添加依據document.write為何全消失了？
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>無標題文檔</title>
</head>
<body>
<div id="content">
? <h1>html</h1>
? <h1>php</h1>
? <h1>javascript</h1>
? <h1>jquery</h1>
? <h1>java</h1>
</div>
<script type="text/javascript">
function clearText() {
? var content=document.getElementById("content");
? var goal=document.getElementsByTagName('h1')[4];
?
? var x=content.removeChild(goal);
? document.write(x.innerHTML);
}
</script>
<button onclick="clearText()">清除節點內容</button>
</body>
</html>

? document.write(x.innerHTML); ?這段代碼將你原先寫的覆蓋了。
