iframe自适应大小

在嵌套动态的iframe页面时，需要自动适应iframe页面大小，代码如下

js方法

<script language="javascript">
<!--
function SetWinHeight(obj)
{
 var win=obj;
 if (document.getElementById)
 {
  if (win && !window.opera)
  {
   if (win.contentDocument && win.contentDocument.body.offsetHeight)
    win.height = win.contentDocument.body.offsetHeight;
   else if(win.Document && win.Document.body.scrollHeight)
    win.height = win.Document.body.scrollHeight;
  }
 }
}
-->
</script>

 

iframe Onload方法注册如下

  <iframe src="ms.html" class="msbox" name="tag" marginwidth=0 allowtransparency="true" marginheight=0 hspace=0 vspace=0

frameborder=0 scrolling="no" onload="SetWinHeight(this)"></iframe>
