Element: role property
Baseline 2023Newly available
Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.
The role
property of the Element
interface returns the explicitly set WAI-ARIA role for the element.
All HTML elements have an implicit ARIA role, even if that role is generic
. This semantic association allows tools to present and support interaction with the object in a manner that is consistent with user expectations about other objects of that type. The role
attribute is used to explicitly set the element's ARIA role, overriding the implicit role. For example, a <ul>
, which has an implicit list
role, might have role="treegrid"
explicitly set. The role
property reflects the explicitly set value of the role
attribute—in this case treegrid
; it does not return the element's implicit list
role unless explicitly set.
The full list of defined ARIA roles can be found on the ARIA roles reference page.
Value
A string; the value of the role
attribute or null
if not explicitly set.
Examples
In this example, images with empty or missing alt
attributes are given a role
of presentation
:
const images = document.querySelectorAll("img");
images.forEach((image) => {
if (!image.alt) {
image.role = "presentation";
}
});
