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

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('');
  }
});
