ASP中令人震撼的Debug类（VBScript）

译者的话：

不知道用ASP写代码的朋友是不是和我有一样的感受，ASP中最头疼的就是调试程序的时候不方便，我想可能很多朋友都会用这样的方法“response.write ”，然后输出相关的语句来看看是否正确。前几天写了一个千行的页面，里面大概有七八个SUB/FUNCTION，调试的时候用了有三十几个response.write ，天，调试完后把这三十个一个个删除，累！

今天看到一个ASP中的Debug类（VBS），试用了一下，绝！

使用方法很简单：

test.asp

<!--#INCLUDE FILE="debuggingConsole.asp"-->

<%

output="XXXX"

Set debugstr = New debuggingConsole

debugstr.Enabled = true

debugstr.Print "参数output的值", output

'……

debugstr.draw

Set debugstr = Nothing

%>
