AngularJS Error: Cannot access the property '$scope' as it is undefined

I encountered an issue with my angularJS code and I'm unsure of the cause. I attempted to utilize the $inject Property Annotation method as detailed in this guide

The error message "Uncaught TypeError: Cannot read property '$scope' of undefined on line 44" pops up, which corresponds to:

CarouselController.$inject['$scope'];

This is how my App.JS file looks like:

var bloxApp = angular.module('bloxApp', ['bloxApp.form', 'bloxApp.carousel']);
bloxApp.config(['$logProvider', function ($logProvider) {
$logProvider.debugEnabled(true);
}]);

In my blox-app.js, you will find the following structure (app.js loads first, followed immediately by blox-app.js):

    angular.module('bloxApp.common'[]);;angular.module('bloxApp').factory('lodash', ['$window', function (window) {
return window._;
}]);;(function () {
angular.module('bloxApp.form', []);
})();;(function () {
var FormController = function ($scope, $window, $http, _) {


    $scope.choices = [{ id: 'choice1' }, { id: 'choice2' }, { id: 'choice3' }];

    $scope.addNewPiece = function () {
        var newItemNo = $scope.choices.length + 1;
        $scope.choices.push({ 'id': 'choice' + newItemNo });
    };

    $scope.removePiece = function (int_id) {
        var newItemNo = $scope.choices.id;
        _.pull($scope.choices, _.find($scope.choices, { id: int_id }));
    };
}
FormController.$inject = ['$scope', '$window', '$http', 'lodash'];
angular.module('bloxApp.form')
    .controller('FormController', FormController);
})();
;;;(function () {
angular.module('bloxApp.carousel', []);
})();;(function () {
var CarouselController = function ($scope) {
    $scope.slides = [
          {
              image: 'http://lorempixel.com/400/200/', text: 'hello'
          },
          {
              image: 'http://lorempixel.com/400/200/food', text: 'hello'
          },
          {
              image: 'http://lorempixel.com/400/200/sports', text: 'hello'
          },
          {
              image: 'http://lorempixel.com/400/200/people', text: 'hello'
          }
    ];
}
CarouselController.$inject['$scope'];
angular.module('bloxApp.carousel')
    .controller('CarouselController', CarouselController);

})();

Answer №1

The correct syntax should be

CarouselController.$inject = ['$scope']
.

In your code, you forgot to include the = sign. This caused it to try accessing a property named $scope on the property of $inject within the CarouselController, instead of setting the $inject property to ['$scope'].
