Question

Reload Iframe height

Asked by: brassmon

I am getting the height of my iframe using this code.  It loads the original page correctly but I have a  jumpMenu that loads other pages in the IFrame and when i select a new page it does not resize the IFrame.  If someone could give me some help on this it would be greatly appreciated.

<script language="JavaScript">
function iFrameHeight() {
 if(document.getElementById && !(document.all)) {
  h = document.getElementById('iframename').contentDocument.body.scrollHeight;
  document.getElementById('iframename').style.height = h;
 }
 else if(document.all) {
  h = document.frames('iframename').document.body.scrollHeight;
  document.all.iframename.style.height = h;
 }
 alert(document.iframename.width)
}
</script>
</head>
<body onLoad="iFrameHeight();">
<IFRAME SRC="iframe.html" NAME="iframename" ID="iframename"></IFRAME>

Do any of these allow me to resize the iframe when a link is clicked on and the src in the iframe is changed?  I did not have much luck with any of these.  Please help.  I have not been able to get a solution to this anywhere.
