GetBody asp实现截取字符串的代码
'================================================== '函数名：GetBody '作 用：截取字符串 '参 数：ConStr ------将要截取的字符串 '参 数：StartStr ------开始字符串 '参 数：OverStr ------结束字符串 '参 数：IncluL ------是否包含StartStr '参 数：IncluR ------是否包含OverStr '================================================== Function GetBody(ConStr,StartStr,OverStr,IncluL,IncluR) If ConStr="$False$" or ConStr="" or IsNull(ConStr)=True Or StartStr="" or IsNull(StartStr)=True Or OverStr="" or IsNull(OverStr)=True Then GetBody="$False$" Exit Function End If Dim ConStrTemp Dim Start,Over ConStrTemp=Lcase(ConStr) StartStr=Lcase(StartStr) OverStr=Lcase(OverStr) Start = InStrB(1, ConStrTemp, StartStr, vbBinaryCompare) If Start<=0 then GetBody="$False$" Exit Function Else If IncluL=False Then Start=Start+LenB(StartStr) End If End If Over=InStrB(Start,ConStrTemp,OverStr,vbBinaryCompare) If Over<=0 Or Over<=Start then GetBody="$False$" Exit Function Else If IncluR=True Then Over=Over+LenB(OverStr) End If End If GetBody=MidB(ConStr,Start,Over-Start) End Function
