You can check the goal yourself:
$(document).on('mousedown', function(e) { console.log(e.target); });
Fiddle
Scrollbar is'nt really an element, and click handlers will not work, but it seems that mousedown has been fired, but will just give you the element that owns the scroll bar.
To exclude only the scrollbar, I assume that you will need to figure out its size and then check the mouse position on mousedown to see if it is in the scrollbar area.
