Well remember, if the user is submitting data(which they probably are) to be processed by something on the server then it's not a good idea to rely on server side prevention. What I'm saying is if you're using it in an sql query or something then the user can easily tweak the html or just replicate the post form and take out the # characters limit. Best way is to check if it's >25 on the server.
Oh, and here's a link on how to limit # of characters in JS, so the user doesn't have to submit to learn it's the wrong length. http://www.felgall.com/jstip20.htm On 6/11/07, Tobias Koller (GERMO GmbH) <[EMAIL PROTECTED]> wrote: > The events "keyinput" or "keypress" are better than "keydown" I think ;) > But I don't know if there's a way to manipulate the pressed key. > > Tobias > > -----Ursprüngliche Nachricht----- > Von: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] Im Auftrag von Tobias Koller > (GERMO GmbH) > Gesendet: Montag, 11.
