html:
<router-outlet></router-outlet>
成分:
@Component({
selector: 'xx',
templateUrl: './xx.html',
styleUrls: ['./xx.css'],
providers: [ RouterOutlet]
})
export class AppComponent {
constructor(private routeroutlet: RouterOutlet){ }
getref() {
console.log(this.routeroutlet);
console.log('refresh', this.routeroutlet.component);
}
}
このエラーが発生します

上記のコンソールの結果はrouteroutlet objのコンソールです。
ルーターアウトレットでレンダリングされるコンポーネントのインスタンスにアクセスしたい。コンポーネントのインスタンスにアクセスするにはどうすればよいですか?
RouterOutletをプロバイダーとして使用しないでください。代わりに(activate)属性を次のようにルーターアウトレットタグに追加します。
<router-outlet (activate)="onRouterOutletActivate($event)"></router-outlet>
そして、ルーターアウトレット要素を含むコンポーネント(AppComponentクラス)で、onRouterActivateメソッドを実装する必要があります。
public onRouterOutletActivate(event : any) {
console.log(event);
}
これにより、イベントパラメータでルートコンポーネントインスタンスが提供されます。この例では、Webコンソールに書き込まれます。
