How to detect fragment change?

Question

I need to identify when an anchor is changed and so call a function

Where I set the fragment:

  changeFragment(id) {
    this.router.navigate([], { fragment: id });
  }

Any help is welcome, thanks

Answer 1

Inject ActivatedRoute service in construtor, Then use fragement method in Activatedroute to listen fragement changes

Try this:

 this.route.fragment.subscribe( fragment =>{
      console.log(fragment);
 })
