format int to phone number

问题

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);

Edit

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

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

回答1:

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:

http://jsfiddle.net/HZbXv/

var str = "0000000000";

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

alert(res);

or this:

http://jsfiddle.net/HZbXv/1/

var str = "0000000000";

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

alert(res);

EDIT:

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');

As simple as this. Can use a simple if statement if you are going to deal with multiple numbers.

    YourVariable = YourVariable.replace(/(\d{1})(\d{3})(\d{3})(\d{4})/, "+$1 ($2)-$3-$4"); 

Displays: +1 (800)-555-5555

    YourVariable = YourVariable.replace(/(\d{3})(\d{3})(\d{4})/, "($1)-$2-$3"); 

Displays (555)-555-5555

If statement (my own code):

if (form.FaxNumber.length = 11){
    form.FaxNumber.value = form.FaxNumber.value.replace(/(\d{1})(\d{3})(\d{3})(\d{4})/, "+$1 ($2)-$3-$4");
}
if (form.FaxNumber.length = 10){
    form.FaxNumber.value = form.FaxNumber.value.replace(/(\d{3})(\d{3})(\d{4})/, "($1)-$2-$3");
}
