js-时间戳格式化成“yyyy-MM-dd hh:mm:ss”格式

    timeFormat(timestamp) {
      if (timestamp) {
        var time = new Date(timestamp);
        var year = time.getFullYear();
        var month =
          time.getMonth() + 1 < 10
            ? "0" + (time.getMonth() + 1)
            : time.getMonth() + 1;
        var day = time.getDate() < 10 ? "0" + time.getDate() : time.getDate();
        var hour =
          time.getHours() < 10 ? "0" + time.getHours() : time.getHours();
        var minute =
          time.getMinutes() < 10 ? "0" + time.getMinutes() : time.getMinutes();
        var second =
          time.getSeconds() < 10 ? "0" + time.getSeconds() : time.getSeconds();
        return (
          year +
          "-" +
          month +
          "-" +
          day +
          " " +
          hour +
          ":" +
          minute +
          ":" +
          second
        );
      } else {
