Another question - validating user input in fields
Hi, I have another question for you guys. Say, a user types an input into the form, but with my checkings, I made that kind of input, say $%#RG, invalid. But I would like to write a line at the side of the form saying input must be from A-Z or a-z. I think in asp, its called text validators or something. How do you do that in JSP?

RE : Another question - validating user input in fields
Hi, If you want to do it on the client-side, you will need JavaScript to check what the user typed, and then alert some message to tell him that his entries are wrong. On the server-side, you can use the request.getParameter(myParam) to check what the user typed, then send the appropriate response to the client. Hope it helps.

You'll have to handle it yourself. You could do it server-side or client-side with Javascript and DHTML. - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]

Well, if you use Struts, you can use the Validator framework. Everything is almost automatic, with no coding required.
