Chapter 2

Step 2: Request the customer’s address

Next up is sending the phone number we got in

Step 1 to Break Neck’s web server, and asking for the

customer’s address based on that phone number.

<script>

var request...

function foo()

{

...

}

</script>

JavaScript

Customer’s Phone Number

2. Next, using the phone

number you just got from

the web form, you can set

up a new request with that

phone number as the data

in the request.

1. You’ll need to create a request

object in our JavaScript, just like

you did back in Chapter 1.

4. The Break Neck web server needs a

PHP script that can look up a customer’s

address using his phone number.

Web Server

Man, Break Neck pizza rocks. There’s

nothing like a breakfast of cold pizza, a

whipped latte from Starbuzz, and the

Webville Times to read.

<script>

var request...

function foo()

{

...

}

</script>

JavaScript

<script>

var request...

function foo()

{

...

}

</script>

Customer’s Phone Number

Customer’s Address

Customer’s Order

3. You can use the request object

to send the customer’s phone

number to the Break Neck server.
