javascript OOP问题

[kmblack1]

javascript如果实现以下效果

public abstract class A
{
public A()
{
}
public void Start()
{
Work("OK");
}
protected abstract void Work(object obj);
}

public class B:A
{
public B()
{
}

protected override void Work(object obj)
{
string messgae = obj.ToString();
}
}

补充:不知道如何在子类B中重载虚方法Work

<SCRIPT LANGUAGE="JavaScript">

function A()
{
this.Start = function( Message )
{
this.Work(Message);
}
}

function B()
{

}
B.prototype = new A();

var b = new B();
b.Start("OK");

</SCRIPT>
