It’s time to make Break Neck an even better place for ordering pizza. Look
in the chapter05/breakneck/ folder in the book’s examples, and you’ll
nd the latest version of the Break Neck app, complete with HTML, CSS,
and PHP. You’ll need to open up pizza.html, and change the form to run
submitOrder() when “Order Pizza” is clicked, instead of submitting directly
to the placeOrder.php script on the Break Neck server.
As long as you’re making improvements to Break Neck, go ahead and move
all of the JavaScript out of pizza.html. You can use ajax.js, which
you wrote in Chapter 3, for creating the request object. Then, create a
new JavaScript le called pizza.js. Move your Break Neck functions—
getCustomerInfo(), updatePage(), and submitOrder()—into
this le. Don’t forget to add <script> elements that link to these les in your
HTML!
Once you’ve done all of this, ip to the back of this chapter, and check page
314 to make sure your les look the same as ours do. Once you’ve got that done,

You’re moving along pretty quickly now! Let’s get our old pal Frank to update
his PHP script. It doesn’t need to send us back a bunch of HTML anymore.
