I need to figure out the exact position of an IFrame without setting any stylesheets for it (no id, no position). Normaly this works fine with offsetLeft, but not if the IFrame is created in an table. Here ist the code on which I am working.




<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN">

<html>
<head>
     <title>Untitled</title>
     <SCRIPT language=JavaScript>
     <!--
     function test() {
          document.write('<iframe s'+'rc="http://www.yahoo.com" width=400 height=300 marginwidth=0 ');
          document.write('marginheight=0 hspace=0 vspace=0 frameborder=0 scrolling=no>');
          document.write('</iframe>');
     }
     // -->
     </SCRIPT>
</head>
<body>
<table border=0>
<tr>
     <td>Tested</td>
     <td>
     <script language=javascript>
     <!-- //
     test();
     // -->
     </script>
     </td>
</tr>
</table>
     <script language=javascript>
     for(i = 0; i < top.document.all.length; i++){
          if (top.document.all(i).tagName == "IFRAME") {
          var oElement = top.document.all(i);
              alert(i + ": Left: " + oElement.offsetLeft + ", Top: " + oElement.offsetTop);
          }
     }
     </script>
</body>
</html>

How are these:

function getTop(obj)
     {
     var height=0;
     while ((obj.offsetParent))
          {
               height+=obj.offsetTop;
               obj=obj.offsetParent;
          };
     return height;
     }

function getLeft(obj)
     {
     var left=0;
     while ((obj.offsetParent))
          {
               left+=obj.offsetLeft;
               obj=obj.offsetParent;
          };
     return left;
     }

But for IE 5+ only...i'm pretty sure older IE & NS &c. won't tell you anything about positioning, so you might figure out a way you don't need the info.
