JS Object-oriented

First, how to create an object

1.new Object ();

2.var a={};

3. Use the function to build the object as follows:

3. Constructor creates object function    person  () {        this.name= "Zhang Dan";        this.age=26;        this.gender= "female";    }    var p=new person ();//Create a new object that inherits all the properties of the template person ()     p.height=160;    Console.log (Person.prototype)//Only function has prototype, entity No, here print out or an object

　

Second, what is the object

var obj=new Object ();    Console.log (obj)

In the browser print out is as follows:

__proto__:object This is a prototype object. This property is not supported by all browsers. all objects whose final top-level objects are object. A prototype object is also an object.

Third, scope

Global variables, local variables

For example:

var a=100;//global Variables

function Test () {

var a=11;//local Variables
