ElementInternals: ariaRowIndex property

Baseline Widely available

This feature is well established and works across many devices and browser versions. It’s been available across browsers since October 2023.

The ariaRowIndex property of the ElementInternals 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.

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

A string which contains an integer.

Examples

In this example the value of ariaRowIndex is set to "1".

js
class CustomEl extends HTMLElement {
  constructor() {
    super();
    this.internals_ = this.attachInternals();
    this.internals_.ariaRowIndex = "1";
  }
  // …
}
