Modify Web pages on the fly

One of the things that Ajax is big on is updating or modifying a Web page as the user watches.

Because Ajax applications avoid complete page refreshes, along with the accompanying flicker and

flash, you must update specific parts of a Web page in the browser. There are thousands of Ajax appli-

cations out there that operate this way, and you’re going to be creating some in this book as well.

Here’s an example already online:

, which you can see in Figure 1.30.

“card” of information appears, as you see in Figure 1.31.
