Introduction to Object-Oriented JavaScript - JavaScript

Introduction to Object-Oriented JavaScript - JavaScript
Object-oriented to the core, JavaScript features powerful, flexible OOP capabilities. This article starts with an introduction to object-oriented programming, then reviews the JavaScript object model, and finally demonstrates concepts of object-oriented programming in JavaScript. This article does not describe the newer syntax for object-oriented programming in ECMAScript 6. JavaScript review If you don't feel confident about JavaScript concepts such as variables, types, functions, and scope, you can read about those topics in A re-introduction to JavaScript. You can also consult the JavaScript Guide. Object-oriented programming Object-oriented programming (OOP) is a programming paradigm that uses abstraction to create models based on the real world. OOP envisions software as a collection of cooperating objects rather than a collection of functions or simply a list of commands (as is the traditional view). Terminology Namespace Class Defines the object's characteristics. Object Property Method

Using Prototypes in Javascript | TimKadlec.com As mentioned in my previous post, I think using prototypes is powerful enough to deserve a more detailed explanation. To start off, let me say we are talking about the prototype method here, not the JavaScript library. Prototypes allow you to easily define methods to all instances of a particular object. function Pet(name, species){ this.name = name; this.species = species;}function view(){ return this.name + " is a " + this.species + "!" As you can see, by using simply using prototype when we attached the view method, we have ensured that all Pet objects have access to the view method. function Pet(name, species){ this.name = name; this.species = species;}function view(){ return this.name + " is a " + this.species + "!" We set up the Dog object, and have it call the Pet function using the call() method. Moving on, we then give Dog a custom method called bark that only Dog objects have access to. It is important to understand that prototype follows a chain.

Touch And Mouse: Together Again For The First Time Introduction For close to thirty years, desktop computing experiences have centered around a keyboard and a mouse or trackpad as our main user input devices. Over the last decade, however, smartphones and tablets have brought a new interaction paradigm: touch. This article will help you understand how touch capabilities are built into the browser, how you can integrate this new interface mechanism into your existing apps and how touch can play nicely with mouse input. The State of Touch in the Web Platform The iPhone was the first popular platform to have dedicated touch APIs built in to the web browser. My colleague Boris Smus wrote a great HTML5Rocks tutorial on Touch events that is still a good way to get started if you haven’t looked at Touch events before. All done?

Constructores en Javascript considerados ligeramente confusos Traducido del Original en el blog code.h(oe)kje. Considerando la afirmación de Flanagan 2006, (página 111) que aparece en una pregunta de comp.lang.javascript el mes pasado: En javascript, cada objeto tiene una propiedad constructor que se refiere a la función constructor que inicializa el objeto. Suena bien: hace que los constructores parezcan estáticos como las clases en Java. Pero la vida no es tan simple: ¿Qué pasa? Objetos y métodos Los objetos en Javascript son simples bolsas de propiedades con nombre que pueden ser leidas y escritas. Las funciones en javascript son objetos de primera clase. Prototipos El prototipo (prototype) de un objeto es una propiedad interna a la que me referire como "[[Prototype]]" (como en Ecma-262). Los objetos javascript pueden delegar propiedades a su [[Prototype]] (y su [[Prototype]] puede hacer lo mismo; y así hasta Object Prototype). Búsqueda de propiedades ¿Qué está pasando? Esto es lo que las propiedades prototype y [[Prototype]] parecen. Notas al pie
