過(guò)程名:catch(str)
使用方法:
復(fù)制代碼 代碼如下:
on error resume next
'你的代碼,如數(shù)據(jù)庫(kù)連接
call catch("顯示給用戶(hù)的提示信息")
功能:清除IIS的錯(cuò)誤提示信息,自定義錯(cuò)誤提示返回給用戶(hù),并將出錯(cuò)信息保存到txt文件(當(dāng)然你也可以稍做修改轉(zhuǎn)向自定義頁(yè)面等)
代碼:
復(fù)制代碼 代碼如下:
%
option explicit
'例一---------------------------
'必須和on error resume next一起使用,但在網(wǎng)頁(yè)沒(méi)有正式發(fā)布之前最好將其注釋掉,以免在調(diào)試時(shí)看不到出錯(cuò)詳細(xì)信息
on error resume next
