Accessing $scope in AngularJS factory?

Question

I am new to AngularJS and find it very interesting, but I am a bit unclear about the following situation.

app.factory(\'deleteFac\', function($http){

var fa

Personally I would like to use scope from the factory, so, instead of moving all out I would pass the scope as parameter from the client which is calling to the factory.function().

Also I was having this same issue when trying to use $scope.watch(...) since we cannot use directly $scope from factories or services but I wanted to have this working in this way, so that is why I just updated my function to have scope as parameter and let the factory's client to send the $scope. So, this would be my solution:

var app = angular.module("myApp", []);

app.factory('MyFactory', function($http) {

      var factory = {};
      //This is only for my own issue I faced.
      factory.Images = {};

      factory.myFunction = function(id, scope) {
        //This is an example of how we would use scope inside a factory definition
        scope.details = "Initial Value";
        //In my case I was having this issue while using watch
        scope.$watch('details' , function(newValue, oldValue) {
          if(oldValue){
             scope.log = "Details was updated to : " +newValue;
            }
        });
        
        scope.details = "My Id is: "+id;
       };
        return factory;
});

//Controller: Factory's Client.
app.controller("MyController", ['$scope', 'MyFactory', function($scope, MyFactory) {
  
        MyFactory.myFunction(5, $scope);
}]);

  {{details}} 
  

  
{{log}} 

I hope this can help. Regards.
