ajax javascript jquery

Hello everybody,

I'm sure this is not the right place to post this. It's just that I'm not sure where to post it and I'm about to pull whats left of my hair out messing with this ajax stuff. I have an idea for a niche website and am working to develop it. I want to throw in some ajax and jquery in order to enhance the user experience. So I'm trying to learn how to do things with ajax.
