    </form>

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??

What do you mean by validate? JavaScipt can only test if the email address is correctly formatted - not whether the email address is in use or not. — , May 13 '14 at 06:24
@jeff am asking the same how to test whether the if the email address is correctly formatted. — User2413, May 13 '14 at 06:27

(\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)

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!

String literals make use of the backslash as the start of an escape sequence. If you want the actual backslash character to be part of the regex you're building, then you need to escape it in the string so that the actual character appears in the resulting string. – cookie monster May 13 '14 at 06:29
For example: `new RegExp("^\\w+@\\w+\\.("+str+")$")` – cookie monster May 13 '14 at 06:35
@aelor I suppose you meant `str.join("|")` and not `str` ? – Gaurang Tandon May 13 '14 at 06:40
@GaurangTandon WE JOIN ARRAYS, NOT STRINGS – aelor May 13 '14 at 07:22
@aelor Oh, ok, I did not see that `str` actually had as a value `arr.join("|")`. No need to shout for that I suppose. – Gaurang Tandon May 13 '14 at 11:30

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 .
