Form validation is of vital importance to a website’s security as well as its usability. The validation process evaluates whether the input value is in the correct format before submitting it. For example, if we have an input field for an email address, the value must certainly contain a valid email address; it should start with a letter or a number, followed by the @ symbol, and then end with a domain name.
The HTML5 specification has made validation that bit easier with the introduction of new input types such as email, url, and tel, and these also come packaged up with predefined validation. Whenever the value given is not met with the expected formatting, these input types will throw an error message, thus preventing submission.
Expecting every possible input scenario to be catered for is impractical, however. What if you have a username, zip code, or any special data types that are not specified as standard input types? How do we validate those inputs? This is where the attribute pattern comes into play. Learn how to use it in this step-by-step video.
