Element: ariaRowCount property

Baseline 2023

Newly available

Since October 2023, this feature works across the latest devices and browser versions. This feature might not work in older devices or browsers.

The ariaRowCount property of the Element interface reflects the value of the aria-rowcount attribute, which defines the total number of rows in a table, grid, or treegrid.

Value

A string which contains an integer.

Examples

In this example the aria-rowcount attribute on the element with an ID of semantic-table is set to "100", representing the total number of rows in the table, rather than the currently visible rows. Using ariaRowCount we update the value to "101".
