Find iframe element absolute coordinates

[dema rogatkin]

I have a small iframe with elements when I move mouse over I want to see status popup fed by Ajax. It works fine, however popup div defined in iframe can't overlap parent window and gets clipped out. For this reason I moved it in a main window. Now I have to figure main window coordinates of popup which will be shown by side of an iframe element. I tried iframe.offsetTop and iframe.offsetLeft added to element coordinates, however they are always 0. I found work around using coordinates of an element where iframe inserted in, but it won't be always the case. So, how I can find absolute coordinates of iframe? Sorry for a beginner question.

basic idea:

function GetElementPostion(xElement){
 
  var selectedPosX = 0;
  var selectedPosY = 0;
  var theElement = document.getElementById(xElement);
              
  while(theElement != null){
    selectedPosX += theElement.offsetLeft;
    selectedPosY += theElement.offsetTop;
    theElement = theElement.offsetParent;
  }
                                    
  alert(selectedPosX);
  alert(selectedPosY);
 
}

Hello I have a problem related to this.

I have the following iframe:

  <iframe id="myContent" src="http://localhost/test.html" width=300 height=600 hspace=0 vspace=0 frameborder=0 marginheight=0 marginwidth=0 scrolling=no style="visibility: hidden" ></iframe>  

this iframe tag is enclosed with <td> tags and I would like to extract the location and coordinates of the iframe. I happened to have a very similar function that does this:

function getCurrTop(name) {
obj = document.getElementById(name);
y = 0;
while(obj) {
y += obj.offsetTop;
obj = obj.offsetParent;
}
return y;
}    

So, to get the top location of my iframe, i make a call:

getCurrTop("myContent");

This works perfectly fine in firefox, but returns 0 in internet explorer... any idea why? Thanks in advance for your help.
