在jstree中按ID获取节点

Question

I have ids and I need to get the corresponding nodes. 我有ID，需要获取相应的节点。

But how ? 但是如何？

Here, "n" is my node id. 在这里，“ n”是我的节点ID。 How can i get the jstree object? 如何获取jstree对象？

$.each(data.node.children,function(k,v){
 var n = $("#jstree_demo_div").find("[id='"+v+"']");
 console.log(n);
});

Regards. 问候。

Answer 1

To get the reference to the DOMElement you just need to call .get(0) on the jQuery object. 要获取对DOMElement的引用，您只需要在jQuery对象上调用.get(0) 。

$.each(data.node.children,function(k,v){
 var n = $("#jstree_demo_div").find("[id='"+v+"']").get(0);
 console.log(n);
});

Unless you are working with invalid html, this can be shortened to the following: 除非使用无效的html，否则可以将其缩短为以下内容：

$.each(data.node.children,function(k,v){
 var n = $('#'+v).get(0);
 console.log(n);
});

Solved. 解决了。

I didn't have to get the node by id. 我不必按ID来获取节点。

I get the JSON of the parent and find children. 我得到父级的JSON并找到子级。
