使用标准json数据构造ztree

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"},

为ztree节点绑定事件动态添加选项卡
