Angular 2子应用程序,父/子,嵌套组件,嵌套路由器插座,设计/编码

标签: javascript angular

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,新的管理员组件将加载到新的路由器插座中。

但是...

Angular 2不允许超过1个路由器插座。因此,点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。

我在使用“bootstrap”加载后续组件时看到了一些SO帖子(较旧,可能已弃用),但我无法让它工作。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子应用程序部分正常工作?

非常感谢您分享您的Angular 2专业知识: - )

编辑:尝试以下建议的解决方案。无论我在何处放置路线,都在app.routes.ts基地或子应用admin.routes.ts中,无论我如何格式化routerLinks,我一直收到这个错误......

Cannot find route

再次编辑:以下是路由器和模板中的代码......

编辑5:它正在运作!

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,路由模块工作。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,然后在父母点击链接以使用自己的新路由器插件加载子应用。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。

需要注意的重点,至少在我的情况下,在子路由器插座中使用name="" attrib。这将导致“错误:无法匹配任何路线......”。 不要使用像我上面尝试过的路由模块,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......”。确保完全按照下面的admin.routes.ts中的设置设置子路由配置children: []。另请注意子路径中的RouterModule.forChild(router)。这些事情为我今天解决了这个问题。

答案 0 :(得分:13)

不确定您在哪里听说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,该管理模块将拥有包含侧边菜单栏的根组件和所有子路由的router-outlet

示例:

// 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}

        ]
    }
];

管理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。一个例子是并排两个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。

修改

对于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。根路由配置将加载到带有RouterModule.forRoot(routes)的根AppModule中,子路由在RouterModule.forChild(routes)的子模块中。

您的路线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):

// Admin Routes

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' },
   ....

// App Module

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

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

希望有所帮助。

答案 1 :(得分:1)

是的,有办法做到这一点。 您需要为路由器插座命名,如:

<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径:

{
    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'
        }
    ]
}
