Validating email in javascript

The following example shows how you can validate an email address for a form.

This javascript validation code is cross browser compatible (works for all browsers).

To fix this problem, you implement an activation system where, after registering, I am sent an email with a link I must click.

This is to verify that I actually own that email address before my account is activated.

Do you need to validate or verify an email address?

Now we will see how we can validate our entered form data before submitting it to the web server. If you actually check the Google query I linked above, people have been writing (or trying to write) RFC-compliant regular expressions to parse email addresses for years.But what if I told you there were a way to determine whether or not an email is valid without resorting to regular expressions at all? The activation email is a practice that’s been in use for years, but it’s often paired with complex validations that the email is formatted correctly.(For more information on how to create form validation using the Front Page form feature, see About creating forms in Front Page 2003.) However, if the form validation provided in Front Page does not suit your needs or the site on which you are working is hosted on a server that does not have Front Page Server Extensions from Microsoft installed, you may need to create custom form validation.Note Front Page Server Extensions are a set of programs that provide access to special Front Page features, such as database processing, form processing, hit counters, and other built-in Front Page components that require server-side processing.At this point, why keep parsing email addresses for their format?
