routerLink inside <mat-tab> angular material

问题

<a routerLink = "/add"></a><mat-tab  label="Add Identity"></mat-tab>
or
<mat-tab  label="Add Identity"> <a routerLink = "/add"></a></mat-tab>.

I am new to Angular, Trying to use routing with above Angular material component. But its not appending the url when i am clicking on Home tab. Any help on this.

回答1:

you can actually combine them into one like this:

<a mat-tab-link [routerLink]="/add">Add Identity</a>

you'll also need to make sure you're using <nav mat-tab-nav-bar>, instead of <mat-tab-group>.

documentation here: https://material.angular.io/components/tabs/overview#tabs-and-navigation

This is how i have implemented.

app.component.html

<nav mat-tab-nav-bar>
  <a mat-tab-link
  *ngFor="let link of navLinks"
  [routerLink]="link.link"
  routerLinkActive #rla="routerLinkActive"
  [active]="rla.isActive">
 {{link.label}}
</a>
</nav>
<router-outlet></router-outlet>

AppComponent

export class AppComponent implements OnInit{
  title = 'app';
  navLinks: any[];
  activeLinkIndex = -1;

  constructor(private router: Router) {
    this.navLinks = [
        {
            label: 'TabTest1',
            link: './tabtest1',
            index: 0
        }, {
            label: 'Tab Test2',
            link: './tabtest2',
            index: 1
        }, {
            label: 'Tab Test3',
            link: './tabtest3',
            index: 2
        }, 
    ];
}
ngOnInit(): void {
  this.router.events.subscribe((res) => {
      this.activeLinkIndex = this.navLinks.indexOf(this.navLinks.find(tab => tab.link === '.' + this.router.url));
  });
}
}

routing.module.ts

const routes: Routes = [
  { path: '', redirectTo: '/tabtest1', pathMatch: 'full' },
  { path: 'tabtest1', component:  TestComponent1},
  { path: 'tabtest2', component:  TestComponent2},

];

export const appRouting = RouterModule.forRoot(routes);



@NgModule({
  imports: [
    RouterModule.forRoot(routes),
    CommonModule
  ],
  exports:[
    RouterModule
  ],

  declarations: []
})
export class AppRoutingModule { }

I hope this helps someone

if you need set routerLink on Click <mat-tab> inside <mat-tab-group> without any workarounds and changes of current code with mat-tab-nav logic things directly - you can use mat-tab-group listener (selectedTabChange)="onTabChanged($event)":

.html:

<mat-tab-group
  (selectedTabChange)="onTabChanged($event)"
>
<mat-tab label="Link to some thing"></mat-tab> <!-- empty stub tab only for link -->
<mat-tab label="Some content tab"> ... content there ... </mat-tab>

</mat-tab-group>

.ts:

onTabChanged(event: MatTabChangeEvent): void {
    switch (event.index) {
      case 0: // index of the tab
        // this is our stub tab for link
        this.router.navigate(['/admin/my-link']);
        break;
      case 1:
        // do stuff with content or do nothing :)
        break;
    }
