      <a href="#account-services">Services</a>
    </li>
    <li>
      <a [routerLink]="['//account/'+account.account_id]" fragment="account-about">About</a>

</div>

ts component:

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

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

  private fragment: string;

  constructor(private route: ActivatedRoute) {}

  ngOnInit() {
    this.route.fragment.subscribe(fragment => { this.fragment = fragment; });
  }

  ngAfterViewInit(): void {
    try {
      document.querySelector('#' + this.fragment).scrollIntoView();
    } catch (e) {
      console.log(e);
    }
  }
}

回答1:

install this package
ng2-page-scroll

after import in your app.module.ts

    import {Ng2PageScrollModule} from 'ng2-page-scroll';

    @NgModule({
        imports: [
            /* Other imports here */
            Ng2PageScrollModule
            ]
    })

   export class AppModule {
   }

and test in your component html

<a pageScroll href="#home">Testing</a>
<div id="home">

回答2:

Use fragment as you did and bind to a click event like so:

in the html

<a fragment="account-about" (click)="navigateToSection('account-about')>About</a>

<div id="account-about">...</div>

in the ts

public navigateToSection(section: string) {
      window.location.hash = '';
      window.location.hash = section;
}

回答3:

try this

this.route.fragment.subscribe(fragment => { 
                      setTimeout(() => {
                            this.scrollTo(fragment);
                        }, 300);
     });
