找到一款可以自适应浏览器大小的js，对于iframe特别好用
使用代码如下
<html>
<head>
<script>
function SetCwinHeight(obj)
{
var cwin=obj;
if (document.getElementById)
{
if (cwin && !window.opera)
{
if (cwin.contentDocument && cwin.contentDocument.body.offsetHeight)
cwin.height = cwin.contentDocument.body.offsetHeight + 20; //FF NS
else if(cwin.Document && cwin.Document.body.scrollHeight)
cwin.height = cwin.Document.body.scrollHeight + 10;//IE
}
else
{
if(cwin.contentWindow.document && cwin.contentWindow.document.body.scrollHeight)
cwin.height = cwin.contentWindow.document.body.scrollHeight;//Opera
}
}
}
</script>
</head>
<body>
<iframe src="你引用的页面.html" onload="SetCwinHeight(this);" width="600px">
</body>
</html>
