Ajax: Pragmatic Ajax
Gehtland, Galbraith, Almaer, Pragmatic Ajax:
A web 2.0 primer, The Pragmatic Programmers
You've probably heard Ajax mentioned before, and you might
even be sick of hearing about Web 2.0 already seeing as how
mentions seem to mostly come from marketing people and telcos.
Ajax is interesting in its own right though. The visable
idea is that sections of a web page can be loaded without the
whole page needing to be reloaded. This has been doable for
ages by preloading material and using divs in HTML but the
killer addition with Ajax is the ability to get material on
the fly without preloading. The poster-app for this has been
Google maps even though it wasn't actually done in Ajax.
This book takes you through what it's all about and starts
off with a Google Maps-like app. It goes to look at different
aspects of Ajax including the DOM model and using it in conjunction
with the likes of PHP. It also looks at libraries and they
are springing up all over the place with the latest being Spry
from Adobe. Libraries will be the way that most people use
Ajax but a knowledge and understanding of the foundations will
serve those that want to be ahead of the curve
