Angular2 路由的每个主题都有一个固定的导航栏

<nav>
    <a [routerLink]="['/component-one']">Component One</a>
    <a [routerLink]="['/component-two']">Component Two</a>
</nav>
<router-outlet></router-outlet>

所以基本上当点击组件一的链接时，这个组件将呈现在下面<nav></nav>

我需要的是当您单击组件一时，完整视图（整页）更改为组件一的视图（因此没有<nav></nav>）

我试着把它放在<router-outlet>一个单独的@Component

// view.component.ts    
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

@Component({
    selector: 'view',
    template:`<router-outlet></router-outlet>`,
    directives: [ROUTER_DIRECTIVES]
})

export class ViewComponent {

}

接着

// home.component.ts
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

@Component({
    selector: 'home',
    template: `
        <nav>
            <a [routerLink]="['/component-one']">Component One</a>
            <a [routerLink]="['/component-two']">Component Two</a>
        </nav>
        <router-outlet></router-outlet>
    `,
    directives: [ROUTER_DIRECTIVES]
})

export class HomeComponent {

}

App 组件如下所示：

import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

import { HomeComponent } from './containers/home.component';

@Component({
  moduleId: module.id,
  selector: 'app-root',
  template: `
  <h1>{{title}}</h1>
  <view></view>
  <home></home>
  `,
  styleUrls: ['app.component.css'],
  directives:  [HomeComponent, ROUTER_DIRECTIVES]
})
export class AppComponent {
  title = 'app works';
}

也试过<home>放进去<view>，但什么也没有

总是得到同样的错误：

错误：找不到加载“OneComponent”的主要出口

任何人都可以帮助我吗？谢谢！

编辑

// app.routes.ts
import { provideRouter, RouterConfig } from '@angular/router';

import { ViewComponent } from './containers/view.component';
import { HomeComponent } from './containers/home.component';
import { OneComponent } from './containers/one.component';
import { TwoComponent } from './containers/two.component';

const routes: RouterConfig = [
    {
        path: '',
        redirectTo: '',
        pathMatch: 'full'
    },
    { 
        path: '', 
        component: HomeComponent, 
    },
    { 
        path: 'one', 
        component: OneComponent 
    },
    { 
        path: 'two', 
        component: TwoComponent 
    }
];

export const appRouterProviders = [
    provideRouter(routes)
];

您的 routerLinks 中有错误的路径： 

<nav>
  <a [routerLink]="['/component-one']">Component One</a>
  <a [routerLink]="['/component-two']">Component Two</a>
</nav>

与您的路由器配置路径相比

 { 
    path: 'one', 
    component: OneComponent 
},
{ 
    path: 'two', 
    component: TwoComponent 
}

将它们修复为：

<nav>
  <a [routerLink]="['/one']">Component One</a>
  <a [routerLink]="['/two']">Component Two</a>
</nav>

谢谢你们的快速反应……你们都给我指出了正确的方向。

解决方案：

主组件只需要另一个组件来呈现视图（<view></view>）

// app.component.ts
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

import { ViewComponent } from './containers/view.component';

@Component({
  moduleId: module.id,
  selector: 'app-root',
  template: `
  <h1>
    {{title}}
  </h1>
  <view></view>
  `,
  directives:  [ViewComponent, ROUTER_DIRECTIVES]
})
export class AppComponent {
  title = 'app works!';
}

视图组件只包含<router-outlet></router-outlet>

// view.component.ts
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

@Component({
    selector: 'view',
    template:`<router-outlet></router-outlet>`,
    directives: [ROUTER_DIRECTIVES]
})

export class ViewComponent {  
}

路线必须正确（哎呀）

// app.routes.ts
import { provideRouter, RouterConfig } from '@angular/router';

import { HomeComponent } from './containers/home.component';
import { OneComponent } from './containers/one.component';
import { TwoComponent } from './containers/two.component';

const routes: RouterConfig = [
    {
        path: '',
        redirectTo: '/home',
        pathMatch: 'full'
    },
    { 
        path: 'home', 
        component: HomeComponent, 
    },
    { 
        path: 'one', 
        component: OneComponent 
    },
    { 
        path: 'two', 
        component: TwoComponent 
    }
];

export const appRouterProviders = [
    provideRouter(routes)
];

然后它只是构建视图（页面）

// home.components.ts
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

import { NavigationComponent } from './navigation.component';

@Component({
    selector: 'home',
    template: `
        <div><h1>{{title}}</h1></div>
        <navigation></navigation>
    `,
    directives: [ROUTER_DIRECTIVES, NavigationComponent]
})

export class HomeComponent {
    title = 'This is home';
}

HomeComponent 中使用的导航组件：

// navigation.component.ts
import { Component } from '@angular/core';
import { ROUTER_DIRECTIVES } from '@angular/router';

@Component({
    selector: 'navigation',
    template: `
        <nav>
            <a [routerLink]="['/one']">Comp one</a>
            <a [routerLink]="['/two']">Comp two</a>
        </nav>
    `,
    directives: [ROUTER_DIRECTIVES]
})

export class NavigationComponent {
}

和

// one.component.ts
import { Component } from '@angular/core';

import { ROUTER_DIRECTIVES } from '@angular/router';

@Component({
    selector: 'one',
    template: `
        <p>ONE: {{message}}</p>
        <a [routerLink]="['/two']">GOTO Comp two</a>
    `,
    directives: [ROUTER_DIRECTIVES]
})

export class OneComponent {
    message = 'ONE comp here';
}

和

// two.component.ts
import { Component } from '@angular/core';

import { ROUTER_DIRECTIVES } from '@angular/router';

@Component({
    selector: 'two',
    template: `
        <p>TWO: {{message}}</p>
        <a [routerLink]="['/one']">GOTO Comp one</a>
    `,
    directives: [ROUTER_DIRECTIVES]
})

export class TwoComponent {
    message = 'TWO here';
}

将您的路由移动到自己的组件

<nav>
    <a [routerLink]="['/component-one']">Component One</a>
    <a [routerLink]="['/component-two']">Component Two</a>
</nav>

并将它们注入您想要拥有它们的组件上，当您路由到该组件时，您将看到导航，当您转到另一个组件时，它们将从那里删除。

上面或下面的所有内容都<router-outlet></router-outlet> 将在每个页面中可用
