            var chars = "0123456789";
            var string_length = 1;
            var randomstring = '';
            for (var i = 0; i < string_length; i++) {
                var rnum = Math.floor(Math.random() * chars.length);
                randomstring += chars.substring(rnum, rnum + 1);
            }
            alert(randomstring); //alert will show the random number
        } 

//setInterval call randomString() function in every 2 second

SB = setInterval(function() { randomString(); }, 2000);
