Mozillafix für BBCode und Smilies beim Posten

Beitrag von **cYbercOsmOnauT** » 18.09.2006 11:28

Dieses Snippet behebt das Problem, dass die Cursorposition bei Browsern, die die Geckoengine verwenden (z.B. Mozilla, Netscape, Firefox) beim Anklicken von Buttons und Smilies (Postfenster) verloren geht.

Das Snippet wurde aus dem "BBCodes & smilies enhancement" Mod von GolfExpert entnommen. Die Codeteile sind zumeist gecodet von markus_petrux und TerraFrost.
