Input Email: Use Cases

import { html } from '@mdjs/mdjs-preview';
import { Validator } from '@lion/ui/form-core.js';
import '@lion/ui/define/lion-input-email.js';

Faulty Prefilled

When prefilling with a faulty input, an error feedback message will show.

Use loadDefaultFeedbackMessages to get our default feedback messages displayed on it.

export const faultyPrefilled = () => html`
  <lion-input-email .modelValue="${'foo'}" label="Email"></lion-input-email>
`;

Custom Validator

export const customValidator = () => {
  class GmailOnly extends Validator {
    static get validatorName() {
      return 'GmailOnly';
    }
    execute(value) {
      let hasError = false;
      if (!(value.indexOf('gmail.com') !== -1)) {
        hasError = true;
      }
      return hasError;
    }
    static async getMessage() {
      return 'You can only use gmail.com email addresses.';
    }
  }
  return html`
    <lion-input-email
      .modelValue="${'foo@bar.com'}"
      .validators="${[new GmailOnly()]}"
      label="Email"
    ></lion-input-email>
  `;
