What is the best way to invoke a function inside a directive using an external controller?

After researching online, it appears that there are numerous questions similar to mine but unfortunately, none of the solutions provided worked for me.

In my current situation, I have a directive which includes a function like this (within the directive):

link: function(scope, element, attrs) {

     scope.myfunction = function (){
          console.log('function run');
     };
}

I want to be able to call this function from a controller using a simple command like this:

$scope.myFunction();

This way, I can easily access and execute the function from a part of my page outside of the directive code, perhaps by adding a button like this:

<button ng-click="myFunction()">Run</button>

My question is, is it possible to achieve this functionality?

Answer №1

After much trial and error, I was able to solve the issue by utilizing scope broadcasting in the following manner.

Within the controller:

$scope.beginProcess = function(){
    $scope.$broadcast('startprocess');
};

Inside the directive:

scope.$on('startprocess', function () {
     console.log('process initiated');
});
