I have a div with an overflow, so it has a scrollbar. The "what are my mouse's coordinates" tutorials (like this one: http://docs.jquery.com/Tutorials:Mouse_Position) only yield A) the coordinates of the mouse on the page (using "e.pageX" and "e.pageY", or B) the absolute coordinates of the mouse, within the element, on the page (using "e.pageX - this.offsetLeft;"). What I want to do is to find out how far down, *within my scrolling element*, the mouse is.
Best way to think of it: picture a calendar, like on Google Calendar. It has a scrollbar, so 10:00 am might be the earliest-visible timeslot (the mouse position would be at 0, 0 if it were in the top-left corner. But within div#calendar, you could have 599 pixels hiding above the visible section. That is, the mouse is actually at point 0, 600. How can I determine how much of the div is hiding? Alternately, how can I determine what the mouse's coordinates are, considering the entire height of the div, and not just the visible portion of it?
