Angularjs Uncaught Error: [$injector:modulerr] when migrating to V1.3

After AngularJS version 1.3 global controller function declaration is disabled

You need to first create an AngularJS module & then attach all the components to that specific module.

CODE

function Ctrl($scope) {
    $scope.age = 24;
}

angular.module('app', [])
    .controller('Ctrl', ['$scope', Ctrl]);

Specifically for your case, there is some issue with AngularJS 1.3.14 (downgrade it to 1.3.13 works fine). Though I'd prefer you to use angular 1.2.27 AngularJS 1.6.X, Which is more stable version & latest release of AngularJS.

Working Plunkr

UPDATE:

You could do your current code to working state by allow global controller declaration inside angular.config. But this isn't the correct way to run angular application.

function Ctrl($scope) {
    $scope.age = 24;
}

angular.module('app', [])
    .config(['$controllerProvider',
        function ($controllerProvider) {
            $controllerProvider.allowGlobals();
        }
    ]);

I was myself stuck in this issue for sometime. Check for following in order:-

  1. The path to you angular.js script is correct (whether you are calling it in your HTML from a local source or as an external resource).

  2. Next, once your angular.js is correct check if your app is initialized or not.

    var app=angular.module('app',[])//in your app.js file

    <body ng-app="app">//in your html

  3. Next register your controller with the app and pass in all necessary injections

    app.controller('myCtrl',function(){});

  4. Call your javascript file in your html file

    <script src="app.js"></script>


You have to define your controller

var app = angular.module('app', []);

app.controller('Ctrl', ['$scope',function($scope) {
  $scope.age = 24;
}]);
