constructor(private _router: Router, private _routeParams: RouteParams) { } onSelect() { this._router.navigate(['ChildRoute1Detail']); } }; 路由参数 通过在routelink或route.navigate中可以指定参数,如下 <a [routerLink]="['ChildRoute1Detail', {param1: param1}]">子路由明细1</a> this._...
// 路由配置{path:'detail/:id',component:DetailComponent}// 传参方式<a[routerLink]="['/detail', detail.id]"></a>this.router.navigate(['/detail',this.detail.id]);// 读取参数this.route.snapshot.paramMap.get('id');// 页面路径`http://localhost:4200/detail/1 路由可选参数 // 路由配...
AngularJS路由主要有内置的ngRoute和一个基于ngRoute开发的第三方路由模块ui-router,内置的ngRoute有时满足开发需求,使用ui-router可以解决很多原生ngRoute的不足。 AngularJS的路由实际上是一种纯前端的解决方案,它的本质是:当请求一个url时,根据路由配置这个url,然后再请求模板片段,并插入到ng-view中。AngularJS的...
要从Angular 5中的paramMap获取查询参数,可以按照以下步骤进行操作: 首先,在组件中导入ActivatedRoute模块:import { ActivatedRoute } from '@angular/router'; 在组件的构造函数中注入ActivatedRoute:constructor(private route: ActivatedRoute) { } 在需要获取查询参数的地方,使用subscribe方法来订阅paramMap的变化,并在...
import { HttpClient } from '@angular/common/http'; export class UserComponent implements OnInit { user: any; constructor(private route: ActivatedRoute, private http: HttpClient) {} ngOnInit() { this.route.params.subscribe(params => { const userId = params['id']; this.http.get(`https:/...
route.snapshot.paramMap.get('id'); this.hero$ = this.service.getHero(id); } 6.3 两者的区别ActivatedRoute:接收的是Observable对象,表示在该组件的生存期间,只要路由发生变化了,组件也会发生对应的变化;例如上文中的例子,当路由中的id发生变化时,页面会立马渲染对应id的hero; Snapshot:例如上文中的例子,...
`Route`/`Routes` type so that TypeScript does not infer the type as `string`. - When returning a `Promise` from the `LoadChildrenCallback`, the possible type is now restricted to `Type<any>|NgModuleFactory<any>` rather than `any`. ...
You can use this in $routeProvider.resolve. As Restangular returns promises, you can return any of the methods in the $routeProvider.resolve and you'll get the real object injected into your controller if you want. It doesn't have all those $resource bugs. Restangular doesn't have problem...
