出于我们的目的,只需要理解开发者和路由器(router)都用 ActivatedRoute 获取导航的相关信息,例如查询参数(query parameters)和组件内容。 示例应用 我们将使用一个非常简单的应用作为运行示例。这是路由器配置。 const ROUTES = [ { path: 'users', component: UsersComponent, canActivate: [CanActivateGuard], resolve...
On the receiving side, and especially in the case of detail child routes where we want to navigate from one detail into the other, we are going to see how to use the queryParams observable to receive the navigation query parameters. First way, using in html: {{hero.name}} 1. 2. 3. ...
The default is "emptyOnly," which inherits those only for path-less or component-less routes. We're going to set it to "always" to enable unconditional inheritance of parent parameters, data, and resolved data in child routes. imports: [ BrowserModule, RouterModule.forRoot(routes,{ paramsInher...
如果想要测试真实导航,可以使用RouterTestingModule,添加所有的路由providers和directives import{RouterTestingModule}from'@angular/router/testing';TestBed.configureTestingModule({imports:[RouterTestingModule.withRoutes([{path:'',component:BlankCmp},{path:'simple',component:SimpleCmp}])]})...
Route 定义单个路由的配置对象,一组routes 数组中,单条route 对象的配置,将给定URL与每一个路由进行匹配 interface Route { // 配合的路径,`**` 通配符能与任何URL匹配,`/*` 根路径,也称之为绝对路径 path?: string // 路径匹配策略,
If I comment out all my routes the query parameters will stick however, the moment I include a route the query parameters are removed on page load. Below is a stripped down copy of my routes file with one route import{NavigationComponent}from"./navigation/components/navigation.component";import...
component = HomeComponent; // result: home = {} // so error const routes: Routes = [home]; - right const home: Route = { path: '', component: HomeComponent } Finally, for your problem solution, you can do something like this: // Define them first // MainCompon...
Wildcard Routes Example In the basic Angular Routing, you just can navigate to the routing that defines in the app-routing.module.ts and URL query parameters. Unfortunately, when you point to a different URL other than that, the view will be redirected to the root URL. If you want to ha...
forRoot() takes a service configuration object and returns a ModuleWithProviders, which is a simple object with the following properties: ngModule: in this example, the GreetingModule class providers: the configured providers 例子: const appRoutes: Routes = [ ...
forRoot(routes: Routes, config?: ExtraOptions) : ModuleWithProviders 为什么叫forRoot呢?因为这个路由定义是应用在应用根部的,你可能猜到了还有一个工厂方法叫forChild,后面我们会详细讲。接下来我们看一下forRoot接收的参数,参数看起来是一个数组,每个数组元素是一个{path: 'xxx', component: XXXComponent}这个样...
