如何过滤与另一个对象列表中的某些条件不匹配的对象列表

Question

我有一些业务的可选工作时间对象数组（5 分钟跳跃）。

此外，我还有一个约会对象数组。

我想过滤可选的工作时间，如果这些时间之间有现有的约会。

我用 moment.js 库尝试了这个解决方案：

  const optionalWorkingHours = [
    { from: "05:00", to: "05:05" },
    { from: "05:05", to: "05:10" },
    { from: "05:10", to: "05:15" },
    { from: "05:15", to: "05:20" },
    // ....
  ];

  const appointments = [
    { from: "05:00", to: "05:05" },
    { from: "05:30", to: "06:00" },
    { from: "07:50", to: "08:00" }
  ];

  const availableHours = optionalWorkingHours.filter((o) => {
    const optionalFrom = moment(o.from, "HH:mm");
    const optionalTo = moment(o.to, "HH:mm");

    return appointments.some((c) => {
      const currentFrom = moment(c.from, "HH:mm");
      const currentTo = moment(c.to, "HH:mm");

      const isBusyHours =
        currentFrom.isSameOrAfter(optionalFrom, "hour") &&
        currentTo.isSameOrBefore(optionalTo, "hour");

      return !isBusyHours;
    });
  });

当前结果：重复可用工作时间

预期结果：不与约会数组重叠的可用工作时间数组。

这并不容易，但我认为您的登记 .some() 并不完整。你能试试这个解决方案吗：

const optionalWorkingHours = [
  { from: "05:00", to: "05:05" }, // no
  { from: "05:05", to: "05:10" },
  { from: "05:10", to: "05:15" },
  { from: "05:15", to: "05:20" },
  { from: "05:20", to: "05:25" },
  { from: "05:25", to: "05:30" },
  { from: "05:30", to: "05:35" }, // no
  { from: "05:35", to: "05:40" }, // no
  { from: "05:40", to: "05:45" }, // no
  { from: "05:45", to: "05:50" }, // no
  { from: "05:50", to: "05:55" }, // no
  { from: "05:55", to: "06:00" }, // no
  { from: "06:00", to: "06:05" }, //
  // ....
];

const appointments = [
  { from: "05:00", to: "05:05" },
  { from: "05:30", to: "06:00" },
  { from: "07:50", to: "08:00" }
];

const availableHours = optionalWorkingHours.filter((o) => {
  const optionalFrom = moment(o.from, "HH:mm");
  const optionalTo = moment(o.to, "HH:mm");

  const check = appointments.some((appointment) => {
    const appointmentFrom = moment(appointment.from, "HH:mm");
    const appointmentTo = moment(appointment.to, "HH:mm");

    const isBusyHours =
      (optionalFrom.isSame(appointmentFrom) && optionalTo.isSame(appointmentTo)) ||
      (optionalFrom.isSame(appointmentFrom) && optionalTo.isBetween(appointmentFrom, appointmentTo)) ||
      (optionalFrom.isBetween(appointmentFrom, appointmentTo) && optionalTo.isSame(appointmentTo)) ||
      (optionalFrom.isBetween(appointmentFrom, appointmentTo) && optionalTo.isBetween(appointmentFrom, appointmentTo))


    return isBusyHours;
  });

  return !check;
});

console.table(availableHours);
console.log(availableHours);
