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

Consider libphonenumber-js (https://github.com/halt-hammerzeit/libphonenumber-js) which is a smaller version of the full and famous libphonenumber.

Quick and dirty example:

$(".phone-format").keyup(function() {
// Don't reformat backspace/delete so correcting mistakes is easier
if (event.keyCode != 46 && event.keyCode != 8) {
    var val_old = $(this).val();
    var newString = new libphonenumber.asYouType('US').input(val_old);
    $(this).focus().val('').val(newString);
}
});

(If you do use a regex to avoid a library download, avoid reformat on backspace/delete will make it easier to correct typos.)

Answer 2

I have provided jsfiddle link for you to format US phone numbers as (XXX) XXX-XXX

 $('.class-name').on('keypress', function(e) {
  var key = e.charCode || e.keyCode || 0;
  var phone = $(this);
  if (phone.val().length === 0) {
    phone.val(phone.val() + '(');
  }
  // Auto-format- do not expose the mask as the user begins to type
  if (key !== 8 && key !== 9) {
    if (phone.val().length === 4) {
      phone.val(phone.val() + ')');
    }
    if (phone.val().length === 5) {
      phone.val(phone.val() + ' ');
    }
    if (phone.val().length === 9) {
      phone.val(phone.val() + '-');
    }
    if (phone.val().length >= 14) {
      phone.val(phone.val().slice(0, 13));
    }
  }

  // Allow numeric (and tab, backspace, delete) keys only
  return (key == 8 ||
    key == 9 ||
    key == 46 ||
    (key >= 48 && key <= 57) ||
    (key >= 96 && key <= 105));
})

.on('focus', function() {
  phone = $(this);

  if (phone.val().length === 0) {
    phone.val('(');
  } else {
    var val = phone.val();
    phone.val('').val(val); // Ensure cursor remains at the end
  }
})

.on('blur', function() {
  $phone = $(this);

  if ($phone.val() === '(') {
    $phone.val('');
  }
});

Answer 3

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

Output :-(123) 657-8963

Answer 4

Here's a combination of some of these answers. This can be used for input fields. Deals with phone numbers that are 7 and 10 digits long.

// 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{3})(\d{4})/, "$1-$2");
    } else if (number.length == 10) {
      number = number.replace(/(\d{3})(\d{3})(\d{4})/, "($1) $2-$3");
    }
    $(this).val(number)
  });
}
