问题描述

小提琴:

解决方案

使用此条件分配父对象:

obj.parent = data.parent ||null;

Fiddle : http://jsfiddle.net/p35cobgx/3/

Below is my tree structure :

Node
   Node-1
     Node-1-1......

Now I want to store back reference of all parents for each of the nodes like below :

Node

Node-1 (should store back reference of only Node because this is last parent for Node-1)

Node-1-1(should store back reference of all parents i.e Node-1 and Node because Node is the last parent for Node-1-1).

But problem with my code is i am unable to store reference of Node for Node-1-1.

解决方案

Use this condition for assigning the parent:

obj.parent = data.parent || null;
