你也可以在Route.ts中使用scrollOffset。 参考Router ExtraOptions

@NgModule({
  imports: [
    SomeModule.forRoot(
      SomeRouting,
      {
        scrollPositionRestoration: 'enabled',
        scrollOffset:[0,0]
      })],
  exports: [RouterModule]
})

@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) ｝ }) ｝

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')

除了@Guilherme Meireles提供的完美答案， 您可以通过添加平滑滚动来调整实现，如下所示

 import { Component, OnInit } from '@angular/core';
    import { Router, NavigationEnd } from '@angular/router';

    @Component({
        selector: 'my-app',
        template: '<ng-content></ng-content>',
    })
    export class MyAppComponent implements OnInit {
        constructor(private router: Router) { }

        ngOnInit() {
            this.router.events.subscribe((evt) => {
                if (!(evt instanceof NavigationEnd)) {
                    return;
                }
                window.scrollTo(0, 0)
            });
        }
    }

然后添加下面的代码片段

 html {
      scroll-behavior: smooth;
    }

到你的样式。css

如果你用相同的路径加载不同的组件，那么你可以使用ViewportScroller来实现同样的事情。

import { ViewportScroller } from '@angular/common';

constructor(private viewportScroller: ViewportScroller) {}

this.viewportScroller.scrollToPosition([0, 0]);

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;
      }
    });
  }
}
