Ciao a Todos!!

codice:
    function MouseMove() {
            $(document).mousemove(function(e) {
            var percent = e.clientY / $(window).height();
            $('body, html').scrollTop($(document).height() * percent);
            });
    }
    
    function MouseNoMove() {
            $('body, html').unbind(MouseMove)
            alert('chiamata ok');
    }
come faccio nella funzione MouseNoMove a disabilitare MouseMove
