JavaScript Regular Expressions in JavaScript Validating a Form Validating a Username

Benefit of using Javascript over HTML5 form verification

Just wondering if there are any benefits to using the javascript procedures outlined in this and proceeding video's for checking the contents of a form field against a regex when the same process can be done relatively simply using the HTML5 verification steps outlined here.

I'd think the main advantage to validating in JavaScript is if you want something other than the default HTML behaviors. For example, instead of just red borders, you might want explicit helper messages to appear.

Yea, after playing around with the javascript there's a lot more flexibility.

html attributes can easily be deleted from the inspect and pass validation
