One regex used anchors while the other did not, without explanation. Edited for consistency and explanation

@Timo [^\s@] means "neither a whitespace character nor @". [xyz] means any one of x, y or z, and [^xyz] means any one character except x, y or z. \s means "any whitespace character". \S means "any character that is not whitespace".

2 issues: Is [^\s@] no string followed by @? Why do you use \s and \S? Is it related to whitespaces?

@JoseG. Yes. E.g. http://ai is someone's valid domain, so they could use e.g. a@ai as their email.

Emails can contain multiple @ signs (as comments), also an email doesn't have to contain a period.

The second regexp does not require a top-level domain, i.e. it accepts user@domain. But AFAIK this is actually a valid e-mail address, although uncommon. The first regexp requires a TLD, so it doesn't cover these types of addresses.

@ImmortalFirefly, the regex you provided will actually match name@[email protected]. Try pasting your line into a JavaScript console. I believe your intention was to match only the entire text, which would require the beginning of text '^' and end of text '$' operators. The one I'm using is /^[^\s@]+@[^\s@]+\.[^\s@]+$/.test('name@[email protected]')

| Jul 30, 2012 at 18:20 | comment | added | user83358 | You can implement something 20x as long that might cause problems for a few users and might not be valid in the future, or you can grab ImmortalFirefly's version to make sure they at least put in the effort to make it look real. Depending on your application it may be more likely to come across someone will get mad because you don't accept their unconventional email, rather than someone who causes problems by entering email addresses that don't really exist (which they can do anyways by entering a 100% valid RFC2822 email address but using an unregistered username or domain).
