How to pass a Javascript variable to a PHP variable without reloading the page

How do you pass a Javascript variable to a PHP variable without reloading the page?

(I am pretty sure this is done through ajax)

 

I am trying to make a simple checkbox in js, and depending on the state of the checkbox, I want the value of the current state of the checkbox to be put into a js variable. After that, I want to send that js variable value to a php variable, and then just echo the value. An example file would be amazing!

 

Thanks a lot,

It is a 3 state checkbox btw . One state when mouse is not over, another when over and then one when clicked(it keeps the state until clicked again), when clicked again it goes back to first state.

There are heaps of simple ajax examples around. I would recommend using a framework though, they make things allot simpler.
