ElementInternals.ariaMultiline
The ariaMultiline
property of the ElementInternals
interface reflects the value of the aria-multiline
attribute, which indicates whether a text box accepts multiple lines of input or only a single line.
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

with one of the following values:
"true"
-
This is a multi-line text box.
"false"
-

Examples

is set to "true".
