[JavaScript] getting position

[Laurent Muchacho]

Hi Chris,

Yes it will work even nested into an other element in IE.
If you interested in NS I never tested it. But I guessed if you want to get
an element who is nested you must do something like that
document.layers['parentid'].document.layers['yourid']
<div id="parented" name="parented">
	<div id="yourid" name="yourid">whatever</div>
</div>

I usually use this function like this.
I have an image somewhere in my html with a name and an id when the document
load I get the left and top of this images and position my div on top of it
or related to it.

the ticker is positioned like this in this page

Regards 

Laurent

Does this take into consideration if it's nested within other elements?
