In the following code, what should go in place of "¿?" to obtain the height of one (any) of the frames?

Code: 
<head>
...
  <script language="javascript">
     var frameheight = ¿?
  </script>
</head>
<frameset rows="30,*,30">
  <frameset cols="30,*,60,*,30">
    <frame name="top1" />
    <frame name="top2" />
    <frame name="top3" />
    <frame name="top4" />
    <frame name="top5" />
  </frameset>
  <frameset cols="30,*,60,*,30">
    <frame name="middle1" />
    <frame name="middle2" />
    <frame name="middle3" />
    <frame name="middle4" />
    <frame name="middle5" />
  </frameset>
  <frameset cols="30,*,60,*,30">
    <frame name="bottom1" />
    <frame name="bottom2" />
    <frame name="bottom3" />
    <frame name="bottom4" />
    <frame name="bottom5" />
  </frameset>
</frameset>

That would be the height of the top-most frame i.e. the browser's window, wouldn't it?

Do you need this to work in all browsers??

I have something that will work in IE6 at the least.

It won't work in FF, and I'm not sure about IE7.

This works in IE6:

Code: 
var fr = top.frames[5]
if (fr.window.innerHeight) {
   height = fr.window.innerHeight
} else if (fr.document.body.clientHeight) {
   height = fr.document.body.clientHeight
}

However, this seems to be the height of the document, not the height of the frame.

In IE6, this will list the heights of each frame on the onload.
Code: 
<script type="text/javascript">
   function doAlert() {
      var framesArray = window.parent.frames;
      var framesArrayLength = framesArray.length;
      for (a = 0; a < framesArrayLength; a++) {
         alert(framesArray[a].document.getElementsByTagName("body")[0].offsetHeight);
      }   
   }   
</script>
</head>
<frameset rows="30,*,30" onload="doAlert()">
  <frameset cols="30,*,60,*,30">
    <frame src="test2.html" name="top1" />
    <frame name="top2" />
    <frame name="top3" />
    <frame name="top4" />
    <frame name="top5" />
  </frameset>
  <frameset cols="30,*,60,*,30">
    <frame name="middle1" />
    <frame name="middle2" />
    <frame name="middle3" />
    <frame name="middle4" />
    <frame name="middle5" />
  </frameset>
  <frameset cols="30,*,60,*,30">
    <frame name="bottom1" />
    <frame name="bottom2" />
    <frame name="bottom3" />
    <frame name="bottom4" />
    <frame name="bottom5" />
  </frameset>
</frameset>
</html>
