Is there a trustworthy way to detect mouse clicks on the native
scrollbar arrow buttons (scrolluparrow and scrolldownarrow) in Mozilla?
Why?
Having a scrollable table i want to fetch more data from server and
append it as table rows if the scrolling is at the end position and i
press again on scrolldown. Without trying my intuition tells me that
onscroll isnt gonna work as there is nothing to scroll down at the end
of scrollable area.
