【React工作记录七十二】时间秒转换为毫秒

getTimeBySecond = (second) => {
    let days = parseInt(second / (1000 * 60 * 60 * 24));
    let hours = parseInt((second % (1000 * 60 * 60 * 24)) / (1000 * 60 * 60));
    let minutes = parseInt((second % (1000 * 60 * 60)) / (1000 * 60));
    let seconds = (second % (1000 * 60)) / 1000;
    seconds = Math.floor(seconds) + '秒';
    let result =
      (days > 0 ? `${days}天` : '') +
      (hours > 0 ? `${hours}时` : '') +
      (minutes > 0 ? `${minutes}分` : '') +
      seconds;
