如何使用momentjs检查当前时间是否在两次之间

Question

我想做什么：

  getOpenStatus = (restaurant: _Restaurant) => {
    const closeHour = moment(restaurant.close_at, "HH:mm A").hours();
    const closeMin = moment(restaurant.close_at, "HH:mm A").minutes();
    const openHour = moment(restaurant.open_at, "HH:mm A").hours();
    const openMin = moment(restaurant.open_at, "HH:mm A").minutes();
    const closeMoment = moment({ hours: closeHour, minutes: closeMin });
    const openMoment = moment({ hours: openHour, minutes: openMin });
    return moment().isAfter(openMoment) && moment().isBefore(closeMoment);
  }

假设当前时间是下午 4:00

上午 10:30 开门，晚上 11:30 关门

在这种情况下工作完美，因为时间在同一日期。

但是如果餐厅 23 小时营业呢：

上午 10:30 开门，上午 9:30 关门

那该如何处理呢？

Answer 1

getOpenStatus = (restaurant: _Restaurant) => {
    const closeHour = moment(restaurant.close_at, "HH:mm A").hours();
    const closeMin = moment(restaurant.close_at, "HH:mm A").minutes();
    const openHour = moment(restaurant.open_at, "HH:mm A").hours();
    const openMin = moment(restaurant.open_at, "HH:mm A").minutes();
    const closeMoment = moment({ hours: closeHour, minutes: closeMin });
    const openMoment = moment({ hours: openHour, minutes: openMin });

    if (closeMoment.isBefore(openMoment)) {
        if (moment().isAfter(closeMoment)) closeMoment.add(1, "days");
        else openMoment.subtract(1, "days");
    }

    return moment().isAfter(openMoment) && moment().isBefore(closeMoment);
}
