I'm trying to inject my factory into my controller and I'm getting this error from AngularJS:
Error: $injector:unpr Unknown Provider
I have looked through almost all of the questions on here and still cannot find a solution to my problem. I believe my controller and factory and declared correctly and the injection is correct but it looks like this isn't the case.
My factory code is as follows:
var app = angular.module('test', []);
app.factory('processingFactory', function () {
var factory = {};
factory.newTest = function() {
console.log("TEST");
}
return factory;
});
This is then injected into the controller which looks like this:
angular.module("test", ["angularModalService", "anguFixedHeaderTable",
'angular-loading-bar', "ngResource", "agGrid",
'ui.tree']).controller("dashboardController", [
"$scope",
"$timeout",
"$http",
"$window",
"$interval",
"$resource",
"ModalService",
"$filter",
'$q',
'processingFactory',
function($scope, $timeout, $http, $window, $interval, $resource,
ModalService, $filter, $q, processingFactory) {
//other code removed
$scope.newWorkorder = processingFactory.newWorkorder;
}
]);
This function is called through a button click on the web page. All of the files needed are in script tags on this html page. I am fairly new to angular so this could be a simple error or something I am not aware of.
Calling angular.module with an array as the second argument declares a module, which can only happen for any given module name. You are declaring the module twice (once in your controller code, and again in your factory code).
Try changing the first part of your factory code to:
var app = angular.module('test');
If you are doing the same thing elsewhere in the app you will need to remove the second argument there too, so that there is only one module declaration in the whole app.
if there are any dependencies for your module "test" why do not you have them declared in the first line itself like:
var app = angular.module("test", ["angularModalService", "anguFixedHeaderTable",
'angular-loading-bar', "ngResource", "agGrid",
'ui.tree']);
Then declare your controller like::
app.controler(...)
Things should work fine.

I have the following preloader.js factory file included in my project.
angular.module('movieSeat')
.factory('preloader', function( $q, $rootScope ) {
In my controller I inject the factory as following:
angular.module('movieSeat')
.controller('moviesearchCtrl', ['$scope', 'moviesearchFactory', function ($scope, moviesearchFactory, preloader) {
When I try to use the preloadImages function inside the preload controller:
$scope.imageLocations = [
"https://image.tmdb.org/t/p/w300_and_h450_bestv2//nlqFgG7jfBITl8fJHzL72jXwYLt.jpg",
"https://image.tmdb.org/t/p/w300_and_h450_bestv2//ghL4ub6vwbYShlqCFHpoIRwx2sm.jpg",
"https://image.tmdb.org/t/p/w300_and_h450_bestv2//weUSwMdQIa3NaXVzwUoIIcAi85d.jpg",
];
preloader.preloadImages($scope.imageLocations)
I get the following error:
Cannot read property 'preloadImages' of undefined
If I comment out the preloader.preloadImages($scope.imageLocations) code the error is gone. So to me it looks like injecting the preloader factory in my controller works fine but I can't figure out why I can't call the function preloadImages on the preload factory.
There's a typo in the dependency injection list. You forgot to add preloader in the list of dependency strings.
.controller('moviesearchCtrl', ['$scope', 'moviesearchFactory', 'preloader' /*here*/, function ($scope, moviesearchFactory, preloader) {
You need to reference your factory/service 'preloader' in your controller call as follows:
angular.module('movieSeat')
.controller('moviesearchCtrl', ['$scope', 'moviesearchFactory', 'preloader', function ($scope, moviesearchFactory, preloader) {
})
i have an angularjs factory to which i am injecting underscore and application is working fine but when i try to write jasmine test cases on it i am getting an error underscore provider is not found
i have my factory like
angular.module("sample")
.factory("example", example);
example.$inject = ["$document", "$compile", "$rootScope", "$timeout", "$q", "underscore"];
function example($document, $compile, $rootScope, $timeout, $q, _) {
}
and i have my module defined as
(function(){
angular.module(samlple,[]);
})();
and my test case is as
beforeEach(module('sample'));
beforeEach(module('ionic'));
beforeEach(inject(function ($document, $compile, $rootScope, $timeout,underscore,example) {
}
its giving error
Error: [$injector:unpr] Unknown provider: underscoreProvider <- underscore
Add import underscore in your index.html, then add it as a service.
var underscore = angular.module('underscore', []);
underscore.factory('_', function() {
return window._; // assumes underscore has already been loaded on the page
});
And
//Now we can inject underscoreJS in the controllers
function MainCtrl($scope, _) {
//using underscoreJS method
_.max([1,2,3,4]); //It will return 4, which is the maximum value in the array
}
But I recommend you to use lodash! It has more cool functions. Information about how to use lodash with Angular you can find here .
