This is a general dependency injection question. Obviously I am doing it wrong.
I am trying to get angular-xeditable working in my app.
https://vitalets.github.io/angular-xeditable/
I've installed it using bower, and added the appropriate script link to my head.
Now I'm trying to inject it.
The docs say
var app = angular.module("app", ["xeditable"]);
so, in my app: I do this:
portalApp.controller('portalController',
['$scope', '$http','$filter', 'xeditable',
function($scope, $http, $filter, xeditable) {
but I get the provide error, meaning it can't find xeditable.
angular.js:13642Error: [$injector:unpr] http://errors.angularjs.org/1.5.6/$injector/unpr?p0=xeditableProvider%20%3C-%20xeditable%20%3C-%20portalController
What am I doing wrong?
OK, duh. It should be
var portalApp = angular.module("portalApp", ['xeditable']);
portalApp.controller('portalController', ['$scope', '$http','$filter', function($scope, $http, $filter) {
I'm still getting lots of errors, but at least not that one.

got to work with angular JS on learning how angular works.
I am trying controllers, directvies and services in an example project:
[http://codepen.io/anon/pen/PpOERy][1]
Actually I got this error if I try to use my service on clicking the button:
TypeError: Cannot read property '*****' of undefined
Whats my failure?
Regards n00n
You forgot to annotate your service, little typo ;)
Your code
myApp.controller('MainCtrl', ['$scope', function ($scope, CalculatorService) {
Correct code
myApp.controller('MainCtrl', ['$scope', 'CalculatorService', function ($scope, CalculatorService) {
I have been struggling to find a solution for this problem:
I am using Angular.js on my site.
I use CoffeeScript to write my JavaScript in Visual Studios 2012. When I save my CoffeeScript - both a minified and un-minified version of the JavaScript file is saved.
While using any minified version of JavaScript files on my webpage I keep getting this error:
Error: $injector:unpr
Unknown Provider
Unknown provider: nProvider <- n
This error results from the $injector being unable to resolve a required dependency. To fix this, make sure the dependency is defined and spelled correctly. For example:
If I don’t use the minified version everything works fine.
Here is how I use angular to declare my App in each JavaScript file
(function() {
var myApp;
myApp = angular.module("myApp", ['uploaddirective']);
myApp.controller("videoController", function($scope, $http, $compile) {
Can anyone help me to resolve this issue?
Use array notation for minification-safe dependency injection:
myApp.controller("videoController", ['$scope', '$http', '$compile', function($scope, $http, $compile) {
Another option is to use build task to automatically annotate injections for you:
// #ngInject
myApp.controller("videoController", function($scope, $http, $compile) {
You will need grunt or gulp plugin for this, like ngAnnotate.
https://docs.angularjs.org/guide/di
When you minifying the above code you will get something like
a.controller("videoController", function(x, y, z) {...
note that $scope, $http, $compile are replaced with x, y, z.
So when angular starts to execute Controller can't find the injectors because $scope, $http, $compile are replaced with x, y, z and there are no inject-able providers as x, y or z, so angular will trigger a error saying Unknown Provider.
solution 1
you can follow Inline Array Annotation as,
myApp.controller("videoController", ['$scope', '$http', '$compile', function($scope, $http, $compile) {...
after minifying this you will get something like
a.controller("videoController", ['$scope', '$http', '$compile', function(x, y, z) {...
minifying process doesn't effect on strings, here angular will use a array with strings that will match the providers. Here angular will match the x with $scope and so on.
solution 2
$inject Property Annotation
var MyController = function($scope, $http, $compile) {
// controller function ...
}
MyController.$inject = ['$scope', '$http', '$compile'];
myApp.controller("videoController", MyController);
additionally check ng-annotate
I am trying to include ngCookies in a project. The angular cookies library is included in my index.html after the ionic.bundle.
I can see on the network tab of the developer tools that it is actually loading. Angular doesn't show any error when loading the page, as it usually does when a module is missing. The problem is that, when in my code I try to access the functions of the $cookies service, the $cookies variable is actually pointing to an empty object.
Here are some relevant code snippets:
On the definition of my app.js
angular.module('myApp', [
'ionic',
'ngCookies',
'ngMessages',
'rt.eventemitter',
'myApp.views']);
On my factory:
angular.module('myApp.views')
.factory('UserStore', ['$rootScope', '$q', '$cookies', '$timeout',
function($rootScope, $q, $cookies, $timeout){
var user = {};
function setSessionId(sessionId){
console.log(">> setting sessionId to:",sessionId);
user.sessionId = sessionId;
$cookies.put('sessionId', user.sessionId);
}
return{ setSessionId:setSessionId}
}
]);
In this case, when I try to call the setSessionId method I get an error that $cookies.put is not a function since, as I mentioned above, $cookies is just an empty object.
Any Ideas?
it depends on which angular version you use!
they changed a lot in angular 1.4.. in angular 1.3 when you set a cookie you can just assign it:
$cookies.sessionId = user.sessionId;
I'm trying to use cookies ( set and retrieve), I have this code copies from a site and changed it, but I wouldn't work and all my angular parts stop working.
This is a sample of angular website
can you tell me where the problem is?
var app = angular.module('test', ['ui.bootstrap'], ['ngCookies']);
app.controller('ExampleController', ['$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, $cookieStore) {
...
}]);
Your syntax is incorrect, go through the docs to find the correct syntax for angular.
I'm having an issue with angular minification when I release. I've redone my controller to have annotations as recommended, but still get the same error:
Error: Unknown provider: nProvider <- n
Here's my first few lines of code for the controller:
var app = angular.module('myApp', ['ngGrid', 'ui.bootstrap.dialog']);
app.controller('MyCtrl', ['$scope', '$dialog', '$http', function ($scope, $dialog, $http){
UPDATE: sorry, I found that there was another function I was using which was taking in $scope as parameter. That was causing the issue. I basically did the same thing to annotate its parameters, and now it works.
