{{APIRef("DOM")}}
The ariaChecked property of the {{domxref("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 {{htmlelement("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:
"true"
"mixed"
"false"
"undefined"
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".
<span
role="checkbox"
id="checkBoxInput"
aria-checked="false"
tabindex="0"
aria-labelledby="chk1-label">
</span>
<label id="chk1-label">Remember my preferences</label>
let el = document.getElementById("checkBoxInput");
console.log(el.ariaChecked); // "false"
el.ariaChecked = "true";
console.log(el.ariaChecked); // "true"
