Validate Email
In order to validate email, you can use the regular expression and test() method.
var a = "test@gmail.com";
var b = "test.example.com";
var c = "A@b@c@example.com";
function validateEmail(email) {
// Regular expression for email search pattern
var re = /^[^\s@]+@[^\s@]+$/;
// If email's pattern is found in variable re
if (re.test(email)) {
// Display valid email message
console.log(email + " is a valid email address");
}
// Else if email's pattern cannot be found in variable re
else {
// Display invalid email message
console.log(email + " is an invalid email address");
}
}
validateEmail(a);
// => "test@gmail.com is a valid email address"
validateEmail(b);
// => "test.example.com is an invalid email address"
validateEmail(c);
// => "A@b@c@example.com is an invalid email address"
Note: The regular expression is a sequence of characters used as a search pattern. The test() method functions by testing for a match in the supplied string.
