本文實例講述了jQuery插件zTree實現的基本樹與節點獲取操作。分享給大家供大家參考，具體如下：
1、實現代碼：
<!DOCTYPE html><html><head> <title>zTree實現基本樹</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:"武漢市", open:true}, { id:111, pId:11, name:"漢口"}, { id:112, pId:11, name:"漢陽"}, { id:113, pId:11, name:"武昌"}, { id:12, pId:1, name:"黃石市"}, { id:121, pId:12, name:"黃石港區"}, { id:122, pId:12, name:"西塞山區"}, { id:123, pId:12, name:"下陸區"}, { id:124, pId:12, name:"鐵山區"}, { id:13, pId:1, name:"黃岡市"}, { id:2, pId:0, name:"湖南省", open:true}, { id:21, pId:2, name:"長沙市", open:true}, { id:211, pId:21, name:"芙蓉區"}, { id:212, pId:21, name:"天心區"}, { id:213, pId:21, name:"岳麓區"}, { id:214, pId:21, name:"開福區"}, { id:22, pId:2, name:"株洲市"}, { id:221, pId:22, name:"天元區"}, { id:222, pId:22, name:"荷塘區"}, { id:223, pId:22, name:"蘆淞區"}, { id:224, pId:22, name:"石峰區"}, { id:23, pId:2, name:"湘潭市"}, { id:231, pId:23, name:"雨湖區"}, { id:232, pId:23, name:"岳塘區"}, { id:233, pId:23, name:"湘鄉市"}, { id:234, pId:23, name:"韶山市"} ]; $(document).ready(function(){ $.fn.zTree.init($("#baseTree"), setting, zNodes); }); /** * 獲取選中節點的編碼和名稱 */ 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("樹節點編碼："+nodeId+"/n"+"樹節點名稱："+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="獲取選中節點"/> </div></div></body></html>2、設計效果圖：
（1）初始化
（2）單擊按鈕
3、設計說明
