AJAX is one of those things that every webmaster needs to know about. In today’s e-commerce world, every move toward making a site easier to navigate and interact with is a big plus, and using AJAX is one method of doing just that.
The beauty of AJAX is that it allows a user to do things without requiring the entire page to reload. This makes it a powerful way of improving the speed and functionality of your site. But, perhaps more importantly, it makes your site seem more professional. As end-users, we are so used to seeing interactivity cause page refreshes that whenever we interact with a page and it doesn’t refresh, that by itself can make it feel professional.
And yet, strangely enough, AJAX is not some complicated new technology. It’s just a new way of processing information, and its power, though perhaps more psychological than anything else (saving page loads isn’t that big a deal, when you stop and think about it) is sufficient to make it a staple of all the new web 2.0 technologies.
