本文实例讲述了jQuery插件zTree实现的基本树与节点获取操作。分享给大家供大家参考,具体如下:

1、实现代码:


<!DOCTYPE html>
<html>
<head>
 <title>zTree实现基本树</title>
 <meta http-equiv="content-type" content="text/html; charset=UTF-8">
 <link rel="stylesheet" type="text/css" href="zTree_v3/css/demo.css" rel="external nofollow" >
 <link rel="stylesheet" type="text/css" href="zTree_v3/css/zTreeStyle/zTreeStyle.css" rel="external nofollow" >
 <script type="text/javascript" src="zTree_v3/js/jquery-1.4.4.min.js"></script>
 <script type="text/javascript" src="zTree_v3/js/jquery.ztree.core.min.js"></script>
 <script type="text/javascript">
 <!--
 var setting = {
 data: {
 simpleData: {
 enable: true
 }
 }
 };
 var zNodes =[
 { id:1, pId:0, name:"湖北省", open:true},
 { id:11, pId:1, name:"武汉市", open:true},
 { id:111, pId:11, name:"汉口"},
 { id:112, pId:11, name:"汉阳"},
 { id:113, pId:11, name:"武昌"},
 { id:12, pId:1, name:"黄石市"},
 { id:121, pId:12, name:"黄石港区"},
 { id:122, pId:12, name:"西塞山区"},
 { id:123, pId:12, name:"下陆区"},
 { id:124, pId:12, name:"铁山区"},
 { id:13, pId:1, name:"黄冈市"},
 { id:2, pId:0, name:"湖南省", open:true},
 { id:21, pId:2, name:"长沙市", open:true},
 { id:211, pId:21, name:"芙蓉区"},
 { id:212, pId:21, name:"天心区"},
 { id:213, pId:21, name:"岳麓区"},
 { id:214, pId:21, name:"开福区"},
 { id:22, pId:2, name:"株洲市"},
 { id:221, pId:22, name:"天元区"},
 { id:222, pId:22, name:"荷塘区"},
 { id:223, pId:22, name:"芦淞区"},
 { id:224, pId:22, name:"石峰区"},
 { id:23, pId:2, name:"湘潭市"},
 { id:231, pId:23, name:"雨湖区"},
 { id:232, pId:23, name:"岳塘区"},
 { id:233, pId:23, name:"湘乡市"},
 { id:234, pId:23, name:"韶山市"}
 ];
 $(document).ready(function(){
 $.fn.zTree.init($("#baseTree"), setting, zNodes);
 });
 /**
 * 获取选中节点的编码和名称
 */
 function findSelect()
 {
 var treeObj = $.fn.zTree.getZTreeObj("baseTree");
 var nodes = treeObj.getSelectedNodes();
 for(var i=0;i<nodes.length;i++)
 {
 var nodeId = nodes[i].id;
 var nodeName = nodes[i].name;
 alert("树节点编码:"+nodeId+"\n"+"树节点名称:"+nodeName);
 }
 }
 //-->
 </script>
 </head>
<body>
<div class="content_wrap">
 <div class="zTreeDemoBackground left" style="text-align: center;">
 <ul id="baseTree" class="ztree" style="height: 300px; width:200px; overflow-y: auto"></ul>
 <input type="button" id="btn" onclick="findSelect()" value="获取选中节点"/>
 </div>
</div>
</body>
</html>

2、设计效果图:

(1)初始化

(2)单击按钮

3、设计说明

获取 zTree 当前被选中的节点数据集合


var treeObj = $.fn.zTree.getZTreeObj("baseTree");
var nodes = treeObj.getSelectedNodes();
