Year= day.getfullyear ()//ie Firefox can be Month= day.getmonth () +1; Day = Day.getdate (); Hour = Day.gethours (); Minute = Day.getminutes (); Second = Day.getseconds (); currentdate = year; if (Month >= 10) { currentdate + = Month; } Else { currentdate + = "0" + Month; } if (Day >= 10) { currentdate = day; } Else { currentdate + = "0" + day; } currentdate = currentdate + Hour + Minute + Second + num; document.getElementById ("FName"). Value=currentdate; } Function Getrandomnum (min,max) {       var Range = max-min;        var Rand = math.random ();       return (Min + math.round (Rand * Range));  & nbsp }   </script>
