EXT 的 Treegrid 需要什么格式的JSON数据 ?

[links_234]

我现在用的是普通的GRIDPANEL 改成Treegrid后并未报错 但数据不显示
是因为后台的JSON格式不正确吗 ? JSON如下：

{root:[{"MODULE_CD":1,"MODULE_NM":"客户产品依赖","PARENT_CD":0,"PARENT_NM":"","URL":"","INDATE":"","UPTDATE":""},{"MODULE_CD":28,"MODULE_NM":"仓库数据维护","PARENT_CD":17,"PARENT_NM":"","URL":"","INDATE":"","UPTDATE":""},{"MODULE_CD":31,"MODULE_NM":"工厂统计报表","PARENT_CD":0,"PARENT_NM":"","URL":"","INDATE":"","UPTDATE":""}],success:true}

[quote=引用 2 楼 showbo 的回复:] 肯定不正确了，ext不是有demo，自己看demo提供的数据源，而且是treestore，grid的store数据源不行 谢谢 我刚拼凑成功了JSON 然后在普通Grid上显示出了下面这几个最父级数据 子级数据没有显示 如果我用TreeGrid 就报错 TypeError: cs is undefined 另外TreeStore我在3.4的API里搜不到啊... {root:[{"MODULE_CD":1,"MODULE_NM":"客户产品依赖","PARENT_CD":0,"PARENT_NM":null,"URL":"","INDATE":null,"UPTDATE":null,"leaf":false,"iconCls":null,"children":null},{"MODULE_CD":5,"MODULE_NM":"订单发货","PARENT_CD":0,"PARENT_NM":null,"URL":"","INDATE":null,"UPTDATE":null,"leaf":false,"iconCls":null,"children":null},{"MODULE_CD":10,"MODULE_NM":"生产调度管理","PARENT_CD":0,"PARENT_NM":null,"URL":"","INDATE":null,"UPTDATE":null,"leaf":false,"iconCls":null,"children":null},{"MODULE_CD":17,"MODULE_NM":"出入库管理","PARENT_CD":0,"PARENT_NM":null,"URL":"","INDATE":null,"UPTDATE":null,"leaf":false,"iconCls":null,"children":null},{"MODULE_CD":28,"MODULE_NM":"仓库数据维护","PARENT_CD":17,"PARENT_NM":null,"URL":"","INDATE":null,"UPTDATE":null,"leaf":false,"iconCls":null,"children":null},{"MODULE_CD":31,"MODULE_NM":"工厂统计报表","PARENT_CD":0,"PARENT_NM":null,"URL":"","INDATE":null,"UPTDATE":null,"leaf":false,"iconCls":null,"children":null}],success:true}

肯定不正确了，ext不是有demo，自己看demo提供的数据源，而且是treestore，grid的store数据源不行
