Question

如何在 NativeScript 中使用日期格式实现倒数计时器？

setInterval(() => {

}, 1000);

Answer 1

  getRemainingTime(remainingMillis) {
    setInterval(() => {
      let seconds = Math.floor(remainingMillis / 1000);
      let minute = Math.floor(seconds / 60);
      seconds = seconds % 60;
      let hour = Math.floor(minute / 60);
      minute = minute % 60;
      const day = Math.floor(hour / 24);
      hour = hour % 24;
      let remainTime
      if (day > 0) {
        remainTime = day + "d:" + hour + "h:" + minute + "m:" + seconds + "s";
      } else {
        remainTime = hour + "h:" + minute + "m:" + seconds + "s";
      }
      remainingMillis = remainingMillis - 1000;
      console.log(remainTime);
    }, 1000); 
  }
