JavaScript class definition Summary

A variety of JavaScript definition classes can be found online:

1.ECMAScript defining a Class or object

Three ways to define classes (class) in 2.Javascript

I want to sort out a "concise" class definition template that implements the modularity of the code.

First, the name space

// Root Namespace var Root; if (! Root) root={}; .. // Level Two namespaces if (! Root.secondns) root.secondns={};

Such.

Ii. definition of Class

Implement code modularity by defining classes <script>

        //#region class: MyClass1 (Support folding: details click)        varmyclass1=function () {//Public Property             This. publicprop1=1; //Private Property             This. PRV = {};  This. PRV.PROP1 =2; //method, static property initialization            if(typeofmyclass1._initialized = ="undefined") {                //Method of publicmyclass1.prototype.publicop1=function () { This. PRV.PROP1 + =5;  This. PUBLICPROP1 + =6; Console.log ("privateprop1="+ This. prv.prop1+", publicprop1="+ This. PublicProp1); }                //Method of PrivateMYCLASS1.PROTOTYPE.PRV = {}; MYCLASS1.PROTOTYPE.PRV.OP1=function () {}//static properties (accessed through the class name)myclass1.staticprop1="STATICPROP1"; Myclass1._initialized=true; }        }        //#endregion class: MyClass1//Test        varx =NewMyClass1 (); X.PUBLICOP1 ();        vary =NewMyClass1 (); Y.PUBLICOP1 ();

        Console.log ("myclass1.staticprop1=" + myclass1.staticprop1);        myclass1.staticprop1= "NewValue"
Console.log ("myclass1.staticprop1=" +</script>

Iii. inheritance

Do not consider

Iv. Hierarchy of modules

Through the combination of namespace and class, the program module is implemented hierarchically.

// Root Namespace root={root attribute 1: attribute value, Root method 1:function () {...}, class 1:function () {Class 1 definition), Class 2:new function () {Class 2 definition),/ / single / / Two-level namespace secondns:{...};
