DOM節點刪除函數removeChild()用法執行個體，domremovechild
本文執行個體講述了DOM節點刪除函數removeChild()用法。分享給大家供大家參考。具體分析如下：
DOM刪除一個節點，必須要站在父節點的高度去刪除，代碼如下：
複製代碼 代碼如下:<html>
<head>
<script type="text/javascript">
function t(){
//思路：1.首先找到要刪除的節點；2. 找到它的父節點，在父節點的角度刪除子節點
var nodeul = document.getElementsByTagName('ul')[0];//找到父節點
var li_lan = nodeul.children[2];//找到要刪除的子節點
nodeul.removeChild(li_lan);//使用removeChild()函數刪除
}
</script>
</head>
<body>
<div id="container">
<ul>
<li>春天</li>
<li>夏天</li>
<li>藍天</li>
<li>秋天</li>
<li>冬天</li>
</ul>
</div>
<div id="copyul">
</div>
<hr />
<button onclick="t()" value="">刪除一個子節點</button>
</body>
</html>
