何时使用必需属性与输入元素的aria

本文介绍了何时使用必需属性与输入元素的aria-required属性?的处理方法,对大家解决问题具有一定的参考价值,需要的朋友们下面随着小编来一起学习吧!

问题描述

我正在尝试使表单可访问。我是否应该输入必需 aria-required 属性,或只有一个?

I'm trying to make a form accessible. Should I make my inputs have both required and aria-required attributes, or just one?

<label for="textbox1">Input</label>
<input id="textbox1" type="text" name="Text Box" required>

或者这样?

<label for="textbox1">Input</label>
<input id="textbox1" type="text" name="Text Box" aria-required="true">

或者这样?

<label for="textbox1">Input</label>
<input id="textbox1" type="text" name="Text Box" aria-required="true" required>

文章声称最好同时实现它们。

The article Accessible HTML5 Forms – Required Inputs claims it is best to implement both.

推荐答案

当John Foliot在2012年写这篇文章时,这是非常真实的。你需要两者。

When John Foliot wrote that article in 2012 it was very much true. You needed both.

今天不再是这种情况了。我可以举个例子,把它放在CodePen中,并在JAWS和NVDA中查看(对不起,没有VoiceOver)今天):

Today that is no longer the case. I can take your example, put it in a CodePen, and check it in JAWS and NVDA (sorry, no VoiceOver today):

<label for="textbox1">Input</label>
<input id="textbox1" type="text" name="Text Box" required>

您将很高兴知道NVDA和JAWS都会根据需要宣布该字段。

You will be happy to know that both NVDA and JAWS announce the field as required.

简而言之,需要 aria-required 。只需使用 required

In short, you do not need aria-required any longer. Just use required.

您可以阅读更多关于您可以在本文中转储的ARIA属性的信息。 2015年Faulkner(ARIA规范的编辑之一):

You can read a bit more about the ARIA attributes you can dump in this article by Steve Faulkner (one of the editors of the ARIA spec) from 2015: http://html5doctor.com/on-html-belts-and-aria-braces/
