Angular-da marshrut parametrlaridan komponentda foydalanish

Keling, endi marshrut parametrlarini komponent klassida qanday ishlatishimizni ko'rib chiqaylik.

Faraz qilaylik, bizda parametrlar bilan quyidagi marshrut mavjud:

app/app.routes.tsconst routes: Routes = [
  { path: 'aaaa/:id', component: AaaaComponent },
  { path: 'bbbb', component: BbbbComponent },
];

Faraz qilaylik, bizda turli parametrlar bilan ushbu komponentga o'tish uchun quyidagi havolalar mavjud:

app/app.component.html<nav>
  <a
    routerLink="/aaaa/1"
    routerLinkActive="active"
  >
    1
  </a>
  <a
    routerLink="/aaaa/2"
    routerLinkActive="active"
  >
    2
  </a>
  <a
    routerLink="/aaaa/3"
    routerLinkActive="active"
  >
    3
  </a>
</nav>

Faraz qilaylik, bizda quyidagi massiv bola komponentda mavjud:

app/aaaa/aaaa.component.tslet arr: string = [
  'a', 'b', 'c', 'd', 'e'
];

export class AaaaComponent {

}

Keling, marshrut parametrining qiymatiga qarab, massivning mos elementini olamiz:

app/aaaa/aaaa.component.tsexport class AaaaComponent {
  constructor(private activateRoute: ActivatedRoute) {
    let params = activateRoute.snapshot.params;
    let id = params['id'];
    
    this.value = arr[id];
  }
}

Olingan elementni ko'rinishda chiqaramiz:

app/aaaa/aaaa.component.htmlqiymat: {{ value }}

    name: 'user1',
    surn: 'surn1',
  },
  {
    name: 'user2',
    surn: 'surn2',
  },
  {
    name: 'user3',
    surn: 'surn3',
  },
]
