Standards information

Remarks

Used in Roles
No role required.

 

The ariaLive attribute indicates the priority of updates to a live region. Announcing changes immediately can be disorienting for users. Most updates should be announced only when the user is idle.

To supress notifications until after a region has finished updating, set ariaBusy.

Note  For cross-browser compatibility, always use the WAI-ARIA attribute syntax to access and modify ARIA properties; for example, object.setAttribute("aria-valuenow", newValue).
