javascript - Angular2 子元件控制父元件的路由

我有一個主要的父組件，它包含一個內建的頂部導航、一個獨立的側邊欄導航組件，以及一個主要內容的 div，用來放置主要組件的 <router-outlet>。我正在試圖理解如何讓子導航組件中的連結改變父主要組件中的 router-outlet。

```

Main Component
@Component({
  selector: 'app',
  templateUrl: 'mainComponent.html',
  encapsulation: ViewEncapsulation.None,
  directives: [ROUTER_DIRECTIVES,ChildSidenav],
})
@RouteConfig([
  { path: '/', component: HomeCmp, as: 'Home' }, //for top nav
  { path: '/about', component: AboutCmp, as: 'About' }, //for top nav
  { path: '/user', component: UserCmp, as: 'User'}, //for top nav
  { path: '/data/...', component: SidenavBasicUsage, as: 'Data'}, //link in child component
  { path: '/dates', component: SelectDatesComponent, as: 'Dates'}, //link in child component
  { path: '/edit/paths', component: EditPathsComponent, as: 'EditPaths'}, //link in child component
  { path: '/edit/filters', component: EditFiltersComponent, as: 'EditFilters'}, //link in child component
])
export class AppCmp {}

Child Component
@Component({
  selector: 'left-control',
  templateUrl: 'sidebar.component.html',
  moduleId: module.id,
  directives: [ROUTER_DIRECTIVES],
})
@RouteConfig([
  {path: '/',name: 'Data',component: SelectDataComponent,useAsDefault: true},
  {path: '/dates',name: 'Dates',component: SelectDatesComponent},
  {path: '/edit/paths',name: 'EditPaths',component: EditPathsComponent},
  {path: '/edit/filters',name: 'EditFilters',component: EditFiltersComponent}
])
export class SideNavComponent{}

```

答案＃1

我還沒有嘗試過所有這些方法，但我覺得它們應該可行：

import {Router} from 'angular2/router'

...

constructor(private router:Router) {}

someMethod() {
  this.router.parent.navigate(['About']);
  this.router.navigate(['/About']);
  this.router.navigate(['../About']);
}

使用 [routerLink]="..." 時效果相同（除了第一個範例）
