HTML Form / jQuery (beginner) Help

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?

(first post - not really sure how to share code on here yet) https://w.trhou.se/3ey4i04g13

Hey 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
