VBS中的正则表达式的用法大全

VBS正则表达式函数
主要用在asp中效果明显
1、表单验证功能

CODE代码:[复制此代码]
Function Validate(strng,patrn)
Dim regEx
Set regEx = New RegExp
regEx.Pattern = patrn
regEx.IgnoreCase = True
regEx.Global = True
Validate = regEx.test(strng)
Set regEx = Nothing
End Function
使用例子
If Validate(Fdr.Name,"F\d{4}_P\d{4}")=True Then
... ...
End If

HTML代码:<input name=jb51 value="13003523068">
<button onclick=checkit(jb51.value)>测试</button>
<script language=vbscript>
function check(str)
dim re
set re=new regexp
re.global=true
re.ignorecase=true
re.pattern="1[3|5]\d{9}"
check=re.test(str)
set re=nothing
end function

sub checkit(str)
if check(str)=true then
msgbox "是手机"
else
msgbox "不是手机"
end if
end sub
</script>
