Javascript object-oriented programming, a complete inheritance example

Parent class

Function Person (name) {this. name = name;} Person. prototype. getName = function () {return this. name ;}

Public method:

Function extend (subClass, superClass) {var F = function () {}; F. prototype = superClass. prototype; subClass. prototype = new F (); subClass. prototype. constructor = subClass; subClass. superclass = superClass. prototype; if (superClass. prototype. constructor = Object. prototype. constructor) {superClass. prototype. constructor = superClass ;}}

Subclass:

Function Author (name, books) {Author. superclass. constructor. call (this, name); this. books = books;} extend (Author, Person); Author. prototype. getBooks = function () {return this. books ;}; Author. prototype. getName = function () {var name = Author. superclass. getName. call (this); return name + ', Author of' + this. getBooks (). join (',');};
