At the end, there's a little exercise to keep you busy too!Form validation is the process of checking that a form has been filled in correctly before it is processed.My goal in writing this is to shed some light on the new APIs to help developers make better web forms for everyone.In this tutorial I will: Per the spec how errors are presented to the user is left up to the browser itself.Great for "required fields" such as email addresses!This tutorial will show you how to create a Java Script-enabled form that checks whether a user has filled in the form correctly before it's sent to the server.
