Having trouble getting the controller to recognize the factory or service

Question

Having trouble getting the controller to recognize the factory or service

I am facing an issue with getting this factory recognized in my other controllers so that I can inject a result object into them.

myApp.factory('resultService', function(){

function SampleService() {
this.result = [];
}
});

This code is from my controller, with some parts removed that are not relevant to the question.

myApp.controller('125Zero', ['$scope','ngAudio', function($scope, ngAudio, SampleService){ 

    $scope.buttonPressed= function() {
   var tempObj = {};
       tempObj.title = $scope.title;
       tempObj.frequency = $scope.frequency; 
console.log(tempObj);

        SampleService.result.push($scope.tempObj);
} 
}]);

I am consistently getting a TypeError: Cannot read property 'result' of undefined.

I realize it might be a small mistake that I have overlooked.

Answer №1

myApp.controller('125Zero', ['$scope','ngAudio', function($scope, ngAudio, SampleService){

You have not included SampleService in the array of dependencies.

myApp.controller('125Zero', ['$scope','ngAudio', 'resultService', function($scope, ngAudio, resultService){

Addtionally, ensure that you are returning an object from the factory. At the moment, no return statement is present.

This is the solution for you

myApp.factory('dataService', function(){

myApp.controller('987Omega', ['$scope','ngSound', 'dataService', function($scope, ngSound, SampleService, dataService){ 
    $scope.clickButton= function() {
        var tempObj = {};
       tempObj.name = $scope.name;
       tempObj.value = $scope.value; 
       console.log(tempObj);

       dataService.data.push($scope.tempObj);
    } 
}]);
