如何在RouterModule.forchild()；中使用scrollPositionRestoration？如何让页面在导航后始终在顶部滚动？

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

const routes: Routes = [
  // 定义你的路由
];

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

import { Component, OnInit, Renderer2 } from '@angular/core';

@Component({
  selector: 'app-your-component',
  templateUrl: './your-component.component.html',
  styleUrls: ['./your-component.component.css']
})
export class YourComponent implements OnInit {

  constructor(private renderer: Renderer2) { }

  ngOnInit() {
    // 在组件初始化时，将页面滚动到顶部
    this.renderer.setProperty(document.documentElement, 'scrollTop', 0);
  }

}

const routes: Routes = [
  {
    path: 'your-path',
    component: YourComponent
  }
];
