Web 2.0 get mouse coordinates

In Web 2.0 I need to get the Y mouse coordinate to position a webtextfield over a Weblistbox.
I appears that Web 2.0 does not have anything related to mouse coords. So maybe someone knows some Javascript magic that will work. I don’t know javascript or even where to put it in my code. Please help.
Thanks

Does anybody has an answer for this? I want to put a text field on top of a cell when I click on a cell of a weblistbox

You can use GraffitiEventManager do to some of the more advanced event tracking such as keys and mouse.

It looks like you made some progress here:

Maybe you can share a sample of your code on a new thread/post with what you did and someone can take a look at what is missing.