Piggybacking on #Bakhtier's answer, I used the following to get Karma/Jasmine to recognize lodash so I could use it in my services, as well as the rest of my app.
angular.module('app', ['app.services', 'lodash']);
angular.module('app.services', ['lodash']).factory('MyService', ['_', function (_){
// your code bits
}]);
angular.module('lodash', []).factory('_', function() {
return window._;
});
Hope that helps someone out.
I don't know why I am getting this error.
The error I am getting is Error: [ng:areq] Argument 'PreviewController' is not a function, got undefined.
Can someone help me out with this?
Also is there any other way to inject services in a controller?
My code is as follows:
(function() {
'use strict';
angular
.module('MyModule')
.controller('PreviewController' ['$scope','Service1','Service2',
function($scope, $http) {
$http.get("https://api.myjson.com/bins/30e2a")
.success(function(response) {
//Dummy data taken from JSON file
$scope.firstName = response.firstName;
$scope.lastName = response.lastName;
$scope.dateAdded = response.dateAdded;
});
//Functions have been defined. Functionality to be added.
$scope.cancelAndBack = function() {
window.history.back();
};
}]);
}());
You are defining you module incorrectly.
`angular.module('MyModule')`
Is looking for an already initialised module called 'MyModule'.
If you are creating a module from scratch you need to empty array. This would be more module dependencies.
`angular.module('MyModule', [])`
This is how angular knows the difference between, 'create an app' and 'get me an app'.
Finally services. Your using angulars array notation. That is so you can minify your javascript.
angularjs injection system works by name, that's how it can find the dependencies your require, that's also why you can list them in any order you like. However minifying your code changes your variable names and so breaks angular's injection.
The solution is to provide an array of strings telling angular the services you wish to inject and the order they are injected in.
So your array values and properties passed into your controller function must match.
Correct:
.controller('test', ["$scope", "$http", "myService", function( $scope, $http, myService){}]);
Incorrect: (myService won't be defined as its missing from the array)
.controller('test', ["$scope", "$http", function( $scope, $http, myService){}]);
I'm new to angular and have the following code.
angular.module('MyApp')
.controller('loginController', ['$scope', '$http', 'conditionalDependency',
function ($scope, $http, conditionalDependency{
}
I would like to have conditionalDependency loaded conditionally. Something like this
if(true)
{
//add conditionalDependency
}
How can this be done. I've seen this post . However, my requirement is that I have the dependency specified in function
Thanks in advance.
Not quite clear as to why you would have to have it in a named function like in your example but...
If you need conditional dependencies, I would suggest taking a look at the following:
Conditional injection of a service in AngularJS
I've used this method in a couple niche scenarios and it works quite well.
EXAMPLE:
angular.module('myApp').controller('loginController',
['$injector', '$scope', '$http',
function($injector, $scope, $http) {
var service;
if (something) {
service = $injector.get('myService');
}
});
You can use it even without injecting injector in your controller
if(something){
var injector = angular.element(document).injector();
var myService = injector.get('myService')
}
Use:
angular.injector().get('conditionalDep');
You can inject $injector once to your file and call $injector.get('dep');
I'm trying to use cookies ( set and retrieve), I have this code copies from a site and changed it, but I wouldn't work and all my angular parts stop working.
This is a sample of angular website
can you tell me where the problem is?
var app = angular.module('test', ['ui.bootstrap'], ['ngCookies']);
app.controller('ExampleController', ['$cookieStore', function ($scope, $cookieStore) {
// Put cookie
$cookieStore.put('myFavorite', 'oatmeal');
// Get cookie
$scope.itemValue = $cookieStore.get('myFavorite');
// Removing a cookie
//$cookieStore.remove('myFavorite');
}]);
and usage is :
<span ng-controller="ExampleController">{{itemValue}}</span>
it gives me this error
Error: [$injector:modulerr] http://errors.angularjs.org/1.3.0-beta.5/$injector/modulerr?......
You're declaring your module wrong, the second parameter should be an array of dependencies, but you're passing each dependency as it's own separate array. It should be:
var app = angular.module('test', ['ui.bootstrap', 'ngCookies']);
You're using a "minification safe" array for your controller, but you're only including $cookieStore, not $scope, it should be:
app.controller('ExampleController', ['$scope', '$cookieStore', function ($scope, $cookieStore) {
...
}]);
Your syntax is incorrect, go through the docs to find the correct syntax for angular.
