There seems to be a bit of debug code left in your sample above, below is a slightly modified version that works for me.

I’ve also added support for object padding, which also causes the co-ordinates to be off.

Finally, i found that an object may not be set to position=relative, so I changed the logic to be != absolute.

/**
* Returns the absolute X and Y positions of an object.
* @param {HTMLObject} obj HTML Object.
* @return {Object} Returns an accessor with .x and .y values.
*/
function getXY(obj)
{
var curleft = 0;
var curtop = 0;
var border;
var padding;
if (obj.offsetParent)
{
do
{
// XXX: If the element is position: relative we have to add borderWidth
if (getStyle(obj, ‘position’) != ‘absolute’)
{
if (border = getStyle(obj, ‘border-top-width’)) curtop += parseInt(border);
if (border = getStyle(obj, ‘border-left-width’)) curleft += parseInt(border);

if (padding = getStyle(obj, ‘padding-top’)) curtop += parseInt(padding);
if (padding = getStyle(obj, ‘padding-left’)) curleft += parseInt(padding);
}
curleft += obj.offsetLeft;
curtop += obj.offsetTop;
}
while (obj = obj.offsetParent)
}
else if (obj.x)
{
curleft += obj.x;
curtop += obj.y;
}
return {’x': curleft, ‘y’: curtop};
}
