zTree實現刪除樹子節點
1、實現源代碼

var zNodes =[

$(document).ready(function(){
$.fn.zTree.init($("#baseTree"), setting, zNodes);
});
/**
* 刪除選中的子節點
*/
function removeNodes()
{
var treeObj = $.fn.zTree.getZTreeObj("baseTree");
//選中節點
var nodes = treeObj.getSelectedNodes();
for (var i=0, l=nodes.length; i < l; i++)
{
//刪除選中的子節點
treeObj.removeChildNodes(nodes[i]);

</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="刪除子節點"/>
</div>
</div>
</body>
</html>2、實現結果
（1）初始化
（2）選擇“武漢”，然后單擊“刪除子節點”
（3）選擇“武漢市”。然后單擊“刪除子節點”。不能再刪除子節點
3、源代碼說明
//刪除選中的子節點
treeObj.removeChildNodes(nodes[i]);
