使用简单json数据构造ztree

   <div data-options="iconCls:'icon-remove'" title="功能菜单">
    <ul id="ztree2" class="ztree"></ul>
   </div>

 <!-- 使用简单json数据构造ztree -->
 <script type="text/javascript">
  $(function() {
   var setting = {
    data: {
      simpleData: {
       enable: true
      }
    }
   };

   var zNodes = [
    {"id":1, "pId":0, "name":"test1"},
    {"id":11, "pId":1, "name":"test11"},
    {"id":12, "pId":1, "name":"test12"},
    {"id":111, "pId":11, "name":"test111"},
    {"id":2, "pId":0, "name":"test2"},
    {"id":3, "pId":0, "name":"test3"},
    {"id":31, "pId":2, "name":"test31"}
   ];

   $.fn.zTree.init($("#ztree2"), setting, zNodes);
  });
 </script>

发送ajax请求获取动态json数据构造ztree

json内容

[
  { "id":"11", "pId":"0", "name":"菜单1"},
  { "id":"111", "pId":"11", "name":"菜单11", "page":"xx.action"},
  { "id":"112", "pId":"11", "name":"菜单12","page":"xx.action"},
  { "id":"113", "pId":"11", "name":"菜单13", "page":"xx.action"},

  { "id":"13", "pId":"0", "name":"菜单3"},
  { "id":"131", "pId":"13", "name":"菜单31","page":"xx.action"},
  { "id":"132", "pId":"13", "name":"菜单32","page":"xx.action"}

   <div data-options="iconCls:'icon-remove'" title="非功能菜单">
    <ul id="ztree3" class="ztree"></ul>

 <!-- 发送ajax请求获取动态json数据构造ztree -->
 <script type="text/javascript">
  $(function() {

    dataType:'json',
    success:function (data) {
      $.fn.zTree.init($("#ztree3"), setting, data);
    }
   });

 </script>

为ztree节点绑定事件动态添加选项卡

json内容

[
  { "id":"11", "pId":"0", "name":"菜单1"},
  { "id":"111", "pId":"11", "name":"菜单11", "page":"xx.action"},
