getting incorrect offsetleft and offsettop values in IE

[rohitchawla]

have a problem with this code when working in IE
it gives me 0,0 coords when i use iframe tag but gives correct coords when using firefox

[CODE=javascript]function GetRealOffset(i d)
{

var elem = document.getEle mentById(id);
var leftOffset = elem.offsetLeft ;
var topOffset = elem.offsetTop;
var parent = elem.offsetPare nt;

while(parent != document.body)
{
leftOffset += parent.offsetLe ft;
topOffset += parent.offsetTo p;
parent = parent.offsetPa rent;
}
var Offsets = new Object();
Offsets.top = topOffset;
Offsets.left = leftOffset;

alert(Offsets.t op + " " +Offsets.left)
return Offsets;
}[/CODE]

i found out some more function and they r all giving me 0,0 coords
i read in a tutorial that IE gives 0,0 coords for all elements unless the page is loaded but i want the offset values when the page is loading coz im putting advertisements in the iframes and some pages can take minutes to load.
All these functions r working fine in mozilla tho
i think what i need it a function to get the correct offset values when the page is loading in IE

Heya, rohitchawla. Welcome to TSDN!

Don't check against document.body, check against whether or not the offsetParent is null or not. The highest element has a null (non-existant) offsetParent.
