OOP Javascript Inheritance

// Inheritance
function RunSampleE() {

   var Dog = function (id, name, age, color) {
       Dog.prototype.Color = color;
       Dog.prototype.Age = age;
       Dog.prototype.ID = id;
       Dog.prototype.Name = name;
       Dog.prototype.toString = function () {
           return this.ID + '; ' + this.Name + '; ' + this.Age + '; ' + this.Color;
       }
       Dog.prototype.Bark = function () { alert('Hoow, Hoow'); }
   }

   // var buddy = new Dog(1, 'Buddy', 3, 'White');
   var buddy = new Dog.prototype.constructor(1, 'Buddy', 3, 'White');
   alert(buddy);
   buddy.Bark();
   Dog.prototype.New = function () { alert('Say new'); }
   buddy.New();
}

OOP Javascript (Hints)

Hints

• Use Visual studio 2010, for writing all the code, it support intellisense
• Use /// , inside the Javascript file to reference other just to support intellisense
• when you define function as class, like

  var Dog = function (id, name, age, color) {
          this.Color = color;
          this.Age = age;
          this.ID = id;}  //you cannot use Dog.Color [Wrong]
  
  you have to initiate the object first like
  
  var buddy = new Dog(1, 'Buddy', 3, 'White');
  then you will call buddy.Color.
