You can't.

There is no upwards relationship in JavaScript.

Take for example:

var foo = {

    bar: [1,2,3]

}



var baz = {};

baz.bar = foo.bar;

The single array object now has two parents.

What you could do is something like:

var User = function User(name) {

    this.name = name;

};



User.prototype = {};

User.prototype.ShowGreetings = function () {

    alert(this.name);

};



var user = new User('For Example');

user.ShowGreetings();
