309353 - onScroll event doesn't fire for most situations

Status: RESOLVED DUPLICATE of bug 189308

(Firefox :: General, defect)

Description

[David Schontzler]

User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6
Build Identifier: Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US; rv:1.7.10) Gecko/20050716 Firefox/1.0.6

When you attempt to listen on the window or document object's onScroll event,
the event is only fired if the user scrolls by clicking in the scrollbar
(arrows, dragging the scrollbar, clicking between arrow and bar). Events are
*not fired* in the following situations:
- page up/down
- arrow up/down left/right
- home/end
- scrollwheel

Reproducible: Always

Steps to Reproduce:
1. Create a page with lots o' content and an onscroll listener that alerts (or
notifies you somehow)
2. Scroll as many ways as you know how.
3. Notice that you only get the event fired when you are playing with the
scrollbar directly.



Expected Results:  
You'd expect the event to be fired whenever you scroll a page regardless of the
means of scrolling. I think that firing the event on scrollwheel movement is
especially critical as it seems to be the way that folks use to scroll through
content these days.

Please test with a nightly trunk build. This should be fixed in current trunk
builds:
