ElementInternals: ariaLevel property
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.
Value
A string containing an integer.
Examples
In this example the value of ariaLevel
is set to "1".
js
this.internals_.ariaLevel = "1";
