Nodes in jsTree are essentially wrapped list items. This will get you a reference to the first one.

<pre><code>var n = $.tree.focused().get_node('li:eq(0)')
</code></pre>

You can replace <code>$.tree.focused()</code> if you have a reference to the tree.

To get the id, take the first matched element

<pre><code>if (n.length)
 id = n[0].id
</code></pre>

or you can use the jQuery attr function, which works on the first element in the set

<pre><code>id = n.attr('id');
</code></pre>

blocks|key|2984365|text|由于无法使用harpo的解决方案，并且不愿意使用Olivier的解决方案，因为它使用内部jsTree函数，所以我想出了一种不同的方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2984366|$('#tree').jstree('get_selected').attr('id')|code-block|syntax|javascript|2984367|就这么简单。get_selected函数返回选定列表项的数组。如果对该数组执行.attr，jQuery将查看列表中第一项。如果您需要多个选择的ID，则将其视为数组。|offset|length|style|CODE|2984368|entityMap^0|0|0|6|C|13|5|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]|$I|T|J|U|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|V|8|@]|9|@]|A|$]]]|N|$]]

Unable to get harpo's solution to work, and unwilling to use Olivier's solution as it uses internal jsTree functions, I came up with a different approach.

<pre><code>$('#tree').jstree('get_selected').attr('id')
</code></pre>

It's that simple. The <code>get_selected</code> function returns an array of selected list items. If you do <code>.attr</code> on that array, jQuery will look at the first item in the list. If you need IDs of multiple selections, then treat it as an array instead.

blocks|key|1052026|text|使用最新版本的Jstree，您可以执行以下操作：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1052027|<script+type="text/javascript>

With latest version of Jstree; you can do it as following:

<pre><code>&lt;script type="text/javascript&gt;
 var checked_ids = [];
 $('#your-tree-id).jstree("get_checked",null,true).each(function(){

&lt;/script&gt;

blocks|key|1575673|text|我在从具有多个选择的树中获取所选I时遇到问题。这是我得到它们的方式：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1575674|var+checked_ids+=+[];

I was having problems getting the selected ids from a tree with MULTIPLE selections. This is the way I got them:

<pre><code>var checked_ids = [];
$("#your-tree-id").jstree('get_selected').each(function(){ 
 checked_ids.push($(this).data('id')); 
});
</code></pre>

blocks|key|2984456|text|在我的例子中，数据调用不起作用。我使用attr函数成功地访问了节点数据。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2984457|$("#tree").jstree("get_selected").attr("my-data-name");|code-block|syntax|javascript|2984458|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

In my case, the data call doesnt work. 
I succeed in accessing my node data by using attr function. 

<pre><code>$("#tree").jstree("get_selected").attr("my-data-name");
</code></pre>

blocks|key|1055394|text|在jstree版本的3.1.1中，您可以直接从get_selected获取|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1055395|$("#<your+tree+container's+id>").jstree("get_selected")|code-block|syntax|javascript|1055396|entityMap^0|1|6|A|5|N|C|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@$9|N|A|O|B|C]|$9|P|A|Q|B|C]|$9|R|A|S|B|C]]|D|@]|E|$]]|$1|F|3|G|5|H|7|T|8|@]|D|@]|E|$I|J]]|$1|K|3|-4|5|6|7|U|8|@]|D|@]|E|$]]]|L|$]]

In <code>jstree</code> version <code>3.1.1</code>, you can get it directly from <code>get_selected</code>:

<pre><code>$("#&lt;your tree container's id&gt;").jstree("get_selected")
</code></pre>

blocks|key|1055413|text|只需使用|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1055414|var+nodeId+=+$('#FaqTreeView').jstree().get_selected("id")[0].id;|code-block|syntax|javascript|1055415|其中#FaqTreeView是包含jstree的div的id。|offset|length|style|CODE|1055416|entityMap^0|0|0|2|C|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@$I|R|J|S|K|L]]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Just use

<pre><code>var nodeId = $('#FaqTreeView').jstree().get_selected("id")[0].id;
</code></pre>

where <code>#FaqTreeView</code> is the id of your div that contains the jstree.

blocks|key|1052136|text|在某些情况下和/或jstree版本中，此解决方案不起作用。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1052137|$('#tree').jstree('get_selected').attr('id');|code-block|syntax|javascript|1052138|除了定义好的"id“，我什么也得不到。给我带来好处的是：|1052139|$("#tree").jstree("get_selected").toString();|1052140|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

In some cases and/or jstree versions this solution doesn't work.

