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. First we'll explain why form validation is a useful thing, and then build up a simple example form, explaining things as we go along.

In the next article in this series, I'll show you how to use the native Constraint Validation API to bolt-in our desired UX with some lightweight Java Script.

Shows you how to write a script that ensures your form is filled in correctly before it's sent to your server.
