Pseudo-class Declaration

Original address: Http://javascript.info/tutorial/pseudo-classical-pattern#pseudo-class-declaration

A Pseudo-class consists of the constructor function and methods.
For example, here's the Pseudo-class with single method and both Animal sit properties.

function Animal (name) {  THIS.name = Name}animal.prototype = {   canwalk:true,  sit:function () {    This.canwalk = False    alert (THIS.name + ' sits down. ')  }} var animal = new Animal (' Pet ')//(1) alert (animal.canwalk)//Trueanimal.sit ()             //(2) alert (Animal.canwalk)//False

　　

1. When new Animal(name) was called, the new object recieves __proto__ reference to, see this on Animal.prototype the "the" picture.
2. Method animal.sit Changes animal.canWalk in the instance, so now this animal object can ' t walk. But the other animals still can.

The scheme for a pseudo-class:

• Methods and Default properties is in prototype.
• Methods prototype in use this , which are the current object because the value of only depend on the this calling Co ntext, so animal.sit() would set this to animal .
