I have a <a>
tag like below,
<a [routerLink]="[/Person']">Person</a>
So I want to pass the person.id
to this /Person
router. How can I pass it & handle it on @RouteConfig
like params
in Angular 1
Pass to router link:
<a [routerLink]="['/Person', person.id]">Person</a>
Handle in component:
this.route.params.subscribe(
(params: Params) => {
this.id = params['id'];
}
);
Second way:
this.route.params.forEach(
(params: Params) => {
this.id = params['id'];
}
);
In this example you have to inject ActivatedRoute
(e.g as route property) like that:
constructor(private route: ActivatedRoute) {}
If you subscribe - it is important to unsubscribe Observable
to prevent memory leaks.
Full example:
export class SimpleComponent implements OnInit, OnDestroy {
private id: number;
private route$: Subscription;
constructor(private route: ActivatedRoute) {}
ngOnInit() {
this.route$ = this.route.params.subscribe(
(params: Params) => {
this.id = +params['id']; // cast to number
}
);
}
ngOnDestroy() {
if (this.route$) this.route$.unsubscribe();
}
}
Config:
export const routes = [
...
{ path : 'Person/:id', component : ...},
...
];
Also, @RouteConfig
is deprecated.
