Tip

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;
   }
  }
 }
}
