需要在给定日期范围内写入 ngRx select 或 select 数据？

Question

我需要写一个 selector 到 select 实体数组列表数据。数据数组对象内容为 startDate 和 EndDate。但有些对象没有结束日期。如果 -> endDate 可用，我需要检查结束日期。如果结束日期为空，则该数据也应添加到地图中。需要一些专家的帮助来纠正这个 select 或逻辑。它将给出声纳问题也需要使用 '!==' 和 'Variables should not be shadowed' 就像一个 'select all' .

Start, End -> check Pass date between or Equal date range

The only start -> Check start date on or before the given date.

我的约会对象select逻辑：

   const selectReviewState =
  createSelector(selectAdminFeature,
    (appState) => appState.ReviewState);

const {
  selectAll,
} = ReviewAdaptor.getSelectors();

/**
 * Select all Review as an array
 */
const selectReviews = createSelector(
  selectReviewState,
  selectAll
);

/**
 *
 * Select Review data with in given range , during one year period past to future
 *
 */
export const selectAllReviewsDetailsModel = (planedDate: Date) => createSelector(
  selectReviews,
  (selectAll: ReviewModel[]) =>
    selectAll.filter(date => date.startDateTime.getTime() <= planedDate.getTime() &&
      (date.endDateTime != null && date.endDateTime.getTime() >= planedDate.getTime()))
);

Answer 1

moment 是非常强大的日期库，可以使日期计算变得容易。您可以像下面这样更新选择器

import moment from 'moment';

export const selectAllReviewsDetailsModel => createSelector(
  selectReviews,
  (selectAll: ReviewModel[], props) => {
    const { planedDate } = props;
    return selectAll.filter(date => 
        moment(date.startDateTime).isSameOrBefore(moment(planedDate)) &&
        moment(date.endDateTime).isValid() ? moment(date.startDateTime).isSameOrAfter(moment(planedDate)) : true)
  });

如果您注意到我将 planedDate 作为 props 传递，并且在组件方面您可以使用此选择器

const result = this.store.pipe(selectAllReviewsDetailsModel, { planedDate: '09/12/2002' })
