To understand the benefits of AJAX, consider a
renovation scenario. You’ve decided you want
a stained glass window beside the front door.
The renovator removes the existing plain glass
and window frame, takes it to the shop for
replacement with the stained glass, and returns
to reinstall it. He obviously has no need to
touch the other windows or — to be completely
ridiculous — tear down the house and replace
everything in the process.
The same concept applies to a Web page. If you
just want to change the content in one area of the
page, you don’t need to wipe out the existing page
and ask the server to resend all the images and
HTML markup. AJAX works like the renovator,
doing just what’s required but not more.
