<script> getNowFormatDate(); function getNowFormatDate() {     var day = new Date();     var Year = 0;     var Month = 0;     var Day = 0;     var CurrentDate = "";     var num = GetRandomNum(1,10);       //初始化時間     //Year= day.getYear();//有Firefox下2008年顯示108的bug     Year= day.getFullYear();//ieFirefox下都可以     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));   }   </script>
