Question

我正在构建一个有角度的5应用程序，而且我在玩路线方面遇到了麻烦......

我有2个主布局，每个布局都有如下所示的子路径：

SiteLayoutComponent - HomeComponent AppLayoutComponent - ContactComponent

我的问题在于默认路由，当应用程序第一次加载时，使用空URL，路由器必须重定向到Home Component，它具有子路由＆＃34; SiteLayoutComponent＆＃34;，这里的问题是它只加载HomeComponent而不是＃34; SiteLayoutComponent＆＃34;它有一个<navbar-component>。它仅在浏览器中输入/ home时有效。以下是我的路线：

const appRoutes: Routes = [

{
    path: '',
    redirectTo: 'home',
    pathMatch: 'full'
},
//Site routes goes here        
{
    path: 'home',
    component: SiteLayoutComponent,
    children: [
        { 
            path: '', 
            component: HomeComponent 
        }
    ]
},
//App routes goes here
{
    path: 'app',
    component: AppLayoutComponent,
    children: [
        { path: 'contact', component: ContactComponent }
    ]
},
//No layout routes    
{
    path: '**', redirectTo: 'home'
}

];

export const routing = RouterModule.forRoot（appRoutes，{enableTracing：true}）;

它应该显示带有SiteLayoutComponent的HomeComponent（其中包含导航栏），但在键入类似＆＃34; http://localhost:4200/home＆＃34;的网址时，它只显示SiteLayoutComponent（包含导航栏）。 / p>

SiteLayoutComponent

<layout-site-navbar></layout-site-navbar>
<router-outlet></router-outlet>

SiteNavbarComponent

<nav class="navbar navbar-default">
<div class="container-fluid">
  <!-- Brand and toggle get grouped for better mobile display -->
  <div class="navbar-header">
    <button type="button" class="navbar-toggle collapsed" data-toggle="collapse" data-target="#bs-example-navbar-collapse-1" aria-expanded="false">
      <span class="sr-only">Toggle navigation</span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
      <span class="icon-bar"></span>
    </button>
    <a class="navbar-brand" href="#">Brand</a>
  </div>

  <!-- Collect the nav links, forms, and other content for toggling -->
  <div class="collapse navbar-collapse" id="bs-example-navbar-collapse-1">
    <ul class="nav navbar-nav">
      <li class="active"><a href="#">Link <span class="sr-only">(current)</span></a></li>
      <li><a href="#">Link</a></li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
        <ul class="dropdown-menu">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">Separated link</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">One more separated link</a></li>
        </ul>
      </li>
    </ul>
    <form class="navbar-form navbar-left">
      <div class="form-group">
        <input type="text" class="form-control" placeholder="Search">
      </div>
      <button type="submit" class="btn btn-default">Submit</button>
    </form>
    <ul class="nav navbar-nav navbar-right">
      <li><a href="#">Link</a></li>
      <li class="dropdown">
        <a href="#" class="dropdown-toggle" data-toggle="dropdown" role="button" aria-haspopup="true" aria-expanded="false">Dropdown <span class="caret"></span></a>
        <ul class="dropdown-menu">
          <li><a href="#">Action</a></li>
          <li><a href="#">Another action</a></li>
          <li><a href="#">Something else here</a></li>
          <li role="separator" class="divider"></li>
          <li><a href="#">Separated link</a></li>
        </ul>
      </li>
    </ul>
  </div><!-- /.navbar-collapse -->
</div><!-- /.container-fluid -->

请帮帮我！提前谢谢......

Answer 1

可能是因为SiteLayoutComponent和HomeComponent具有相同的路径i-e / home。
使用具有以下内容的一个组件

<layout-site-navbar></layout-site-navbar>
<h1>THIS IS THE HOME PAGE<h1>

或者如下所示定义您的路线

{ path: 'home', component: SiteLayoutComponent,
    children: [
      { path: '', redirectTo: 'detail', pathMatch: 'full' },
      { path: 'detail', component: HomeComponent}
    ]
  }

看看Defining Child Routes

Answer 2

让我们说您有一个要路由的父级，要显示一些信息，在此信息下，根据路由器配置，一次要显示两个组件。这就是我们可以做到的。空路径路由是关键。

`

{
    path: 'parent',
    component: ParentComponent,
    children: [
    {
        path: '',
        redirectTo: 'defaultChild',
        pathMatch: 'full'
    },
    {
        path: 'defaultChild',
        component: ChildComponent
    },
    {
        path: 'otherChild',
        component: OtherChildComponent
    }]
}

Angular默认子路由未加载父组件
