Usage

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

1. Type

There are three types of payment data iFields supports:

• Credit Card
• CVV
• ACH

    <IField type={CARD_TYPE} />

The possible values for this property are

• card
• cvv
• ach

These can be imported from the component

import { CARD_TYPE, CVV_TYPE, ACH_TYPE } from '@cardknox/react-ifields';

2. Account

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

export default class App extends React.Component {
  state = {
    account = {
      xKey: "{Your iFields key}",
      xSoftwareName: "{The name of your app}",
      xSoftwareVersion: "{Your app's version}"
    }
  }
  render() {
    return <IField account={this.state.account} />
  }
}

---

Events

There are 2 lifecycle events and 7 user events.

---

Lifecycle events

1. Load

Is emitted when the iframe has loaded

    <IField onLoad={this.onLoad} />

2. Token

Is emitted when a token is received from the iField

    <IField onToken={this.onToken} />

---

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. keypress
8. issuerupdated (CVV only)
9. submit*

* the submit event works slightly differently, see below.

Update Event

Aside from submit, the above events are all collected on a single event update.

The event payload is in e.data. The data also contains the event type so you can filter out events you don't need with a switch statement like this:

export default class App extends React.Component {
  render() {
    return <IField onUpdate={this.onUpdate} />
  }
  onUpdate = (data) => {
    switch (data.event) {
      case 'input':
        console.log("input event received");
        break;
      case 'click':
        console.log("click event received");
        break;
      default:
        break;
    }
  }
}

Submit Event

This event is triggered when the user submits the form (presses the Enter key) from within the iFrame.

This event works differently than other user events.

• This event is only emitted if prop options.autoSubmit is true.
• This event does not call onUpdate.
• No data is passed along with this event.

export default class App extends React.Component {
  state = {
    options: {
      autoSubmit: true
    }
  }
  render() {
    return <IField options={this.state.options} onSubmit={this.onSubmit} />
  }
  onSubmit = () => {
    //submit to server
  }
}

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.

export default class App extends React.Component {
  state = {
    options: {
      autoSubmit: true,
      autoSubmitFormId: 'form'
    }
  }
  render() {
    return <form id="form">
        <IField options={this.state.options} />
      </form>
  }
}

Error

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

export default class App extends React.Component {
  render() {
    return <IField onError={this.onError} />
  }
  onError = (data) => {
    console.error("IFrame errored", data);
  }
}

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.

export default class App extends React.Component {
  iFieldRef = React.createRef();
  render() {
    return <IField ref={this.iFieldRef} />
  }
  focus = () => {
    this.iFieldRef.current.focusIfield();
  }
  clear = () => {
    this.iFieldRef.current.clearIfield();
  }
  getToken = () => {
    this.iFieldRef.current.getToken();
  }
}
