In the following code:

$(document).keypress(function(e) {

        var code = (e.keyCode ? e.keyCode : e.which);

        if (code == 40) {

            alert(down pressed);

        } else if (code == 38) {

            alert(up pressed);

        }

    });

I'm trying to detect if the down key or up key is pressed. Why isn't it working?
