AJAX Hacks

by Bruce W. Perry

AJAX, the popular term for Asynchronous JavaScript and XML, is one of the most important combinations of technologies for Web developers to know these days. With its rich grouping of technologies, AJAX developers can create interactive Web applications with XML-based Web services, using JavaScript in the browser to process the Web server response.

Taking complete advantage of AJAX, however, requires something more than your typical "how-to" book. What it calls for is AJAX Hacks from O'Reilly. This valuable guide provides direct, hands-on solutions that take the mystery out of AJAX's many capabilities. Each hack represents a clever way to accomplish a specific task, saving you countless hours of searching for the right answer.
