Angular router doesn't trigger onbeforeunload in IFrame

Question

I have an IFrame inside an angular route view. When I trigger a state change in the router via navigateByUrl the window.onbeforeunload function inside the IFrame ins't triggered. Same for addEventListern("beforunload",...).

First question: Why isn't it triggered?

Second: Is there a way to solve this easily?

Answer 1

Fixed it by using the onpagehide event.
