format int to phone number

Is there a way I can format for example: 0000000000 into (000)000-0000? I'm returning a listbox which holds a collection of phone number which arent formated yet. What I would like is format it. This is what I have in the View:

<%= Html.ListBox("phoneList")%>

and from the controller:

ViewData["phoneList"] = new SelectList(phoneList);


$('#phoneList').each(function() {
var phoneNumber = $(this).text();
var formatPhoneNumber = phoneNumber.replace(/(\d{3})(\d{3})(\d{4})/, '($1)$2-$3');

how would I assign this back to show in the ListBox?

If you're saying that you want to do it on the client side, then given the phone number in a variable, you could do this:


var str = "0000000000";

var res = '(' + str.substr(0,3) + ')' + str.substr(3,3) + '-' + str.substr(6);


or this:


var str = "0000000000";

var res = str.replace(/(\d\d\d)(\d\d\d)(\d\d\d\d)/, '($1)$2-$3');



As noted by @Nick Craver The second version can be shortened up with:

var res = str.replace(/(\d{3})(\d{3})(\d{4})/, '($1)$2-$3');
