javascript - Angular 2 子应用、父/子、嵌套组件、嵌套路由器 socket 、设计/编码

Question

我有一个 Angular 2 应用程序。主屏幕(应用程序？)看起来像这样......

当您单击顶部菜单 routerLinks 中的项目时，新组件将加载到主视图路由器 socket 中。其中一个链接加载了一个新的“管理”模块/组件，它有自己的路由和新的路由器导出......

然后当您单击左侧导航栏中的 routerLinks 时，新的管理组件将加载到新的路由器 socket 中。

但是……

Angular 2 不允许超过 1 个路由器 socket 。因此，单击左侧导航栏中的任何 routerLink 只会替换整个初始路由器导出 View 。

我看过一些关于使用“bootstrap”加载后续组件的 SO 帖子(较旧的，可能已弃用)，但我无法让它工作。我什至无法从'任何地方导入{ bootstrap }，没有任何作用'。所以也许这不是执行此操作的方法。

如何让 Admin 子应用部分正常工作？

非常非常感谢您分享您的 Angular 2 专业知识:-)

编辑:尝试下面建议的解决方案。无论我将路由放在哪里，在基础 app.routes.ts 或子应用 admin.routes.ts 中，无论我如何格式化routerLinks，我不断收到此错误...

再次编辑:这是路由器和模板中的代码...

编辑 3: 尝试将 RouterModule.forRoot 更改为 RouterModule.forChild，遗憾的是，同样的错误:-/

编辑 4: 将路由转换为使用 2 个路由模块。希望这可能会有所作为，但同样的错误。

编辑 5:它正在运行!

删除了路由模块，根据 Tyler 的建议返回到导出路由配置。他是对的，路由模块不起作用。泰勒和我一起工作了很多，所以我接受他的回答。谢谢泰勒的帮助!

这里介绍了如何使用自己的路由器 socket 设置父应用程序，然后在父应用程序上单击一个链接以加载具有自己的新路由器 socket 的子应用程序。子应用加载/替换父应用路由器导出。

父应用模块或路由中确实没有什么特别之处。它们就是我在这篇文章之前拥有它们的方式。

需要注意的要点，至少在我今天的情况下，不要在子路由器中使用 name="" 属性-导出。这将导致“错误:无法匹配任何路由...”。 不要像我在上面尝试的那样使用路由模块，这也会导致“错误:无法匹配任何路由...”。 不要在路由中使用outlet: 'blah'，这也会导致“错误:无法匹配任何路由...”。确保完全按照下面在 admin.routes.ts 中看到的方式设置子路由配置 children: []。另外，请注意子路由中的 RouterModule.forChild(router)。这些东西今天为我解决了这个问题。

不确定您在哪里听说 Angular2 不允许超过 1 个 router-outlet。我在大型应用程序中使用了多个。

您的主要 app.component 将有一个 router-outlet 来处理根路由。如果您的其中一条路由延迟加载了管理模块，则该管理模块将拥有包含侧边菜单栏和所有子路由的 router-outlet 的根组件。

例子:

//app.routes

export const ROUTES: Routes = [
    // Main redirect
    { path: '', component: MainViewComponent },

    {
        path: 'admin',
        loadChildren: './admin/admin.module#AdminModule'
    }
]

您的 MainViewComponent 可以包含顶部导航栏和一个 router-outlet。

然后 Admin 路由器配置可能如下所示:

export const routes: Routes = [
    {
        path: '',
        component: AdminComponent,
        children: [
            { path: '', component: Component1},
            { path: 'component2', component: Component2}

        ]
    }
];

Admin 模块中的根组件可能包含侧边栏菜单和一个router-outlet 以显示子组件。

你也可以命名为 router-outlets。一个例子是并排放置两个 router-outlet:

<router-outlet></router-outlet>
<router-outlet name="popup"></router-outlet>

您的路由器配置如下所示:

{
  path: 'compose',
  component: ComposeMessageComponent,
  outlet: 'popup'
},

你会像这样使用它:

<a [routerLink]="[{ outlets: { popup: ['compose'] } }]">Contact</a>

或者用这个清除内容:

this.router.navigate([{ outlets: { popup: null }}]);

参见 docs或者这个 article了解更多详情。

希望对您有所帮助。

当为延迟加载的 child 使用路由配置时，请确保您的路由配置已正确加载到您的模块中。根路由配置将通过 RouterModule.forRoot(routes) 加载到根 AppModule 中，子路由通过 RouterModule.forChild(routes) 加载到子模块中。

你的路由配置和模块需要看起来像这样(不要创建一个单独的模块来保存路由配置):

//管理路由

export const adminRoutes: Routes = [
    {
        path: 'admin', component: AdminComponent,
        children: [
            { path: 'world', component: AdminWorldComponent, outlet: 'admin-app' }
            , { path: 'module', component: AdminModuleComponent, outlet: 'admin-app' }
            , { path: 'region', component: AdminRegionComponent, outlet: 'admin-app' }
        ]
    }
];

//管理模块:

import { adminRoutes } from './admin.routes';

@NgModule({
  imports: [
    ...
    RouterModule.forChild(adminRoutes),
  ]
   ...

//App Routes(延迟加载Admin模块)

export const appRoutes: Routes = [
   { path: 'admin', loadChildren: './admin/admin.module#AdminModule' },
   ....

//应用模块

import { appRoutes } from './app.routes';

@NgModule({
  imports: [
    ...
    RouterModule.forRoot(appRoutes),
  ]
   ...

希望对您有所帮助。
