I've used ajax validation successfully in one case: the user is signing up with a unique username, but form has several/many additional fields as well.
On change of the username field only, do an ajax call check against the database to see if the username or email they entered is unique. If yes, show a "must reenter" message; if not, show a "username ok" message and they continue along the form. Of course you want to back it up with server-side validation as well, but it offers a good experience for the user; they don't have to fill out the whole form before finding out if they've entered a unique username or not. -- Josh ----- Original Message ----- From: "Claude Schneegans" <[EMAIL PROTECTED]> To: "CF-Talk" <[EMAIL PROTECTED]> Sent: Saturday, April 14, 2007 3:25 PM Subject: Re: Client-side validation or Server-side Validation? > >>and using Ajax to send the form data over to a CF page for > validation, but I couldn't get everything to work correctly. > > I'm not sure it's a good approach.
