Input

<mo-input> | MOInput
Since 1.0 stable

Inputs collect data from the user.

<mo-input></mo-input>
import { MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => <MOInput />;

Examples

Labels

Use the label attribute to give the input an accessible label. For labels that contain HTML, use the label slot instead.

<mo-input label="What is your name?"></mo-input>
<div></div>
import { MOIcon, MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => <MOInput label="What is your name?" />;

Placeholders

Use the placeholder attribute to add a placeholder.

<mo-input placeholder="Type something"></mo-input>
import { MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => <MOInput placeholder="Type something" />;

Help text

Add descriptive help text to an input with the help-text attribute. For help texts that contain HTML, use the help-text slot instead.

<mo-input label="Nickname" help-text="What would you like people to call you?"></mo-input>
import { MOIcon, MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => <MOInput label="Nickname" help-text="What would you like people to call you?" />;

Error and success text

If you wish to use third party error validation, use the errorText and successText attribute to show the error message. The error message will override the help text for the duration that it is visible.

If you wish to show the state without having a message, use the success and error boolean attributes instead.

<mo-input
  id="error"
  help-text="Please enter the postal code in format '12345'."
  label="Postal code"
  placeholder="01300"
>
</mo-input>

<script>
  const input = document.getElementById('error');
  input.addEventListener('mo-blur', () => {
    if (input.value.length === 5 && !isNaN(input.value)) {
      input.successText = 'The format is correct.';
      input.errorText = '';
    } else {
      input.errorText = "The postal code must be in format '12345'";
      input.successText = '';
    }
  });
</script>
import { MOIcon, MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (
  <MOInput helpText="Please enter the postal code in format '12345'." label="Postal code" placeholder="01300" />
);

Clearable

Add the clearable attribute to add a clear button when the input has content.

<mo-input placeholder="Clearable" clearable></mo-input>
import { MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => <MOInput placeholder="Clearable" clearable />;

Toggle password

Add the password-toggle attribute to add a toggle button that will show the password when activated.



<mo-input type="password" placeholder="Password Toggle" size="small" password-toggle></mo-input>
<br />
<mo-input type="password" placeholder="Password Toggle" size="medium" password-toggle></mo-input>
<br />
<mo-input type="password" placeholder="Password Toggle" size="large" password-toggle></mo-input>
import { MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (
  <>
    <MOInput type="password" placeholder="Password Toggle" size="small" toggle-password />
    <br />
    <MOInput type="password" placeholder="Password Toggle" size="medium" toggle-password />
    <br />
    <MOInput type="password" placeholder="Password Toggle" size="large" toggle-password />
  </>
);

Filled inputs

The type attribute controls the type of input the browser renders.

<br />
<mo-input type="number" Placeholder="Number"></mo-input>
<br />
<mo-input type="date" Placeholder="Date"></mo-input>
import { MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (
  <>
    <MOInput type="email" Placeholder="Email" />
    <br />
    <MOInput type="number" Placeholder="Number" />
    <br />
    <MOInput type="date" Placeholder="Date" />
  </>
);

Disabled

Use the disabled attribute to disable an input.



<mo-input placeholder="Disabled" size="small" disabled></mo-input>
<br />
<mo-input placeholder="Disabled" size="medium" disabled></mo-input>
<br />
<mo-input placeholder="Disabled" size="large" disabled></mo-input>
import { MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => (

    <br />
    <MOInput placeholder="Disabled" size="medium" disabled />
    <br />
    <MOInput placeholder="Disabled" size="large" disabled />
  </>
);

    <br />
    <MOInput label="Phone number" placeholder="123-456-7890" size="large" required />
  </>
);

<br />
<mo-input help-text="Additional instructions" label="Medium" placeholder="Placeholder" size="medium"></mo-input>
<br />
<mo-input help-text="Additional instructions" label="Large" placeholder="Placeholder" size="large"></mo-input>

Custom validation

Inputs inside a form can be validated for errors on form submission. Check form controls to learn more about form submission and client-side validation.


Submit
<form class="input-validation-pattern">
  <mo-input name="letters" required label="Letters only" pattern="[A-Za-z]+"></mo-input>
  <br />
  <mo-button type="submit" variant="primary">Submit</mo-button>
</form>

<script type="module">
  const form = document.querySelector('.input-validation-pattern');

  // Wait for controls to be defined before attaching form listeners
  await Promise.all([
    customElements.whenDefined('mo-button'),
    customElements.whenDefined('mo-input'),
  ]).then(() => {
    form.addEventListener('submit', event => {
      event.preventDefault();
      alert('All fields are valid!');
    });
  });
</script>
import { MOButton, MOInput } from '@metsooutotec/modes-web-components/dist/react';

const App = () => {
  function handleSubmit(event) {
    event.preventDefault();
    alert('All fields are valid!');
  }

  return (
    <form onSubmit={handleSubmit}>
      <MOInput name="letters" required label="Letters only" pattern="[A-Za-z]+" />
