This type of decorator works with services and factories. I expected it to work with providers as well. I've tried the following to decorate ui-router's $stateProvider:
app.config(function($provide) {
$provide.decorator('$state', function ($delegate) {
return $delegate;
});
});
Here's a demo plunk
It should work just the same? See plunk # http://plnkr.co/edit/rSFo1xCoRHjWmrSjJBN1
var app = angular.module('plunker', []);
app.provider('provider', function () {
this.$get = function () {
var provider = {};
var value = 'test';
provider.get = function() {
return value;
}
provider.set = function(param) {
value = param;
}
return provider;
}
});
app.config(function($provide) {
$provide.decorator('provider', function ($delegate) {
$delegate.set('delegate');
return $delegate;
});
});
app.controller('MainCtrl', function($scope, provider) {
$scope.name = provider.get();
});

/*service */
app.service('sharedProperties', function () {
var property = 'First';
return {
getProperty: function () {
return property;
},
setProperty: function(value) {
property = value;
}
};
});
/*first contoller */
app.controller('loginCtrl',function($scope,$location,$http,$window,sharedProperties){
$scope.submit =function(){
var username=$scope.username;
var pass=$scope.password;
sharedProperties.setProperty(username);
$location.path('/userdashboard');
$window.location.reload();
});
}
});
/*second controller*/
app.controller('empController', function($route,$scope,$http,$routeParams,sharedProperties){
$scope.getEmployees = function(){
alert( sharedProperties.getProperty());
};
};
Try this, it will work for you. :
<div ng-app="myApp" ng-controller="myCtrl">
<button ng-click="sendData();"></button>
</div>
<script>
var app = angular.module('myApp', []);
app.controller('myCtrl', function($scope, $http) {
function sendData($scope) {
var arrayData = [1,2,3];
$scope.$emit('someEvent', arrayData);
}
});
app.controller('yourCtrl', function($scope, $http) {
$scope.$on('someEvent', function(event, data) {
console.log(data);
});
});
</script>
Service does not need to return anything. You have to assign everything in this variable. Because service will create instance by default and use that as a base object.
app.service('sharedProperties', function () {
this.property = 'First';
});
Then in controller
sharedProperties.property = $scope.username;
Had you been looking to use factory
app.factory('sharedProperties', function () {
var factory = {};
factory.property = 'Hello';
factory.setProperty = function (value) {
factory.property = value;
};
return factory;
});
Then in controller you would use it
sharedProperties.setProperty($scope.username); // Setter
$scope.var = sharedProperties.property; //getter
EDIT
Working Plnkr
You can assign members to $rootScope, which will store data globally for your app. Just inject $rootScope to each controller.
For instance...
/*first controller */
app.controller('loginCtrl',function($scope,$rootScope,$location,$http,$window,sharedProperties){
$scope.submit =function(){
var username=$scope.username;
var pass=$scope.password;
$rootScope.username = username;
$location.path('/userdashboard');
$window.location.reload();
});
}
});
This will make 'username' available to any controller that injects and consumes $rootScope.
/*second controller*/
app.controller('empController', function($route,$scope,$rootScope,$http,$routeParams,sharedProperties){
$scope.getEmployees = function(){
alert($rootScope.username);
};
};
I have a module with a service defined:
var ngError = angular.module('ngError', []);
ngError.service('ErrorService', ['$scope', function($scope) {
$scope.displayErrors = function(errors) {
alert(errors);
}
}]);
Then I have another module:
var ngLogin = angular.module('ngLogin', ['ngError']);
Which has a controller that attempts to use the first service defined on ngError:
ngLogin.controller('LoginCtrl', ['$scope', 'LoginService', 'ErrorService', function($scope, LoginService, ErrorService) {
$scope.user = {};
$scope.user.id = 0;
$scope.user.token = '';
$scope.login = function(callback) {
LoginService.login($scope.user.username, $scope.user.password, function(token) {
$scope.setToken(token);
$scope.$apply();
if (typeof callback === 'function') {
callback(callback);
}
}, function(errors) {
ErrorService.displayErrors(errors);
});
};
}]);
But some reason this is throwing the following error:
Unknown provider: $scopeProvider <- $scope <- ErrorService
You cannot use $scope within a service. Change the service as follows and it will work:
var ngError = angular.module('ngError', []);
ngError.service('ErrorService', [function() {
this.displayErrors = function(errors) {
alert(errors);
}
}]);
Try like this , working best for me
var app = angular.module('MyApp', []);
app.service('MyService', function () {
var property = 'First';
this.myFunc = function (x) {
return x*5;
}
});
//
