江山十日雪，雪深江雾浓。开时刻的牵绊，邀阳光作伴，约清风同行，收拾起行囊，咱们去亲近草原吧，去亲近辽阔无边的草原。
本文实例讲述了jQuery插件zTree实现删除树子节点的方法。分享给大家供大家参考，具体如下：
1、实现代码：

<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: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"},
{ 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);
});
/**
* 删除选中的子节点
*/
function removeNodes()
{
var treeObj = $.fn.zTree.getZTreeObj("baseTree");
//选中节点
var nodes = treeObj.getSelectedNodes();
for (var i=0, l=nodes.length; i < l; i++)
{
//删除选中的子节点
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="删除子节点"/>
</div>
</div>
</body>
</html>
2、实现效果图：
（1）初始化
（2）选择“武汉”，然后单击“删除子节点”
（3）选择“武汉市”，然后单击“删除子节点”，不能再删除子节点
3、源码说明
//删除选中的子节点 treeObj.removeChildNodes(nodes[i]);
