interface UrlCreationOptions { relativeTo?: ActivatedRoute | null queryParams?: Params | null fragment?: string queryParamsHandling?: QueryParamsHandling | null preserveFragment?: boolean }
Property | Description |

relativeTo?: ActivatedRoute | null | Specifies a root URI to use for relative navigation. For example, consider the following route configuration where the parent route has two children. [{ path: 'parent', component: ParentComponent, children: [{ path: 'list', component: ListComponent },{ path: 'child', component: ChildComponent }] }] The following @Component({...}) class ChildComponent { constructor(private router: Router, private route: ActivatedRoute) {} go() { this.router.navigate(['../list'], { relativeTo: this.route }); } } A value of |
queryParams?: Params | null | Sets query parameters to the URL. // Navigate to /results?page=1 this.router.navigate(['/results'], { queryParams: { page: 1 } }); |
fragment?: string | Sets the hash fragment for the URL. // Navigate to /results#top this.router.navigate(['/results'], { fragment: 'top' }); |
queryParamsHandling?: QueryParamsHandling | null | How to handle query parameters in the router link for the next navigation. One of:
The "preserve" option discards any new query params: // from /view1?page=1 to/view2?page=1 this.router.navigate(['/view2'], { queryParams: { page: 2 }, queryParamsHandling: "preserve" }); The "merge" option appends new query params to the params from the current URL: // from /view1?page=1 to/view2?page=1&otherKey=2 this.router.navigate(['/view2'], { queryParams: { otherKey: 2 }, queryParamsHandling: "merge" }); In case of a key collision between current parameters and those in the |
preserveFragment?: boolean | When true, preserves the URL fragment for the next navigation // Preserve fragment from /results#top to /view#top this.router.navigate(['/view'], { preserveFragment: true }); |
