Jquery will be best suited for this. Demo here

function hideLabel(element) {
        var name = $(element).attr("class");
        var lab = $("." + name)[0];
        $(lab).hide();

    }

    function showLabel(element) {
        var name = $(element).attr("class");
        var lab = $("." + name)[0];
        $(lab).show();
    }
