Topic: quickjump without Javascript
To remove the Javascript, first backup your board, just in case. Then open includes/cache.php for editing. Search for "onchange" (it'll be near the end of the file). When you find it, delete this section:
onchange="window.location=(\'viewforum.php?id=\'+this.options[this.selectedIndex].value)"
Save your changes. Delete all cache_quickjump_*.php files and let PunBB regenerate them, or you won't see any change.
The Javascript affects accessibility because it fires when the selection is changed. Someone navigating by keyboard (like I do when my mouse putzes out) would be unable to immediately access certain forums. For example, I would be unable to select the forum three slots above the current forum, because as soon as I arrowed up once, the script would activate and take me to the forum one slot above me -- not where I wanted to go. This sucks, so I took out the Javascript on my forum using the above method.
