微格式的类结构是否适合屏幕阅读器？

和这个（假设两个代码具有相同的内容信息）

哪种方法适用于可访问性和纯文本浏览器？屏幕阅读器在这两种方法下的表现如何？

If I have a form that updates via AJAX, there is a chance that the original value field (as it was output to the browser) will not match the text that the form field now has inside.

I know from a blind user that I help on occasion that Jaws 9 and later has strong support for rich internet applications (specifically AJAX and DOM changes) but I'm not sure if this support goes back as far as Jaws 7 (as their release history implies).

Basically, there are two concerns:

• If I load the form totally blank with no values set, and then use AJAX to load the data on page load (or after user hits a button), will Jaws read the inserted values?

• If I load the form with values set and those values change via AJAX will the reader read what is in the values or on screen?

My hope is that this is a case where deficiencies of the older versions will work to my favor, and that it always reads whatever is on screen (in the input fields) and disregards the values. And that it expects form values to change so it reads whatever is current, not just what loads.

But of course I'd rather know for sure rather than find out otherwise later.
