i want to validate email-ids with the extension which are checked in the above image and block rest of the email-id extensions using javascript..any help would be appreciated??

Answer 1

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

this regex is email check basic.

you may use regex for this case, follow regex:

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

Answer 2

okay , get all the values of checked items in an array (at least this much you should have been able to do by now)

now let the array be ["com","net"]

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

the regex I have used is the most basic of all, you can change it according to your needs. Another answer on SO suggests "^[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.[a-zA-Z0-9-.]+$" to be a more complete email validator. So you can change your second last line to :

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

this code will give you the regex you need to validate your email.

Now you can simply do regex test to see which emails pass your validation.

happy coding!

Answer 3

You can also use above regex ( aelor's )as

[a-zA-Z0-9_.+-]+@[a-zA-Z0-9-]+\.(COM|ORG|BIZ|CO)  

include your all extentions using pipe separator .
