Angular iFields

Cardknox offers an Angular component for iFrame fields to send card information directly to the Cardknox system for in-store, online, or mobile transactions

Sandbox: https://www.cardknox.com/sandbox/

iFields: https://www.cardknox.com/ifields/

A sandbox or live account is required to use this component.

Inputs

There are 2 basic inputs required to get this up and running.

1. Type

There are three types of payment data iFields supports:

  • Credit Card

  • CVV

  • ACH

<cardknox-ifields [type]="CARD"></cardknox-ifields>

The possible values for this property are

  • card

  • cvv

  • ach

These can be imported from the component

import { ACH_TYPE, CARD_TYPE, CVV_TYPE, AngularIfieldsComponent } from '@cardknox/angular-ifields';
/**...*/
CARD = CARD_TYPE;

2. Account

Pass your iFields key to the component in the account input like this:

<cardknox-ifields [account]="account"></cardknox-ifields>
/**...*/
account = {
xKey: '{Your iFields key}',
xSoftwareName: '{The name of your app}',
xSoftwareVersion: '{Your app's version}'
}

Events

There are 2 lifecycle events and 7 user events.

Lifecycle events

1. Load

Is emitted when the iframe has loaded

1 <cardknox-ifields (load)="onLoad"></cardknox-ifields>

2. Token

Is emitted when a token is received from the iField

1 <cardknox-ifields (token)="onToken"></cardknox-ifields>

User events

User events are events passed along from iFields when the user interacts with it.

The available events are

  1. click

  2. dblclick

  3. focus

  4. blur

  5. input

  6. change

  7. submit*

  • the submit event works slightly differently, see below.

Update

Aside from submit, the above events can be collected on a single event update. This is not recommended as it will cause an unnecessary amount of function calls. Instead subscribe only to the events you want to act on.

The event payload is in e.data. The data also contains the event so you can subscribe to multiple events with a single function and a switch statement like this:

<cardknox-ifields (update)="onUpdate($event)"></cardknox-ifields>
/**...*/
onUpdate({ data }) {
switch (data.event) {
case 'input':
console.log("input event received");
break;
case 'click':
console.log("click event received");
break;
}
}

Submit

This event is triggered when the user submits the form from within the iFrame.

This event works differently than other user events.

  • This event is only emitted if prop options.autoSubmit is true. (This is the default.)

  • Subscribing to update will not work as mentioned above.

  • The data passed along with this event is slightly different, (see below).

<form id="form">
<cardknox-ifields [options]="options"></cardknox-ifields>
</form>
/**...*/
options = {
autoSubmit: true,
autoSubmitFormId: 'form'
}

It is also possible to have the component automatically submit the form for you when submit is triggered from the iFrame. If autoSubmitFormId is set on the options prop the component will call submit on the element with that ID. This is useful for smaller applications relying on the form element to handle submission.

<form id="form">
<cardknox-ifields [options]="options"></cardknox-ifields>
</form>
/**...*/
options = {
autoSubmit: true,
autoSubmitFormId: 'form'
}

Error

There is also an error event that can be subscribed to.

Actions

There are 3 actions available on this component as well

Focus

focusIfield

This action will set the focus to the ifield when called

Clear

clearIfield

This action will clear the data from the ifield when called

Get Token

getToken

This action will load the token for the ifield when called.

<cardknox-ifields #card></cardknox-ifields>
@ViewChild('card') cardIfield?: AngularIfieldsComponent;
this.cardIfield.focusIfield();
this.cardIfield.clearIfield();
this.cardIfield.getToken();
