No previous message | Next message →
For a desktop Single Page Application, (where there are not really page
refreshes, just changes of content), nothing announces when the view
changes. The one I'm looking at they actually do update the page title, but
I hear nothing.
What's the best way of handling this? Will the title announce if focus is
placed on the document? Should they place focus on each view's top level
heading (and hope each view has one)? ...or something else?

Hello,
I found this article to be quite useful on understanding different approaches.
What we learned from user testing of accessible client-side routing techniques with Fable Tech Labs | GatsbyJSaddress edit text has alternate items Search or enter website name
By: Marcy Sutton <https://www.gatsbyjs.org/contributors/marcy-sutton/>

She not only discusses how they set up testing, but also how it different approaches helped different clients. I believe the final approach was to focus on a div containing the new content causing the screen reader to read it. My main issue with this approach as a primary JAWS user, is that JAWS expects focus to be set on a control and not on content, so Braille display and visual Virtual cursor tracking usually remain on the first line of that DIV even while speech reads the entire thing.
Best Wishes,
Jonathan
