Re: How to do class functions in javascript (aka static or shared functions)

You could Implement Polymorphism like this in JavaScript:

/** This is our Person class */

        Person = function (id, name, age) {
            this.id = id;
            this.name = name;
            this.age = age;
           // alert('A new person has been accepted');
        }

        /* definition of our Person class */
        Person.prototype = {
            /** wake person up */
            wake_up: function () {
                alert('A person is awake');
            },

            /** retrieve person's age */
            get_age: function () {
                return this.age;
            }
        }

        Inheritance_Manager = {};

        Inheritance_Manager.extend = function (subClass, baseClass) {
            function inheritance() { }
            inheritance.prototype = baseClass.prototype;
            subClass.prototype = new inheritance();
            subClass.prototype.constructor = subClass;
            subClass.baseConstructor = baseClass;
            subClass.superClass = baseClass.prototype;
        }

        Manager = function (id, name, age, salary) {
            Manager.baseConstructor.call(this, id, name, age);
            this.salary = salary;
           // alert('A manager has been registered.');
        }

        Inheritance_Manager.extend(Manager, Person);

        Manager.prototype = {
            wake_up: function () {
                alert('I am in control');
            }
        }

        var arrPeople = new Array();
        arrPeople[0] = new Person(1, 'Joe Tester', 26);
        arrPeople[1] = new Manager(1, 'Joe Tester', 26, '20.000');

        for (var i in arrPeople) {
            arrPeople[i].wake_up();
            alert(arrPeople[i].get_age());
        }
