AJAX Object.length undefined in JavaScript

objectkey.txt

IF YOU ARE HAVING PROBLEM ON USING AJAX JSON AND THE DATA IS  "UNDEFINED" AND CANNOT COUNT THE LENGHT.
I WOULD RECOMMEND TO USE THIS.

var jsonDataFromAjax = {};

var keys = Object.keys(jsonDataFromAjax);

for (var i = 0, len = keys.length; i < len; i++) {
  console.log(jsonDataFromAjax[keys[i]]);
}
