Learning Joomla! 1.5 Extension Development is a new book from Packt that helps users to program their own Joomla! extensions. Written by Joseph LeBlanc, and tested against the final release of Joomla! 1.5, this book helps create extensions with PHP using built-in HTML and JavaScript functions. Joomla! is ready for your modern JavaScript needs. By using the MooTools JavaScript framework, you can find elements and assign event handlers to them. You can also
use pre-built functions within Joomla! to generate the JavaScript necessary for many typical effects. Regardless of the number of effects used, Joomla! will make sure that
the MooTools framework is only loaded once, as long as you use the JHTML member functions.
