Email validation using regular expression in jQuery

-
To validate user input for email-id it's very easy using regular expressions. Using regular expressions you do not need to write lengthy logical code in jQuery. Following are the steps to do the same.

  • Pass a string to RegExp or create a regex using the //syntax
  • Call regex.test(string)
So code would be...
jQuery(function () {
    $(".mail").keyup(function () {
        var VAL = this.value;

        var email = new RegExp('^[A-Z0-9._%+-]+@[A-Z0-9.-]+\.[A-Z]{2,4}$');

        if (email.test(VAL)) {
            alert('Great, you entered an valid E-Mail-address');
        }
    });
});
