How to pass JSON Object content to a controller

Question

How do I pass the contents of the service JSON object to controller.

At the moment I do tests with the following codes:

Controller(app.js)

  example.controller('equipecontrol', ['EquipeService','$scope', function( EquipeService,$scope) {      

Parse.initialize('APPLICATION_ID', 'JAVASCRIPT_KEY'); 
Parse.serverURL = 'https://parseapi.back4app.com';

EquipeService.$inject = ['EquipeService']; // Injetamos o service

equipes =  { "nomejogador": '',
             "posioriginal":'',
             "nomedotime": '',
             "jogoude": ''
            };

listaobjEquipes = EquipeService.listaobjEquipes;   <--- NESTE MOMENTO O OBJETO ESTÁ RETORNANDO VAZIO

...

Service(service.js)

var example = angular.module('starter')
example.service('EquipeService', ['$http', function($http) {
  var aDadosEscalacao = {};
  return { listaobjEquipes: aDadosEscalacao,
        get: function(param) {
          var nteste = 1
          if (neste = 1) {
            idjogador = '1';
            idtime = '1';
            idjogoude = '1';
            idpelada = '1';
            ngolsjogador = '207';
            faltastxtJSON = '1';
            ncrtamarelos = '1';
            ncrtvermelhos = '1';
            nptoscraque = '18';
            nptosdestaque = '19';
            nptosmaster = '21';
            nptosgoleiro = '12';
            aDadosEscalacao = { "idjogador": idjogador, 
                                "idtime": idtime,
                                "idjogoude": idjogoude,
                                "idpelada": idpelada,
                                "gols": ngolsjogador,
                                "faltas": faltastxtJSON,
                                "cartao_amarelo": ncrtamarelos,
                                "cartao_vermelho": ncrtvermelhos,
                                "pontuacaocraque": nptoscraque,
                                "pontuacaodestaque": nptosdestaque,
                                "pontuacaomaster": nptosmaster,
                                "pontuacaogoleiro": nptosgoleiro };
          }
          return aDadosEscalacao
        }
  }
}])

I ask, what is wrong with the code that cannot pass the content of JSON completed for the controller?

Answer 1

You have some problems in this function. If you use $http, that you inject but do not use, you will have asynchronous problems, but let’s focus on the current problem.

You are using a method of your service that simply returns the value of the variable aDadosEscalacao. As you define an empty object, it simply returns that object.

To return the correct value, you need to run the method get which you have defined, which in this case fills the variable and returns with the correct value.

Just change

listaobjEquipes = EquipeService.listaobjEquipes;

To:

listaobjEquipes = EquipeService.get();
