Description Nick Welch 2003-08-10 22:58:23 UTC

Version:            (using KDE KDE 3.1.2)
Installed from:    Debian testing/unstable Packages
OS:          Linux

The site in question is forums.anandtech.com.  They use some javascript keyboard grabbing for various things, but this nukes pageup/pagedown/home/end/arrows/etc in Konqueror.

The relevant javascript appears to be located at the very bottom of the source of each page, and involves document.onkeydown, window.event.altKey, and window.event.keyCode.  I don't really know any javascript, but I suspect that document.onkeydown is given priority over the built-in Konqueror navigation keybindings.

I did some testing, and this indeed does seem to be the problem.  I have a copy of a page at:

http://incise.org:82/~death/at.html

I made a single change; removing the "document.onkeydown = handleEvent;", and the keyboard functionality returns.  However, I also pasted this javascript into a rather plain page at:

http://incise.org:82/~death/foo.html

And the problem did not occur (keyboard navigation works correctly).  This seems to suggest that the problem is a combination of things.  I'm not sure what the other factors are though.

My mistake, the foo.html above DOES exhibit the same behavior.  I got a little 
feisty with copy/paste in vim and didn't notice that I totally messed up the 
javascript. 
 
So it seems that this narrows the problem down to simply document.onkeydown.

hmm, can't access the testcase.

closing invalid, testcase no longer available.
Please let us know if this is still an issue for you.
