Adding $username to form.

Question

So I went ahead and added the username to the code so that it was required in order for the submit button to be active like Andrew suggested.  Here's my code snapshot. https://w.trhou.se/l8h0omjsdm I am starting to feel like all this is making sense so I am pretty happy with myself.  If I can make it better or add something to it please let me know (or if it doesn't work ._.; ).  I am really enjoying this experience.
Edit: I posted this before I realized that the quiz at the end asked me to do the same thing.  My code is a little different though so is it better to do it as the quiz suggested or is how I have it fine?

The way you have it would technically allow the form to submit, but according to the challenge you would need to verify that the length of the username is greater than 0 using ".length > 0" the same way the password function is doing with ".length > 8". 
In both cases the user could just type in a blank space for the username and that would allow the form to submit. Its not required but if you want one way to make it better you can verify that the username is actual text and not just a bunch of spaces. There are multiple ways  to do that but one way would be to use the $.trim() function. It removes empty spaces from the beginning and end of a string. 
```javascript
var goodName = $.trim("       Marlinda       ");
// goodName equals "Marlinda"
var badName = $.trim("            ");
//badName equals ""
```
