ElementInternals: ariaReadOnly property

The ariaReadOnly property of the ElementInternals interface reflects the value of the aria-readonly attribute, which indicates that the element is not editable, but is otherwise operable.

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.


A string with one of the following values:


The user cannot change the value of the element.


The user can set the value of the element.


In this example the value of ariaReadOnly is set to "true".

this.internals_.ariaReadonly = "true";
