Angular 2投掷错误:出口未激活 [英] Angular 2 throwing error: Outlet is not activated
问题描述
我已经设置了我的应用程序,以便我有一个Recipe Book
,其中有一个Recipies
列表,当我单击配方"时,它会在嵌套路径中显示Recipe Details
.然后,它还有一个按钮,单击该按钮可在Recipes Details
内的嵌套路径中加载配料.
I have set up my app so that I have a Recipe Book
which has a list of Recipies
which when I click on a Recipe it then shows the Recipe Details
in a nested route. This then also has a button that when clicked loads the ingredients in a nested route inside the Recipes Details
.
到目前为止,除了我尝试导航到另一个Recipe
之外,路由似乎都可以工作.如果Ingredients
托盘(路线)处于活动状态,则它将更改配方并折叠Ingredients
路线,如果然后尝试导航(未打开配料),则会出现以下错误:
So far the routing seems to work, except when I try to navigate to another Recipe
. If the Ingredients
tray(route) is active then it will change Recipe and collapse the Ingredients
Route, If I then try and navigate (without opening the Ingredients) I get the following error:
Uncaught (in promise): Error: Outlet is not activated
Error: Outlet is not activated
好像我的路由器需要Ingredients
才能处于活动状态,否则它无法理解嵌套的路由.那就是我的看法,但不确定如何解决或何时出错.
It looks like I the router needs Ingredients
to be active or else it doesn't understand the nested route. Thats my take on it but not sure how to fix it or when I went wrong.
single-recipe-book-page.component.html
<app-tray class="recipe-list">
<app-recipe-list [recipe]="recipe"></app-recipe-list>
</app-tray>
<router-outlet></router-outlet>
recipe-detail.component.html
<app-tray class="recipe">
The routing has worked and loaded recipe.
</app-tray>
<router-outlet></router-outlet>
ingredients-list.component.html
<app-tray class="ingredients-list">
Recipe Ingredients have loaded.
</app-tray>
app.routes.ts (已更新)
export const routerConfig : Route[] = [
{
path: 'recipe-books',
children: [
{
path: ':id', component: SingleRecipeBookPageComponent,
children: [
{
path: 'recipes',
children: [
{ path: ':id', component: RecipeDetailComponent,
children: [
{ path: '', component: IngredientsListComponent },
{ path: 'ingredients', component: IngredientsListComponent }
]
},
{ path: 'new', component: IngredientsListComponent },
{ path: '', component: RecipeDetailComponent }
]
},
{ path: '', redirectTo: 'recipes', pathMatch: 'full' }
]
},
{ path: '', component: RecipeBooksPageComponent }
]
},
{ path: 'ingredients', component: IngredientsComponent },
{ path: '', redirectTo: 'recipe-books', pathMatch: 'full' },
{ path: '**', redirectTo: 'recipe-books', pathMatch: 'full' }
];
推荐答案
此路由无效,您应该为此报错.
This route is invalid and you should get an error for it.
{ path: '' },
一条路线需要具有component
,redirectTo
或children
.
A route either needs to have a component
, a redirectTo
, or children
.
如果空路径路线中没有子路线,那么它也应该具有pathMatch: 'full'
.
If an empty path route has no children it also should have pathMatch: 'full'
.
我想你想要的是
{ path: '', component: DummyComponent, pathMatch: 'full' },
其中DummyComponent
是具有空视图的组件.
您可以为所有这些路径重复使用相同的DummyComponent
.
Where DummyComponent
is a component with an empty view.
You can reuse the same DummyComponent
for all these paths.
