Element: ariaRequired property

Baseline 2023

Newly available

Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

TheariaRequired property of theElement interface reflects the value of thearia-required attribute, which indicates that user input is required on the element before a form may be submitted.

Note:Where possible use an HTML<input> element withtype="text" or a<textarea> as these have built in semantics and do not require ARIA attributes.

Value

A string with one of the following values:

"true": Users need to provide input on an element before a form is submitted.
"false": User input is not necessary to submit the form.

In this example thearia-required attribute on the element with an ID oftxtBoxInput is set to "true" indicating that this input must be completed. UsingariaRequired we update the value to "false".
