offsetLeft Firefox Problems

[eddy556]

I have a problem with the offsetLeft function in Firefox, it gives out different numbers than in IE.  After a bit of research I have found out that this is very well known however I have yet to find a proper solution.

 

This is my code (works in IE), is there any way this could be converted to work in both?

 

function findPos(obj) 
{
    
    var curleft = curtop = 0;

    if (obj.offsetParent)
    {
        curleft = obj.offsetLeft;
       
        curtop = obj.offsetTop;

        while (obj = obj.offsetParent)
        {
        curleft += obj.offsetLeft;
        curtop += obj.offsetTop;
        }
    }
       
    return [curleft,curtop];
}
