How JavaScript creates an object summary (4 ways) _javascript Tips

The example in this article summarizes the way JavaScript creates objects. Share to everyone for your reference, specific as follows:

Subconsciously, JavaScript is not an object-oriented language, it can only be said to be an object-oriented language, at least it is not good to match the three basic object-oriented characteristics (inheritance, encapsulation, polymorphism), of course, many people think that JavaScript is an object-oriented language, It seems to be true, because object-oriented can also be implemented in JavaScript, such as inheritance, encapsulation bar can also be implemented in JavaScript, but easy to implement? So I feel very puzzled. See the Internet has a netizen evaluation is very good, "object-oriented is just a thought, language can only say whether it is good to support object-oriented features." "If you have a certain understanding of object-oriented, and C can also write object-oriented programs, JavaScript is also the case." So say can not assert that JavaScript is object-oriented language, hehe, think it is a rookie, dare not jump from the assertion, or look at the code:

1. Creating Objects with JSON

var company = {};
Company.name= ' Huawei ';
company.address = ' Beijing ';
Company.produce = function (message)
{
 alert (message);
}

2. Using the object type in JavaScript

company= new Object ();
Company.name= ' Taobao ';
company.address = ' Hangzhou ';
company.produce= function (message)
{
 alert (message);
}

3. Create a function to generate an object

Company = function ()
{
  this.name = ' sina ';
  this.address = ' Beijing ';
  This.produce = function (message)
  {
  alert (message);
  }
}

4. Using the browser Window object

Window.name = ' Tencent ';
window.address = ' Beijing ';
Window.produce = function (message)
{
  alert (message);
}

Extended:

1. Object replication

Emptyobject = new Object ();
company.apply = function (o, C,)
{
  if (o && c && typeof c = = ' object ')
  {for
  (Var p in c)
  {
  O[p] = c[p];
  }
  return o;
};
Emptyobject = ext.apply (Emptyobject,company);

2. Object replication (function method)

var copyoo = new Function ();
Copyoo.prototype = Company;
var newcopyoo = new Copyoo ();

I hope this article will help you with JavaScript programming.
