How to get all checked nodes in jstree?

Question

I need to export my nodes like this:

function recursive_simplify(node){ 
    if(node.children){
        for(var i =0;i

        

Answer 1

get_all_checked: function(obj)
           {
                obj = !obj || obj === -1 ? this.get_container() : this._get_node(obj);
                return obj.find(".jstree-checked, .jstree-undetermined");
            };

use :

var checkedNodes = $(this).jstree("get_all_checked");
