
<p>If the current instance is focused this removes the focus. Triggers an event.</p>
<h3 id="is_focused">.is_focused ()</h3>
<p>Returns <code>true</code> if the current instance is the focused one, otherwise returns <code>false</code>.</p>
<h3 id="lock">.lock ()</h3>
