Angular -创建一个函数，该函数采用2个日期和一周中的某一天，并创建一组包含同一天的日期的数组

import { Component } from '@angular/core';

@Component({
  selector: 'app-root',
  template: '{{ datesArray }}'
})
export class AppComponent {
  datesArray: Date[];

  constructor() {
    this.datesArray = this.generateDates(new Date('2022-01-01'), new Date('2022-12-31'), 'Sunday');
  }

  generateDates(startDate: Date, endDate: Date, dayOfWeek: string): Date[] {
    const datesArray: Date[] = [];
    const currentDay = startDate.getDay();

    // 寻找第一个与目标星期几匹配的日期
    const firstDate = new Date(startDate);
    firstDate.setDate(startDate.getDate() + (7 - currentDay + this.getDayIndex(dayOfWeek)) % 7);

    // 生成日期数组
    let currentDate = firstDate;
    while (currentDate <= endDate) {
      datesArray.push(new Date(currentDate));
      currentDate.setDate(currentDate.getDate() + 7);
    }

    return datesArray;
  }

  getDayIndex(dayOfWeek: string): number {
    const days = ['Sunday', 'Monday', 'Tuesday', 'Wednesday', 'Thursday', 'Friday', 'Saturday'];
    return days.indexOf(dayOfWeek);
  }
}
