At the moment I making an ajax based file manager system. Im approched by a tricky problem. As in windows explorer etc I want users to be able to select any free space, click down, and drag a semi-transparent box around that will automaticly select any file/folder elements it covers over.
In a more general sense, take this tutorial page with the three movable objects. I can lift Item 1 and place it over Item 2. But can I use javascript now, so that it automaticly triggers a function because Item 2 is covering Item 1.
So basiccaly Im wondering is there any way to determine if one <div> is covering another?? Cheers for any ideas!
