asp下调试程序的debug类
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 <% 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 Private Sub Class_Initialize() dbg_RequestTime = Now() dbg_AllVars = false Set dbg_Data = Server.CreateObject("Scripting.Dictionary") DivSets(0) = "|" DivSets(1) = "|" DivSets(2) = "|" dbg_Show_default = "0,0,0,0,0,0,0,0,0,0,0" End Sub Public Property Let Enabled(bNewValue) ''''[bool] Sets "enabled" to true or false dbg_Enabled = bNewValue End Property Public Property Get Enabled ''''[bool] Gets the "enabled" value Enabled = dbg_Enabled End Property Public Property Let Show(bNewValue) ''''[string] Sets the debugging panel.
