I got a chance to mess around with some of these techniques recently on my final project for my current employer. Even something as simple as a User Account Request form benefitted greatly from the implementation of this technology. When a user requests an account, if the username they’ve selected is already taken, they are notified as soon as their cursor moves out of the Username field. No submit required.
This new movement towards Ajax technologies and the excitement surrounding the implementations mentioned above have sparked a bit of a rennaissance in the web development field, at least in terms of the excitement some of us are feeling towards the future of web application development. Hello, Web 2.0!
Some Ajax Links:
Jason Fried warns developers to not forget the users in all the excitement over the technology
Drew McLellan walks us through an Ajax script (I should note that this is where I drew inspiration for my User Account Request page)
Apple’s Developer Connection on Dynamic HTML and XML
And, why not Google Search results for XMLHttpRequest
And if this all sounds somehow familiar, let’s call it DHTML ’05
