```js script
|
|
import { html } from '@lion/core';
|
|
import { loadDefaultFeedbackMessages } from '@lion/validate-messages';
|
|
import { IsCountryIBAN, IsNotCountryIBAN } from '@lion/input-iban';
|
|
import '@lion/input-iban/define';
|
|
```
|

|
|
## Prefilled
|
|
|
|
```js preview-story
|
|
export const prefilled = () => html`
|
|
<lion-input-iban .modelValue=${'NL20INGB0001234567'} name="iban" label="IBAN"></lion-input-iban>
|
|
`;
|
|
```
|
|
|
|
## Faulty Prefilled
|
|
|
|
```js preview-story
|
|
export const faultyPrefilled = () => html`
|
|
<lion-input-iban
|
|
.modelValue=${'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.
|
|
|
|
```js preview-story
|
|
export const countryRestrictions = () => {
|
|
loadDefaultFeedbackMessages();
|
|
return html`
|
|
<lion-input-iban
|
|
.modelValue=${'DE89370400440532013000'}
|
|
.validators=${[new IsCountryIBAN('NL')]}
|
|
name="iban"
|
|
label="IBAN"
|
|
></lion-input-iban>
|
|
<br />
|
|
<small>Demo instructions: you can use NL20 INGB 0001 2345 67</small>
|
|
`;
|
|
};
|
|
```
|
|
|
|
## Blacklisted Country
|
|
|
|
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 blocks IBANs from certain countries.
|
|
|
|
You can pass a single string value, or an array of strings.
|
|
|
|
```js preview-story
|
|
export const blacklistedCountry = () => {
|
|
loadDefaultFeedbackMessages();
|
|
return html`
|
|
<lion-input-iban
|
|
.modelValue=${'DE89370400440532013000'}
|
|
.validators=${[new IsNotCountryIBAN(['RO', 'NL'])]}
|
|
name="iban"
|
|
label="IBAN"
|
|
></lion-input-iban>
|
|
<br />

Demo instructions: Try <code>RO 89 RZBR 6997 3728 4864 5577</code> and watch it fail
