is_email() is a function to validate an email address against relevant RFCs
Note:- It doesn't not support DNS check for MX records and parsed address components like the PHP is_email does.
- Include is_email.js in your page.
- And start validating emails.
var check = is_email"firstname.lastname@example.org";if checkalert"You have entered correct email address.";elsealert"Please provide correct email address.";
