【转贴】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

%>

===================================================

debuggingConsole.asp
