Form Validation

We've already validated forms using HTML5, however older browsers don't support this functionality. Therefore, many web application use javaScript form validation as a fall back measure. You'll need to do this for assessment2!!!

Why validate forms using javaScript

• User input can't be trusted
• javaScript validates the user input before it's sent to the web server
• This makes forms quicker to use as the page does not have to reload for each error
• It also reduces server load
