Angular 2子应用程序，父/子，嵌套组件，嵌套路由器插座，设计/编码-Java 学习之路

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

Main app screen

当您单击顶级菜单routerLinks中的项目时，新组件将加载到主视图路由器插座中 . 其中一个链接加载一个新的“管理”模块/组件，它有自己的路由和新的路由器插座......

Admin app screen

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插座中 .

但...

Angular 2不允许超过1个路由器插座 . 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插座视图 .

我've seen some SO posts (older, maybe deprecated) on using 861254 to load subsequent Components, but I can' t得到它的工作 . 我甚至不能 import { bootstrap } from 'anywhere at all, nothing works' . 所以也许这不是这样做的方式 .

如何让Admin子应用程序部分工作？

非常感谢您分享您的Angular 2专业知识:-)

EDIT: Trying suggested solutions below. 无论我把路线放在哪里，在基础app.routes.ts或子应用程序admin.routes.ts中，无论我如何格式化routerLinks，我都会收到此错误...

Cannot find route

EDIT AGAIN: 这是路由器和模板中的代码......

EDIT 5: IT'S WORKING!

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 . 泰勒和我一起工作很多，所以我接受了他的回答 . 谢谢泰勒的帮助！

以下是如何使用自己的路由器插座设置父应用程序，然后在父级单击链接以使用自己的新路由器插件加载子应用程序 . 子应用程序加载/替换父应用程序路由器插座 .

父app模块或路由中没有什么特别之处 . 他们就是我在这篇文章之前的方式 .

The important points to note ，至少在我今天的情况下，不要在子路由器插座中使用 name="" attrib . 这将导致"Error: Cannot match any routes..." . 不要像我上面尝试的那样使用路由模块，这也会导致"Error: Cannot match any routes..." . 不要在路由中使用 outlet: 'blah' ，这也会导致"Error: Cannot match any routes..." . 确保完全按照下面的admin.routes.ts中的设置设置子路由配置 children: [] . 另外，请注意子路径中的 RouterModule.forChild(router) . 这些事情为我今天解决了这个问题 .

不知道你在哪里听说Angular2不允许超过1 router-outlet . 我在一个大型应用程序中使用了几个 .

您的主app.component将有一个 router-outlet 来处理根路由 . 如果您的某个路由延迟加载管理模块，该管理模块将具有包含侧面菜单栏的根组件和所有子路由的 router-outlet .

例：

//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 router-outlet .

然后管理员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栏菜单和 router-outlet 以显示子组件 .

您也可以命名为 router-outlets . 一个例子是两个 router-outlet 并排：

<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>

或者用以下内容清除内容：

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

有关详细信息，请参阅docs或此article .

希望有所帮助 .

Edit

为延迟加载的子项使用路由配置时，请确保在模块中正确加载路由配置 . 根路由配置将在带有 RouterModule.forRoot(routes) 的根AppModule中加载，子路由在带有 RouterModule.forChild(routes) 的子模块中 .

您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）：

//管理员路线

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（延迟加载管理模块）

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),
  ]
   ...

希望有所帮助 .

是的，有办法做到这一点 . 您需要将路由器插座命名为：

<router-outlet name="child1"></router-outlet>

<router-outlet name="child2"></router-outlet>

在路由器内部，您需要定义路由器应该路由使用的路由器：

{
    path: 'home',  // you can keep it empty if you do not want /home
    component: 'appComponent',
    children: [
        {
            path: '',
            component: childOneComponent,
            outlet: 'child1'
        },
        {
            path: '',
            component: childTwoComponent,
            outlet: 'child2'
        }
    ]
}
