UPDATE:
Now that Angular2 final was officially released, the correct way to do this is the following:
export class ChildComponent {
private sub: any;
private parentRouteId: number;
constructor(private route: ActivatedRoute) { }
ngOnInit() {
this.sub = this.route.parent.params.subscribe(params => {
this.parentRouteId = +params["id"];
});
}
ngOnDestroy() {
this.sub.unsubscribe();
}
}
ORIGINAL:
Here is how i did it using the “@angular/router”: “3.0.0-alpha.6” package:
export class ChildComponent {
private sub: any;
private parentRouteId: number;
constructor(
private router: Router,
private route: ActivatedRoute) {
}
ngOnInit() {
this.sub = this.router.routerState.parent(this.route).params.subscribe(params => {
this.parentRouteId = +params["id"];
});
}
ngOnDestroy() {
this.sub.unsubscribe();
}
}
In this example the route has the following format: /parent/:id/child/:childid
export const routes: RouterConfig = [
{
path: '/parent/:id',
component: ParentComponent,
children: [
{ path: '/child/:childid', component: ChildComponent }]
}
];
