how get each value from json file

I try to send data to datatable in json file like bellow: exemple data of my json file:

"responseHeader":{
    "status":0,
    "QTime":2,
    "params":{
      "q":"vba",
      "indent":"true",
      "fl":"name,role_t,born,natio_t",
      "wt":"json"}},
  "response":{"numFound":7,"start":0,"docs":[
      {
        "name":"Khouli",
        "born":["1978-04-03T00:00:00Z"],
        "natio_t":"tunisien",
        "role_t":"Consultant"},
      {
        "name":"Atayi",
        "born":["1987-06-24T00:00:00Z"],
        "natio_t":"Francaise",
        "role_t":"Consultant"}
}

That is my function:

$ ( document ).ready(function() {
$.ajax({
    type: 'GET',
    url: '../search.json',
    success: function(data) {
        $.each(data, function(i, data) {
            var body = "<tr>";
            body    += "<td>" + data.name + "</td>";
            body    += "<td>" + data.born + "</td>";
            body    += "<td>" + data.natio_t + "</td>";
            body    += "<td>" + data.role_t + "</td>";

            body    += "</tr>";
            $('.datatable-ajax-source table').append(body);
        });

But I get table with undifined value

how to get this value from json files

Solution

Your input data seems to be wrong: Corrected data here:

{
"responseHeader":{
    "status":0,
    "QTime":2,
    "params":{
      "q":"vba",
      "indent":"true",
      "fl":"name,role_t,born,natio_t",
      "wt":"json"}},
      "response":{"numFound":7,"start":0,"docs":[
      {
        "name":"Khouli",
        "born":["1978-04-03T00:00:00Z"],
        "natio_t":"tunisien",
        "role_t":"Consultant"},
      {
        "name":"Atayi",
        "born":["1987-06-24T00:00:00Z"],
        "natio_t":"Francaise",
        "role_t":"Consultant"}
     ]
}
}

The proper JS to handle this:

$(document).ready(function() {
$.ajax({
type: 'GET',
url: '../search.json',
success: function(data) {
    // Data is the root node of your json response.
    // You need to navigate through the "docs" node.
    if(data.response.docs && data.response.docs.length > 0)
    {
    $.each(data.response.docs, function(i, item) {
        var body = "<tr>";

        body    += "<td>" + item.name + "</td>";
        body    += "<td>" + item.born + "</td>";
        body    += "<td>" + item.natio_t + "</td>";
        body    += "<td>" + item.role_t + "</td>";

        body    += "</tr>";
        $('.datatable-ajax-source table').append(body);
    }
    });

You are not getting the proper value for data. You should get the docs.data[i] which is, in this case, item as defined in the .each().
