Angular 2 router.navigate

Question

I'm trying to navigate to a route in Angular 2 with a mix of route and query parameters.

Here is an example route where the route is the last part of the path:

{ path: ':foo/:bar/:baz/page', component: AComponent }

Attempting to link using the array like so:

this.router.navigate(['foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

I'm not getting any errors and from what I can understand this should work.

The Angular 2 docs (at the moment) have the following as an example:

{ path: 'hero/:id', component: HeroDetailComponent }

['/hero', hero.id] // { 15 }

Can anyone see where I'm going wrong? I'm on router 3.

Answer 1

If the first segment doesn't start with / it is a relative route. router.navigate needs a relativeTo parameter for relative navigation

Either you make the route absolute:

this.router.navigate(['/foo-content', 'bar-contents', 'baz-content', 'page'], this.params.queryParams)

or you pass relativeTo

this.router.navigate(['../foo-content', 'bar-contents', 'baz-content', 'page'], {queryParams: this.params.queryParams, relativeTo: this.currentActivatedRoute})

Answer 2

import { ActivatedRoute } from '@angular/router';

export class ClassName {
  
  private router = ActivatedRoute;

    constructor(r: ActivatedRoute) {
        this.router =r;
    }

onSuccess() {
     this.router.navigate(['/user_invitation'],
         {queryParams: {email: loginEmail, code: userCode}});
}

}


Get this values:
---------------

ngOnInit() {
    this.route
        .queryParams
        .subscribe(params => {
            let code = params['code'];
            let userEmail = params['email'];
        });
}
