本文实例讲述了jQuery插件zTree实现单独选中根节点中第一个节点的方法。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); }); /** * 单独选中根节点中第一个节点 */ function selectNodes() { var treeObj = $.fn.zTree.getZTreeObj("baseTree"); //获取节点 var nodes = treeObj.getNodes(); if (nodes.length>0) { var node = treeObj.selectNode(nodes[0]); alert(node); } } //--> </script> </head> <body> <div class="content_wrap"> <div class="zTreeDemoBackground left"> <ul id="baseTree" class="ztree" ></ul> <input type="button" id="btn" onclick="selectNodes()" value="单独选中根节点中第一个节点"/> </div> </div> </body> </html>
