Why private variables in an anonymous function are accessible from outside the function in javascript?

will help you What you're experiencing is lexical scoping in JavaScript. Basically, whenever you execute a function, you have access to that function's scope. In addition to that though, you also have access to the lexical scope in which the function was defined.
Let's take a look at an example:
var someObject = (function () {
  var privateVariable = 18;

  var getValue = function () {
    return privateVariable;

  return {
    getValue: getValue

Modify variables from an anonymous function in javascript

should help you out This is because ajax is async. This means the ajaxcall is still doing its thing, and you are allready returning 'response'.
If you need 'response' for something (which I kinda asume), do something with it in the oncomplete of the ajaxcall. The function you use in the get is the function that gets trigger oncomplete.

Passing JavaScript variables to anonymous function

should help you out I have fixed the issue, as stated in my 3rd update, the problem was the inputs were in a div with display: none that makes it hidden at page load and only shown later when a button click shows it. The problem lies in how it's shown.
My old approach was copying the HTML enclosed in a div with display: none and id #commentForm to an empty div using the append() method, which caused the input IDs to be present 2 times in the page and thus the $() selector return an empty value.

I wish this help you You can use a Revealing module pattern to expose a Public API and consume it from other modules.
//Example papa function

var papa = (function(){
  console.log('I am Papa'); 
  //I do other stuff too
  getAdvice : function() {
    console.log('Work hard');
  getHelp : function() {
    console.log('Give Help');
  getMoney : function() {
  return {
      getAdvice: getAdvice,
      getHelp: getHelp,
      getMoney: getMoney

//Example Child function
var child = (function(papa){
  console.log('I am Child'); 

  //use PAPA functions as required

I wish this helpful for you No it's not possible without changing the code which you have.
As you mentioned you cannot change the code, you cannot read the private variable. The reason for making a variable private is to make sure you cannot read and write it from outside the scope. If at all that is possible then the meaning and the reason of private variable is lost.
