One of these two should do it for you. I used the first one, although someone on SO told me the second one will work also. I went for the hammer.

Sorry, first one wasn't a cut and paste answer. I use using it to return up/down arrow control on a website. I changed it so that it identifies keycode 13 instead. 

(function() {
    function keykiller(event) {
        if (event.keyCode == 13 )       
        {
            event.cancelBubble = true;
            event.stopPropagation();            
            return false;
        }
    }

    window.addEventListener('keypress', keykiller, true);
    window.addEventListener('keydown', keykiller, true);
})();

Without a library, use: http://jsfiddle.net/4FBJV/1/.

document.addEventListener('keypress', function(e) {
    if(e.keyCode === 13) {
        alert('Enter pressed');
        return false;
    }
});

Searching quickly on SO:

Code from there: 

 var code = (e.keyCode ? e.keyCode : e.which);
 if(code == 13) { //Enter keycode
 //Do something
 }
