Angular 2 HostListener keypress detect escape key?

I am using the following method to detect keypresses on a page. My plan is to detect when the Escape key is pressed and run a method if so. For the moment I am just attempting to log which key is pressed. However the Escape key is never detected. 

@HostListener('document:keypress', ['$event'])
handleKeyboardEvent(event: KeyboardEvent) {
  console.log(event);
  let x = event.keyCode;
  if (x === 27) {
      console.log('Escape!');
  }
}
Solution

  • Try it with a keydown or keyup event to capture the Esc key. In essence, you can replace document:keypress with document:keydown.escape:

    @HostListener('document:keydown.escape', ['$event']) onKeydownHandler(event: KeyboardEvent) {
    console.log(event);
}
