Buttons to play Audio in Mechanical Turk

We would like to integrate audio in an Amazon Mechanical Turk HIT, with buttons to play and increase or decrease volume.

<audio id="player" src="test.mp3"></audio> 
<button onclick="document.getElementById('player').play()">Play</button> 
<button onclick="document.getElementById('player').volume += 0.1">Vol+ </button>  
<button onclick="document.getElementById('player').volume -= 0.1">Vol- </button>

The problem is that any button press is also interpreted as a Submit and the HIT is submitted. How can that be avoided?

Uh, it seems like this is just being caused by a lack of understanding of the HTML <button> tag, not anything to do with Mechanical Turk.

All buttons submit a form by default unless they have the attribute type="button".

This is because, according to the HTML 4.01 specification, the default button type is submit.