controller 2 under second app module
var app = angular.module('AnotherApp',[]);
app.controller("AnotherAppCtrl", function($scope,MyService) {
$scope.value = MyService.myFunc(4);
});
I'm trying to write a unit test using karma and jasmine for an Angular controller that depends on a service
storesController.js
(function () {
var app = angular.module('storesController', ['storesService']);
app.controller('StoresListController', function ($scope, StoresService) {
$scope.getStores = function () {
StoresService.getStores().then(function (data) {
$scope.stores = data.data;
});
};
$scope.getStores();
$scope.deleteStore = function (id) {
StoresService.deleteStore(id).then(function () {
$scope.getStores();
});
};
});
storesService.js
(function () {
var app = angular.module('storesService', []);
app.factory('StoresService', ['$http', function ($http) {
var stores = [];
stores.getStores = function () {
return $http.get(/api/getStores');
};
stores.deleteStore = function (storeID) {
return $http.delete(/api/deleteStore/'+storeID);
};
return stores;
}]);
})();
And the test,
controllers.spec.js
describe('StoresController', function () {
beforeEach(module('storesController'));
var scope;
var storesServiceMock;
var controller;
beforeEach(inject(function ($controller, $rootScope) {
storesServiceMock = {
getStores: function() {
},
deleteStores: function() {
}
};
spyOn(storesServiceMock, 'getStores').and.returnValue({name : 'TestName', country : 'TestCountry'})
scope = $rootScope.$new();
controller = $controller('StoresListController', {
$scope: scope, StoresService: storesServiceMock
});
}));
it('scope.stores should be defined', function () {
expect(scope.stores).toBeDefined;
});
});
And I'm getting
TypeError: StoresService.getStores(...).then is not a function at n.$scope.getStores
I've also tried width httpBackend but I'm not be able to make it work, any clue about what I'm doing wrong?
Have the spy return a promise.
With ES2015:
spyOn(storesServiceMock, 'getStores').and.returnValue(Promise.resolve({name : 'TestName', country : 'TestCountry'}));
With $q:
spyOn(storesServiceMock, 'getStores').and.callFake(function() {
var deferred = $q.defer();
deferred.resolve({name : 'TestName', country : 'TestCountry'}));
return deferred.promise;
});
I am writing a Factory/Service for the first time and trying to get an image from a factory into controller but getting undefined when in the factory function for some reason.
Here is the fiddle
https://jsfiddle.net/vijay_vadlamani/2qL2Lh5r/1/
Html:-
JS:-
angular.module('myApp').factory('imageFactory', function() {
return function contentImage($scope) {
$scope.getImage = function(content) {
return getContentImage(content);
};
};
});
angular.module(myApp).controller('getImageCtrl', ['$scope', 'imageFactory', function($scope, imageFactory) {
$scope.getListImage = function(content) {
return imageFactory.getImage(content);
};
}]);
Try to declare service like this:
var app = angular.module('myApp',[]);
app.factory('imageFactory', function()
{
var service =
{
getImage: function(content)
{
return getContentImage(content);
}
};
return service
});
and use it like this:
app.controller('getImageCtrl', ['$scope','imageFactory',function($scope, imageFactory)
{
$scope.getListImage = function(content)
{
return imageFactory.getImage(content);
};
}]);
Here's demo
So I created with angular a small factory to get my local json file now I wanna pass that data to my controller but it can't find the factory name and says 'unresolved variable'.
Here is the snippet of my code what I guess is relevant for now.
(function () {
var app = angular.module('locatieTool', ['ngRoute']);
app.controller('teamController', function ($scope) {
function init () {
dataFactory.getTeams().success(function(data) {
$scope.teams = data
});
}
init();
console.log($scope.teams);
});
// factory
app.factory('dataFactory', function($http) {
var team = {};
//get local data
team.getTeams = function() {
return $http.get ('http://localhost:4040/');
};
return team;
});
})();
My goal is just to console log the $scope.teams, than I can do more with the data.
you should include "dataFactory" inside your controller
(function () {
var app = angular.module('locatieTool', ['ngRoute']);
app.controller('teamController', function ($scope, dataFactory) {
function init () {
dataFactory.getTeams().success(function(data) {
$scope.teams = data
});
}
init();
console.log($scope.teams);
});
// factory
app.factory('dataFactory', function($http) {
var team = {};
//get local data
team.getTeams = function() {
return $http.get ('http://localhost:4040/');
};
return team;
}); })();
I believe you need to pass your factory into the controller:
app.controller('teamController', function ($scope, dataFactory) {
function init () {
dataFactory.getTeams().success(function(data) {
$scope.teams = data
});
}
init();
console.log($scope.teams);
});
