Javascript 建立類別並動態添加屬性及方法的簡單實現

JavaScript 是一種很強的物件導向的語言，支援創建實例之後再添加屬性和方法，雖然是小技巧，用的時候容易忘記，今天寫了一個很小的例子，記錄在這裡，僅供參考。

function MyClass()
{ 
  //This function is same as a constructer 
  alert("New Object Created"); 
}
//Creating Object 
var MyObject = new MyClass (); 
NewObject.prototype = 
{ 
  //Adding Method named "MyMethod" 
  MyMethod: function(){alert("My Method");} , 
   
  //Adding property named "MyProperty" 
  MyProperty: "My Property" 
}
  
//Calling Method 
MyObject.MyMethod(); 
  
//Assigning Property 
MyObject.MyProperty = "My Property Value changed";
