jQuery Event Keypress: Which key was pressed?

Question

With jQuery, how do I find out which key was pressed when I bind to the keypress event?

$(\'#searchbox input\').bind(\'keypress\', function(e) {});

var event2key = {'97':'a', '98':'b', '99':'c', '100':'d', '101':'e', '102':'f', '103':'g', '104':'h', '105':'i', '106':'j', '107':'k', '108':'l', '109':'m', '110':'n', '111':'o', '112':'p', '113':'q', '114':'r', '115':'s', '116':'t', '117':'u', '118':'v', '119':'w', '120':'x', '121':'y', '122':'z', '37':'left', '39':'right', '38':'up', '40':'down', '13':'enter'};

var documentKeys = function(event) {
    console.log(event.type, event.which, event.keyCode);

    var keycode = event.which || event.keyCode; // par exemple : 112
    var myKey = event2key[keycode]; // par exemple : 'p'

    switch (myKey) {
        case 'a':
            $('div').css({
                left: '+=50'
            });
            break;
        case 'z':
            $('div').css({
                left: '-=50'
            });
            break;
        default:
            //console.log('keycode', keycode);
    }
};

$(document).on('keydown keyup keypress', documentKeys);
