Question

嗨，我输入

时无法访问我所指的子路线

localhost:4200/general-managment/list-site

这不会转到列表站点的HTML。

这是我的list.component.ts：

import { Component, OnInit } from '@angular/core';
import {ActivatedRoute, Router} from '@angular/router';

@Component({
   selector: 'app-list',
  templateUrl: './list.component.html',
  styleUrls: ['./list.component.scss']
})
export class ListComponent implements OnInit {
 showlist = true;
   constructor(private router: Router,
          private route: ActivatedRoute) { }

  ngOnInit() {
   }
  siteList() {
    this.router.navigate(['list-site'] , {relativeTo: this.route});
    this.showlist = false;
 }

}

在this.router.navigate(['list-site'] , {relativeTo: this.route});中，我尝试了/list-site和./list-site和../list-site，但是它不起作用

这是我的app-routing.service.ts：

 import {Routes, RouterModule} from '@angular/router';
 import {HomeComponent} from './home/home.component';
 import {NgModule} from '@angular/core';
 import { LogoutComponent } from './header/logout/logout.component';
 import {GeneralManagementComponent} from 
        './home/generalmanagement/generalmanagement.component';
 import {SiteComponent} from './home/general- 
      management/list/site/site.component';

const appRoutes: Routes = [
  {path: '', component: HomeComponent},
  {path: 'log-out', component: LogoutComponent},
  {path: 'general-management' , component: GeneralManagementComponent , 
      children : [
      {path: 'list-site' , component: SiteComponent}
           ]}
   ];

@NgModule({
  imports: [
    RouterModule.forRoot(appRoutes)
  ],
  exports: [
    RouterModule
  ],
})

export class AppRoutingService {
}

这是我的HTML文件：

  <button> id="close-image" type="button" class="box" (click)="siteList()"> 
   <img class="list-content" src="assets/imgs/download.jpg">Site
   </button>

我使用角度6。我该如何解决

我在这里使用控制台：

siteList() {
    console.log(this.router.navigate(['list-site']));
    this.router.navigate(['list-site'] , {relativeTo: this.route});
    this.showlist = false;
  }

这就是我所看到的：

__proto__:
catch: ƒ (onRejected)
arguments: (...)
caller: (...)
length: 1
name: ""
prototype: {constructor: ƒ}
__proto__: ƒ ()
[[FunctionLocation]]: zone.js:966
[[Scopes]]: Scopes[4]
finally: ƒ (onFinally)
arguments: (...)
caller: (...)
length: 1
name: ""
prototype: {constructor: ƒ}
__proto__: ƒ ()
[[FunctionLocation]]: zone.js:969
[[Scopes]]: Scopes[4]
then: ƒ (onFulfilled, onRejected)
arguments: (...)

我只需要创建一个新的div，然后在新的div中调用 router-outlet ，即可正常工作：）

Answer 2

因为当您调用list-site路由时，它会尝试生成SiteComponent，但是您的组件称为ListComponent。

这就是您的app-routing.service.ts的样子：

 import {Routes, RouterModule} from '@angular/router';
 import {HomeComponent} from './home/home.component';
 import {NgModule} from '@angular/core';
 import { LogoutComponent } from './header/logout/logout.component';
 import {GeneralManagementComponent} from 
        './home/generalmanagement/generalmanagement.component';
 import {ListComponent} from './home/general- 
      management/list/site/site.component';

const appRoutes: Routes = [
  {path: '', component: HomeComponent},
  {path: 'log-out', component: LogoutComponent},
  {path: 'general-management' , component: GeneralManagementComponent , 
      children : [
      {path: 'list-site' , component: ListComponent}
           ]}
   ];

如何通过本地主机访问子路由？
