RE: email regex?
Here's one I use at work:
function validateEmail(vfld,displayName) {
var tfld = trim(vfld.value); // value of field with whitespace
trimmed off
var email = /[EMAIL PROTECTED]@[EMAIL PROTECTED]@]*\w\w$/
if (!email.test(tfld)) {
alertUser(ERROR: + displayname + is not a valid
email address.);
setfocus(vfld);
return false;
}
return true;
}

Re: email regex?
I don't generally bother, because you can validate the hell out of it, but [EMAIL PROTECTED] will always work :) I just don't think it's worth the effort to validate. If you want to ensure that it's a 'good' address, automatically send them an e-mail to which they must respond...or i think there are some web services out there now that will ping a mail server to see if the email address exists.

Yea, we're gonna do both, just trying to validate it a little bit before it makes it to the processing page. I just checked the livedocs and used that one.

Email Regex with weird results
All:
I've been using a regex found on this list to validate email addresses.
I've now run into a problem with the regex that I can't solve.Any help
would be greatly appreciated.
The email address is not required so the field can either be left blank or
must contain a valid email address.The regex validation code follows:
CFIF (Len(Trim(FORM.Email)) NEQ 0) AND
(REFindNoCase(^[a-zA-Z]([[:alnum:]\-_]+\.?)*@([[:alnum:]\-_]+\.)+[a-zA-Z]{2
,4}$, FORM.Email) EQ 0)
Email address is invalid
/CFIF
The email address is of the form [EMAIL PROTECTED] (that is, the domain
contains a dash).If I remove the dash from the domain, the address
validates.However, the dash should be valid.
Looking at the regex, doesn't the ([[:alnum:]\-_]+\.) portion after the @
symbol allow for dashes?
TIA

Re: Email Regex with weird results
The - needs to be the very last character in the class.
This is because the - in any other postion indicates a range of chars.
so \-_ is saying\]^_ (which is the \ character to the _ character in the ascii table)

RE: Email Regex with weird results
I think you just need to modify the domain check a little bit...
[[:alnum:]\-_]
Should be
[[:alnum:]_-]
Otherwise you're matching everything between '\' and '_'. The ASCII sequence
this matches is \[^_
Presumably you want to allow only alpha numeric, _ and - in the domain name.
