路由有效，但未显示数据

Question

我正在从角度8的懒惰加载中加载两个页面，页面已正确重定向，但页面上未显示数据。

下面是我的一些文件

app.module.ts

template<class Elem>
iterator my_list<Elem>::begin(){
return iterator();
}

app.component.ts

import { BrowserModule } from '@angular/platform-browser';
import { NgModule } from '@angular/core';
import { AppRoutingModule } from './app-routing.module';
import { AppComponent } from './app.component';

@NgModule({
  declarations: [
    AppComponent
  ],
  imports: [
    BrowserModule,
    AppRoutingModule
  ],
  providers: [],
  bootstrap: [AppComponent]
})
export class AppModule { }

app.component.html

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

@Component({
  selector: 'app-root',
  templateUrl: './app.component.html',
  styleUrls: ['./app.component.css']
})
export class AppComponent {
  title = 'crm-pj';
}

app-routing.module.ts

stateComp.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
const routes: Routes = [
    { path: 'state', loadChildren: () => import('./state/stateModule').then(m => m.stateModuleCls) },
    { path: 'city', loadChildren: () => import('./city/cityModule').then(m => m.cityModuleCls) },
    {
      path: '',
      redirectTo: '',
      pathMatch: 'full'
    }
];

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


stateModule.ts

//import {BrowserModule} from "@angular/platform-browser";
import {NgModule} from "@angular/core";
import {stateCompCls} from './stateComp';
@NgModule({
    imports : [],
    declarations : [stateCompCls],
    bootstrap : [stateCompCls]
})

export class stateModuleCls{

}

state.html

import {Component} from '@angular/core';
@Component({
    selector :'app-root',
    templateUrl : 'state.html',
})

export class stateCompCls{

}

当我重定向到状态重定向时可以正常工作，但是数据“状态模块”显示的城市不一样。

Answer 1

尝试在stateModuleCls中导入appModule。
