Question

jquery easyui tree 怎么加载后台返回的json字符串

Answer 1

$('#tt').tree({
    url:'tree_data.json'
});

就这样就行了，tree节点的格式是

[{
    "id":1,
    "text":"Folder1",
    "iconCls":"icon-save",
    "children":[{
  "text":"File1",
  "checked":true
    },{
  "text":"Books",
  "state":"open",
  "attributes":{
   "url":"/demo/book/abc",
   "price":100
  },
  "children":[{
   "text":"PhotoShop",
   "checked":true
  },{
   "id": 8,
   "text":"Sub Bookds",
   "state":"closed"
  }]
    }]
},{
    "text":"Languages",
    "state":"closed",
    "children":[{
  "text":"Java"
    },{
  "text":"C#"
    }]
}]
