asp下調(diào)試程序的debug類

ASP中最頭疼的就是調(diào)試程序的時(shí)候不方便，我想可能很多朋友都會(huì)用這樣的方法“response.write ”，然后輸出相關(guān)的語(yǔ)句來(lái)看看是否正確。前幾天寫(xiě)了一個(gè)千行的頁(yè)面，里面大概有七八個(gè)SUB/FUNCTION，調(diào)試的時(shí)候用了有三十幾個(gè) response.write ，天，調(diào)試完后把這三十個(gè)一個(gè)個(gè)刪除，累！

今天看到一個(gè)ASP中的Debug類（VBS），試用了一下，絕！

使用方法很簡(jiǎn)單：

test.asp

!--#INCLUDE FILE="debuggingConsole.asp"-->
%
output="XXXX"
Set debugstr = New debuggingConsole
debugstr.Enabled = true
debugstr.Print "參數(shù)output的值", output
''……
debugstr.draw
Set debugstr = Nothing
%>
