ElementInternals.ariaLevel

The ariaLevel property of the ElementInternals interface reflects the value of the aria-level attribute, which defines the hierarchical level of an element within a structure.

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.

Syntax

ElementInternals.ariaLevel = ariaLevel;

Value

A DOMString containing an integer.

Examples
