Stop form from refreshing but do post

I am working on a radio website, with a player, and a bunch of banners where you can click on to play a radio.

The ideal behavior in my opinion would be that if i click on the button to play a radio, it'll jump to the player. But now its refreshing the page, and jumping to the top of the page. which is a bit annoying.

1. I got an form with multiple buttons, those buttons contain the ID of the radio from the database.


2. Then i got my player, without the form being posted, printing a default player, on submit of the form, it'll load all the information needed from the database with the ID that's being posted to the player.

Now my question is, how to stop the form from refreshing and jumping back to the top of the page, while it does post to the player.

if you guys need any code, i am wiling to post it here, but since it a shitload of code on my index.php i need a site where i can put this on.
