在ASP VBScript中的自我引用

我们在用ASP进行开发时会用到简单的OOP类,但是如果有一个像JAVA和PHP的this这样的东西就更好了。

关键字: Me

其他语言使用 this 或者 self 访问当前对象. VBScript的关键字就是: Me

<%
Class meClass
    Private i_count
    Public Property Get Count
        i_count = i_count + 1
        Count = i_count
    End Property
    Public Property Get countTwice
        countTwice = Me.Count + Me.Count
    End Property
    Public Property Let Count(c)
        i_count = c
    End Property
End Class
%>

 

测试一下:

<%
Dim meTest
Set meTest = New meClass
meTest.Count = 10
Response.Write(meTest.countTwice)
Set meTest = Nothing
%>

显示的值是:23也就是11 + 12。说明每次的Me.count都进行了自我引用。
