Ideally, you would have this function run during the on Submit attribute for the form tag.

This way, the form will get submitted when the check Email() function returns a true value.

I have borrowed the regex for verifying the correct email format from a different site. Please note that I have removed the action attribute because this is only a demo and we are only concerned with the client-side verification of the Java Script function.

Nothing exciting here except in line 6 where the on Click event is triggered when the user clicks on the button.

If we have passed the two tests, then else block in lines 11-14 gets executed.

An alert tells the user that he or she has done a good job and the function returns a true value so that you can continue with the form submission.

The result of sending an email to a badly formatted email address would be the same: it’ll get bounced. If you really want to do checking of email addresses right on the signup page, include a confirmation field so they have to type it twice.

If your user enters a bad email address, they won’t get the activation email and they’ll try to register again if they really care about using your site. Enterprising individuals will just copy and paste, but what it comes down to is this: if your user enters a bad email address, you shouldn’t make it more of a problem for yourself than you have to.

Here’s a fairly common code sample from Rails Applications with some sort of authentication system: If you’re experienced at Regex, this seems simple. Sections 3.2.4 and 3.4.1 of the RFC go into the requirements on how an email address needs to be formatted and, well, there’s not much you can’t do in your email address when quotes or backslashes are involved.

If (like me when I first saw this) you AREN’T experienced at Regex, it takes a while to parse. The local string (the part of the email address that comes before the @) can contain any of these characters: is a valid email address. For this reason, for a time I began running any email address against the following regular expression instead: Simple, right? This is often the most I do and, when paired with a confirmation field for the email address on your registration form, can alleviate most problems with user error.

If the search() method returns a -1, then an alert would tell the user that an invalid email address has been entered and returns a false value.

Lines 7-10 checks to see if the user has entered the same string in both email fields.
