jstree : Uncaught TypeError: Cannot read property 'children' of undefined

问题:

In my server I am returning a JSON object in the format of jsTree :

{"id":"value", "text":"value", "parent":"value"}  

I am getting it in my view through an Ajax call. Console.log shows me the details but jsTree gives me the error:

Uncaught TypeError: Cannot read property 'children' of undefined

View:

$.ajax({     url: "/category",     dataType: 'json',     type: 'GET',     success: function (res) {         $.each(res, function (i, obj) {             products.push([obj.id, obj.parent, obj.text]);             $('#jstree_demo_div').jstree({                 'core': {                     'data': [{ "id": obj.id, "parent": obj.parent != 0 ? obj.parent : "#", "text": obj.text }]                 }             });             console.log(obj.parent != 0 ? obj.parent : "#");         });      } });

I'm working with Ajax .

the problem I resolved it by declaring a new object javaScript that contains( id, parent, text)

exemple :

 var objJS = new Object();   objJS .id = ObjectJason.id;  objJS .parent = ObjectJason.parent!=="0" ?  ObjectJason.parent:"#";  objJS .text = ObjectJason.text; 

I declare an Array where I push all my objects and give it to 'data', like this

 $('#jstree_demo_div').jstree({                 'core': {                     'data': Array ;                 }             }); 

and it's working perfectly! I wish it will help a lot of people
