zTree2.6、json数据的交互使用

?????? zTree 是一个依靠 jQuery 实现的多功能 “树插件”。通过对json数据的支持，是它他用起来特别的方便，下面就来介绍一下最简单的应用。

?jsp页面：

?

首先引入jquery的js文件

<script type="text/javascript" src="<%=basePath1%>module/taskMng/lhgdialog/jquery-1.7.1.min.js"></script>

??

然后引入ztree需要的js文件?

??????????????

<link rel="stylesheet" href="<%=basePath1>js/demo/zTreeStyle/zTreeStyle.css" type="text/css"><script type="text/javascript" src="<%=basePath1%>js/demo/jquery.ztree-2.6.js"></script>

?

 //初始化ztree设置var zTree1;         var  setting = {           isSimpleData : true,   //是否采用简单 Array 格式,true表示采用        treeNodeKey : "id",           treeNodeParentKey : "pId"//如果为true必须声明父子关系      };   /*简单 Array 格式var treeNodes = [   --%>      {"id":80, "pId":01, "name":"test1"},         {"id":81, "pId":80, "name":"test11"},         {"id":82, "pId":80, "name":"test12"},          {"id":111, "pId":81, "name":"test111"}       ];   */

?

//从后台读取数据var treeNodes = new Array();      $(function(){             var url="userListAction!getOrgJson.action";$.ajax({url: url,type:'post',async: false , success: function(data){var msg = eval('(' + data + ')');$.each(msg,function(i,item){treeNodes.push(new Node(item.id,item.parentId,item.deptName));});//alert(treeNodes[0].pId); }});});function Node(id,pid,name){this.id=id;this.pId=pid;this.name=name;}

??

//一切准备好后初始化树 $(document).ready(function(){           zTree1 = $("#treeDemo").zTree(setting, treeNodes);        }); //将ul标签加到想展示树的位置<ul id="treeDemo" name="code">public void getOrgJson(){try {deptDictWrappers = deptService.getCompanyDept(getLoginUserCompanyId());//查询出的listString jsonStr  = net.sf.json.JSONArray.fromObject(deptDictWrappers).toString();//转换成json字符串HttpServletResponse response = getResponse();response.setCharacterEncoding("utf8");PrintWriter out  = response.getWriter();out.println(jsonStr);//输出到前台} catch (IOException e) {log.error(e,e);} catch (Exception e) {log.error(e,e);}}
