How to format a phone number with jQuery

Question

I\'m currently displaying phone numbers like 2124771000. However, I need the number to be formatted in a more human-readable form, for example: 212-477-10

Answer 1

An alternative solution:

function numberWithSpaces(value, pattern) {
  var i = 0,
    phone = value.toString();
  return pattern.replace(/#/g, _ => phone[i++]);
}

console.log(numberWithSpaces('2124771000', '###-###-####'));

Answer 2

I found this question while googling for a way to auto-format phone numbers via a jQuery plugin. The accepted answer was not ideal for my needs and a lot has happened in the 6 years since it was originally posted. I eventually found the solution and am documenting it here for posterity.

Problem

I would like my phone number html input field to auto-format (mask) the value as the user types.

Solution

Check out Cleave.js. It is a very powerful/flexible and easy way to solve this problem, and many other data masking issues.

Formatting a phone number is as easy as:

var cleave = new Cleave('.input-element', {
    phone: true,
    phoneRegionCode: 'US'
});

Answer 3

may be this will help

var countryCode = +91;
var phone=1234567890;
phone=phone.split('').reverse().join('');//0987654321
var formatPhone=phone.substring(0,4)+'-';//0987-
phone=phone.replace(phone.substring(0,4),'');//654321
while(phone.length>0){
formatPhone=formatPhone+phone.substring(0,3)+'-';
phone=phone.replace(phone.substring(0,3),'');
}
formatPhone=countryCode+formatPhone.split('').reverse().join('');

you will get +91-123-456-7890

Answer 4

Simple: http://jsfiddle.net/Xxk3F/3/

$('.phone').text(function(i, text) {
    return text.replace(/(\d{3})(\d{3})(\d{4})/, '$1-$2-$3');
});

Or: http://jsfiddle.net/Xxk3F/1/

$('.phone').text(function(i, text) {
    return text.replace(/(\d\d\d)(\d\d\d)(\d\d\d\d)/, '$1-$2-$3');
});

Note: The .text() method cannot be used on input elements. For input field text, use the .val() method.

Answer 5

Quick roll your own code:

Here is a solution modified from Cruz Nunez's solution above.

// Used to format phone number
function phoneFormatter() {
  $('.phone').on('input', function() {
    var number = $(this).val().replace(/[^\d]/g, '')
    if (number.length < 7) {
      number = number.replace(/(\d{0,3})(\d{0,3})/, "($1) $2");
    } else if (number.length <= 10) {
    number = number.replace(/(\d{3})(\d{3})(\d{1,4})/, "($1) $2-$3");
    } else {
    // ignore additional digits
    number = number.replace(/(\d{3})(\d{1,3})(\d{1,4})(\d.*)/, "($1) $2-$3");
    }
    $(this).val(number)
  });
};

$(phoneFormatter);

JSFiddle

• In this solution, the formatting is applied no matter how many digits the user has entered. (In Nunes' solution, the formatting is applied only when exactly 7 or 10 digits has been entered.)

• It requires the zip code for a 10-digit US phone number to be entered.

• Both solutions, however, editing already entered digits is problematic, as typed digits always get added to the end.

• I recommend, instead, the robust jQuery Mask Plugin code, mentioned below:

Recommend jQuery Mask Plugin

I recommend using jQuery Mask Plugin (page has live examples), on github.

WordPress Contact Form 7: use Masks Form Fields plugin

If you are using Contact Form 7 plugin on a WordPress site, the easiest option to control form fields is if you can simply add a class to your input field to take care of it for you.
Masks Form Fields plugin is one option that makes this easy to do.
I like this option, as, Internally, it embeds a minimized version of the code from jQuery Mask Plugin mentioned above.

Example usage on a Contact Form 7 form:

<label> Your Phone Number (required)
    [tel* customer-phone class:phone_us minlength:14 placeholder "(555) 555-5555"]
</label>

The important part here is class:phone_us.
Note that if you use minlength/maxlength, the length must include the mask characters, in addition to the digits.

Answer 6

Don't forget to ensure you are working with purely integers.

var separator = '-';
$( ".phone" ).text( function( i, DATA ) {
    DATA
        .replace( /[^\d]/g, '' )
        .replace( /(\d{3})(\d{3})(\d{4})/, '$1' + separator + '$2' + separator + '$3' );
    return DATA;
});
