Question

我已经在Angular应用程序中实现了延迟加载。从app.routes文件中，我加载了Login和Dashboard模块，直到此时一切都可以在延迟加载中正常工作。尝试使用loadChildrens（即子级中的子级）将其他子级路由加载到仪表板.routes时出现问题。

app.module

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

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

app-routing.module.ts

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


const routes: Routes = [
  {
    path: 'login',
    loadChildren: 'app/modules/login/login.module#LoginModule'
  },
  {
    path: 'dashboard',
    loadChildren: 'app/modules/dashboard/dashboard.module#DashboardModule'
  },
  { path: '**', redirectTo: 'login', pathMatch: 'full' }
];

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

dashboard.module.ts

import { NgModule } from "@angular/core";
import { MainRoutingModule } from "@app/modules/main/main-routing.module";
import { MainLayoutComponent } from "@app/modules/main/views/main-layout/main-layout.component";
import { BlankComponent } from '../blank/blank.component';

@NgModule({
  imports: [DashboardRoutingModule],
  declarations: [DashboardComponent]
})
export class DashboardModule { }

dashboard-routing.module.ts

import { NgModule } from '@angular/core';
import { Routes, RouterModule } from '@angular/router';
import { DashboardComponent } from '../blank/blank.component';

const routes: Routes = [
  {
    path: '',
    component: DashboardComponent,
    children: [
      {
        path: 'clients',
        loadChildren: './../clients/clients.module#CLientsModule'
      },
      {
        path: 'users',
        loadChildren: './../users/users.module#UsersModule'
      },
      { path: '', redirectTo: '/users', pathMatch: 'full' }
    ]
  }
];
@NgModule({
  imports: [RouterModule.forChild(routes)],
  exports: [RouterModule]
})
export class DashboardRoutingModule { }

clients.module

import { NgModule } from "@angular/core";

import { CommonModule } from '@angular/common';
import { ClientsComponent } from './clients.component';
import { CLientsRoutingModule } from './clients-routing.module';


@NgModule({
  imports: [
    CommonModule,
    CLientsRoutingModule
  ],
  declarations: [ClientsComponent]
})
export class CLientsModule { }

clients.routing

import { Routes, RouterModule } from '@angular/router';
import { NgModule } from '@angular/core';
import { CLientsComponent } from './clients.component';

const routes: Routes = [
    {
      path: '',
      component: CLientsComponent
    }
  ];
  @NgModule({
    imports: [RouterModule.forChild(routes)],
    exports: [RouterModule]
  })
  export class ClientsRoutingModule { }

Answer 1

当我没有指定路由路径时，我也出现了这个错误。

Answer 2

您正在尝试对未定义的变量调用split方法。

不看代码就很难告诉您到底出了什么问题，但是请确保在调用split方法之前定义了变量。

如果您不能保证会有值，您还可以在调用周围添加if条件，以测试变量中是否存储有值。
