Table with div submenu

[HDI]

Hi,

I've got a table and when a user moves over a row I want to show a div
with a submenu.

The code is ok but when I move over a row he sets the top and left to
the mousepoitners top and left (event.clientX and event.clientY).

How can I put the div(submenu) to the top of the row and the right
side.

Thx

Hi,

You can use those functions to find the position X and Y on most
browsers of an element:
function findPosX(obj) {
var curleft = 0;
if(obj.offsetParent)
while(1)
{
curleft += obj.offsetLeft;
if(!obj.offsetParent)
break;
obj = obj.offsetParent;
}
else if(obj.x)
curleft += obj.x;
return curleft;
}

function findPosY(obj) {
var curtop = 0;
if(obj.offsetParent)
while(1)
{
curtop += obj.offsetTop;
if(!obj.offsetParent)
break;
obj = obj.offsetParent;
}
else if(obj.y)
curtop += obj.y;
return curtop;
}


obj is the row of the table in your case, and do a simple calculation
to get the most right part of the row.


cheers..

How do I pass that row?

Y = findPosY(???)

The argument of findPosY is the parent item..

something like:
Y = findPosY(document.getElementById('row').firstChild());
