What is the best way to access a variable from a different JavaScript file?

How can I access the 'name' value from a JavaScript file in an AngularJS application?

Consider the following code snippet:

var myApp = angular.module('myApp',[]);
myApp.factory('UserService', function() {
    return {
        name : 'blabla'
    };
});

function MyCtrl($scope, UserService) {
    $scope.name = UserService.name;
};

Answer №1

AngularService is a specialized service in Angular framework, and it must be injected to be utilized within the desired component such as a directive, another service, or a controller. It cannot be accessed outside of the Angular environment.

Below is an example of how one can access this service within a sample directive:

// Include myApp module as a dependency
angular.module('sampleModule',['myApp'])
   // Inject AngularService here
   .directive('sampleDirective',['AngularService',function(AngularService){
        return {
             scope:{},
             restrict:'E',
             link:function(scope, elem, attr){
                   // Access AngularService here
                    console.log(AngularService.name);
             }
      }

}])
.

Could you clarify what you mean by a different JavaScript file? In order to access the value of "name" stored in "UserService" from another part of your application, such as another controller or directive, you will need to inject that service ("UserService").
