如何使用变量设置角度材质日期拾取器上的日期值？

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

@Component({
  selector: 'app-date-picker',
  templateUrl: './date-picker.component.html',
  styleUrls: ['./date-picker.component.css']
})
export class DatePickerComponent {
  selectedDate: Date = new Date(); // 初始化日期变量
}

<mat-form-field>
  <input matInput [matDatepicker]="picker" [(ngModel)]="selectedDate" placeholder="选择日期">
  <mat-datepicker-toggle matSuffix [for]="picker"></mat-datepicker-toggle>
  <mat-datepicker #picker></mat-datepicker>
</mat-form-field>

// 假设你想将日期设置为明天的日期
const tomorrow = new Date();
tomorrow.setDate(tomorrow.getDate() + 1);
this.selectedDate = tomorrow;

import { MAT_DATE_FORMATS, DateAdapter } from '@angular/material/core';
import { MomentDateAdapter } from '@angular/material-moment-adapter';

export const MY_FORMATS = {
  parse: {
    dateInput: 'LL',
  },
  display: {
    monthYearLabel: 'MMM YYYY',
    dateA11yLabel: 'LL',
    monthYearA11yLabel: 'MMMM YYYY',
  },
};

@Component({
  providers: [
    { provide: DateAdapter, useClass: MomentDateAdapter, deps: [MAT_DATE_LOCALE] },
    { provide: MAT_DATE_FORMATS, useValue: MY_FORMATS },
  ],
})
export class DatePickerComponent {
  // ...
}

import { FormsModule } from '@angular/forms';

@NgModule({
  imports: [
    // ...
    FormsModule,
    // ...
  ],
  // ...
})
export class AppModule { }
