Element: ariaColSpan property
Baseline 2023Newly 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 ariaColSpan
property of the Element
interface reflects the value of the aria-colspan
attribute, which defines the number of columns spanned by a cell or gridcell within a table, grid, or treegrid.
Value
A string which contains an integer.
Examples
In this example the aria-colspan
attribute on the element with an ID of spanning-heading
is set to "2". Using ariaColSpan
we update the value to "3".
html
<table>
<tr>
<th>Heading 1</th>
<th>Heading 2</th>
<th>Heading 3</td>
</tr>
<tr>
<td colspan="2" aria-colspan="2" id="spanning-column">Spanning</td>
<td>One</td>
</tr>
</table>
js
let el = document.getElementById("spanning-column");
console.log(el.ariaColSpan);
el.ariaColSpan = "3";
console.log(el.ariaColSpan);
