Top left coner of html control

[Shimon Sim]

Is it possible to find top left corner of a control using JavaScript?
As far as I know it is very easy to do if you use Grid layout while
designing a page. But if you are using flow layout I didn't find any method
to find top left corner of a control.

I see drop down calendars that drop right under control even though I
designed page in flow layout.
How do they do it?
Thank,
Shimon.

Generally you'd put both controls into a panel, div, or table cell separated
by a <br> tag.
Here's a more detailed analysis of your options:

Hi Shimon,

For html elements in non-absolute layout html page, we need to use
recursive script function to get their absolute postion on the whole page.
For example:
function getAbsoluteLeft (oNode)
{
var oCurrentNode = oNode;
var iLeft = 0;
while(oNode != null && oCurrentNode.ta gName != "BODY" )
{
iLeft += oCurrentNode.of fsetLeft;
oCurrentNode=oC urrentNode.offs etParent;
}

return iLeft;
}

function getAbsoluteTop( oNode)
{
var oCurrentNode = oNode;
var iTop = 0;
while(oNode != null && oCurrentNode.ta gName != "BODY")
{
iTop += oCurrentNode.of fsetTop;
oCurrentNode = oCurrentNode.of fsetParent;
}
return iTop; }

However, such scripts also depend on the browser's script model support,
I've test the above functions on IE6 and it works. Hope also helps.
