Angular: navigate to a different page dynamically without triggering a refresh of the current page

Within my EditUserComponent, I am utilizing a path parameter called id. If the id is invalid, I would like to redirect to either the home page or an error page without having to refresh the entire page. Is there a way to achieve this without updating the whole page? Currently, when I use the following code, it reloads on the home page.

constructor(private route: ActivatedRoute, private router: Router, private userService: UserService) {
    this.route.params.subscribe(params => this.id = params.id);
    if (!this.id || isNaN(this.id)) {
      this.router.navigate(['/home']);
    }
}

Answer №1

capture a snapshot of the route object

this.id = this.route.snapshot.params["id"]

ensure that your if condition is accurate, or consider an alternative approach:

this.route.params.subscribe(params => {
    this.id = params.id;
    if (!this.id || isNaN(this.id)) {
      this.router.navigate(['/home']);    
    }
});

Without seeing your router code, my guess is that you do not require a backslash in the redirect path.

this.router.navigate(['home']);

Utilize SetTimeOut Function


    constructor(private route: ActivatedRoute, private router: Router, private userService: UserService) {
      this.route.params.subscribe(params => this.id = params.id);
      if (!this.id || isNaN(this.id)) {
        setTimeout(() => { this.router.navigate(['/home']); }, 1000);
      }
