当用angular 11导航回到上一页时，如何保持滚动到的位置？

import { NgModule } from '@angular/core';
import { RouterModule, Routes, Scroll } from '@angular/router';

const routes: Routes = [
  // 路由配置...
];

@NgModule({
  imports: [RouterModule.forRoot(routes, { scrollPositionRestoration: 'enabled' })],
  exports: [RouterModule]
})
export class AppRoutingModule { }

import { Location } from '@angular/common';
import { Scroll } from '@angular/router';

@Component({
  // 组件配置...
})
export class YourComponent {

  constructor(private location: Location, private scroll: Scroll) { }

  goBack() {
    this.location.back();
    this.scroll.scrollToPosition([window.scrollX, window.scrollY]);
  }
}
