In Detail
JavaScript: It's not just for calculators and image rollovers.
Drupal 6 is loaded with new features, and not all of them are necessarily implemented in PHP. This unique book, for web designers and developers, will take you through what can be done with JavaScript (and especially with jQuery) in Drupal 6.
With the combination of the powerhouse jQuery library with its own robust set of JavaScript tools, Drupal 6 comes with a pre-packaged killer JavaScript environment. Cross-platform by nature, it provides all of the tools necessary to create powerful AJAX-enabled scripts, gorgeous visual effects, and view-enhancing behaviors. In addition, Drupal developers have ported some of its most powerful PHP tools - like a theming engine and support for localization and language translation - to JavaScript, making it possible to write simple scripts where once only complex PHP code could be used.
This book gives you the keys to the toolbox, showing you how to use Drupal's JavaScript libraries to make your modules and themes more dynamic, interactive and responsive, and add effects to make your Drupal site explode into life!
If you've dipped your toe in the water of theme or module development with Drupal 6, this is the book you want to make the look and behavior of your work something special. With it's project-based approach, this book is carefully constructed to guide you from how JavaScript fits into the overall Drupal architecture through to making you a master of the jQuery library in the world of Drupal themes and modules.
