Lots of work has gone into AJAX (formerly AHAH) and Javascript in Drupal 7.
AJAX is WAY easier to use now, and there are lots of new Javascript/JQuery features, including JQuery UI in core. Our goal is that you'll walk out of this session no longer afraid of AJAX in Drupal.
What is AJAX? AJAX was called AHAH just yesterday (D6), and in the Drupal context it most often means the ability for Drupal forms to dynamically refresh without a page load. So it means cooler forms that don't have to press the submit button all the time - they can dynamically respond to user input.
Who is this for? Any developer or themer who knows some PHP and a little Javascript. We'll aim to make the AJAX portion accessible to anybody who has ever seen the Drupal forms API, and the javascript portion should be accessible to anyone who has used or wants to use Javascript in Drupal.
In this talk we'll cover:
