推荐答案
这将从该页面获取HTML内容，但CSS，样式和任何其他动态效果都不会下载.玩这个.
This will get the HTML content from that page but the CSS, styling and any other dynamic effects will not be downloaded. Play around with this.
<html>
<head>
<script type="text/javascript">
function loadXMLDoc()
{
var xmlhttp;
if (window.XMLHttpRequest)
{// code for IE7+, Firefox, Chrome, Opera, Safari
xmlhttp=new XMLHttpRequest();
}
else
{// code for IE6, IE5
xmlhttp=new ActiveXObject("Microsoft.XMLHTTP");
}
xmlhttp.onreadystatechange=function()
{
if (xmlhttp.readyState==4 && xmlhttp.status==200)
{
document.getElementById("myDiv").innerHTML=xmlhttp.responseText;
}
}
xmlhttp.open("GET","http://www.sehajpal.com",true);
xmlhttp.send();
}
</script>
</head>
<body>
<div id="myDiv"><h2>Result HTML goes here.</h2></div>
<button type="button" önclick="loadXMLDoc()">Fetch HTML</button>
</body>
</html>
