Javascript 创建类并动态添加属性及方法的简单实现

JavaScript 是一种很强的面向对象的语言，支持创建实例之后再添加属性和方法，虽然是小技巧，用的时候容易忘记，今天写了一个很小的例子，记录在这里，仅供参考。

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";
