@lion/input-amount

Input Amount >> Overview ||10

A web component based on the generic text input field. Its purpose is to provide a way for users to fill in an amount.

For formatting, we use Intl NumberFormat with some overrides.

For parsing user input, we provide our own parser that takes into account a number of heuristics, locale and ignores invalid characters. Valid characters are digits and separators. Formatting happens on-blur.

If there are no valid characters in the input whatsoever, it will provide an error feedback.

import { html } from '@mdjs/mdjs-preview';
import '@lion/input-amount/define';

export const main = () => {
  return html`
    <lion-input-amount label="Amount" name="amount" currency="USD"></lion-input-amount>
  `;
};
