问题描述

我正在使用角度延迟加载，无法在主要组件中显示 child1、child2 和 child3。

这是供您参考的代码

我要做的是在共享模块中的主要组件中显示 child1、child2 和 child3

import { NgModule } from '@angular/core';
import { BrowserModule } from '@angular/platform-browser';
import { APP_BASE_HREF, LocationStrategy, PathLocationStrategy } from '@angular/common';

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


@NgModule({
  declarations: [
    AppComponent,
  ],
  imports: [
    BrowserModule,
    AppRoutingModule,
    HomeModule
  ],
  providers: [],
  bootstrap: [AppComponent]

export class AppModule { }

export class HomeRoutingModule { }

—main.html

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

@Component({
  selector: 'app-main',
  templateUrl: './main.component.html'
})
export class MainComponent implements OnInit {

  constructor() { }

  ngOnInit(): void {
  }

}


--child1.html
<h1>i am child 1</h1>

--child2.html
<h1>i am child 2</h1>

--child3.html
<h1>i am child 3</h1>

我正在努力修复它。任何解决方案

解决方案

移除{ path: '**', component: HomeComponent }并AppRoutingModule看到魔法发生。

当您定义path: '**'它时，它意味着除了我之前定义的所有路径！
通过单击，您正在更改tochildComponents的路径和触发器，然后它会重新渲染 home 组件，您会陷入循环。homecustAppRoutingpath: **
