This article turns from HTTP://WWW.YIIBAI.COM/DEMO/4This article is about JS object-oriented implementation, easy to understand. Worth collecting.This example is primarily object-oriented JavaScript programming, and learning to write concise

Today, the content of the study is JS object-oriented programming, the following summary of all the content from Ruan Yi Feng Big blog, interested children can poke the original linkHttp://www.ruanyifeng.com/blog/2010/05/object-oriented_javascript_encapsulation.htmlTrue, easy to understand, at the same time the first question of the

Oldobj is an object, not a value For example Var newobj=oldobj; If you want to oldobj change the time does not affect the newobj; You can write a function like this Copy Code code as follows: function Clone (myobj) { if (typeof (MyObj)!= ' object ') return myobj; if (myobj = null) return myobj; var mynewobj = new Object (); for (var i in m

a static method, in the same way, we can improve the closure form of the definition:varSingleton = (function(){ varUnique; functiongetinstance () {if(!unique) {Unique=construct (); returnUnique; } } functionconstruct () {varPrivate_member; functionPrivate_method () {}return{//This is the real singleton.Public_member: ", Public_method:function(){} };}) ();This method calls a singleton object:Singleton.getinstance (). Publicmethod ();This will only really create a unique

There are several ways to build a class in javascript: 1.Factory Mode Copy Code code as follows: function Createcar () { var car = new Object (); Car.color= "B"; car.length=1; Car.run=function () {alert ("Run");} return car; } Once you have defined such a function, you can use: var car1 = Createcar (); var car2 = Createcar (); To create a new

These things were clear to me before, but they were not explained, nor did they delve into these things. Today, while watching "Understanding through JavaScript", I saw the author's description, "Latrine" opened. The present excerpt is as follows, and the author says it is clear: The process of creating objects in the form of var anobject = new Afunction () can actually be divided into three steps: The first step is to create a new

new to instantiate an object. It is more convenient to use. So we define another object to encapsulate the above mentioned o object: Var k = function (){ Return new o (); } In this way, we can call: K (). action1 (). action2 (); I recommend a method called "function-based" to construct JS. The Code is as follows: // Bold to emphasize// This method is fully

Copy Code code as follows: A.prototype.funx = function () {alert (x)}; A.prototype.funy = function () {alert (y)}; These two codes define two methods, namely Funx and Funy. So if there's a situation now, what if we need to add a method to the a function temporarily? Copy Code code as follows: function A (x,y) { this.x = x; This.y = y; } A.prototype.funx = function () {alert ("5")}; var obj = new A (5,10); alert (obj.x); alert (OBJ.Y);
