Easyui TreeGrid树形表格返回json数据不显示问题

老规矩还是先上图看效果：

这是正确的效果图差不多花了两天的时间去研究这个TreeGrid树形表格，错误原因就是 json 问题，先看返回的json数据：

{

在这讲解一下easyui TreeGrid的返回json格式的要求（必须严格按照官方的json格式）：

（1）基本json数据格式：

[
    {
        "m_id": 1,

以上是官方要求的json 格式，我返回的json格式有两个bug 第一问题：menu必须是rows 第二问题：menus 必须是children ，

如果你是使用的第一种json数据格式那么menu对象干掉 menus改为children

如果你是用的第二种json格式那么menu必须是rows menus改为children

以上就是我遇到的问题，希望能给同学带来帮助 六一儿童节快乐！
