Input IBAN

lion-input-iban component is based on the generic text input field. Its purpose is to provide a way for users to fill in an IBAN (International Bank Account Number).

import { html } from 'lit-html';
import { loadDefaultFeedbackMessages } from '@lion/validate-messages';
import { IsCountryIBAN } from './src/validators.js';

import './lion-input-iban.js';

export default {
  title: 'Forms/Input Iban',
};

loadDefaultFeedbackMessages();

export const main = () => {
  return html` <lion-input-iban label="Account" name="account"></lion-input-iban> `;
};

How to use

Installation

npm i --save @lion/input-amount

import { LionInputIban } from '@lion/input-iban';
// or
import '@lion/input-amount/lion-input-amount.js';

Examples

Prefilled

export const prefilled = () => html`
  <lion-input-iban .modelValue=${'NL20INGB0001234567'} name="iban" label="IBAN"></lion-input-iban>
`;

Faulty Prefilled

export const faultyPrefilled = () => html`
  <lion-input-iban
    .modelValue=${'NL20INGB0001234567XXXX'}
    name="iban"
    label="IBAN"
  ></lion-input-iban>
`;

Country Restrictions

By default, we validate the input to ensure the IBAN is valid. To get the default feedback message for this default validator, use loadDefaultFeedbackMessages from @lion/form-core.

In the example below, we show how to use an additional validator that restricts the input-iban to IBANs from only certain countries.

export const countryRestrictions = () => html`
  <lion-input-iban
    .modelValue=${'DE89370400440532013000'}
    .validators=${[new IsCountryIBAN('NL')]}
    name="iban"
    label="IBAN"
  ></lion-input-iban>
