试一试,定义clearText()函数,完成节点内容的删除。请教一下各位大神,我这样写问题出在哪里?
<!DOCTYPE HTML>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8">
<title>无标题文档</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");
for(i=0;i<content.childNodes.length;i++);
{
var x=document.getElementById(content[i])
var y=content.removeChild(x);
document.write("删除内容:"+y.innerHTML);
}// 在此完成该函数
}
</script>
<button onclick="clearText()">清除节点内容</button>
</body>
</html>
