ariaChecked property of the
Element interface reflects the value of the
aria-checked attribute, which indicates the current "checked" state of checkboxes, radio buttons, and other widgets that have a checked state.
Note: Where possible use an HTML
<input> element with
type="checkbox" as this element has built in semantics and does not require ARIA attributes.
A string with one of the following values:
The element is checked.
Indicates a mixed mode value for a tri-state checkbox or menuitemcheckbox.
The element supports being checked but is not currently checked.
The element does not support being checked.
In this example the
aria-checked attribute on the element with an ID of
checkBoxInput is set to "false" indicating that this input is currently unchecked. Using
ariaChecked we update the value to "true".
<label id="chk1-label">Remember my preferences</label>
let el = document.getElementById("checkBoxInput");
el.ariaChecked = "true";
