How to remove query param from URL. For example from www.expample.com/home?id=123&pos=sd&sd=iii make www.expample.com/home?id=123&sd=iii

EDIT: My version

this.activatedRoute.queryParams.subscribe(c => {
  const params = Object.assign({}, c);
  delete params.dapp;
  this.router.navigate([], { relativeTo: this.activatedRoute, queryParams: params });
}).unsubscribe();

Unfortunately, there is no clear-cut way to do this currently: https://github.com/angular/angular/issues/18011. However, as jasonaden commented on the linked thread,

This could be done manually by merging the old and new query params, removing the key you don't want.

Here is one way to do that:

Let's say you have your queryParams stored in some properties.

class MyComponent() {
  id: string;
  pos: string;
  sd: string;

  constructor(private route: ActivatedRoute, private router: Router) {}

  ngOnInit() {
    this.route.url.subscribe(next => {
      const paramMap = next.queryParamMap;
      this.id = paramMap.get('id');
      this.pos = paramMap.get('pos');
      this.sd = paramMap.get('sd');
    });
  }
}

A method to clear the pos parameter would look like this:

clearPosParam() {
  this.router.navigate(
    ['.'], 
    { relativeTo: this.route, queryParams: { id: this.id, sd: this.sd } }
  );
}

This will effectively navigate to the current route and clear your pos query parameter, keeping your other query parameters the same.

Angular2, how to clear URL query params on router navigate, WiseBird opened this issue on Jun 5, 2017 · 3 comments request here, instead see https://github.com/angular/angular/blob/master/CONTRIBUTING.md#​question QueryParamsHandling 'merge' does not remove query parameters #​18463.

You can remove a query parameter by using the merge option of queryParamsHandling and passing in null for any params you wish to remove.

// Remove query params
this.router.navigate([], {
  queryParams: {
    yourParamName: null,
    youCanRemoveMultiple: null,
  },
  queryParamsHandling: 'merge'
})

This option is simpler and requires less work to ensure you are not removing other params. You also do not need to worry about cleaning up an observable subscription when your component is destroyed.

Provide a way to remove specific parameter from query string #17202. In Angular 5 you can easily obtain and modify a copy of the urlTree by parsing the current url. This will include query params and fragments. let urlTree = this.router.parseUrl(this.router.url); urlTree.queryParams['newParamKey'] = 'newValue'; this.router.navigateByUrl(urlTree);

This is the best sulotion that i found, you can change url parameters

in constructor use

    private _ActivatedRoute: ActivatedRoute

then use this in init or in constructor body

    var snapshot = this._ActivatedRoute.snapshot;
    const params = { ...snapshot.queryParams };

  • This leaks an observable subscription. Router does not automatically cleanup the subscription to route.url.subscribe and must be manually tracked and disposed when the component is destroyed. Please consider my answer below which doesn't require any subscriptions and is simpler.
