JStree set href link and redirect

I use jstree in my rails application and I use json data for it, but I have problems: how can I set the link to nodes and href for it so that I can continue? Json looks like this:

var data = [
{
   "data":"\u041b\u0435\u0433\u043a\u043e\u0432\u044b\u0435 \u0430\u0432\u0442\u043e\u043c\u043e\u0431\u0438\u043b\u0438",
   "href":10001,
   "children":[
      {
         "data":"\u041a\u0443\u0437\u043e\u0432",
         "href":10101,
         "children":[
            {
               "data":"\u0422\u043e\u043f\u043b\u0438\u0432\u043d\u044b\u0439 \u0431\u0430\u043a / \u043a\u043e\u043c\u043f\u043b\u0435\u043a\u0442\u0443\u044e\u0449\u0438\u0435",
               "href":10316
            },
            {
               "data":"\u041a\u0440\u0435\u043f\u043b\u0435\u043d\u0438\u0435 \u0440\u0430\u0434\u0438\u0430\u0442\u043e\u0440\u0430",
               "href":10317
            },
            {
               "data":"\u041e\u0431\u043b\u0438\u0446\u043e\u0432\u043a\u0430 / \u0437\u0430\u0449\u0438\u0442\u0430 / \u043e\u0444\u043e\u0440\u043c\u043b\u0435\u043d\u0438\u0435 / \u044d\u043c\u0431\u043b\u0435\u043c\u044b / \u0437\u0430\u0449\u0438\u0442\u0430 \u0440\u0430\u0441\u043f\u044b\u043b.",
               "href":10319,
               "children":[
                  {
                     "data":"\u041e\u0431\u043b\u0438\u0446\u043e\u0432\u043a\u0430/\u0437\u0430\u0449\u0438\u0442\u043d\u0430\u044f \u043d\u0430\u043a\u043b\u0430\u0434\u043a\u0430",
                     "href":10840
                  },
                  { ................................

And js

$("#tree").jstree({
    plugins: ['themes', 'json_data'],
    json_data: {data: data},
      themes: {
          theme: 'apple'
      },   
  });
  $('#tree').bind('select_node.jstree', function(e,data) { 
    window.location.href = "123123"
});

but if I see the code, the link has href = "#". What's wrong?

The JSTree Node object does not have an href attribute. If you want to set it, you will need to use the attribute attrand include an array of key pairs that will identify any of the attributes that JSTree will place in your HTML output .. consider the following example:

$(function () {
$("#demo1").jstree({ 
    "json_data" : {
        "data" : [
            { 
                "data" : "A node", 
                "metadata" : { id : 23 },
                "children" : [ "Child 1", "A Child 2" ]
            },
            { 
                "attr" : { "id" : "li.node.id1" }, 
                "data" : { 
                    "title" : "Long format demo", 
                    "attr" : { "href" : "#" } 
                } 
            }
        ]
    },
    "plugins" : [ "themes", "json_data", "ui" ]
}).bind("select_node.jstree", function (e, data) { alert(data.rslt.obj.data("id")); });
});
