首先引入相应的 JS 文件和样式文件

然后初始化列表界面

此部分对应的后台只需要返回一个 List 集合即可，用于初始化界面，其效果如下：

由于需要在展开节点的时候需要动态加载，所以需要实现 expend 方法

在展开节点的时候，需要根据父节点去查找其下级几点的信息，并返回给页面，实现动态加载树形图，其效果如下：

2.ztree

引入 JS 和 CSS 样式

1 <link rel="stylesheet" href="/plugins/ztree/css/zTreeStyle/zTreeStyle.css" type="text/css">
2 <script type="text/javascript" src="/plugins/ztree/js/jquery.ztree.core.js"></script>
3 <script type="text/javascript" src="/plugins/ztree/js/jquery.ztree.excheck.js"></script>

编写一个div，用于存放树形图

1  <div class="form-group clearfix">
2           <label id="parentdmLabel" class="col-sm-2 control-label" style="text-align:right">菜单权限</label>
3           <div class="col-sm-10">
4               <div id="treeDemoUpdate" class="ztree"></div>
5           </div>
6   </div>

JS部分代码

 1 <SCRIPT type="text/javascript">
 2     var setting = {
 3         check: {
 4             enable: true
 5         },
 6         data: {
 7             simpleData: {
 8                 enable: true
 9             }
10         },
11         callback: {
12             beforeCheck:true,
13             onCheck:zTreeOnClick
14         }
15     };
16     var zNodes ;
17     var code;
18     function setCheck() {
19         var zTree = $.fn.zTree.getZTreeObj("treeDemoUpdate"),
20         type = {"Y": "ps", "N": "ps"};
21         zTree.setting.check.chkboxType = type;
22         showCode(‘setting.check.chkboxType = { "Y" : "‘ + type.Y + ‘", "N" : "‘ + type.N + ‘" };‘);
23     }
24     function showCode(str) {
25         if (!code) code = $("#code");
26         code.empty();
27         code.append("<li>" + str + "</li>");
28     }
29     $(document).ready(function () {
30        $.ajax({
31             url: ‘/admin/role/roleUpdateTree?roleId=‘+${tRole.roleId},
32             type: ‘post‘,
33             async: false ,
34             dataType: ‘json‘,
35             success: function (data) {
36                 zNodes=data;
37             }
38         });
39         $.fn.zTree.init($("#treeDemoUpdate"), setting, zNodes);
40         setCheck();
41         /* $("#py").bind("change", setCheck);
42          $("#sy").bind("change", setCheck);
43          $("#pn").bind("change", setCheck);
44          $("#sn").bind("change", setCheck);*/
45     });
46     
47     function zTreeOnClick(event, treeId, treeNode) {
48         var treeObj = $.fn.zTree.getZTreeObj("treeDemoUpdate");
49         var nodes = treeObj.getCheckedNodes(true);
50         var ids="";
51         for (var i = 0; i < nodes.length; i++) {
52             ids+=nodes[i].id+",";
53         }
54         //console.log(ids.substring(0,ids.length-1));
55         $("#permissionIds").val(ids.substring(0,ids.length-1));
56     }
57 </SCRIPT>

效果如下：
