Validating email format javascript

RFC 2822 and the related specs are really quite permissive in terms of email addresses, so a class like this is overkill for most uses. Only way to build yourself (but this is a snapshot, not RELEASE) and use, or download from here.

For example, the following is a legitimate address, according to spec, spaces and all: No mail server would allow that, but this class can parse it (and rewrite it to a usable form). This means 1.4 has not been made final for three years (2008-2011). I'm looking for a better option, but didn't find one that is very adopted.

BTW, I found that there is a 1.4 version, here are the API docs.

Form validation normally used to occur at the server, after the client had entered all the necessary data and then pressed the Submit button.
