I just learned some basic AJAX last week. ^^; The reason why I learn AJAX is that I need to help my friend with some of her AJAX coding. Actually, I wanted to learn AJAX long time ago since it is a pretty interesting technique. But I’m just too lazy to pick it up. ^^; Because of that, I decided to go through the short introduction of AJAX at W3Schools. I find that the tutorial there is quite easy to understand and I think beginner should be able to pick it up quite easily. But you need to know JavaScript and server side programming (ie: PHP) before going through the tutorial since it is needed in AJAX. Happy learning!
