路由角4/5隐藏组件

Question

新的路由与角4/5,我在他们的网站上遵循角度教程.我有一个角度应用程序,我希望能够有两个单独的页面.现在主页是localhost:8870/dr3-interface,我想要一个新组件的新页面localhost:8870/dr3-interface/manage_cycles_instances

我的问题是,当我点击我的链接时,Manage cycles instances它会显示我的所有app.component组件,而不仅仅是我决定在我的组件上显示的组件/manage_cycles_instances.我试图隐藏它们*ngIf但没有结果.有任何想法吗？

app.component.html:

<div style="text-align:left">
  <h1>{{ title }}</h1>
</div>

<nav>
  <a routerLink="/manage_cycles_instances" routerLinkActive="active"> Manage cycles instances</a>
</nav>
<router-outlet></router-outlet>

<div *ngIf="router = '/dr3-interface'">
  <h2><d-table></d-table></h2>
</div>
<br/>
<form-upload></form-upload>
<br/>
<list-upload></list-upload>

app-routing.module.ts:

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

import { DataTableComponent }   from './datatable/data-table.component';


const appRoutes: Routes = [
  { path: 'manage_cycles_instances', component: DataTableComponent },
  /* TO DO : page error
  { path: '**', component: ... }
  */
];

@NgModule({
  imports: [
    RouterModule.forRoot(
      appRoutes,
      { enableTracing: true } // <-- debugging purposes only
    )
  ],
  exports: [
    RouterModule
  ]
})
export class AppRoutingModule {}

app.module.ts:

import { BrowserModule } from '@angular/platform-browser';
import { BrowserAnimationsModule } from '@angular/platform-browser/animations';
import { NgModule } from '@angular/core';
import { HttpClientModule } from '@angular/common/http';
import { FormsModule, ReactiveFormsModule } from '@angular/forms';

import {
 //all material modules
} from '@angular/material';

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

import { DataTableComponent } from './datatable/data-table.component';
import { DetailsUploadComponent } from './upload/details-upload/details-upload.component';
import { FormUploadComponent } from './upload/form-upload/form-upload.component';
import { ListUploadComponent } from './upload/list-upload/list-upload.component';

@NgModule({

  imports: [
    BrowserModule,
    AppRoutingModule,
    BrowserAnimationsModule,
    HttpClientModule,
    //material modules
  ],
  declarations: [
    AppComponent,
    DataTableComponent,
    DetailsUploadComponent,
    FormUploadComponent,
    ListUploadComponent
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule {
}

你的路线应该是这样的:

const appRoutes: Routes = [
  { path: 'dr3-interface', component: DrThreeComponent, children: [ // I don't know which component to use for this route
    { path: 'manage_cycles_instances', component: DataTableComponent },
  ]}, 
];

因为您希望拥有嵌套路由,所以应该创建嵌套路由.请注意,你DrThreeComponent应该有一个router-outlet,因为它有孩子.

您不需要在代码中使用条件,因为路由器将处理组件的显示.

说明:

首先要有一个index.html文件.它通常只在身体中包含一个标签app-root.此标记将由您的bootstraped组件替换,通常是这样AppComponent.

如果要路由应用程序,则需要使用路由器.需要几个步骤:

1 - 将路由器插座标签放在将路由其他人的组件中(此处为app组件)

2 - 创建你的路线(你做到了,我在答案中纠正了它).

3 - 如果是子路由(由斜线分隔的路由,与您的路由一样),请在每个父组件中放置一个路由器插座标签,并将一个children属性放入相应的路由中.

在你的情况下,如果我们要做一棵树,这将是这样的:

index.html
  |
  |--app component (with router outlet)
       |
       |--DrThree component (with router outlet)
            |
            |--ManageCycles component

所以基本上,索引会显示应用程序,然后应用程序将显示DrThree,然后DrThree将显示ManageCycles.
