带选项卡的Angular 6 RouterLink

Question

我有一个Angular 6延迟加载选项卡模板,可以正常工作.主页面有一个路由器插座,标签有二级路由器插座.但是,我无法在主菜单中创建显示标签页的routerLink.

此routerLink仅在标签页上尚未显示时才有效.例如

• 如果在测试页面:/ test
• 点击链接

• 正确链接到:tabs /(about:about)

  链接到标签页

如果已经在主页选项卡上(并单击链接),则最终的URL为:

/tabs/(about:about//home:home)

如何创建始终链接到以下内容的routerLink？

/tabs/(about:about)

我对这个打字稿有同样的行为:

this.router.navigate(['/tabs', { outlets: { about: ['about']}}]);

但是,这个打字稿正常工作:

this.router.navigateByUrl('/tabs/(about:about)');

app.component.html

<ion-app>
  <nav>
    <a [routerLink]="['/tabs', { outlets: { about: 'about' } }]">
      This link only works if NOT already on tab page.
    </a>
    <ion-button (click)="navigateByUrl()">This always works!</ion-button>
  </nav>
<router-outlet></router-outlet>
</ion-app>

APP-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';

const routes: Routes = [
  { path: '', loadChildren: './pages/tabs/tabs.module#TabsPageModule' },
  { path: 'test', loadChildren: './pages/test/test.module#TestPageModule' }
];
@NgModule({
  imports: [RouterModule.forRoot(routes, { enableTracing: true } )],
  exports: [RouterModule]
})
export class AppRoutingModule {}

tabs.router.module.ts

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';

import { TabsPage } from './tabs.page';
import { HomePage } from '../home/home.page';
import { AboutPage } from '../about/about.page';
import { ContactPage } from '../contact/contact.page';

const routes: Routes = [
  {
    path: 'tabs',
    component: TabsPage,
    children: [
      {
        path: 'home',
        outlet: 'home',
        component: HomePage
      },
      {
        path: 'about',
        outlet: 'about',
        component: AboutPage
      },
      {
        path: 'contact',
        outlet: 'contact',
        component: ContactPage
      }
    ]
  },
  {
    path: '',
    redirectTo: '/tabs/(home:home)',
    pathMatch: 'full'
  }
];

@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class TabsPageRoutingModule {}

在您的index.html 中，您应该添加以下行。

<base href="/"> 

根据您的根 URL，heref 部分可能具有不同的值。

现在在您的路由配置中编写路由配置，如下所示。

       const routes: Routes = [
       {
         path: 'tabs',
         component: TabsPage,
         children: [
          {
            path: 'home',
            outlet: 'home',
            component: HomePage
          },
          {
            path: '',
            redirectTo: 'home',
            pathMatch: 'full'
          },
          {
            path: 'about',
            outlet: 'about',
            component: AboutPage
          },
          {
            path: 'contact',
            outlet: 'contact',
            component: ContactPage
          }
        ]
      },
      {
        path: '',
        redirectTo: 'tabs',
        pathMatch: 'full'
      }
    ];
