Break Neck doesn’t seem to be asking for anything that complicated. Let’s see if we

can convert the Break Neck pizza form submission into an asynchronous request.

Here’s what you’ll need to do:

Submitting a form with Ajax

submitOrder()

showConrmation()

Your new JavaScript function, submitOrder(),

will submit the customer’s order to the

Break Neck server asynchronously, using the

information in the pizza order form.

In this step, you’ll have to write

a new callback function. This

will need to take the delivery

time that you get from the

Break Neck server, and give the

customer a conrmation that her

order is on its way.

First, you’ll need to change the Break Neck

HTML: instead of letting a customer place

her order with a submit button, the “Order

Pizza” button should call a new JavaScript

function. You’ll write this function in the

next step, and call it submitOrder().

You’ll have to make sure the

PHP script on Break Neck’s

server doesn’t send back

HTML anymore... instead, it

should return how much time

it will take for the pizza to

arrive at the customer’s door.
