在Firefox上，有没有aria = live =“ assertive”没有role =“ alert”的方法吗？

Question

Is there any tricks to get aria-live working without role="alert" in firefox on windows? (using JAWS). It seems to only work with role="alert" which announces "Alert" before each message in the live area which is unfortunately ruining my browser game experience on firefox.

Thanks anyone who tries

 $(document).ready(function() { $("#controls").delegate("a", "click", function() { $("#alert-div").empty().append(" "); var text = $(this).attr("data-test"); window.setTimeout(function(){ $("#alert-div").empty().append(text); }, 500); }); }); 

 <script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script> <div id="alert-div" aria-live="polite" aria-atomic="true"> </div> <div id="controls"> <a href="javascript:;" data-test="Say this message">A</a> <a href="javascript:;" data-test="A different message">B</a> </div>

Have you tried starting out simple and just have aria-live=polite and leave off the role and aria-atomic ? We use aria-live all the time with great success.
