js日期时间补零

function getNowFormatDate()
        {
           var day = new Date();
           var Year = 0;
           var Month = 0;
           var Day = 0;
           var CurrentDate = "";
           //初始化时间
           //Year       = day.getYear();//有火狐下2008年显示108的bug
           Year       = day.getFullYear();//ie火狐下都可以
           Month      = day.getMonth()+1;
           Day        = day.getDate();
           CurrentDate += Year + "-";
           if (Month >= 10 )
           {
            CurrentDate += Month + "-";
           }
           else
           {
            CurrentDate += "0" + Month + "-";
           }
           if (Day >= 10 )
           {
            CurrentDate += Day ;
           }
           else
           {
            CurrentDate += "0" + Day ;
           }

           return CurrentDate;
        }


//获取的时间就会补零
var nowdate = getNowFormatDate();
