Scale your Iframes to the size of their content

This tip describes how to scale your Iframes to the size of their content.

This tip will help get rid of scrollbars that appear around Iframe content, allowing you to give a page with multiple iframes the appearance of just one document.

This works for IE5, 5.5 and 6, useful considering the differences between Iframe implementation in 5 and 5.5 & 6.
 

  Code: function fullsizeIFRAME(iframeName) {
 if (document.all[iframeName])
 { // test for existence of frame
  var obj = document.getElementById(iframeName);
  if (obj.contentWindow) { // check 
to see if the browser is IE5.5
   if (obj.contentWindow.document) {
    var doc = obj.contentWindow.document;
    if (doc.body) { // check a document 
isn't being loaded to avoid errors
     obj.height = doc.body.scrollHeight;
    }
   }
  } else if (obj.document) { // IE5.0
   if (frames[iframeName].document.body)
 { // check for transition / refresh
    obj.height = frames[iframeName].
document.body.scrollHeight;
   }
  }
 }
}
