NVDA reads all modal content after reading the focused element in modal dialog

阅读更多关于 NVDA reads all modal content after reading the focused element in modal dialog

问题 I have implemented a requirement to focus the first tab(basically an <a> element) present inside the modal dialog. When using NVDA screen reader to test the feature, it is observed that after reading dialog label and description (pointed by aria-labelledby and aria-describedby) it reads the focused tab element. However, after that it continues on to read the entire modal dialog content starting with modal heading. This is not the desired reading behavior we want. If we put focus on the first

How to prevent screen reader from reading src attribute from img tag in IE

阅读更多关于 How to prevent screen reader from reading src attribute from img tag in IE

问题 I am facing a very straight forward problem with screen readers in IE9 or below. When the screen reader looks at an image tag, which has the src attribute, it reads the content of the src . Even if the alt attribute is present, it reads the contents inside the src . To be perfectly clear: this only happens in IE 9 or below Here is a very simple example of my code: <img src="http://placehold.it/100x100" alt="some image"/> I don't understand why this is happening. Any help on how to get around

Can you force a screen reader to read numbers as individual digits?

阅读更多关于 Can you force a screen reader to read numbers as individual digits?

问题 Phone numbers are typically all digits, ignoring parens, dashes, pluses, etc., so input fields for phone numbers are typically numeric. When a screen reader encounters a numeric input field, it'll read the value as a whole number. For example, if I had three input fields for a US phone number, with the first being the area code (3 digits), then the exchange (3 digits), then the line (4 digits), if the fields have 123, 456, 7890 (respectively), the way we'd normally say that number is "one two

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

Distinguish the keypress and click in Mozilla when NVDA is ON

阅读更多关于 Distinguish the keypress and click in Mozilla when NVDA is ON

问题 Requirement is to distinguish the keypress and mouse click events in Mozilla browser. The condition is that the Mozilla browser should be able to distinguish the events (click and enter) when the NVDA IS TURNED ON 回答1: If you're only looking to distinguish between Enter/Space press and mouse/pointer press, I would probably go for using both an onclick and an onmousedown . If the onmousedown is fired, I would set a flag, that I would read in the onclick , telling me whether this was actually

How to make NVDA screen reader read the aria-label?

阅读更多关于 How to make NVDA screen reader read the aria-label?

问题 Screen reader not reading this div: <div tabindex="7" aria-label="Here be redundant or extraneous content" > It should read "Here be redundant or extraneous content" Any help how to solve this problem with HTML? 回答1: A div is neither landmark nor interactive content. An aria-label will not be read by a screen reader (and rightly so). Use an off-screen technique: <div class="sr-only"> Here be redundant or extraneous content </div> The CSS might look like this (accounting for RTL languages too)

How to tell a screen reader to use an attribute instead of the link text?

阅读更多关于 How to tell a screen reader to use an attribute instead of the link text?

问题 I have a link within an unordered list as follows: <li class="savelink"> <a href="/save"><span>Save</span></a> </li> Normally the screen readers read "Save". Is it possible, and with which attribute, to change that without changing the actual link text? The business need is to have a link, styled with an icon. The icon will be complementary to the link text. For example: An icon of a "+" sign and a link text "menu" that is equal to the "add menu item" action. I tried aria-label, with no
