Here is your fiddle, fixed to work: http://jsfiddle.net/3q9Ma/223/

You were calling create_nodewith an array, which was wrong, also the string value 'null'was not the correct way to create a root node - use the special string value '#'(in later versions nullworks too, but not as a string).

您正在create_node使用数组调用，这是错误的，字符串值'null'也不是创建根节点的正确方法 - 使用特殊字符串值'#'（在更高版本中null也可以使用，但不能作为字符串）。

You might consider upgrading the jstree version - your fiddle was using a very early beta. Also keep in mind jstree itself does not require Angular.

您可能会考虑升级 jstree 版本 - 您的小提琴使用的是非常早期的测试版。还要记住 jstree 本身不需要 Angular。
