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
%>
===================================================
