从子组件路由到父路由器出口-Java 学习之路

我已经设置了一个plnkr来展示我想要问的问题

我在网络应用程序中有一些组件，

父组件， App

@Component({
  selector: 'my-app',
  providers: [],
  template: `
    <div class="main-container">
      <h2>This is the base. This div must be seen on app pages</h2>
      <a [routerLink]="['Home']"> Home </a> | 
      <a [routerLink]="['Users']"> Users  </a> | 
      <a [routerLink]="['Contact']"> Contact </a>
    </div>

    <router-outlet></router-outlet>
  `,
  directives: [ROUTER_DIRECTIVES]
})

@RouteConfig([
  {
    path: '/',
    name: 'Home',
    component: HomeComponent,
    useAsDefault: true

  },
  {
    path: '/users/...',
    name: 'Users',
    component: UsersComponent
  },
  {
    path: '/contact',
    name: 'Contact',
    component: ContactComponent
  }
])
export class App {

}

UsersComponent 被加载到路径 /users 的父控制器的 router-outlet ，如下所示，

@Component({
  selector: 'my-app',
  template : `

    <div  *ngFor="#page of pages">
      <a [routerLink]="[page.name]">
        {{page.slug}}
      </a>
    </div>

    <router-outlet></router-outlet>
  `
})
@RouteConfig([
  {path : '/', name: 'Main', component: MainRoute, useAsDefault: true}  
])
export class UsersComponent{
  /**
  * some methods to configure the routes,
  */
}

UsersComponent 已为用户动态配置路由，

例如 . /alex ， /john 等，

由于路由来自子组件，路径看起来像 example.com/users/alex ， example.com/users/john 等 . 但我希望路径为 example.com/alex 和 example.com/john

我还想将与每个用户关联的组件加载到父级的 router-outlet . 在这里的示例中， App 的_28303332_使我可以摆脱用户列表 .

感谢您的任何帮助 .

以下是我的配置：Plunker

1. Define your App's RouteConfig like this

@RouteConfig([
  {
    path: '/',
    name: 'Home',
    component: HomeComponent,
    useAsDefault: true

  },
  {
    path: '/:user',
    name: 'User',
    component: PersonComponent
  },
  {
    path: '/users',
    name: 'Users',
    component: UsersComponent
  },
  {
    path: '/contact',
    name: 'Contact',
    component: ContactComponent
  }
])

2. Remove router.config and <router-outlet> from your UsersComponent

不要通过 RouteData 发送用户数据，因为您必须提前为每个用户定义路由，这不是必需/有效的 .

@Component({
  selector: 'my-app',
  template : `

    <div  *ngFor="#page of pages">
      <a [routerLink]="['User', {user: page.name}]">
        {{page.slug}}
      </a>
    </div>
  `,
  providers : [PagesService]
})
export class UsersComponent{
  pages = [];

  constructor(private pgSvc: PagesService, router: Router) {
  }
}

3. Structure your service to send data for a specific user

4. Update your PersonComponent to accomodate with these changes.

@Component({
  selector : 'person',
  template : `
  <div class="person-container">
    <h3>Person selected : <strong> {{data.get['user']}} </strong></h3>
  </div>
  `
})
class PersonComponent {
  constructor(public data: RouteParams) {

   // call your service here to get the user specific data by using 
    let userName = data.get('user');

   // yourService.getUserData(userName);
  }
  routerCanReuse(next, prev) {
    return false;
  }
}
