如果你只是需要滚动页面到顶部，你可以这样做(不是最好的解决方案，但很快)

document.getElementById('elementId').scrollTop = 0;

Angular最近引入了一个新特性，在Angular的路由模块内部做了如下更改

@NgModule({
  imports: [RouterModule.forRoot(routes,{
    scrollPositionRestoration: 'top'
  })],

大家好，这在angular 4中是适用的。你只需要引用父节点来滚动路由器更改

layout.component.pug

.wrapper(#outlet="")
    router-outlet((activate)='routerActivate($event,outlet)')

layout.component.ts

 public routerActivate(event,outlet){
    outlet.scrollTop = 0;
 }`

lastRoutePath?: string;

ngOnInit(): void {
  void this.router.events.forEach((event) => {
    if (event instanceof ActivationEnd) {
      if (this.lastRoutePath !== event.snapshot.routeConfig?.path) {
        window.scrollTo(0, 0);
      }
      this.lastRoutePath = event.snapshot.routeConfig?.path;
    }
  });
}

如果你停留在同一个页面上，它不会滚动到顶部，而只是改变了slug / id或其他东西

Here's a solution that I've come up with. I paired up the LocationStrategy with the Router events. Using the LocationStrategy to set a boolean to know when a user's currently traversing through the browser history. This way, I don't have to store a bunch of URL and y-scroll data (which doesn't work well anyway, since each data is replaced based on URL). This also solves the edge case when a user decides to hold the back or forward button on a browser and goes back or forward multiple pages rather than just one.

附注:我只测试了最新版本的IE、Chrome、FireFox、Safari和Opera(截至本文)。

希望这能有所帮助。

export class AppComponent implements OnInit {
  isPopState = false;

  constructor(private router: Router, private locStrat: LocationStrategy) { }

  ngOnInit(): void {
    this.locStrat.onPopState(() => {
      this.isPopState = true;
    });

    this.router.events.subscribe(event => {
      // Scroll to top if accessing a page, not via browser history stack
      if (event instanceof NavigationEnd && !this.isPopState) {
        window.scrollTo(0, 0);
        this.isPopState = false;
      }

      // Ensures that isPopState is reset
      if (event instanceof NavigationEnd) {
        this.isPopState = false;
      }
    });
  }
}

这对我来说最适合所有导航更改，包括哈希导航

constructor(private route: ActivatedRoute) {}

ngOnInit() {
  this._sub = this.route.fragment.subscribe((hash: string) => {
    if (hash) {
      const cmp = document.getElementById(hash);
      if (cmp) {
        cmp.scrollIntoView();
      }
    } else {
      window.scrollTo(0, 0);
    }
  });
}
