- 创建需要的组件
ng g component home
ng g component news
ng g component newscontent
- 找到 app-routing.module.ts 配置路由
- 引入组件
import { HomeComponent } from './home/home.component';
import { NewsComponent } from './news/news.component';
import { NewscontentComponent } from'./newscontent/newscontent.component';
- 配置路由
const routes: Routes = [
{path: 'home', component: HomeComponent},
{path: 'news', component: NewsComponent},
{path: 'newscontent/:id', component: NewscontentComponent},
{ path: '', redirectTo: '/home', pathMatch: 'full' }
];
- 找到 app.component.html 根组件模板，配置 router-outlet 显示动态加载的路由
<h1><a routerLink="/home">首页</a> <a routerLink="/news">新闻</a> </h1>
<router-outlet></router-outlet>
Angular routerLink 跳转页面 默认路由
//匹配不到路由的时候加载的组件 或者跳转的路由
{ path: '**', /*任意的路由*/ //
component:HomeComponent,
redirectTo:'home'
}
设置选中样式
<h1>
<a [routerLink]="[ '/home' ]" routerLinkActive="active">首页</a>
<a [routerLink]="[ '/news' ]" routerLinkActive="active">新闻</a>
</h1>
.active{ color:red; }
动态路由
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' }
];
//跳转传值
<a [routerLink]="[ '/newscontent/',aid]">跳转到详情</a>
<a routerLink="/newscontent/{{aid}}">跳转到详情</a>
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);
}
动态路由的 js 跳转
import { Router } from '@angular/router';
export class HomeComponent implements OnInit {
constructor(private router: Router) { }
ngOnInit() { }
goNews(){
// this.router.navigate(['/news', hero.id]);
this.router.navigate(['/news']);
} }
路由 get 传值 js 跳转
- 引入 NavigationExtras
import { Router ,NavigationExtras} from '@angular/router';
2.定义一个 goNewsContent 方法执行跳转，用 NavigationExtras 配置传参。
goNewsContent(){
let navigationExtras: NavigationExtras = {
queryParams: { 'session_id': '123' },
fragment: 'anchor'
};
this.router.navigate(['/news'],navigationExtras); }
//获取 get 传值
constructor(private route: ActivatedRoute) { console.log(this.route.queryParams);
}
父子路由
{
path: 'news',
component:NewsComponent,
children: [
{ path:'newslist', component:NewslistComponent },
{ path:'newsadd', component:NewsaddComponent }
]
}
