vue的filters时间过滤器

  filters: {
    formatTime: function(value) {
      let time = new Date(value * 1000);
      let year = time.getFullYear();
      let month = time.getMonth() + 1;
      if (month < 10) {
        month = "0" + month;
      }
      let day = time.getDate() < 10 ? "0" + time.getDate() : time.getDate();
      let hour = time.getHours() < 10 ? "0" + time.getHours() : time.getHours();
      let minute =
        time.getMinutes() < 10 ? "0" + time.getMinutes() : time.getMinutes();
      let second =
        time.getSeconds() < 10 ? "0" + time.getSeconds() : time.getSeconds();
      return `${year}-${month}-${day} ${hour}:${minute}:${second}`;
    }
  },
