sapui5 - Preventing router from navigating

Question

I need to prevent router to be navigated to another page (which is done by changing the hash) if some changes are made. Tried with HashChanger but it just fires 'hashChange' events with no way to prevent it from bubbling. The answer can be inside of JS-Signals library but it's unavailable directly for user-created SAP components.

Answer 1

There is a stop function on the router https://sapui5.hana.ondemand.com/#/api/sap.ui.core.routing.Router/methods/stop

if you call it, the router will stop listening to hashchanges.

There is also function isStopped(). To (re-)activate the router, call initialize(...).
