He is doing formatting on the client side in JQuery.
He is registering this function on the page with this:
$(document).ready(function () {
$('#yourphone').usPhoneFormat({
format: '(xxx) xxx-xxxx',
});
});
You could do a similar thing.
In NT rather than a function you'd probably bind this formatting to a class. Meaning, any fields where you want this formatting, add your "format into phone number" class to the html input and add your jquery that looks for this class and applies the formatting.
