AngularJS - Run function of child controller from parent controller

Question

I have read many questions on this but still can\'t find solution that will be clean and reusable enough.

What I tried and don\'t want to use:

• Events - $em

Answer 1

One approach is to use the new ngRef directive:

Then use it in the controller:

function startFirstTimer() {
    /* How to run start() function of TimerController here? */
    ctrl.timerOne.start();
}

The ngRef directive was introduced as a new feature with AngularJS V1.7.1.

For more information, see AngularJS ng-ref Directive API Reference.
