Pattern matching in jQuery?

I have strings(phone numbers) like this:

1112223333
1234567890

And I want to convert these lik开发者_Python百科e this:

(111)222-3333
(123)456-7890

How to do this is jQuery.

Thanks

var phone = '1234567890';

phone.replace(/^(\d{3})(\d{3})(\d+)$/, '($1)$2-$3'); // (123)456-7890

See it on jsFiddle.

If you want to match that length exactly, use a {4} quantifier in place of the last +.

No jquery needed, just javascript regular expressions:

var aNumber = '1112223333';
var aPhoneNumber = aNumber.replace(/^(\d{3})(\d{3})(\d{4})$/, '($1)$2-$3');

By the way, I'm assuming numbers are always of the form '(xxx)xxx-xxxx', 3-3-4 numbers.
