I'm trying to make a simple form where the submit button is not enabled until the username is > 5 characters. Any idea why this isn't working?

Courses Plus Student 31 PointsHey Nicholas , I see your code and i found the problem why your code is not working
var $username = $('#username');
var $submit = $('#submit');
function isUsernameValid() {
return $username.val().length > 5;
}
function enableSubmit() {
$submit.prop('disabled', !isUsernameValid());
}
$username.focus(enableSubmit).keyup(enableSubmit);//you need to call the function each time when you focus or releasing key
hope it helps you
