Text console for development in JAWS?

由 二次信任 提交于 2019-12-21 12:18:36
问题 I'm working on a web application and I want to make it easy to use via screen reader. Testing stuff in JAWS is time consuming. Is it possible to make JAWS display text instead of reading it? I don't want actually to hear the content during development. I just want to see what would be read by JAWS. 回答1: There is no speech viewer for Jaws, as far as I know. However, you can make it write all speech output to a log file using the "/z" switch. Unfortunately, you cannot view the log file in a

问题 Are there any benefits of using the following code? <ul role="list"> <li role="listitem"></li> <li role="listitem"></li> <li role="listitem"></li> </ul> Does the following code have the same meaning to assistive technologies? <ul> <li></li> <li></li> <li></li> </ul> 回答1: The answer is yes, assistive technologies work well when correct semantic markup is used for structuring the document.

How does CSS opacity affect accessibility?

由 喜欢而已 提交于 2019-12-20 17:28:11
问题 After browsing a number of Google and other SO articles, I've decided to ask my question plainly in hopes of a simple, direct answer. To add one further step to the discussion on Does opacity:0 have exactly the same effect as visibility:hidden: I understand that display:none and visibility:hidden hide elements from screenreaders and the like, but what about opacity:0 ? The table in one of the answers to the linked question notes that opacity participates in taborder , so does that necessarily

由 馋奶兔 提交于 2019-12-20 09:37:42
问题 I'm trying to get an aria-live region to work correctly with JAWS 11 and IE8. Using the code below, I can get JAWS to announce the new value when the button is clicked, but the behaviour is not what I would expect. JSFiddle of this example <!DOCTYPE html> <html> <head></head> <body> <button onclick="document.getElementById('statusbar').innerHTML = parseInt(document.getElementById('statusbar').innerHTML) + 1">Update</button> <div id="statusbar" aria-live="polite">0</div> </body> </html> Using

aria-labelledby not working with NVDA/Firefox

由 强颜欢笑 提交于 2019-12-20 05:17:27
问题 I need some help to make NVDA screen reader read a custom description of a math expression I've written in my index.html. The math expression is inside of a sentence. So it looks pretty much like this: <div> some text here... ε<sub>x</sub> = -200(10<sup>-6</sup>), ε<sub>y</sub> = 550(10<sup>-6</sup>), γ<sub>xy</sub> = 150(10<sup>-6</sup>) some more text here... <div> The problem is that screen readers do not read the superscripts nor the minus symbols. To fix this problem I added a aria

Is presence of aria-hidden sufficient or is value set to “true” required (aria-hidden=“true”)

由 吃可爱长大的小学妹 提交于 2019-12-20 03:07:07
问题 The html "hidden" attribute is a boolean and does NOT need a value set. It's mere presence is sufficient. What about the "aria-hidden" attribute? Is it's mere presence sufficient? Or does it require the value "true" to be set? 回答1: aria-hidden must have a value of true|false. Note, however, that aria-hidden is not needed if you are using the hidden attribute or if you are using CSS visibility:none or display:hidden . All three of these latter three ways to hide will also hide the element from
