Tips for Modifying the currentUrl identifier in Angular 2

I am trying to change the ID property of my currentUrl object within my component. My goal is for the ID to update and then fetch the corresponding data based on that ID. However, I keep encountering this error message:

"Cannot assign to read only property 'id' of object '[object Object]'"

Does anyone have any suggestions on how to resolve this issue?

addBranch(id){
      this.currentUrl = this.activatedRoute.snapshot.params;
      console.log(this.currentUrl.id); // Currently the id is undefined
      this.currentUrl.id = id; //Cannot assign to read only property 'id' of object '[object Object]'
      window.location.reload();
}

Answer №1

If you want to achieve this using the angular Router, start by injecting it into your Component:

constructor( private router: Router )
{}

(If you already have a constructor in place, make sure to extend it accordingly).

Now, you can simply utilize 

this.router.navigate(['/your-desired-route', id]);
instead of:

this.currentUrl.id = id;
window.location.reload();

This method will not trigger a complete page reload; rather, it will update the URL correctly and execute any necessary actions to process the route change (such as identifying the appropriate component to handle the request). This helps prevent unnecessary reinitialization of angular.
