ASP中的DEBUG类(VBSCRIPT)
不知道用ASP写代码的朋友是不是和我有相同的感受，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式“response.write ”，然后输出相关的语句来看看是否准确。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！

使用方式很简朴：

test.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

<%
Class debuggingConsole

private dbg_Enabled
private dbg_Show
private dbg_RequestTime
private dbg_FinishTime
private dbg_Data
private dbg_DB_Data
private dbg_AllVars
private dbg_Show_default
private DivSets(2)

\\\'Construktor => set the default values
