Question

我的RouteConfig定义了以下路径

@RouteConfig ([
    { path:'/main',name:'Home',redirectTo: ['Setup']},
    { path:'/setup',name:'Setup',component:SetupComponent},
    { path:'/configuration',name:'Configuration',component:ConfigurationComponent},
])

在模板中我有

    <ol>
        <li><a [routerLink]="['Setup']">Setup</a></li>
        <li><a [routerLink]="['Configuration']">Configuration</a></li>
        <li><a [routerLink]="['Home']">Home</a></li>                
    </ol>

在组件中，我尝试过的方法

this._Router.navigate(['Home']);

在这两种情况下，（使用routerLink指令和Router.navigate方法）尝试导航到“Home”路由时，我收到以下错误。

Component "AppComponent" has no route named "Home"

而具有与其关联的组件的路由都按预期工作。从Children路由器调用它们时的行为也一样。

如何路由/导航到名为“Home”的路线？

Answer 1

您无法为重定向路线指定名称。由于Home重定向到名为Setup的路由，因此我会使用Setup名称。

Answer 2

你应该使用/之前路由器名称this._Router.navigate（['/ Home']）;

Answer 3

在示例代码中，您具有家庭/主要路线对象：

您需要路由到路径-{ path:'/main', name:'Home', redirectTo: ['Setup'] },，而不是名称-/main。因此，您的html应该是：

Home

您的TypeScript应该是

<ol>
   <li><a [routerLink]="'/setup'">Setup</a></li>
   <li><a [routerLink]="'/configuration'">Configuration</a></li>
   <li><a [routerLink]="'/main'">Home</a></li>
</ol>

此外，我在route interface中没有看到this._Router.navigate(['/main']);属性，因此请考虑将其删除。

希望有帮助。
