Having trouble moving to a different component in Angular?

In my application, I am facing an issue with navigating from List to Details component by passing the ID parameter. It seems that there is no response or error when attempting to call the relevant method. Below, you can find the code snippets related to the routing.module, list.component, and details.component:

routing.module

const routes: Routes = [
  {
    path: '',
    component: ListComponent,
    data: {...}
  },
  {
    path: '/details/:id',
    component: DetailsComponent,
    data: {...}
  }
];

list.component

constructor(private router: Router) {}

details(id) {
  // The code executes here and retrieves the id parameter correctly
  this.router.navigate(['/details'], {
    queryParams: { id: id }
  });
}

details.component

constructor(private route: ActivatedRoute) { }

ngOnInit(): void {
  this.route.paramMap
    .subscribe(params => {
      let id = +params.get('id');
    });
}

However, despite the correct implementation, the ngOnInit block of the details page does not seem to be triggered. Any insights on what might be going wrong with this setup?

Answer №1

When defining your route, make sure to use '/details/:id' where the ID is considered a Router Param, not a Query Param.

To navigate to this URL correctly, follow these steps:

ListComponent

this.router.navigate(['/details', id])

DetailsComponent

constructor(private route: ActivatedRoute) {}


ngOnInit() {
   const id = this.route.snapshot.params.id;      // Retrieve the ID from the current route "/details/:id"
}

You can also accomplish this using the following method:

ngOnInit() {
  this.route.params.subscribe(params => console.log(params.id))
}

For more detailed information, refer to the Angular Router Documentation

Answer №2

To successfully merge query parameters in your code, make sure to include queryParamsHandling: 'merge'

displayDetails(id) {
  // This section of the code captures and passes the id parameter correctly
  this.router.navigate(['/details'], {
  queryParams: { id: id },
  queryParamsHandling: 'merge'
  });
}
