How to access class variables from inner prototype - javascript

JavaScript's prototype-based class system does not allow this.
MyClass's prototype will be shared between all instances of the class. In the following code, both instances will use the same function instance...

var first = new MyClass(), second = new MyClass();
first.nested.myFunc2(); <-- Same prototype function
seecond.nested.myFunc2(); <-- Same prototype function

When the code enters the "myFunc2" definition, which parent should it be accessing?

If you need access to the parent's "this" value, you'll have to use a closure and set up the nested object in the parent constructor as below.

var MyClass = null;

(function() {
    MyClass = function() {
        this.clsVar = "I'm inside constructor";
        var that = this;
        this.nested = {
            myFunc2: function() {
                console.log("I'm func2 accessing constructor variable : " + that.clsVar); // I know, this will never point to the class scope
            }

         }
    };

    MyClass.prototype = {
        constructor: MyClass,
        myFunc1: function() {
            console.log("I'm func1 accessing constructor variable : " + this.clsVar);
        }
    }
}())
