ASP里面令人震撼地Debug类（VBScript）

　　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
复制代码 代码如下:
<!--#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
%>

debuggingConsole.asp
复制代码 代码如下:
