ASP中最頭疼的就是調試程序的時候不方便，我想可能很多朋友都會用這樣的方法“response.write”，然后輸出相關的語句來看看是否正確。前幾天寫了一個千行的頁面，里面大概有七八個SUB/FUNCTION，調試的時候用了有三十幾個response.write，天，調試完后把這三十個一個個刪除，累!

今天看到一個ASP中的Debug類(VBS)，試用了一下，絕!

使用方法很簡單：

test.asp

<%

output="XXXX"

Set debugstr = New debuggingConsole

debugstr.Enabled = true

debugstr.Print "參數output的值", output

''……

debugstr.draw

Set debugstr = Nothing

%>
