Are you nuts? That's just the sort of thing Regexp was designed
to do.
And, it's not really all that complex.
Yes it is. The *only* correct regexps I am aware of for e-mail
addresses are on the order of a page in length. All shorter
regexps
reject some valid e-mail addresses.
Thanks Marnen. I stand corrected.
However, just to clarify, are you saying that Regexp is still the
best
approach? Given that what you're saying is true, which I'm sure it
is,
then I could imagine that performing this validation without using
Regexp would be even more complex and require quite a bit more code.
The best approach is to download a plugin for email validation,
because
someone, somewhere, has already done all the work ;-)
I wouldn't trust those plugins without inspecting their algorithms. I
would probably use something like the following regex:
/^...@.+\..+$/
This checks that it's of the form "[email protected]", but
performs no further validation.
Good point. It annoys me to no end when I can't enter [email protected]
as a valid email address. Seems this works about half the time.
The bottom line is if you are really concerned about getting a valid
email address, the only way to completely verify it is to send them an
email and make them confirm it via a link in that email. Headache,
yeah, but it works.
