Recently some friends who have just learned regular expressions ask me how to use in ASP. Oh Although it is simple, write it, the basic knowledge of regular expressions I will not say. In fact, there are many such articles. ：（

##### function Code ########
assumed to be myfunc.asp

<%
' Regular table expression validation function patrn-Regular expression strng-a string to be validated
Function regexptest (PATRN, STRNG)
Dim regEx, RetVal ' Set variable.
Set regEx = New RegExp ' establishes a regular expression.
Regex.pattern = Patrn ' Set mode.
Regex.ignorecase = False ' Sets whether case sensitive.
RetVal = regex.test (strng) ' performs a search test.
Regexptest = RetVal ' Returns the value, does not conform returns false, conforms to true
End Function
%>

##### Submit page Code ######
assumed to be mypage.asp

<form method= "POST" action= "check.asp" >
Please enter e-mail address: <input type=text name=email>
<br>
Please enter the phone number: <input type=text name=tel>
<input type=submit value= "OK" >
</form>

##### Validation Page ########
assumed to be check.asp

<!--#include file= "myfunc.asp"-->
<%
Tel=request.form ("tel")
Email=request.form ("email")
Dim founderr:founderr=false ' Create variable, correct or fail tag
' Everybody, by the way, I'm here to contribute a regular expression and verify the phone number and phone number!
If Regexptest ("(^[0-9]{3,4}\-[0-9]{3,8}$) | ( ^[0-9]{3,8}$) | (^\ ([0-9]{3,4}\) [0-9]{3,8}$) | (^0{0,1}13[0-9]{9}$) ", tel) =false Then
Founderr=true
regshow=regshow& "<li> The phone number you entered is not in the correct format"
End If
If Regexptest ("^[\w-]+" (\.[ \w-]+) *@[\w-]+ (\.[ \w-]+) +$ ", email) =false Then
Founderr=true
regshow=regshow& "<li> e-mail you entered is not in the correct format"
End If
If Founderr=false then regshow= "<li> the format you entered is correct."
