Answer №1

(\w+\.)*\w+@(\w+\.)+[A-Za-z]+

This regular expression validates email addresses in a simple way.

For this specific case, you can use the following regular expression:

((\w+\.)*\w+)@(\w+\.)+(com|kr|net|us|info|biz)

Alright, it's time to gather all the checked items' values and store them in an array (this should be within your capabilities by now)

Let's say the array is ["com","net"]

var arr = ["com","net"];
var str = arr.join("|")
var re = new RegExp("^\w+@\w+\.("+str+")$");
console.log(re);

The regular expression I've used here is quite basic, but you can customize it as per your requirements. Another answer on SO recommends using

"^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$"

for a more comprehensive email validator. So you could modify your second last line like this:

var re = new RegExp("^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.("+str+")$");

With this code, you'll have the regex necessary to validate your emails.

Now you can easily use the regex test to check which emails pass your validation criteria.

Happy coding!
