Accessing private member variables from prototype-defined functions

Question

Is there any way to make “private” variables (those defined in the constructor), available to prototype-defined methods?

TestClass = function(){
    var priv         


        

Answer 1

There is a very simple way to do this

function SharedPrivate(){
  var private = "secret";
  this.constructor.prototype.getP = function(){return private}
  this.constructor.prototype.setP = function(v){ private = v;}
}

var o1 = new SharedPrivate();
var o2 = new SharedPrivate();

console.log(o1.getP()); // secret
console.log(o2.getP()); // secret
o1.setP("Pentax Full Frame K1 is on sale..!");
console.log(o1.getP()); // Pentax Full Frame K1 is on sale..!
console.log(o2.getP()); // Pentax Full Frame K1 is on sale..!
o2.setP("And it's only for $1,795._");
console.log(o1.getP()); // And it's only for $1,795._
