Angular's routing feature does not display the page for children

Exploring the world of routing in Angular 8 has been an interesting journey. Currently, I am faced with a challenge of creating a nested router that involves using children routes. Strangely, while the first route functions as expected, the second one seems to have issues where the URL changes correctly but the page does not update.

    const routes: Routes = [
      {
        path: "", 
        component: Component
      },
{
        path: "things", 
        component: Component1
      },
      {
        path: "partA/:id",
        component: Component2,
        children: [
          {
              path: 'partB/:id',
              component: Component3
          }]


        }
        ];

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

Within Component1.ts (which is functioning properly), the navigation code looks like this:

this.router.navigate(["partA" + item['name']], {state: {data: item}})

However, when it comes to Component2.ts:

 this.router.navigate(["partA/partB" + item['name']], {state: {data: item}})

The browser's URL reflects the correct path without any errors thrown, yet the page stubbornly remains on Component2 without updating. Even after including

<router-outlet></router-outlet>
in both Component1 and Component2, the issue persists.

Additional attempts with similar routing setups led to the same dilemma:

{
     path: "house/character/:id",
     component: InfoCharacterComponent
   },

Answer №1

When defining it as a child, the route URL should follow this structure: partA/:id/partB/:id. However, in your attempt, you are using

this.router.navigate(["partA/partB" + item['name']], {state: {data: item}})
, which results in partA/partB/:id that is non-existent.

To fix this issue, consider modifying the route or utilizing the correct format when calling navigate.

Answer №2

In the scenario where partA:id is present within partB, you have the option to utilize it as demonstrated below. This approach is compatible with your specified route.

this.router.navigate(["partA/" + partAid + "/partB" + item['name']], {state: {data: item}})
