比如 1223445677777778aabbcccccccccc 经过过滤之后就是12345678abc
复制代码 代码如下:
<%
'过滤重复
Function norepeat(Str)
Dim RegEx
If IsNull(Str) Or Str="" Then Exit Function
Set RegEx=New RegExp
RegEx.Global = True
RegEx.IgnoreCase=True
RegEx.MultiLine = True
RegEx.pattern="(.)1+"
str=regEx.replace(str,"$1")
Set RegEx=Nothing
Norepeat=str
End Function
'示例
s="1223445677777778aabbcccccccccc"
response.write Norepeat(s)
%>
