Welcome to TSDN!

You can validate at the time the data is entered in the form input field or validate all input data in in a form before sending off the content to a server.

For the first option I refer to Javascript tutorial Form at http://www.tizag.com/javascriptT/javascriptform.php

For the second, see article Form Validation, to be found at the W3Schools website at http://www.w3schools.com/js/js_form_validation.asp

Hope this will help to get it more clear.
