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

问题

I am learning Angular.js and I am not able to figure out whats wrong with this simple code. It seems to look fine but giving me following error.

**Error**: Uncaught Error: [$injector:modulerr] http://errors.angularjs.org/1.3.14/$injector/modulerr?p0=app&p1=Error%3A%20…gleapis.com%2Fajax%2Flibs%2Fangularjs%2F1.3.14%2Fangular.min.js%3A17%3A381)

And before adding ng-app="app" (I was just keeping it as ng-app) it was giving me following errors. Why is that?

Error: [ng:areq] http://errors.angularjs.org/1.3.14/ng/areq?p0=Ctrl&p1=not%20a%20function%2C%20got%20undefined

回答1:

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:-

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

app.controller('myCtrl',function(){});
Call your javascript file in your html file

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

回答3:

You have to define your controller

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

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

回答4:

Be Sure that ng-app="app_name" define must match to

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

<html ng-app="myApp">
<body>
  <div ng-controller="Ctrl">
      <input ng-model="name">
      <h1>{{name}}</h1>
      <h2>{{age}}</h2>
  </div>
  <script>
    var app = angular.module('myApp',[]); // same to the above define appName
    app.controller('Ctrl',function($scope){
      $scope.age=24; // initialize age by injecting scope
    });
  </script>
</body>
<html>
