本文实例讲述了jQuery插件zTree实现更新根节点中第i个节点名称的方法。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:131, pId:13, name:"黄州区"},
 { id:132, pId:13, name:"麻城市"},
 { id:133, pId:13, name:"武穴市"},
 { id:134, pId:13, name:"团风县"},
 { id:135, pId:13, name:"浠水县"},
 { id:136, pId:13, name:"罗田县"},
 { id:137, pId:13, name:"英山县"},
 { 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"}
 $(document).ready(function(){
 $.fn.zTree.init($("#baseTree"), setting, zNodes);
 * 更新根节点中第i个节点的名称
 function updateNodes()
 var treeObj = $.fn.zTree.getZTreeObj("baseTree");
 //获取节点
 var nodes = treeObj.getNodes();
 if (nodes.length 0)
 for(var i=0;i nodes.length;i++)
 // 更新根节点中第i个节点的名称
 nodes[i].name = "省份名称";
 treeObj.updateNode(nodes[i]);
 //-- 
 /script 
 /head 
 body 
 div 
 div 
 ul id="baseTree" /ul 
 input type="button" id="btn" value="更新根节点中第i个节点的名称"/ 
 /div 
 /div 
 /body 
 /html 

2、运行效果:

(1)初始化

(2)单击按钮后

3、设计说明

// 更新根节点中第i个节点的名称
nodes[i].name = "省份名称";
treeObj.updateNode(nodes[i]);
