Angular fails to display the $scope

When I attempt to display a variable from my controller, the output shows as {{UserCtrl.user}} instead of the actual content stored in UserCtrl.user.

My file structure is as follows:

  • index.html
  • scripts/app.js

Below is the code snippet from index.html:

<!doctype html>
<html lang="en" ng-app="birdsnest">
<head>
    <meta charset="utf-8">

    <title>Birdsnest</title>

    <link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap.css">
    <link rel="stylesheet" href="bower_components/bootstrap/dist/css/bootstrap-theme.css">
</head>
<body>
    <div ng-controller="UserController as UserCtrl">
        {{UserCtrl.user}}
    </div>

    <script src="bower_components/jquery/dist/jquery.js"></script>
    <script src="bower_components/bootstrap/dist/js/bootstrap.js"></script>
    <script src="bower_components/angular/angular.js"></script>

    <script src="scripts/app.js"></script>
</body>
</html>

The contents of scripts/app.js are listed below:

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

  app.controller('UserController', ['scope', function($scope) {
    $scope.user = 'Michael';
  }]);
})();

Answer №1

Revise the following line:

app.controller('UserController', ['scope', function($scope) {

To:

 app.controller('UserController', ['$scope', function($scope) {

Modify: If you are utilizing controllerAs, then it is advisable to adjust your code in this manner:

app.controller('UserController', function() {
  this.user = 'Michael';
}); 

Answer №2

When implementing the ControllerAs syntax in your HTML, the values that are bound to the controller instance reside within the this object.

This suggests that the code snippet assigning user to the scope object is not accurate; instead, consider the following approach:

app.controller("UserController", function() {
  this.user = "Michael";
});
