[jQuery] how can 'load on scroll' be achieved in jquery+php


Hi
I finally came across a site that demonstrates how to achieve this in
CF and Java script. But i dont know CF at all so I'm unable to pick
exactly what is going on.
Can some one help me explaining this code and converting it to jquery
plugin?
