js日期时间补零的小例子

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();
