147865 - Unable to cancel onkeydown event when backspace is pressed

Status: RESOLVED DUPLICATE of bug 167145

(Core :: DOM: Events, defect, P4)

Description

[Phil Anderson]

I'm not sure if this is a bug or not, as I couldn't find the relevent
documentation in the DOM reference, but in recent builds of Mozlla (or at least
in RC3) preventDefault will not cancel the backspace button being pressed from a
onkeydown event.  Even if preventDefault is called, the previous page is loaded.

Just found that the DOM 3 Event spec says that onkeydown and onkeyup are cancelable
http://www.w3.org/TR/2002/WD-DOM-Level-3-Events-20020208/events.html#Events-eventgroupings

->navigator (assuming the binding doesn't honour preventDefault as it should,
although it could be a even problem)

Comment 3

I've tried this in Mozilla 0.9.8 with win95, and the problem also occurs.  I 
havn't been able to reproduce it under linux.  In my build of mozilla (Redhat 
7.3's 0.9.9 build), the backspace key doesn't do anything anyway.
