check duplicate user after leave field

Hello, in some forums and websites I see a registration page that check if username exist after press tab or select another field. I know this use ajax to send data before the form is post. I can follow some guidelines to do this ?

This isn't really a supported feature. A simple outline of what you would have to do is have a function that queries the username to check if it is valid or not and call this on the focusout event. Then if the name is taken display the error message.
