declaring vars inside object gives me error

Question

I am trying to create variables inside object as follows but it is giving me error. Here is DEMO

And same code is below

var One = {
    var var1, var2;
    init: function () {
      var1 = 'some1';
      var2 = 'some2';
    }        
}

One.init();

What are you trying to achieve? Should `var1` and `var2` be accessible outside of the `init` function? Why are they not properties of `One`? — James Allardice, Nov 06 '12 at 11:09
I want these vars to be accessible inside `One` object but must not be accessible outside of it so that if I want to declare vars with the same name in other files should not create any conflicts — Om3ga, Nov 06 '12 at 11:11
I think that init function is mainly for initialization. Am I right? — Om3ga, Nov 06 '12 at 11:13

Objecs have properties not variables:

var One = {
    prop: "",
    prop2: "",
    init: function() {
       this.prop = 'some1';
       this.prop2 = 'some2';
    }        
}

Can I declare variables with the same name in other files? Will it create any conflicts with these one if I follow your procedure? – Om3ga Nov 06 '12 at 11:16

@x4f4r Yes, you can, there is no conflict between properties of an object and variables. – Ram Nov 06 '12 at 11:18
Thanks for helping me out but could you tell me that can I declare public and private properties using object literal? – Om3ga Nov 06 '12 at 12:07
@x4f4r The object-oriented features of JavaScript differ from other languages like PHP, there is no _private_ or _public_ keyword in JavaScript. – Ram Nov 06 '12 at 12:14

Object should look like this:

var Object = {

  /**
   * Documantation.
   */
  var1: null,

  /**
   * Documantation.
   */
  var2: null,

  /**
   * Documantation.
   */
  init: function () {
    this.var1 = 'some1';
    this.var2 = 'some1';
  }
};

Object.init();

But more information about the task to accomplish would be great, to be more clear with the answer.

There concept of 'file' is no applicable in javascript, the variables are part of an object, so you will have conflicts only if you use the same object: `Object.var1 = "I'm changing var1 value";`. You should read more about javascript objects and scope. You have some information [Here](http://stackoverflow.com/questions/133973/how-does-this-keyword-work-within-a-javascript-object-literal) and [here](http://www.quirksmode.org/js/this.html). – Chango Nov 06 '12 at 11:26

As an alternative, you can do this:

function One(Var1, Var2)
{
    this.var1 = Var1;
    this.var2 = Var2;
}

var OneExample = new One('some1','some2');

var OneExampleVar1 = OneExample.var1;

EDIT - Here is a fiddle demo
