Question

我试图简化客户网站背后的代码，因为有一些无关的代码。这样做，导航菜单（bootstrap）不再有效？它似乎在屏幕外，我不知道为什么或如何解决它。

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

//Layouts
import { FullLayoutComponent } from './layouts/full-layout.component';
import { SimpleLayoutComponent } from './layouts/simple-layout.component';

export const routes: Routes = [
  {
    path: '',
    redirectTo: '/login_Register',
    pathMatch: 'full',
  },
  {
    path: '',
    component: SimpleLayoutComponent,
    data: {
      title: 'people'
    },
    children: [
      {
        path: 'people',
        loadChildren: './people/people.module#PeopleModule'
      }
    ]
  }
];

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

Bootstrap 3代码确实不能与Bootstrap 4 css一起使用。 Bootstrap 4几乎完全重写了Bootstrap 3.因此，几乎所有内容都已更改。

以下是Bootstrap 4导航栏的工作原理：

<nav class="navbar navbar-expand-lg navbar-light bg-light">
    <a class="navbar-brand" href="#">Navbar</a>
    <button class="navbar-toggler" type="button" data-toggle="collapse" data-target="#navbarSupportedContent" aria-controls="navbarSupportedContent" aria-expanded="false" aria-label="Toggle navigation">
        <span class="navbar-toggler-icon"></span>
    </button>

    <div class="collapse navbar-collapse" id="navbarSupportedContent">
        <ul class="navbar-nav mr-auto">
            <li class="nav-item active">
                <a class="nav-link" href="#">Home <span class="sr-only">(current)</span></a>
            </li>
            <li class="nav-item">
                <a class="nav-link" href="#">Link</a>
            </li>
            <li class="nav-item dropdown">
                <a class="nav-link dropdown-toggle" href="#" id="navbarDropdown" role="button" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
                    Dropdown
                </a>
                <div class="dropdown-menu" aria-labelledby="navbarDropdown">
                    <a class="dropdown-item" href="#">Action</a>
                    <a class="dropdown-item" href="#">Another action</a>
                    <div class="dropdown-divider"></div>
                    <a class="dropdown-item" href="#">Something else here</a>
                </div>
            </li>
            <li class="nav-item">
                <a class="nav-link disabled" href="#">Disabled</a>
            </li>
        </ul>
        <form class="form-inline my-2 my-lg-0">
            <input class="form-control mr-sm-2" type="search" placeholder="Search" aria-label="Search">
            <button class="btn btn-outline-success my-2 my-sm-0" type="submit">Search</button>
        </form>
    </div>
</nav>

注意：开始时没有navbar-default和navbar-toggleable-*个类。此外，保持HTML有效是个好主意。（你的一些人不是）

Bootstrap 4导航栏参考：

移动菜单上的导航菜单很古怪？
