Element: ariaRowIndex 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 ariaRowIndex property of the Element interface reflects the value of the aria-rowindex attribute, which defines an element's row index or position with respect to the total number of rows within a table, grid, or treegrid.
Value
A string which contains an integer.
Examples
In this example the aria-rowindex attribute on the element with an ID of role-heading is set to "1". Using ariaRowIndex we update the value to "2".
