How to check whether selected node is having child nodes or not in jstree?

I m taking selected node by following code.

var selected=$("#warehouseTree").jstree('get_selected');

and now i want to check for child nodes for sel开发者_StackOverflow中文版ected node.

This is simply how you extract children information from a specific node.

$("#tree_2").jstree().get_node("13").children

Try this:

var tree = jQuery.jstree._reference('#warehouseTree');
var children = tree._get_children(selected);

Which will return an array of jQuery objects of the children of the selected node.

this will help.

   if(selected.children().size() > 0)
    {
    //has child
    }

This is how you can check whether a node has children or not.

var tree = jQuery.jstree._reference('#warehouseTree');
var isParent = instance.is_parent(selected);
console.log(isParent) //  true for directory
