How to access a variable in an Angular Factory's callback function from outside the factory

Here's a look at the structure of My Factory:

.factory('MyFactory', function(){
    return: {
         someFunction: functon(firstParam, secondParam, resultObject) {
                     $http.get(url).success(resultObject);
        }     
    }
})

And this is how my controller is set up:

.controller('MyCtrl', function($scope) {
    MyFactory.someFunction(paramOne, paramTwo, function(resultObj) {
          $scope.result = resultObj;
          console.log($scope.result) //contains the object
     });
    console.log($scope.result) //currently returns undefined
}):

I want $scope.result to be accessible throughout the controller and not just within the callback. As it stands, it can only be accessed within the callback function.

I've identified that the issue lies in the variable scope being limited to the callback function, but I'm unsure on how to resolve this effectively.

Answer №1

The issue lies not in the scope of the variable within the callback function, but rather in accessing $scope.result outside the function before the completion of the $http request, resulting in it being undefined.

To resolve this, ensure that the $http request finishes before the controller loads by utilizing the resolve function in the routes. By firing off the request and waiting for its completion before loading the route, you can directly inject the result into the controller.
