    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:
