ElementInternals: ariaRequired property
The ariaRequired
property of the Element
interface reflects the value of the aria-required
attribute, which indicates that user input is required on the element before a form may be submitted.
Note: Setting aria attributes on ElementInternals
allows default semantics to be defined on a custom element. These may be overwritten by author-defined attributes, but ensure that default semantics are retained should the author delete those attributes, or fail to add them at all. For more information see the Accessibility Object Model explainer.
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.
Examples
In this example the value of ariaRequired
is set to "true".
js
this.internals_.ariaRequired = "true";
