　The use of jQueryEasyUI is actually very simple. In the first use, I still encountered some problems, so I made a simple example and copied the document.

Page code:

<html>
<head>
 <title>jQuery EasyUI学习</title>
 <script src="../../Scripts/jquery-1.4.1.min.js" type="text/javascript"></script>
 <script src="../../Scripts/jquery.easyui.min.js" type="text/javascript"></script>
 <link href="../../themes/default/easyui.css" rel="stylesheet" type="text/css" />
 <link href="../../themes/icon.css" rel="stylesheet" type="text/css" />
 <script type="text/javascript">
 $(function() {
  $("#Tree").tree({
  url: "/Home/GetJson",
  onClick: function(node) {
   alert(node.text);
  }
  })
 })
 </script>
</head>
<body>
 <ul id="Tree">
 </ul>
</body>
</html>

Backend code:

public class HomeController : Controller
 {
 public ActionResult Index()
 {
  return View();
 }
 public ActionResult About()
 {
  return View();
 }
 public ActionResult GetJson()
 {
  Node node4 = new Node(4, "java从入门到精通", "open", null);
  Node node5 = new Node(5, "30天精通C#", "open", null);
  List<Node> ListNode2 = new List<Node>() { node4 };
  List<Node> ListNode3 = new List<Node>() { node5 };
  Node node2 = new Node(2, "java分类", "closed", ListNode2);
  Node node3 = new Node(3, "c#分类", "closed", ListNode3);
  List<Node> ListNode1 = new List<Node>() { node2, node3 };
  Node node1 = new Node(1, "图书分类", "closed", ListNode1);
  List<Node> ListNode0 = new List<Node>() { node1 };
  return Json(ListNode0, JsonRequestBehavior.AllowGet);
 }
 }
 public class Node
 {
 public Node(int Id,string Text,string IconCls, List<Node> Children)
 {
  id = Id;
  text = Text;
  iconCls = IconCls;
  children = Children;
 }
 public int id
 {
  get;
  set;
 }
 public string text
 {
  get;
  set;
 }
 public string iconCls
 {
  get;
  set;
 }
 public List<Node> children
 {
  get;
  set;
 }
 }

There is no method calling example in the above example, and the jQueryEasyUI method calling is strange Weirdly said, Such as:

alert($("#Tree").tree(&#39;getRoot&#39;).text);　　　　//调用getRoot方法
$("#Tree").tree(&#39;collapseAll&#39;);　　　　　　　　 //调用collapseAll方法
