You could also check to see if the keycode is in a range. See the table below. With a quick search, I found a javascript that will check it. codes 48-57 are numbers 0-9, codes 65-90 are upper letters A-B, codes 97-122 are lower letters a-z.

If you want to allow only characters and digits, you need not know keycodes of all the special characters. Just compare the characters' and digits' ASCII values with the character entered on OnKeyUp event. If it's a special character, just drop it. You can also use java.util.regex.Pattern and java.util.regex.Matcherclasses at server side. -----Original Message----- From: Medicherla Lakshmi [mailto:[EMAIL PROTECTED] Sent: Tuesday, June 27, 2006 2:29 PM To: Struts Users Mailing List Subject: Javascript problem, how to control special characters from being entered into textbox Hi, I hava a javascript problem.
