routerLink 无法导航到延迟加载模块

Question

我在导航到延迟加载模块中定义的组件时遇到问题。 组件

ListComponent

定义在路径

test

下（my-routing.module.ts - 延迟加载模块）。每当我单击

Test

按钮 (test.component.html) 时，我都会收到异常

NG04002: Cannot match any routes. URL Segment: 'test'.

为什么？

我的 app-routing.module.ts 看起来像这样：

import { NgModule } from '@angular/core';
import { RouterModule, Routes } from '@angular/router';
import { HomeComponent } from './components/home/home.component';
import { AboutComponent } from './components/about/about.component';
import { DashboardComponent } from './components/dashboard/dashboard.component';
import { AuthGuard } from './auth.gard';
import { ListComponent } from './list.component';
import { TestComponent } from './test/test.component';


const myModule = () => import('./my-routing/my-.module').then(x => x.MyRoutingModule);
const routes: Routes = [
  { path: '', component: TestComponent },
  { path: 'experiment', loadChildren: myModule },

];

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

我的 my-routing.module.ts 是：

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { ListComponent } from '../list.component';
import { TestComponent } from '../test/test.component';

const routes: Routes = [

  { path: 'test', component: ListComponent },

];

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

我的 test.component.html 看起来像这样：

<div class="container">
  <div class="row">
    
    <div class="col-1">
      <a [routerLink]="['test']"><button type="button" class="btn btn-primary">
          Test</button></a>
    </div>

  </div>
</div>

Answer 1

如果您阅读了您的 app.routing.ts，

{ path: 'experiment', loadChildren: myModule },

MyRoutingModule

中的所有路线都将以路径：“/experiment”开头

因此，将路径“test”更改为“experiment/test”。

<a [routerLink]="['experiment/test']">
    <button type="button" class="btn btn-primary">
        Test
    </button>
</a>

请注意，您可以将

[routerLink]

属性应用于

<button>

元素，而不需要

<a>

元素。

<button type="button" class="btn btn-primary" [routerLink]="['experiment/test']">
    Test
</button>
