JavaScript Object-oriented

Referencing a type in JavaScript is a data structure that is organized together. It is also often called a class, but there is no concept of class in JavaScript. Although JavaScript is an object-oriented language, it does not have the basic structure of classes and interfaces supported by traditional object-oriented languages.

How to create an array, there are three ways to create an array in the script:

1.new operator

var user = new Objcet ();
User.Name = "John";
user.age=20;
user.sex= "Male";

2. Object literal Volume

var user ={       name = "John", Age       =,       sex = "male"}
Note: When you create an object with a literal, it ends with "," but the last property is not followed by a comma.

3. Traditional complex ways

var user = {}; User.Name = "John"; User.age = 20; User.sex = "male";

How objects are invoked

There are two ways to invoke an object:

Method 1:

Alert (User.Name + "" +user.age);  Return to ' Zhang 320 '

Method 2:

Alert (user[' name '] + "" +user[' age ');  Return to ' Zhang 320 '

Add method

var user = {
name: "John",
age:20,
sex: "Male",
info:function () {
alert (THIS.N Ame+ "" +this.age+ "" +this.sex);
showhello:showhello//Add methods outside of object to object
}
functi   On Showhello () {
alert ("hello!");  
}
User.info (); Two methods of invocation
User.showhello ();
