{{DefaultAPISidebar("DOM")}}

The **`ariaRowIndex`** property of the {{domxref("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.

## Syntax

    var ariaRowIndex = element.ariaRowIndex;
    element.ariaRowIndex = ariaRowIndex

### Value

A {{domxref("DOMString")}} 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".

```html
<table id="semantic-table" role="table" aria-label="Semantic Elements" aria-describedby="semantic_elements_table_desc" aria-rowcount="100">
  <caption id="semantic_elements_table_desc">Semantic Elements to use instead of ARIA's roles</caption>
  <thead role="rowgroup">
    <tr role="row">
      <th role="columnheader" id="role-heading" aria-sort="none" aria-rowindex="1">ARIA Role</th>
      <th role="columnheader" id="element-heading" aria-sort="none" aria-rowindex="1">Semantic Element</th>
    </tr>
  </thead>
  <tbody role="rowgroup">
    <tr role="row">
      <td role="cell" aria-rowindex="11">header</td>
      <td role="cell" aria-rowindex="11">h1</td>
    </tr>
    <tr role="row">
      <td role="cell" aria-rowindex="16">header</td>
      <td role="cell" aria-rowindex="16">h6</td>
    </tr>
    <tr role="row">
      <td role="cell" aria-rowindex="18">rowgroup</td>
      <td role="cell" aria-rowindex="18">thead</td>
    </tr>
    <tr role="row">
      <td role="cell" aria-rowindex="24">term</td>
      <td role="cell" aria-rowindex="24">dt</td>
    </tr>
  </tbody>
</table>
```

```js
let el = document.getElementById('role-heading');
console.log(el.ariaRowIndex); // 1
el.ariaRowIndex = "2"
console.log(el.ariaRowIndex); // 2
```
