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;

});

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;
 }`

这段代码背后的主要思想是将所有访问过的url和各自的scrollY数据保存在一个数组中。每当用户放弃一个页面(NavigationStart)，这个数组就会被更新。每当用户进入一个新页面(NavigationEnd)时，我们决定是否恢复Y位置，这取决于我们如何到达这个页面。如果使用了某个页面上的引用，则滚动到0。如果使用浏览器后退/前进特性，则滚动到保存在数组中的Y。对不起，我的英语不好:)

import { Component, OnInit, OnDestroy } from '@angular/core';
import { Location, PopStateEvent } from '@angular/common';
import { Router, Route, RouterLink, NavigationStart, NavigationEnd, 
    RouterEvent } from '@angular/router';
import { Subscription } from 'rxjs/Subscription';

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

  private _subscription: Subscription;
  private _scrollHistory: { url: string, y: number }[] = [];
  private _useHistory = false;

  constructor(
    private _router: Router,
    private _location: Location) {
  }

  public ngOnInit() {

    this._subscription = this._router.events.subscribe((event: any) => 
    {
      if (event instanceof NavigationStart) {
        const currentUrl = (this._location.path() !== '') 
           this._location.path() : '/';
        const item = this._scrollHistory.find(x => x.url === currentUrl);
        if (item) {
          item.y = window.scrollY;
        } else {
          this._scrollHistory.push({ url: currentUrl, y: window.scrollY });
        }
        return;
      }
      if (event instanceof NavigationEnd) {
        if (this._useHistory) {
          this._useHistory = false;
          window.scrollTo(0, this._scrollHistory.find(x => x.url === 
          event.url).y);
        } else {
          window.scrollTo(0, 0);
        }
      }
    });

    this._subscription.add(this._location.subscribe((event: PopStateEvent) 
      => { this._useHistory = true;
    }));
  }

  public ngOnDestroy(): void {
    this._subscription.unsubscribe();
  }
}

只需点击动作就可以轻松完成

在你的主组件html引用#scrollContainer

<div class="main-container" #scrollContainer>
    <router-outlet (activate)="onActivate($event, scrollContainer)"></router-outlet>
</div>

在主组件.ts中

onActivate(e, scrollContainer) {
    scrollContainer.scrollTop = 0;
}

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]
})

这个解决方案基于@FernandoEcheverria和@GuilhermeMeireles的解决方案，但它更简洁，并且可以使用Angular路由器提供的popstate机制。这允许存储和恢复多个连续导航的滚动级别。

我们将每个导航状态的滚动位置存储在一个地图scrollLevels中。一旦有了popstate事件，即将被恢复的状态ID就会由Angular路由器提供:event. restoredstate . navigationid。然后，这将用于从scrollLevels获取该状态的最后一个滚动级别。

如果路由没有存储滚动级别，它将滚动到顶部，正如您所期望的那样。

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

@Component({
    selector: 'my-app',
    template: '<ng-content></ng-content>',
})
export class AppComponent implements OnInit {

  constructor(private router: Router) { }

  ngOnInit() {
    const scrollLevels: { [navigationId: number]: number } = {};
    let lastId = 0;
    let restoredId: number;

    this.router.events.subscribe((event: Event) => {

      if (event instanceof NavigationStart) {
        scrollLevels[lastId] = window.scrollY;
        lastId = event.id;
        restoredId = event.restoredState ? event.restoredState.navigationId : undefined;
      }

      if (event instanceof NavigationEnd) {
        if (restoredId) {
          // Optional: Wrap a timeout around the next line to wait for
          // the component to finish loading
          window.scrollTo(0, scrollLevels[restoredId] || 0);
        } else {
          window.scrollTo(0, 0);
        }
      }

    });
  }

}
