I need to validate a Text box using javascript
Id like to do it on keypress so that if a user enters a character they shouldnt, it displays a message.
The only characters that should be allowed are A-Z 0-9 and all punctuation
Im trying to do this to avoid people entering foreign characters such as Ĉ è æ
Should I do this using a regular expression?
Whats the easiest way to do this?
