RE: Element.getComputedRole()

From: Richard Schwerdtfeger [mailto:schwer@us.ibm.com]


What is critically important when we go to ARIA 1.1 is if an author chooses to not add an ARIA role to fulfill the design of compound widget (like a Grid) then if the semantics match the design pattern it should work. Here is an example:

<table role="grid">
<row>
<!—The author is using a non-standard HTML element (“row”) instead of TR. The ARIA role is presumably inferred from the name of the element. -->



<th role="columnheader">foo</th>
</row>
<row>
<td role="gridcell">foo</td>
</row>
</table>

I hope I’m interpreting the above correctly. If so, then a custom element such as <grid> would be given a “grid” role, too. The Web Apps working group is working on technologies that would associate code, and hence behavior, with such custom-defined elements.
