Incorrect return Json object

I have the following json in a local file:

    {
   "fields": {

    "input": {
        "name": "txtCpf",
        "id": "txtCpf",
        "value": "",
        "type": "text",
        "Mask": "000.000.000-00",
        "class": "input"
    },
    "input": {
        "name": "txtTelephone",
        "id": "txtTelefone",
        "value": "",
        "type": "text",
        "Mask": "(00) 00000-0000",
        "class": "input"
    },

    "button": {
        "name": "btnSave",
        "id": "btnSave",
        "value": "",
        "class": "input"
        }
   }
}

This is my javascript code:

var xmlhttp = new XMLHttpRequest();
xmlhttp.onreadystatechange = function () {
    if (this.readyState == 4 && this.status == 200) {

        myObj = JSON.parse(this.responseText);

        document.getElementById("demo").innerHTML = myObj.fields.input.name;

        Object.keys(myObj).forEach(function (item) {
            console.log(myObj.fields.input);

        });
        /* myObj.foreach(function(input){
             var fields = input.fields;
             alert(fields);
         }); */



    }
};

xmlhttp.open("GET", "mock.json", true);
xmlhttp.send();

This myObj.fields.input.name is returning only the last position of the input object so it shows txtTelephone

Would like a return of all objects of the input and not only of the last element

Using javascript only..

Correct json to :

{
    "fields": {
        "input": [{
                "name": "txtCpf",
                "id": "txtCpf",
                "value": "",
                "type": "text",
                "Mask": "000.000.000-00",
                "class": "input"
            },
            {
                "name": "txtTelephone",
                "id": "txtTelefone",
                "value": "",
                "type": "text",
                "Mask": "(00) 00000-0000",
                "class": "input"
            }
        ],
        "button": {
            "name": "btnSave",
            "id": "btnSave",
            "value": "",
            "class": "input"
        }
    }
}

to retrieve all input names, change your script to:

myObj.fields.input.forEach(function (item) {
    console.log(item.name);
})

Your json is not correct, You can't have with a json object 2 keys identical (input) If there is 2 identicals keys; the first one is overwritten with the last one.

Convert it to an array for example or change your key name.
