angular中的动态路由

1.配置动态路由

 

const routes: Routes = [
  {path: 'home', component: HomeComponent},
  {path: 'news', component: NewsComponent},
  {path: 'newscontent/:id', component: NewscontentComponent},
  {
    path: '',
    redirectTo: '/home',
    pathMatch: 'full'
} ];

 

2.跳转传值

<a [routerLink]="[ '/newscontent/',aid]">跳转到详情</a> 
<a routerLink="/newscontent/{{aid}}">跳转到详情</a>

3.获取动态路由的值

import { ActivatedRoute} from '@angular/router';

   constructor( private route: ActivatedRoute) { }

ngOnInit() {
  console.log(this.route.params);
  this.route.params.subscribe(data=>this.id=data.id);
}

goNewsContent(){
     let navigationExtras: NavigationExtras = {
       queryParams: { 'session_id': '123' },
       fragment: 'anchor'
};
     this.router.navigate(['/news'],navigationExtras);
  }

   constructor(private route: ActivatedRoute) {
     console.log(this.route.queryParams);
}
