Calculate element-position

Question

I would like to calculate the vertical position of a <div> with jQuery.

How would I do this?

Here's an illustration describing what I mean:

Answer 1

I think you're looking for its offset from the top of the page, right?

$('#div').scrollTop();

If that's not it, maybe the offset would work:

$('#div').offset().top;

Okay, now that it needs to be relative to the parent, try this:

$('#div').position().top;
