Javascript and Style coordinates Question

[Lars Netzel]

I have a little <Div> following the Mousecursor on mousemove event of
page...

refObject.style.top = event.y
refObject.style.left = event.x

It works fine... BUT when there's a lot more on the page (a growing
Datagrid) which make page need to scroll and you scroll down... the
coordinates does not match the mouscursor anymore since the Top value is not
getting as big as it needs from the event.y property

So how do I calculate how much I have to add to the top style value or can I
somehow convert the event.y to the actualy value from the Top of the page?

best Regards/

Give this a shot:
document.body.scrollTop + event.y;
If you are using flow layout, you may want to try this:
document.body.scrollTop + event.clientY;

Yes, thank you! I did get that tip before you wrote this but it was the
solution that worked. Thank you!
