What I am trying to achieve is throwing a warning modal when the user tries to navigate from the create page without saving. Our application is using UI-Router. I am trying to use UI-Router's transition service to do this. I can stop the transition and it will continue or cancel it depending in the inner functions return value (true or false). My code so far:

ngOnInit() {
    //other code here
    const context = this;
    this.router.transitionService.onStart({}, function(transition) {
      context.openWarningDialog();
      // return boolean here
    });
  }

How can I return true or false in the function depending on which button the user presses on the modal?

Why aren't you using built-in routing ? The guard feature is literally made to handle this kind of behavior with `canDeactivate` – Aug 23 '18 at 07:07
It is a big project and I can't change the routing just for this feature. – Tamas Koos Aug 23 '18 at 07:12
May I suggest to change the title? It does not describe what you need to do – Massimo Costa Aug 23 '18 at 07:15

What kind of a modal are you using ? Is it ngx-bootstrap? – Senal Aug 23 '18 at 07:29
Yes, it is ngx-bootstrap. – Tamas Koos Aug 23 '18 at 07:36
