next generation applications
It’s time to see what all this hard work has done for Katie’s web report.
Make sure you’ve added all the JavaScript we’ve talked about in this
chapter, and double-check that the “Show Me the Money” button runs
getBoardsSold(), instead of submitting the form. Then, load up
boards.html in your web browser, and let’s see what Ajax can do!
Showing Katie some Ajax magic
Click on “Show Me
the Money”...
...and there’s no page
reload. Perfect!
Both the total
boards sold and
the cash Katie’s
made got updated.
Check it out for yourself!
That’s perfect!

Chapter 1
You did it! You took a boring
sales report, and turned it
into a dynamic Ajax application!
Nice work. Katie’s web report is back online,
Katie knows how much cash she’s making—
without having to wait on her server or suffer
a bunch of page reloads—and with all that
prot, Katie’s even offered to give you free
snowboarding lessons.
Reviewing the highlight reel
Asynchronous applications make requests
using a JavaScript object, and not a form
Your requests and responses are handled
by the web browser, not directly by
your JavaScript code.
Once the web browser gets a response to
your asynchronous request, it will “call back”
your JavaScript with the server’s response.
