angular - Angular2, how to clear URL query params on router navigate

Question

I am struggling with clearing out URL params during nav in Angular 2.4.2. I have tried attaching every option to clear the params in the below navigation line, or any mix therein with navigate, or navigateByUrl, but cannot figure out how to accomplish.

this.router.navigateByUrl(this.router.url, { queryParams: {}, preserveQueryParams: false });

As an example I am at route /section1/page1?key1=abc&key2=def and want to stay at the same route but remove all the url parameters, so the end result should be /section/page1

Answer 1

As DeborahK pointed out, when I was navigating to this.router.url, that URL already had the url params embedded. To solve I stripped the params off the URL as a string, and then used navigateByUrl to jump there.

let url: string = this.router.url.substring(0, this.router.url.indexOf("?"));
this.router.navigateByUrl(url);
