Troubleshooting issues with the controller functionality in AngularJS

The following code is not producing the expected output of 'Hello, World' output: {{ greetings.text }}, world

Could someone please assist me in determining why it is not displaying 'hello, world' as intended

<!doctype html>
    <html ng-app>
    <head>
    <meta charset="utf-8">
    <title>Angular JS App 1</title>
    <script type="text/javascript" src="angular-v1.4.js"></script>
    <script type="text/javascript" src="controllers.js"></script>
    </head>

    <body>
        <div ng-controller='HelloController'> //controller
            <p>{{ greetings.text }}, World</p>
        </div>
    </body>
    </html>

Script for controller:

function HelloController($scope){
    $scope.greetings = {text : 'hello'};
}

Answer №1

It is not allowed to use global controller starting from version 1.3.x

You can try implementing it like this:

var app = angular.module("app", []);
app.controller("HelloController", function($scope) {
    $scope.greetings = {
        text: 'hello world'
    }
});

To include the module name in HTML, use the following:

Add the module name:

<html ng-app="app">

Answer №2

Make sure to include the module name in ng-app directive:

<div ng-app='app'>
</div>

Following this structure, your code should look like this:

<script>
  angular.module('app', [])
    .controller('testCtrl', ['$scope', function($scope){
      $scope.test ="hello world";
    }])
</script>

Answer №3

To utilize the functionality of AngularJS, it is essential to specify the value for the ng-app directive.

For example:

<html ng-app="myAngularApp">

Additionally, ensure that the angular module named myAngularApp is defined within your script.
