如何隐藏离子4选项卡只是为登录页面

Posted 2021-04-21

我正在开发一个带有标签的项目，但它应该只在用户登录后出现。

当app.routing.module.ts中的路由如下所示时，标签工作正常：

{ path: '', loadChildren: './tabs/tabs.module#TabsPageModule' }

但是当我像这样使用登录时：

{ path: '', loadChildren: './login/login.module#LoginPageModule' },
{ path: 'home', loadChildren: './tabs/tabs.module#TabsPageModule' }

它不起作用。

app.routing.module.ts

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

const routes: Routes = [
  { path: '', loadChildren: './login/login.module#LoginPageModule' },
  { path: 'home', loadChildren: './tabs/tabs.module#TabsPageModule' },
];

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

tabs.routing.module.ts

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { TabsPage } from './tabs.page';



const routes: Routes = [
  {
    path: 'home',
    component: TabsPage,
    children: [
      {
        path: '',
        redirectTo: '/home/(MyPlaces:MyPlaces)',
        pathMatch: 'full'
      },
      {
        path: 'MyPlaces',
        outlet: 'MyPlaces',
        loadChildren: '../MyPlaces/MyPlaces.module#MyPlacesPageModule'
      },
      {
        path: 'Messages',
        outlet: 'Messages',
        loadChildren: '../Messages/Messages.module#MessagesPageModule'
      }
    ]
  }
];

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

答案

导入TabsPageModule并将其放在app.module.ts上imports: [...]。这适合我。

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouterModule, RouteReuseStrategy } from '@angular/router';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

import { TabsPageModule } from './tabs/tabs.module';

@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [BrowserModule, IonicModule.forRoot(), AppRoutingModule, TabsPageModule],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})
export class AppModule {}

另一答案

经过这么多的尝试后，我发现这种方法永远不会像以前一样工作至少现在这个工作的唯一方法是不使用延迟加载代码就是这样：

app.routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { TabsPage } from './tabs/tabs.page'

const routes: Routes = [
  { path: '', loadChildren: './login/login.module#LoginPageModule' },
  { path: 'home', component: TabsPage },
];

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

app.module.ts

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { RouteReuseStrategy } from '@angular/router';

import { IonicModule, IonicRouteStrategy } from '@ionic/angular';
import { SplashScreen } from '@ionic-native/splash-screen/ngx';
import { StatusBar } from '@ionic-native/status-bar/ngx';

import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';
import { TabsPageModule } from './tabs/tabs.module';

@NgModule({
  declarations: [AppComponent],
  entryComponents: [],
  imports: [BrowserModule,
    IonicModule.forRoot(),
    AppRoutingModule,
    TabsPageModule
  ],
  providers: [
    StatusBar,
    SplashScreen,
    { provide: RouteReuseStrategy, useClass: IonicRouteStrategy }
  ],
  bootstrap: [AppComponent]
})
export class AppModule { }

请注意导入TabsPageModule。

tabs.routing.module.ts

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { TabsPage } from './tabs.page';
import { MyPlacePage } from '../MyPlaces/MyPlaces.Page';
import { MessagesPage } from '../Messages/Messages.Page';


const routes: Routes = [
  {
    path: 'home',
    component: TabsPage,
    children: [
      {
        path: '',
        redirectTo: '/home/(MyPlaces:MyPlaces)',
        pathMatch: 'full'
      },
      {
        path: 'MyPlaces',
        outlet: 'MyPlaces',
        component: MyPlacePage
      },
      {
        path: 'Messages',
        outlet: 'Messages',
        component: MessagesPage
      }
    ]
  }
];

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

tabs.module.ts

import { IonicModule } from '@ionic/angular';
import { NgModule } from '@angular/core';
import { CommonModule } from '@angular/common';
import { FormsModule } from '@angular/forms';

import { TabsPageRoutingModule } from './tabs.router.module';

import { TabsPage } from './tabs.page';
import { MyPlacesPageModule } from '../MyPlaces/MyPlaces.module';
import { MessagesPageModule } from '../Messages/Messages.module';

@NgModule({
  imports: [
    IonicModule,
    CommonModule,
    FormsModule,
    TabsPageRoutingModule,
    MyPlacesPageModule,
    MessagesPageModule
  ],
  declarations: [TabsPage]
})
export class TabsPageModule {}

另请注意，您需要使用href链接标签页而不是routerLiknk。
