想框架自动适应内页的高度吗?用这行代码吧!

<script type="text/javascript">
var iframeids=["test"]
var iframehide="yes"
function dyniframesize()
{
  var dyniframe=new Array()
  for (i=0; i<iframeids.length; i++)
  {
   if (document.getElementById)
   {
    dyniframe[dyniframe.length] = document.getElementById(iframeids[i]);
    if (dyniframe[i] && !window.opera)
    {
     dyniframe[i].style.display="block"
     if (dyniframe[i].contentDocument && dyniframe[i].contentDocument.body.offsetHeight)
      dyniframe[i].height = dyniframe[i].contentDocument.body.offsetHeight;
     else if (dyniframe[i].Document && dyniframe[i].Document.body.scrollHeight)
      dyniframe[i].height = dyniframe[i].Document.body.scrollHeight;
    }
   }
   if ((document.all || document.getElementById) && iframehide=="no")
   {
    var tempobj=document.all? document.all[iframeids[i]] : document.getElementById(iframeids[i])
    tempobj.style.display="block"
   }
  }
}

if (window.addEventListener)
window.addEventListener("load", dyniframesize, false)
else if (window.attachEvent)
window.attachEvent("onload", dyniframesize)
else
window.onload=dyniframesize
</script>
