IIRC the other settings are off and assertive. The "polite" setting tells the screen reader that it should read the new content but not interrupt what is currently being said. I've added the aria-live="polite" to my html. I needed to tell the screen reader that the page has changed and that it needs to read the content again. This is a short abstract, but the following article can give you more informations about the parsing of the DOM by screen readers: For that matter, you can use aria-live attribute. Now, evidently, if your screenreader reads the content before it was modified by javascript, it won't have any clue about modifications made by javascript. That because, your screen reader will not access the DOM directly on the load of the page, but will interact with the Accessibility API provided by your browser. This means that if your browser understands javascript, your screenreader will. They don't parse the HTML directly but an accessible tree view of a document. ) or to play a flash player game, as long as those programs provide the correct informations to their Accessibility API.

They do not have to know anything about Javascript, or about the real DOM and HTML (with the sole exception of ChromeVox).įor that reason, the same screenreader will be used to consult Internet with your favorite browser, to write mail with your favorite program (Thunderbird, Outlook.

Modern screen readers use the Accessibility API. "Generally, access the DOM (Document Object Model), and they use browser APIs (Application Programming Interfaces) to get the information they need."

Since you say you are "creating a website for a reading service for the blind and visually impaired" the onus is really on you to learn the tools and how to test with them. This does not, however, address cases where the script block you want to show fails for other reasons (network lag, bugs, etc). If a browser has script enabled, this will not render (which is good). Please enable JavaScript to receive this content. Then, if you find that your script modifies the DOM after the screen reader has already parsed it, explore ARIA live regions and then look at browser support.įinally, your example above about detecting if script is enabled doesn't actually need script to work if you use the element: Get a list of keyboard shortcuts for many screen readers.There are plenty of tutorials to get you up and running.

I offer this answer primarily because you haven't offered any code to test ("some stuff to some of the pages" is not code to test) and your example doesn't provide enough context. You can test this without needing to know how screen readers parse the DOM. So this morning I added this: Please enable JavaScript to receive this content.īut if the problem isn't that JavaScript needs to be enabled ( a recent survey shows that 99% of screen-reader users have JavaScript enabled) then the problem is not solved and is made even worse because now the screen reader user would think that JavaScript is not enabled. Then, we started getting a few emails of confused listeners wondering what happened to the Now Playing link. So as you can see, if the screen reader doesn't read what the javascript/jquery prints to the #now-playing-div then it will read nothing.

invoke the audio-reader javascript library It uses a function that determines what program we have playing over the air and then prints the name of the program and a link to listen to it. Here's an example of one of the pages that I use JavaScript on. do screen readers take a copy of the whole DOM and then parse it and read it? Or do they read the DOM, the same one that jQuery works on? Will the screen reader read the content that is printed to the page with jquery after the page has been loaded?įrom this page - "Generally, access the DOM (Document Object Model), and they use browser APIs (Application Programming Interfaces) to get the information they need."Īnd we know that jQuery is a DOM manipulation library. I'm creating a website for a reading service for the blind and visually impaired and I'm using JavaScript (with jQuery) to print some stuff to some of the pages after the page has loaded.
