IFrame自动更改大小

<iframe id="xx" name="xxx" src="http://..." style="dispaly:block;width:100%" scrolling="auto" frameborder="0" onload="javascript:{resize(this);}"></iframe>

<script language="javascript">
fucntion resize(control)
{
   if(control)
  {
    if(isIE)
   {
       control.height=control.Document.body.scrollHeight;
   }
   else
   {
   control.height=control. contentDocument.body. offsetHeight;
    }
  }
}
</script>


注意：经测试，在resize中write:
var getFFVersion=navigator.userAgent.substring(navigator.userAgent.indexOf("Firefox")).split("/")[1];
会使firefox1.0.2崩溃！
