My "Hello world" Angular Program is not working in 1.3.14 version

I am new in angularjs. i have created a helloworld program. for angular reference i used CDN. but the problem is the program is working on version 1.0.8 version but not working in 1.3.14 version. I can not say what is the problem. My code is given bellow:

<!DOCTYPE html>
<html ng-app>
<head>
    <meta charset="utf-8"/>
</head>
<body>
<header>
    <h1 ng-controller="HelloWorldCtrl">{{helloMessage}}</h1>
</header>

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<!--<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>-->
<script type="text/javascript">
    function HelloWorldCtrl($scope) {
        $scope.helloMessage = "Hello World from Nasir Uddin";
    }
</script>
</body>
</html>

Same thing happens if I download the angular 1.0.8 version and put it in my project folder then it's working but if i download the 1.3.14 and put it my project folder then it's not working. Please help me to find the solution.

There are improvements in AngularJs 1.3.14 and Angular 1.4.0

Now if we are using these versions then we have to create a global variable with main angular module first then create contoller with that variable and then we can use it

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

And we will create controller like this with the app variable

 app.controller('Ctrl', function($scope) {
    ....
    });

Well you can achieve this with new version in this way.

 <!DOCTYPE html>
<html ng-app="myModule">
<head>
    <meta charset="utf-8"/>
</head>
<body>
<header>
    <h1 ng-controller="HelloWorldCtrl">{{helloMessage}}</h1>
</header>

<!--<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>-->
<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
<script type="text/javascript">

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

    function HelloWorldCtrl($scope) {
        $scope.helloMessage = "Hello World from Nasir Uddin";
    }
</script>
</body>
</html>

You can read more here



EDIT CODE-


In header use like this

 <h1 ng-controller="HelloWorldCtrl" ng-bind="helloMessage"></h1>

to avoid HTML fluctuation

Due to restrictions imposed in angular 1.3 regarding global controllers, you can no longer use global controllers. Refer: https://github.com/angular/angular.js/commit/3f2232b5a181512fac23775b1df4a6ebda67d018

You need to have your controller defined within a module, which is the best practice for doing so.

Refer this code snippet for updated variation of your code which works with angular-1.3

<!DOCTYPE html>
<html ng-app='myApp'>

<head>
  <meta charset="utf-8" />
</head>

<body>
  <header>
    <h1 ng-controller="HelloWorldCtrl">{{helloMessage}}</h1>
  </header>

  <!--<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>-->
  <script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>
  <script type="text/javascript">
    var app = angular.module('myApp', []);

    app.controller('HelloWorldCtrl', function($scope) {
      $scope.helloMessage = "Hello World from Nasir Uddin";
    });
  </script>
</body>

</html>

This is a better practice of syntax for the new version

<!DOCTYPE html>
<html ng-app="app">
<head>
    <meta charset="utf-8"/>
</head>
<body>
<header>
    <h1 ng-controller="HelloWorldCtrl as ctrl">
        <span ng-bind="ctrl.helloMessage"> </span>
    </h1>
</header>

<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.0.8/angular.min.js"></script>
<!--<script src="https://ajax.googleapis.com/ajax/libs/angularjs/1.3.14/angular.min.js"></script>-->
<script type="text/javascript">

   (function(){
     angular.module('app', [])

    .controller('HelloWorldCtrl', [function(){
        var self = this;
        self.helloMessage = "HEllo World from Nasir Uddin";

     }]);

    })();
</script>
</body>
</html>

It is not recommended, since version 1.2.7, to use scope. Because scope are made in every controller or directive (ng-repeat for example). Knowing from which scope comes the data we'll be easier to maintain
