JavaScript 时间戳取 年月日时分秒

  // 时间戳转换
  function toHHms(timestamp) {
    var time = new Date(timestamp);
    var year = time.getFullYear();
    var month = time.getMonth() + 1;
    var date = time.getDate();
    var hours = time.getHours();
    var minutes = time.getMinutes();
    var seconds = time.getSeconds();
    return (
      year +
      "-" +
      this.toHHmsZero(month) +
      "-" +
      this.toHHmsZero(date) +
      " " +
      this.toHHmsZero(hours) +
      ":" +
      this.toHHmsZero(minutes) +
      ":" +
      this.toHHmsZero(seconds)
    );
  },

  // 时间戳是否加0
  function toHHmsZero(m) {
    return m < 10 ? "0" + m : m;
  }
