我有一个主router-outlet
,用于显示登录屏幕(/login
)和主要内容屏幕(登录后显示)(/main
)。
用户在内容屏幕上,我想在顶部显示导航栏,有2个选项(例如,“概述”,“洞察”)。此导航栏对OverviewComponent
和InsightsComponent
在此导航栏下方,我想显示另一个路由器插座,它会根据用户在导航栏中的点击次数加载OverviewComponent
或InsightsComponent
。如果我将'/ overview'和/'insights'作为路线,它将直接显示相应的组件,但不会显示导航栏。
以下是我当前的路由配置(这不对):
const appRoutes: Routes = [
{ path: 'main', component: MainComponent},
{ path: 'overview', component: OverviewComponent},
{ path: 'insights', component: InsightsComponent },
{ path: 'login', component: LoginComponent },
{ path: '',
redirectTo: '/login',
pathMatch: 'full'
},
{ path: '**', component: PageNotFoundComponent }
];
如果我们能够在angular2 angular4中实现这一点,请告诉我。我正在使用以下版本:
"@angular/core": "^4.0.0"
"@angular/router": "^4.0.0"
"@angular/cli": "1.0.1"
******************尝试2 - 仍然没有工作******************
const appRoutes: Routes = [
{ path: 'main',
children: [
{ path: '', component: MainComponent },
{ path: 'overview', component: OverviewComponent },
{ path: 'insights', component: InsightsComponent },
]
},
{ path: 'login', component: LoginComponent },
{ path: '',
redirectTo: '/login',
pathMatch: 'full'
},
{ path: '**', component: PageNotFoundComponent }
];
*******尝试2 - 包含所有组件的Sudo代码 - 仍然无效*******

因此,如果我得到正确的问题,您希望最初拥有登录屏幕,并且在用户登录后,您希望他看到/主显示导航的位置。登录屏幕和主应用程序都应该有不同的布局。
我们有类似的情况并使用LayoutComponent。这是简化的例子。
// This is main component that get's bootstrapped that has 'top-level' router.
@Component({selector: 'app', template: '<router-outlet></router-outlet>'})
class AppComponent {}
// main router config
// Here AuthModule has router with login and logout configured and LoginGuard
// redirect the user to /auth/login when she is not authenticated.
// We're using lazy-loading but you can use direct component instead
export const APP_ROUTES: Routes = [
{path: '', redirectTo: 'main', pathMatch: 'full'},
{path: 'auth', loadChildren: '../modules/+auth/auth.module#AuthModule'},
{
path: '',
component: LayoutComponent,
canActivate: [LoginGuard],
children: [
{path: 'main', loadChildren: '../modules/+main/main.module#MainModule'}
]
}
];
// AuthModule/LoginComponent has own template and it will be rendered
// into 'top-level' router-outlet.
// LayoutComponent
// Here you define your main application layout that can include navigation
// and anything else that are global to the app. It has another router-outlet
// that get rendered when the layout is accessible (which in this case when the user is authenticated).
@Component({
selector: 'app-layout',
template: `
<div id="wrapper">
<app-sidebar></app-sidebar>
<div id="page-wrapper" class="gray-bg dashboard-1" adjust-content-height>
<router-outlet></router-outlet>
</div>
</div>
<notifications></notifications>
<error-modal></error-modal>
`
})
export class LayoutComponent {}
// Auth/LoginComponent can have its own template that will have different layout from the main application
所以流程就是这样:
希望有所帮助。

我想我会收集你想要达到的目标。我是否可以建议您使用变量来模拟某种状态更改,并将其分配给组件视图。 让你的app.component.html只包含一个路由器插座。 创建一个复制现有component.html的新main.component.html
`<app-header></app-header>`
替换with * (click)="handleChange(<linkValue>)'"
所以每个链接看起来如下。
<ul class="nav navbar-nav"> <li class=""><a href="/main/overview">OVERVIEW</a></li>
handleChange
方法:
声明currentLink - public currentLink string;
// or
public currentLink: string = '<a default value>';
public handleChange(link: string) {
this.currentLink = link;
}
创建一个view.component。
示例选择器<view [link]='currentLink'></view>
给视图组件一个
@Input() public link: string;
back to view.component.html
<div id="overview" *ngIf="link = 'overview'">overview content</div>
<div id="main" *ngIf="link = 'main'">overview content</div>
然后,您可以将它们重构为单独的子组件。
概述: 您正在使app-header成为处理“link”变量的全局组件。我建议看看ngRx或一般的app-state方法。因为这可以是管理UI的好方法。
