Is there any trouble with this controller method?

Every time I use routers without controllers, they work perfectly fine. But the moment I add controllers to them, my routers stop working completely. Can someone please shed some light on what might be causing this issue with my router functions?

LOGIN CONTROLLER:

angular.module('starter', ['ionic'])
.controller('LoginCtrl', function($scope, LoginService, $ionicPopup, $state) {


  $scope.login = function() {
    console.log("LOGIN user: " + $scope.username + " - PW: " + $scope.password);

    LoginService.loginUser($scope.username, $scope.password).success(function(data) {
      console.log("Login Successful");
        $state.go('home');
    }).error(function(data) {
        var alertPopup = $ionicPopup.alert({
            title: 'Login failed!',
            template: 'Please check your credentials!'
        })
    })
  }

});

ROUTERS CODE

angular.module('starter', ['ionic'])
.config(function($stateProvider, $urlRouterProvider) {
        $stateProvider
            .state('home', {
                url: '/home',
                templateUrl: 'page2.html',
                controller: 'HomeCtrl'
            })
             .state('login', {
                url: '/login',
                templateUrl: 'index.html',
                controller: 'LoginCtrl'
            })

        $urlRouterProvider.otherwise('/login');
    });

Answer №1

Your controller declaration needs to be corrected. Ensure that you do not include the injector when creating your controller within the module. Here is an example:

angular.module('app')
.controller('MainCtrl', function($scope, MainService, $ionicPopup, $state) {
   //...
});

To organize your code better, it is recommended to have separate files for your module components. You can structure it like this:

module.js

angular.module('app', ['ionic'])

config.js

angular.module('app').config(function(){});

controller.js

angular.module('app').controller('', function(){});

Answer №2

Creating a module in Angular is done using the syntax: angular.module('starter', ['ionic']) 

However, it is important to note that there is a difference between using brackets and not using them. When you include brackets like this: [], it acts as a setter method which creates a new instance of the starter module. On the other hand, if you exclude the brackets, it becomes a getter method which simply returns an already declared module.

That's why it is necessary to use:

angular.module('starter').controller('', function(){});

For more information, refer to the documentation here.

Answer №3

angular.module('mainApp', ['ngRoute']) ,

This snippet of code initializes an Angular app called mainApp. It's important to only create one instance of an app, but in this case, it's being created twice.

To properly use the app when declaring controllers or configurations, you should only use:

angular.module('mainApp')

Make sure to first create the instance and then utilize it, like so:

angular.module('mainApp', ['ngRoute']) 

This should be used in the part of your code that will execute first.
