本文實例講述了jQuery插件zTree實現(xiàn)刪除樹子節(jié)點的方法。分享給大家供大家參考，具體如下：
1、實現(xiàn)代碼：
<!DOCTYPE html><html><head> <title>zTree實現(xiàn)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(qū)"}, { id:122, pId:12, name:"西塞山區(qū)"}, { id:123, pId:12, name:"下陸區(qū)"}, { id:124, pId:12, name:"鐵山區(qū)"}, { id:13, pId:1, name:"黃岡市"}, { id:131, pId:13, name:"黃州區(qū)"}, { id:132, pId:13, name:"麻城市"}, { id:133, pId:13, name:"武穴市"}, { id:134, pId:13, name:"團(tuán)風(fēng)縣"}, { id:135, pId:13, name:"浠水縣"}, { id:136, pId:13, name:"羅田縣"}, { id:137, pId:13, name:"英山縣"}, { 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(qū)"}, { id:212, pId:21, name:"天心區(qū)"}, { id:213, pId:21, name:"岳麓區(qū)"}, { id:214, pId:21, name:"開福區(qū)"}, { id:22, pId:2, name:"株洲市"}, { id:221, pId:22, name:"天元區(qū)"}, { id:222, pId:22, name:"荷塘區(qū)"}, { id:223, pId:22, name:"蘆淞區(qū)"}, { id:224, pId:22, name:"石峰區(qū)"}, { id:23, pId:2, name:"湘潭市"}, { id:231, pId:23, name:"雨湖區(qū)"}, { id:232, pId:23, name:"岳塘區(qū)"}, { id:233, pId:23, name:"湘鄉(xiāng)市"}, { id:234, pId:23, name:"韶山市"} ]; $(document).ready(function(){ $.fn.zTree.init($("#baseTree"), setting, zNodes); }); /** * 刪除選中的子節(jié)點 */ function removeNodes() { var treeObj = $.fn.zTree.getZTreeObj("baseTree"); //選中節(jié)點 var nodes = treeObj.getSelectedNodes(); for (var i=0, l=nodes.length; i < l; i++) { //刪除選中的子節(jié)點 treeObj.removeChildNodes(nodes[i]); } } //--> </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="removeNodes()" value="刪除子節(jié)點"/> </div></div></body></html>2、實現(xiàn)效果圖：
（1）初始化
（2）選擇“武漢”，然后單擊“刪除子節(jié)點”
（3）選擇“武漢市”，然后單擊“刪除子節(jié)點”，不能再刪除子節(jié)點
3、源碼說明
//刪除選中的子節(jié)點treeObj.removeChildNodes(nodes[i]);
