zTree实现删除树子节点
1、实现源代码

<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、实现结果
(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、源代码说明
//删除选中的子节点
treeObj.removeChildNodes(nodes[i]);
