This is called client-side form validationand helps ensure data submitted matches the requirements set forth in the various form controls. This article leads you through basic concepts and examples of client-side form validation. Client-side validation is an initial check and an important feature of good user experience; by catching invalid data on the client-side, the user can fix it straight away.

If it gets to the server and is then rejected, a noticeable delay is caused by a round trip to the server and then back to the client-side to tell the user to fix their data. However, client-side validation should not be considered an exhaustive security measure! Your apps should always perform security checks on any form-submitted data on the server-side as well as the client-side, because client-side validation is too easy to turn off, so malicious users can still easily send bad data through to your server.

Read Website security for an idea of what could happen; implementing server-side validation is somewhat beyond the scope of this module, but you should bear it in mind.

Even if your form is validating correctly and preventing malformed input on the client-side, a malicious user can still alter the network request. One of the most significant features of HTML5 form controls is the ability to validate most user data without relying on JavaScript.

This is done by using validation attributes on form elements. We've seen many of these earlier in the course, but to recap:. If not, it is considered invalid.
