Peachpit Press Visual QuickStart Guide jQuery
jQuery is an open-source JavaScript kit for
building Web applications so dynamic they
jump off the page. Filled with special controls
like calendars and tab folders, and special
effects like wipes and fade-ins, jQuery is gain-
ing popularity rapidly.
Perhaps most important, jQuery gives you
excellent support for Ajax applications. Ajax
is what allows you to access a Web server
from a browser without a page refresh—that
is, there’s no blinking, no flicker when you
download data behind the scenes with Ajax;
you just download the data and then you can
display it in a Web page using dynamic HTML
techniques. No fuss no muss—and the end
result is an application that looks more like a
desktop application than a Web application.
With Ajax, the user can do something in a
browser page, and the result of their action
appears instantly, updated immediately in
the browser window, without affecting the
other contents of the window.
