Javascript创建类并动态添加属性及方法的简单实现

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";
