use ajax to update a database

[svgmx5]

can anyone help me figure out how i can update a database with out refreshing the page?

 

I know i have use ajax to communicate with the php script that updates the database. But i'm not sure how.

 

I want the database to just update the count every 2 seconds, and echo the counter as well.

 

So basically i have a page with a counter that displays t he number of counts that are stored in the database. And every 2 seconds the database

is updated using ajax and the counter is displayed as well...can anyone help me out? i've looked online for several tutorials, scripts and i can't find much.

Ajax is simple using a library like jQuery.

i got most of that down, but what i'm having problems with is refreshing the page every 2 seconds. i have no clue on how or where to start at.

window.setInterval(function() {
    // ajax call in here.
}, 2000);
