Iframe自动适应宽度和高度(both IE and Firefox )

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
<title>iframe</title>
</head>
<body>
<script type="text/javascript">
function SetCwinHeight(){
  var bobo=document.getElementById("bobo"); //iframe id
  if (document.getElementById){
   if (bobo && !window.opera){
    if (bobo.contentDocument && bobo.contentDocument.body.offsetHeight){
     bobo.height = bobo.contentDocument.body.offsetHeight;
    }else if(bobo.Document && bobo.Document.body.scrollHeight){
     bobo.height = bobo.Document.body.scrollHeight;
    }
   }
  }
}
</script>
<iframe width="100%" id="bobo" onload="Javascript:SetCwinHeight()" height="1" frameborder="0" src="IFrame_myPage.aspx"></iframe>
这里有什么?
</body>
</html>

还有一种方法是不需要js控制的。与大家分享一下

上面是必须要替换的（如果是想尝试一下就Ctrl+C and Ctrl+V 一下。。。）
