clickable prototype

Use a prototype instance to specify the type of the object to be created, and copy the prototype to create a new object. The code is as follows: /*** Prototype** Use a prototype instance to specify the object type and copy the prototype to create a new object.**/Abst

The prototype pattern is one of the creation patterns, which is characterized by the "copying" of an existing instance to return a new instance, rather than a new instance. The copied instance is what we call the "prototype", which is customizable.Prototype patterns are used to create complex or time-consuming instances, because, in this case, copying an existing instance makes the program run more efficien

Structure Intention Use the prototype instance to specify the kind of object to create and create a new object by copying the prototypes. Applicability When the class to instantiate is specified at run time, for example, by dynamic loading; To avoid creating a factory class hierarchy that is parallel to the product class hierarchy; When an instance of a class can have only one

Use a prototype instance to specify the type of the object to be created, and copy the prototype to create a new object. Copy codeThe code is as follows: /** * Prototype * * Use a prototype instance to specify the object type and copy the prototype to create a new obj

When I first came into contact with this prototype I refused, I still spent a part of my time understanding this thing, not proficient, what questions to reply to belowAfter all, I was used to the bricks (funny);As I understand it, prototype is nothing more than a function of two foundations:1. Dynamically adding properties and methods of a class2. Copying the contents of the original classLet's take a look

Four. __proto__JS when creating an object (whether it is a normal object or a function object), there is a __proto__ built-in property called, which points to the prototype object that created its constructor.The object Person1 has a __proto__ property, and the constructor that creates it is person, and the prototype object of the constructor is Person.prototype, so:person1.__proto__ == Person.prototypePlea

=========================================== Objective =========================================== Recently like MooTools (encounter AH), in the public expressed his preference. Many friends ask me why I want to love each other, in fact, the reason is quite a lot. Here today I intend to enumerate some of them. Let more friends to understand MooTools, also hope to have more friends like him. The title of the article is doomed I will tell more about MooTools than

If you want to understand the internal relationship between function and object, you must introduce another two concepts dominant prototype and stealth [[prototype]] Concepts1. Prototype: Each function object has a display prototype property that represents the prototype of

Although the prototype pattern is a pattern of creation, it has nothing to do with the engineering model, and the idea of the pattern is to copy and clone an object as a prototype, and create a new object similar to the original object. This summary will be explained by the copy of the object. In Java, the Copy object is implemented through clone (), and a prototype
