Summary

Inconsistent Live Region output when dynamically adding ARIA roles/attributes

  1. Save as HTML file:
<!DOCTYPE html>
<html lang="en">
	<head>
		<meta charset="utf-8">
		<title>live region</title>
	</head>
	<body>
		<div id=1>
			content of live region
		</div>
		
		<button onClick="document.getElementById('1').setAttribute('role','alert');">add alert</button>
		<button onClick="document.getElementById('1').removeAttribute('role');">remove alert</button>
		<button onClick="document.getElementById('1').setAttribute('aria-live','assertive');">add aria-live</button>
		<button onClick="document.getElementById('1').removeAttribute('aria-live');">remove aria-live</button>	
		
	</body>
</html>
  1. Activate all four buttons one after the other

Expected result

  • Since ARIA roles may not be added dynamically, but ARIA attributes can be added, output should only occur when aria-live is added and not when role=alert is added
  • Output should be consistent in all browsers

Actual result

  • no output when adding aria-live, but when adding role=alert (Chrome, Firefox)
  • no output at all in IE 11 when dynamically adding aria-live or role=alert

See also https://github.com/w3c/aria-practices/issues/78 and many other problems with live regions: https://github.com/FreedomScientific/VFO-standards-support/issues?q=live+region

The live region is output as follows:

Chrome

alert: yes aria-live: no

IE 11

alert: no aria-live: no

Firefox

alert: yes aria-live: no

can you point to the normative words about your statement in the spec?

This was in the ARIA specification 5 years ago, but has been removed
