JAWS 未读取 DIV ARIA-LABEl [英] DIV ARIA-LABEl not being read by JAWS
问题描述
我有一个 angular2 应用程序,我正在将一些动态文本绑定到嵌套 DIV 的 ARIA-LABEl.但是当我使用 JAWS 阅读器在页面上定位 DIV 时,它没有读取指定的文本.这是我正在尝试阅读的文本 - attr.aria-label="Product details for {{productDetails?.ProductName}}"
另外,如果我给这个 div 分配一个标题角色,它会读取动态文本,但不会在文本前添加Product details for"前缀
<div [ngClass]="getDescClass()" class="prdDetails-div" aria-label="some text"><div autofocus attr.aria-label="{{productDetails?.ProductName}} 的产品详情" class="productDetails-name" style="cursor:default!important" role="heading" >{{productDetails?.ProductName}} </div><div autofocus class="products-result-compare"><!--{{getDescription(productDetails?.Description)}}-->小说明
您的描述缺乏细节或工作示例,因此我不能尝试提供解决方案,而是:aria-label
不适用于
.A
既不是地标也不是交互式内容.aria-label
不会被屏幕阅读器读取(这是正确的).在不知道用途的情况下,我有两个建议可能会有所帮助:
将
aria-label
直接放在控件上(知道它会覆盖控件的文本).如果您希望屏幕阅读器用户仅遇到它,请使用一些屏幕外文本.
使用离屏技术:
这里是多余的或无关的内容
CSS 可能看起来像这样(也考虑到 RTL 语言):
.SRonly {位置:绝对!重要;剪辑:矩形(1px 1px 1px 1px);/* IE6, IE7 */剪辑:矩形(1px,1px,1px,1px);顶部:自动;左:-9999px;宽度:1px;高度:1px;溢出:隐藏;}html[dir=rtl] .SRonly {左:继承;左:未设置;右:-9999px;}
还有其他技术,但它们的价值取决于关于您的受众及其技术概况.
你在那些
autofocus
让我很紧张.我希望您不要将它们用作交互式控件(如按钮).理想情况下 永远不要使用 div
作为互动内容.I have an angular2 application and I am binding some dynamic text to ARIA-LABEl for a nested DIV. But when I use the JAWS reader to locate DIVs on the page , it is not reading the assigned text.This is the text I am trying to read - attr.aria-label="Product details for {{productDetails?.ProductName}}"
Also if I give assign a role of heading to this div, it reads the dynamic text but doesn't prefix "Product details for " before the text
<div [ngClass]="getDescClass()" class="prdDetails-div" aria-label="some text">
<div autofocus attr.aria-label="Product details for {{productDetails?.ProductName}}" class="productDetails-name" style="cursor:default!important" role="heading" >{{productDetails?.ProductName}} </div>
<div autofocus class="products-result-compare">
<!--{{getDescription(productDetails?.Description)}}-->
Small description
</div>
Your description lacks detail or a working example, so instead of trying to offer a solution all I can offer is this: aria-label
does not work on <div>
nor <span>
.
A <div>
and <span>
are neither landmarks nor interactive content. An aria-label
will not be read by a screen reader (and rightly so).
Without knowing the use, I have two suggestions which might help:
Put the
aria-label
directly on the control (knowing it will override the text of the control).Use some off-screen text if you want it to be encountered only by screen reader users.
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):
.SRonly {
position: absolute !important;
clip: rect(1px 1px 1px 1px); /* IE6, IE7 */
clip: rect(1px, 1px, 1px, 1px);
top: auto;
left: -9999px;
width: 1px;
height: 1px;
overflow: hidden;
}
html[dir=rtl] .SRonly {
left: inherit;
left: unset;
right: -9999px;
}
There are other techniques, but their value depends on your audience and its technology profile.
Your use of autofocus
on those <div>
makes me nervous. I hope you are not using them as interactive controls (like buttons). Ideally never use a div
as interactive content.
