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;
      }
    });
  }
}

如果您使用服务器端呈现，则应该注意不要在服务器上使用窗口运行代码，因为服务器上不存在该变量。这将导致代码被破坏。

export class AppComponent implements OnInit {
  routerSubscription: Subscription;

  constructor(private router: Router,
              @Inject(PLATFORM_ID) private platformId: any) {}

  ngOnInit() {
    if (isPlatformBrowser(this.platformId)) {
      this.routerSubscription = this.router.events
        .filter(event => event instanceof NavigationEnd)
        .subscribe(event => {
          window.scrollTo(0, 0);
        });
    }
  }

  ngOnDestroy() {
    this.routerSubscription.unsubscribe();
  }
}

isPlatformBrowser是一个函数，用于检查当前应用程序所呈现的平台是否是浏览器。我们给它注入platformId。

它也可以检查变量窗口的存在，为了安全起见，像这样:

if (typeof window != 'undefined')

@Fernando埃切维里亚 太棒了!但是这段代码不能在哈希路由器或惰性路由器中工作。因为它们不会触发位置更改。 可以试试这个:

private lastRouteUrl: string[] = [] ngOnInit(): void { This.router.events.subscribe ((ev) => { const len = this.lastRouteUrl.length if (ev instanceof NavigationEnd) { this.lastRouteUrl.push (ev.url) If (len > 1 && ev。Url === this。lastRouteUrl[len - 2]) { 返回 ｝ 窗口。scrollTo (0, 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

下面在执行时调用它，它为我工作%100

  document.body.scrollTop = 0;

如

 this.brandCollectionList$.subscribe((response) => {
  document.body.scrollTop = 0;

});

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;
