MVC-based JavaScript web rich Application Development: MVC and Classes

Create class:

 VaR Class = Function  (Parent ){  VaR Klass = Function  (){  This . Init. Apply ( This  , Arguments );};  If  (Parent ){  VaR Subclass = Function  () {}; Subclass. Prototype = Parent. Prototype; Klass. Prototype = New  Subclass;} Klass. Prototype. init = Function  () {}; Klass. FN = Klass. Prototype; Klass. FN. Parent = Klass; Klass. Proxy = Function  (Func ){  VaR Self = This  ;  Return ( Function  () {Func. Apply (self, arguments) ;}) ;}; Klass. FN. Proxy = Klass. Proxy; Klass. Extend = Function  (OBJ ){  VaR Extended = OBJ. extended;  For ( VaR I In  OBJ) {Klass [I] = OBJ [I];} If  (Extended) extended (Klass)}; Klass. Include = Function  (OBJ ){  VaR Required DED = OBJ. included;  For ( VaR I In  OBJ) {Klass. FN [I] = OBJ [I];}  If  (Sorted DED) Sorted ded (Klass )}; Return  Klass ;}; 

Demo:

 VaR Person = New  Class; person. Include ({init:  Function  (Name, age ){  This . Name = Name;  This . Age = person. checkage (AGE )? Age: Null  ;}, Sayhello:  Function  () {Console. Log ( "Hi, my name is" + This . Name + ( This . Age? ", I am" + This . Age + "years old this year ":"" ) ;}}); Person. Extend ({needwater:  True  , Checkage:  Function  (AGE ){  Return Age> 0 & age <150 ;}});  VaR Jim = New Person ("Jim", 10); Jim. sayhello ();  //  Output: Hi, my name is Jim, I am 10 years old this year  VaR Tom = New Person ("Tom",-1 ); Tom. sayhello ();  //  Output: Hi, my name is Tom 

There are static attributes and methods in extend, and instance attributes and methods in include.

When attributes and methods are irrelevant to or public to specific instances, use static attributes and Methods. Otherwise, use instance attributes and methods.
