Validation

Link to This Section

Setting the required attribute to make selecting an option mandatory. If a value has not been selected, it will prevent the form from submitting and display an error message.

  
    Option 1
    Option 2
    Option 3
  
  Submit

<form class="validation">
  <wa-radio-group label="Select an option" name="a" required>
    <wa-radio value="1">Option 1</wa-radio>
    <wa-radio value="2">Option 2</wa-radio>
    <wa-radio value="3">Option 3</wa-radio>
  </wa-radio-group>
  <br />
  <wa-button appearance="filled" type="submit" variant="neutral">Submit</wa-button>
</form>

<script>
  const form = document.querySelector('.validation');

  // Handle form submit
  form.addEventListener('submit', event => {
    event.preventDefault();
    alert('All fields are valid!');
  });
</script>

Custom Validity

Link to This Section

Use the setCustomValidity() method to set a custom validation message. This will prevent the form from submitting and make the browser display the error message you provide. To clear the error, call this function with an empty string.

  
    Not me
    Me neither
    Choose me
  
  Submit

<form class="custom-validity">
  <wa-radio-group label="Select an option" name="a" value="1">
    <wa-radio value="1">Not me</wa-radio>
    <wa-radio value="2">Me neither</wa-radio>
    <wa-radio value="3">Choose me</wa-radio>
  </wa-radio-group>
  <br />
  <wa-button appearance="filled" type="submit" variant="neutral">Submit</wa-button>
</form>

<script>
  const form = document.querySelector('.custom-validity');
  const radioGroup = form.querySelector('wa-radio-group');
  const errorMessage = 'You must choose the last option';

  // Set initial validity as soon as the element is defined
  customElements.whenDefined('wa-radio-group').then(() => {
    radioGroup.setCustomValidity(errorMessage);
  });

  // Update validity when a selection is made
  form.addEventListener('change', () => {
    const isValid = radioGroup.value === '3';
    radioGroup.setCustomValidity(isValid ? '' : errorMessage);
  });

  // Handle form submit
  form.addEventListener('submit', event => {
    event.preventDefault();
    alert('All fields are valid!');
  });
</script>

Slots

Link to This Section

Learn more about using slots.

Name	Description
(default)	The default slot where `<wa-radio>` elements are placed.

`label`	The radio group's label. Required for proper accessibility. Alternatively, you can use the `label` attribute.

Attributes & Properties

Link to This Section

Learn more about attributes and properties.

Name	Description	Reflects
`defaultValue` `value`	The default value of the form control. Primarily used for resetting the form control. Type `string \| null`
`disabled` `disabled`	Disables the radio group and all child radios. Type `boolean` Default `false`
`form`	By default, form controls are associated with the nearest containing `<form>` element. This attribute allows you to place the form control outside of a form and associate it with the form that has this `id`. The form must be in the same document or shadow root for this to work. Type `HTMLFormElement \| null`
`hint` `hint`	The radio groups's hint. If you need to display HTML, use the `hint` slot instead. Type `string` Default `''`
`label` `label`	The radio group's label. Required for proper accessibility. If you need to display HTML, use the `label` slot instead. Type `string` Default `''`
`name` `name`	The name of the radio group, submitted as a name/value pair with form data. Type `string \| null` Default `null`
`orientation` `orientation`	The orientation in which to show radio items. Type `'horizontal' \| 'vertical'` Default `'vertical'`
`required` `required`	Ensures a child radio is checked before allowing the containing form to submit. Type `boolean` Default `false`
`size` `size`	The radio group's size. When present, this size will be applied to all `<wa-radio>` items inside. Type `'xs' \| 's' \| 'm' \| 'l' \| 'xl' \| 'small' \| 'medium' \| 'large'`
`validationTarget`	We use the first available radio as the validationTarget similar to native HTML that shows the validation popup on the first radio element. Type `undefined \| HTMLElement`
`validators`	Validators are static because they have `observedAttributes`, essentially attributes to "watch" for changes. Whenever these attributes change, we want to be notified and update the validator. Type `Validator[]` Default `[]`
`value`	The current value of the radio group, submitted as a name/value pair with form data.
`withHint` `with-hint`	Only required for SSR. Set to `true` if you're slotting in a `hint` element so the server-rendered markup includes the hint before the component hydrates on the client. Type `boolean` Default `false`
`withLabel` `with-label`	Only required for SSR. Set to `true` if you're slotting in a `label` element so the server-rendered markup includes the label before the component hydrates on the client. Type `boolean` Default `false`

Methods

Link to This Section

Learn more about methods.

Name	Description	Arguments
`focus()`	Sets focus on the radio group.	`options: FocusOptions`
`formStateRestoreCallback()`	Called when the browser is trying to restore element’s state to state in which case reason is "restore", or when the browser is trying to fulfill autofill on behalf of user in which case reason is "autocomplete". In the case of "restore", state is a string, File, or FormData object previously set as the second argument to setFormValue.	`state: string \| File \| FormData \| null, reason: 'autocomplete' \| 'restore'`
`resetValidity()`	Reset validity is a way of removing manual custom errors and native validation.
`setCustomValidity()`	Do not use this when creating a "Validator". This is intended for end users of components. We track manually defined custom errors so we don't clear them on accident in our validators.	`message: string`

Events
