Re: Valid regular expression not working with validator control

Tech-Archive recommends: Repair Windows Errors & Optimize Windows Performance

Hello Andrew,

Hi

thanks for the tip. I still can't get what I want to work. I'm using
Expresso to test.

Basically I want to make sure that if an input text includes a certain
domain then validation fails, e.g.

anyone@xxxxxxxxxxxxxxxxxxxxxx fails
anyone@xxxxxxxxxxxxxxxxxx succeeds
Please bear with me as I'm a complete novice with regular expressions.

^[^@]+@(?!not-allowed-domain.com$).*$

should do, though it doesn't check the syntax of the email address itself, it does exclude the domain you want.

Jesse



Thanks again
Andrew

Hello Andrew,

Hi

I get a JavaScript error with this expression when using the
RegExpValidator. Also if I switch off client script the server side
code validator finds a match regardless of the entered string.

(?<!@emailaddressnotallowed\.org)$

Is there a way of writing this so it works with the validator in
both client side and server side?

Look behinds are not supported in Client Side code. So you need to
rewrite this to either a full expression or to use a look ahead like
this:

^regexuptothe@(?!emailaddressnotallowed\.org$)restofthedomainregex$
