Encountering issues with scope: Unable to retrieve value and receiving an error message stating 'Cannot assign value to undefined property'

var mainApp = angular.module("Main", []);

mainApp.controller("CtrlMain", [ function ($scope) {
    $scope.amount = 545
}]);` 
var app = angular.module("Main", []);

app.controller("MainCtrl", [ function ($scope) {
    $scope.value = 545
}]);

Answer №1

Your Dependency Injection is incorrect, you must include $scope as both an argument and in the array.

app.controller("MainCtrl", ["$scope", function ($scope) {
    $scope.value = 545
}]);

Alternatively, you can use this method:

app.controller("MainCtrl", function ($scope) {
    $scope.value = 545
});

The first approach is recommended as the second one may only work for unminified code.

Answer №2

Dependency Injection may not be the best approach here. Let's give this a try:

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

    app.controller("MainCtrl", [ "$scope", function ($scope) {
      $scope.value = 545
    }]);
