HostedFields

Example

hostedFieldsInstance.addClass('number', 'custom-class', function (addClassErr) {
  if (addClassErr) {
    console.error(addClassErr);
  }
});

Examples

hostedFieldsInstance.clear('number', function (clearErr) {
  if (clearErr) {
    console.error(clearErr);
  }
});

Clear several fields

hostedFieldsInstance.clear('number');
hostedFieldsInstance.clear('cvv');
hostedFieldsInstance.clear('expirationDate');

Examples

hostedFieldsInstance.focus('number', function (focusErr) {
  if (focusErr) {
    console.error(focusErr);
  }
});

Using an event listener

myElement.addEventListener('click', function (e) {
  // In Firefox, the focus method can be suppressed
  //   if the element has a tabindex property or the element
  //   is an anchor link with an href property.
  e.preventDefault();
  hostedFieldsInstance.focus('number');
});

Example

hostedFieldsInstance.getChallenges().then(function (challenges) {
  challenges // ['cvv', 'postal_code']
});

Example

Check if all fields are valid

var state = hostedFieldsInstance.getState();

var formValid = Object.keys(state.fields).every(function (key) {
  return state.fields[key].isValid;
});

Example

hostedFieldsInstance.getSupportedCardTypes().then(function (cardTypes) {
  cardTypes // ['Visa', 'American Express', 'Mastercard']
});

Example

Subscribing and then unsubscribing from a Hosted Field event, in this case 'focus'

hostedFields.create({ ... }, function (createErr, hostedFieldsInstance) {
  var callback = function (event) {
    console.log(event.emittedBy, 'has been focused');
  };
  hostedFieldsInstance.on('focus', callback);

  // later on
  hostedFieldsInstance.off('focus', callback);
});

Example

Listening to a Hosted Field event, in this case 'focus'

hostedFields.create({ ... }, function (createErr, hostedFieldsInstance) {
  hostedFieldsInstance.on('focus', function (event) {
    console.log(event.emittedBy, 'has been focused');
  });
});

Example

Remove the placeholder attribute of a field

hostedFieldsInstance.removeAttribute({
  field: 'number',
  attribute: 'placeholder'
}, function (attributeErr) {
  if (attributeErr) {
    console.error(attributeErr);
  }
});

Example

hostedFieldsInstance.addClass('number', 'custom-class', function (addClassErr) {
  if (addClassErr) {
    console.error(addClassErr);
    return;
  }

  // some time later...
  hostedFieldsInstance.removeClass('number', 'custom-class');
});

Examples

Set the placeholder attribute of a field

hostedFieldsInstance.setAttribute({
  field: 'number',
  attribute: 'placeholder',
  value: '1111 1111 1111 1111'
}, function (attributeErr) {
  if (attributeErr) {
    console.error(attributeErr);
  }
});

Set the aria-required attribute of a field

hostedFieldsInstance.setAttribute({
  field: 'number',
  attribute: 'aria-required',

  if (tokenizeErr) {
    switch (tokenizeErr.code) {
      case 'HOSTED_FIELDS_FIELDS_EMPTY':
        // occurs when none of the fields are filled in
        console.error('All fields are empty! Please fill out the form.');
        break;
      case 'HOSTED_FIELDS_FIELDS_INVALID':
        // occurs when certain fields do not pass client side validation
        console.error('Some fields are invalid:', tokenizeErr.details.invalidFieldKeys);

        // you can also programmatically access the field containers for the invalid fields
        tokenizeErr.details.invalidFields.forEach(function (fieldContainer) {
          fieldContainer.className = 'invalid';
        });
        break;
      case 'HOSTED_FIELDS_TOKENIZATION_FAIL_ON_DUPLICATE':
        // occurs when:

    firstName: 'First',
    lastName: 'Last',
    company: 'Company',
    streetAddress: '123 Street',
    extendedAddress: 'Unit 1',
    // passing just one of the country options is sufficient to
    // associate the card details with a particular country
    // valid country names and codes can be found here:

Allow tokenization with empty cardholder name field

var state = hostedFieldsInstance.getState();
var fields = Object.keys(state.fields);

// normally, if you tried to tokenize an empty cardholder name field
// you would get an error, to allow making this field optional,
// tokenize all the fields except for the cardholder name field
// when the cardholder name field is empty. Otherwise, tokenize
// all the fields
if (state.fields.cardholderName.isEmpty) {
 fields = fields.filter(function (field) {
   return field !== 'cardholderName';
 });
}

hostedFieldsInstance.tokenize({
 fieldsToTokenize: fields
}, function (tokenizeErr, payload) {
  if (tokenizeErr) {
    console.error(tokenizeErr);
  } else {
    console.log('Got nonce:', payload.nonce);
  }
});

hostedFields.create({ ... }, function (createErr, hostedFieldsInstance) {
  hostedFieldsInstance.on('inputSubmitRequest', function () {

hostedFields.create({ ... }, function (createErr, hostedFieldsInstance) {
  hostedFieldsInstance.on('validityChange', function (event) {
    var field = event.fields[event.emittedBy];

    if (field.isValid) {
      console.log(event.emittedBy, 'is fully valid');
    } else if (field.isPotentiallyValid) {
      console.log(event.emittedBy, 'is potentially valid');
    } else {