<pre><code>$('#tree').jstree('get_selected').attr('id');
</code></pre>

Instead of defined "id" I get nothing.
What did the trick for me is:

<pre><code>$("#tree").jstree("get_selected").toString();
</code></pre>

blocks|key|1052156|text|在最新版本的jsTree+(在3.3.3中检查)中，您可以执行以下操作来获取ID数组：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1052157|var+ids+=+$('#tree').jstree('get_selected');|code-block|syntax|javascript|1052158|例如，这将返回["selected_id1",+"selected_id2",+"selected_id3"]。如果您想要获取所选节点(而不是ID)，您可以这样做：|offset|length|style|CODE|1052159|var+nodes+=+$('#tree').jstree('get_selected',+true);|1052160|current+docs包含更多信息。|1052161|entityMap|0|LINK|mutability|MUTABLE|url|https://www.jstree.com/api/#/?f=get_selected([full])^0|0|0|7|1C|0|0|0|C|0|0^^$0|@$1|2|3|4|5|6|7|Y|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|Z|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|10|8|@$I|11|J|12|K|L]]|9|@]|A|$]]|$1|M|3|N|5|D|7|13|8|@]|9|@]|A|$E|F]]|$1|O|3|P|5|6|7|14|8|@]|9|@$I|15|J|16|1|17]]|A|$]]|$1|Q|3|-4|5|6|7|18|8|@]|9|@]|A|$]]]|R|$S|$5|T|U|V|A|$W|X]]]]

In the most recent version of jsTree (checked at 3.3.3), you can do this to get an array of IDs:

<pre><code>var ids = $('#tree').jstree('get_selected');
</code></pre>

This will return, for example, <code>["selected_id1", "selected_id2", "selected_id3"]</code>. If you want to get the selected nodes (not IDs), you can do this:

<pre><code>var nodes = $('#tree').jstree('get_selected', true);
</code></pre>

The <a href="https://www.jstree.com/api/#/?f=get_selected([full])" rel="noreferrer">current docs</a> contain more information.

blocks|key|1575931|text|这些都是旧版本的老答案。从版本3.3.3开始，这将用于获取所选节点的所有属性。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1575932|$('#jstree').jstree().get_selected(true)[0]|code-block|syntax|javascript|1575933|如果您想要id，则在末尾添加.id。如果你复制上面的代码，你可以在web开发工具中查看所有其他的属性。|1575934|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

These are all old answers for old versions. As of version 3.3.3 this will work to get all attributes of the selected node.

<pre><code>$('#jstree').jstree().get_selected(true)[0]
</code></pre>

If you then want the id then add .id at the end. You can look at all the other attributes in web developer tools if you copy the above code.

blocks|key|1052214|text|您可以使用以下代码var+nodes+=+$("#jstree_demo_div").jstree(true).get_selected("full"，true)；//所选节点列表|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1052215|Nodes.id//将提供数组中第一个对象的id|1052216|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

You can use the following code
var nodes = $("#jstree_demo_div").jstree(true).get_selected("full", true);//List of selected node

nodes[0].id//Which will give id of 1st object from array

blocks|key|306636|text|要获取所有选定的ids，请使用以下代码|type|unstyled|depth|inlineStyleRanges|entityRanges|data|306637|var+selectedData+=+[];
var+selectedIndexes;
+selectedIndexes+=+$("#jstree").jstree("get_selected",+true);
jQuery.each(selectedIndexes,+function+(index,+value)+{
+++++selectedData.push(selectedIndexes[index].id);
+});|code-block|syntax|javascript|306638|现在，您已经在"selectedData“变量中拥有了所有选定的id|306639|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

to get all selected ids use the below code

<pre><code>var selectedData = [];
var selectedIndexes;
 selectedIndexes = $("#jstree").jstree("get_selected", true);
jQuery.each(selectedIndexes, function (index, value) {
 selectedData.push(selectedIndexes[index].id);
 });
</code></pre>

now you have all the selected id's in the "selectedData" variable

How can I get the id of the selected node in a <a href="http://www.jstree.com/demo/open_close" rel="noreferrer">jsTree</a>?

<pre><code>function createNewNode() {
 alert('test');
 var tree = $.tree.reference("#basic_html");
 selectedNodeId = xxxxxxxxx; //insert instruction to get id here
 tree.create({ data : "New Node Name" }, selectedNodeId);
}
</code></pre>

How do I get the id of the selected node in jsTree?
