I’m trying to create a table for a football championship with the return of a json:
To facilitate I will put the Json below refers only to a Team:

{
   "id": "1",
   "nome": "Palmeiras",
   "Atleta": [
      {
         "id": "0",
         "nome": "Fernando Prass",
         "idade": "1",
         "FichaTecnica": [
            {
               "id": "1",
               "posicao": "goleiro",
               "camisa": "12"
            },
            {
               "id": "2",
               "posicao": "zaga",
               "camisa": "11"
            },
            {
               "id": "3",
               "posicao": "meia",
               "camisa": "9"
            },
            {
               "id": "4",
               "posicao": "zaga",
               "camisa": "7"
            },
            {
               "id": "5",
               "posicao": "meia",
               "camisa": "5"
            },
            {
               "id": "6",
               "posicao": "ataque",
               "camisa": "3"
            }
         ]
      }
   ]
}{
            'id': '2',
                'nome': 'Conrinthias',
                    'Atleta': [
                        {
                            'id': '0',
                            'nome': 'Cássio',
                            'idade': '1',
                            'FichaTecnica': [
                                {
                                    'id': '1',
                                    'posicao': 'goleiro',
                                    'camisa': '1'
                                },
                                {
                                    'id': '2',
                                    'posicao': 'zaga',
                                    'camisa': '22'
                                },
                                {
                                    'id': '3',
                                    'posicao': 'meia',
                                    'camisa': '5'
                                },
                                {
                                    'id': '4',
                                    'posicao': 'zaga',
                                    'camisa': '7'
                                },
                                {
                                    'id': '5',
                                    'posicao': 'meia',
                                    'camisa': '8'
                                },
                                {
                                    'id': '6',
                                    'posicao': 'ataque',
                                    'camisa': '6'
                                }
                            ]
                        }
                    ]
        }

The Code to read Json is as follows:

@section Scripts{

    <script type="text/javascript">

        $(document).ready(function () {

            var valorRetornado= //É o Json exemplificado acima.

            // convertendo a string em objeto
            var obj = JSON.parse(valorRetornado);

            obj.forEach(function (o, index) {
                console.log(o.id);
            });
        });

    </script>
}

The problem I’m facing is the following mistake:

Uncaught ReferenceError: valorRetornado is not defined
    at HTMLDocument.<anonymous> (Index:61)
    at fire (jquery-1.10.2.js:3062)
    at Object.fireWith [as resolveWith] (jquery-1.10.2.js:3174)
    at Function.ready (jquery-1.10.2.js:447)
    at HTMLDocument.completed (jquery-1.10.2.js:118)

where you got the variable value?

its obj is not eternal so it does not have the foreach function, only the athletes from inside it, so: obj.Atleta.foreach(Function(o,index){ console.log(o. id); });

I added one more Team to Json, there may be several teams.

Your JSON is missing the array setting for players and the comma to separate one player from the other, try using the file below:

    [{
       "id": "1",
       "nome": "Palmeiras",
       "Atleta": [
          {
             "id": "0",
             "nome": "Fernando Prass",
             "idade": "1",
             "FichaTecnica": [
                {
                   "id": "1",
                   "posicao": "goleiro",
                   "camisa": "12"
                },
                {
                   "id": "2",
                   "posicao": "zaga",
                   "camisa": "11"
                },
                {
                   "id": "3",
                   "posicao": "meia",
                   "camisa": "9"

Your json is not in a correct pattern, the right thing would be to do something more or less like this:

{"Times":[{
   "id": "1",
   "nome": "Palmeiras",
   "Atleta": [
      {
         "id": "0",
         "nome": "Fernando Prass",
         "idade": "1",
         "FichaTecnica": [
            {
               "id": "1",
               "posicao": "goleiro",
               "camisa": "12"
            },
            {
               "id": "2",
               "posicao": "zaga",
               "camisa": "11"
            },
            {
               "id": "3",
               "posicao": "meia",
               "camisa": "9"
            },
            {
               "id": "4",
               "posicao": "zaga",
               "camisa": "7"
            },
            {
               "id": "5",
               "posicao": "meia",
               "camisa": "5"
            },
            {
               "id": "6",
               "posicao": "ataque",
               "camisa": "3"
            }
         ]
      }
   ]
},

                            "id": "0",
                            "nome": "Cássio",
                            "idade": "1",
                            "FichaTecnica": [
                                {

                                {
                                    "id": "2",
                                    "posicao": "zaga",
                                    "camisa": "22"
                                },
                                {
                                    "id": "3",
                                    "posicao": "meia",
                                    "camisa": "5"
                                },
                                {
                                    "id": "4",
                                    "posicao": "zaga",
                                    "camisa": "7"
                                },
                                {
                                    "id": "5",
                                    "posicao": "meia",
                                    "camisa": "8"
                                },
                                {
                                    "id": "6",
                                    "posicao": "ataque",
                                    "camisa": "6"
                                }
                            ]
                        }
                    ]
        }
        ]
        }

then to iterate for them just do the following;

obj.Times.forEach(function(o,index){ console.log(o.id); })
