ElementInternals: ariaValueMax 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.

The ariaValueMax property of the ElementInternals interface reflects the value of the aria-valuemax attribute, which defines the maximum allowed value for a range widget.

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 which contains a number.

Examples

In this example the value of ariaValueMax is set to "20".

js
this.internals_.ariaValueMax = "20";
