JavaScript Example Method for Defining Global Objects

This article illustrates how JavaScript defines global objects. Share it for your reference, as follows:

!function (factory) {
  factory(window['Hi'] = {
    __a: function () {
    __b: function () {
    __c: function () {
}(function (Hi) {
  if (typeof Hi === undefined) {
    Hi = {};
  Object.defineProperty(Hi, 'appName', {
    get: function () {
      return 'this is app name.';
console.log(Hi.appName);//this is app name.

Pass the object (Hi) definition function as an argument (factory) to the immediate execution function through the immediate execution function

!function (factory) { }();

In an immediate execution function, the object to be defined is passed as an argument to the immediate execution function's argument function.

The following can also implement the same object definition:

var myObj = myObj || {};
(function (myObj) {
  myObj.__a = function () {
  }; = 'this is';
console.log(;//this is

These definition methods are relatively independent and can be saved and used as functional modules of the Party Capital.

Similar to Jquery plug-in writing.
