[jQuery] keyup on textfields

[onaiggac]

Hi,
Im new in jQuery, so...

I need the textfields triggers the same function and I have a lot of
them, Im doing this way:

    $('#id_emp').keyup(function(e) {
        if (e.keyCode == 13) {
            $('#busca').click();
        }
    });

    $('#id_bol').keyup(function(e) {
        if (e.keyCode == 13) {
           $('#busca').click();
        }
    });

    $('#ema_pes').keyup(function(e) {
        if (e.keyCode == 13) {
           $('#busca').click();
        }
    });

    $('#nom_emp').keyup(function(e) {
        if (e.keyCode == 13) {
            $('#busca').click();
        }
    });

But Im think that have a better way to do this, like:

    $('ALL_TEXTFIELDS').keyup(function(e) {
        if (e.keyCode == 13) {
            $('#busca').click();
        }
    });

There's something like this?
