如何在angular材质日期选择器中隐藏周末日期

import { Pipe, PipeTransform } from '@angular/core';

@Pipe({
  name: 'weekendFilter'
})
export class WeekendFilterPipe implements PipeTransform {
  transform(dates: Date[]): Date[] {
    return dates.filter(date => !this.isWeekend(date));
  }

  private isWeekend(date: Date): boolean {
    const day = date.getDay();
    return day === 0 || day === 6; // 周六和周日为周末
  }
}

<mat-form-field>
  <input matInput [matDatepicker]="picker" [value]="selectedDate | weekendFilter">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>
