[removed] not working in chrome

Question

This is the code which i used for window.onbeforeunload......

Answer 1

I'm running Chrome on MacOS High Sierra and have an Angular 6 project whithin I handle the window.beforeunload an window.onbeforeunload events. You can do that, it's worked for me :

handleUnload(event) {
  // Chrome
  event.returnValue = true;
}

It show me an error when I try to put a string in event.returnValue, it want a boolean.
