RadioNodeList: value property

View on MDN ↗

If the underlying element collection contains radio buttons, the RadioNodeList.value property represents the checked radio button. On retrieving the value property, the value of the currently checked radio button is returned as a string. If the collection does not contain any radio buttons or none of the radio buttons in the collection is in checked state, the empty string is returned. On setting the value property, the first radio button input element whose value property is equal to the new value will be set to checked.

Example

HTML

<form>
  <label><input type="radio" name="color" value="blue" />Blue</label>
  <label><input type="radio" name="color" value="red" />Red</label>
</form>

JavaScript

// Get the form
const form = document.forms[0];

// Get the form's radio buttons
const radios = form.elements["color"];

// Choose the "red" option
radios.value = "red";
