ariaRowCount property of the
ElementInternals interface reflects the value of the
aria-rowcount attribute, which defines the total number of rows in a table, grid, or treegrid.
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.
let ariaRowCount = ElementInternals.ariaRowCount; ElementInternals.ariaRowCount = ariaRowCount;
DOMString which contains an integer.
In this example the value of
ariaRowCount is set to "100".
this.internals_.ariaRowCount = "100";
