JavaScript

Hey guys for a while now I have been trying to come up with a method that can filter PHP results for listing items using JS.

Look at these examples:

http://www.autotrader.co.uk/search/used/cars/

http://www.vcars.co.uk/used-cars/

You will notice that the actual filter uses JavaScript however my question is how does it query the database to bring back the results?

It obviously using PHP however how does the JS control what the PHP drags from the DB?

Thanks
