I always wondered what is AJAX all about. So I set about trying to figure it out myself. I needed a project, so I decided to build a web-based WhiteBoard. An online space where users can add sticky notes, move them around, and so on.

You can try it out here. Right now you can just move the notes around, and the position is automatically saved. When you revisit/reload the page, the settings will be retained.

Most of the functionality has not been built as yet, but I’ve figured out how AJAX works.

I have tested this on Google Chrome. Don’t know about the other browsers as yet. Should work fine in the other browsers, but not sure about Internet Explorer.
