JAWS不会在IE中的选择框中宣布aria-describedby [英] JAWS does not announce aria-describedby on select box in IE

问题描述

我试图在选择框上使用aria-describeby，但JAWS不会在IE中宣布使用aria-describedby属性关联的文本。我甚至将tabindex = - 1添加到被引用的span标记中。下面是我使用的示例代码。

I am trying to use aria-describedby on select box, but JAWS does not announce the text associated using the aria-describedby attribute in IE. I have even added tabindex="-1" to the span tag which is being referenced.Below is the sample code I am using. Can somebody please provide me any information on this topic.

<form action="#" method="post">
  <div>
    <label for="State">State</label> 
    <select  id="State" name="State" aria-describedby="spanId">
      <option value="acct">Choose</option>
      <option value="act">ACT</option>
      <option value="nsw">NSW</option>
      <option value="nt">NT</option>
      <option value="qld">QLD</option>
      <option value="sa">SA</option>
      <option value="tas">TAS</option>
      <option value="vic">VIC</option>
      <option value="wa">WA</option>
      </select>
      <span id="spanId" tabindex="-1">This is the text</span>
  </div>

</form>

推荐答案

使用IE11和Jaws 17好。

Using IE11 and Jaws 17 I have observed this issue as well.

我认为这是一个错误。

在Freedom Scientific解决之前，我建议使用 aria-labelledby 。

Until it's addressed by Freedom Scientific, I'd recommend using aria-labelledby.

这意味着语义上略有不同：

This means something slightly different semantically:

一个标签描述了一个对象的本质，而描述
提供了用户可能需要的更多信息。

a label describes the essence of an object, while a description provides more information that the user might need.

但它可能是您拥有的最佳替代品。

But it's probably the best substitute you have available.
