使用说明

Every node in the route tree is an ActivatedRoute instance that knows about the "consumed" URL segments, the extracted parameters, and the resolved data. Use the ActivatedRoute properties to traverse the tree from any node.

Example

@Component({templateUrl:'template.html'}) class MyComponent { constructor(router: Router) { const state: RouterState = router.routerState; const root: ActivatedRoute = state.root; const child = root.firstChild; const id: Observable<string> = child.params.map(p => p.id); //... } }
      
      @Component({templateUrl:'template.html'})
class MyComponent {
  constructor(router: Router) {
    const state: RouterState = router.routerState;
    const root: ActivatedRoute = state.root;
    const child = root.firstChild;
    const id: Observable<string> = child.params.map(p => p.id);
    //...
  }
}
