      var curTime = Date.now();
      var endTime = new Date("2017-10-26 16:00:00");
      var allFreeSeconds = (endTime-curTime)/1000;
      if(allFreeSeconds>0){
        var freeDay = Math.floor(allFreeSeconds/(24*60*60));
        var freeHour = Math.floor(allFreeSeconds/(60*60) % 24);
        var freeMinute = Math.floor(allFreeSeconds/60 % 60);
        var freeSecond = Math.floor(allFreeSeconds%60);
        document.getElementById("nowTime").innerHTML = "剩余"+freeDay+"天"+freeHour+"时"+freeMinute+"分"+freeSecond+"秒";
      }
      else{
        document.getElementById("nowTime").innerHTML = "已结束";
