How do I get the RouteParams from a parent component?
App.ts
:
@Component({
...
})
@RouteConfig([
{path: '/', component: HomeComponent, as: 'Home'},
{path: '/:username/...', component: ParentComponent, as: 'Parent'}
])
export class HomeComponent {
...
}
And then, in the ParentComponent
, I can easily get my username param and set the child routes.
Parent.ts
:
@Component({
...
})
@RouteConfig([
{ path: '/child-1', component: ChildOneComponent, as: 'ChildOne' },
{ path: '/child-2', component: ChildTwoComponent, as: 'ChildTwo' }
])
export class ParentComponent {
public username: string;
constructor(
public params: RouteParams
) {
this.username = params.get('username');
}
...
}
But then, how can I get this same 'username' parameter in those child components? Doing the same trick as above, doesn't do it. Because those params are defined at the ProfileComponent or something??
@Component({
...
})
export class ChildOneComponent {
public username: string;
constructor(
public params: RouteParams
) {
this.username = params.get('username');
// returns null
}
...
}

UPDATE:
Now that Angular2 final was officially released, the correct way to do this is the following:

In this example the route has the following format: /parent/:id/child/:childid
