I wrote an AJAX function awhile back that I use in a lot of my website projects. I use it because I prefer it to using an entire javascript library just to get the AJAX functions out of it. This is incredibly simple and is great for just the basic AJAX applications. Just about anyone with basic web building skills should be able to implement this into their site for some extra jazz.

I put together a simple demo here: Ajax Demo. Check it out for basic usage and to get the javascript source code. You can download the entire demo here: Ajax Demo Source Files. Upload these file to your server and you’ll be able to figure out how this works in no time.
