在页面部分（哈希）link 上使用 role=button 在语义上是否正确？
Is it semantically correct to use role=button on a page section (hash) link?
我有指向页面中部分的链接。为了提高可访问性，我向这些添加了 role="button" 属性，因为我的理解是这些链接在页面内并且只是转到一个部分。但是我不确定这样做是否合适。
<ul>
<li><a role="button" href='#section1'>Go to section 1</a></li>
<li><a role="button" href='#section2'>Go to section 2</a></li>
</ul>
<div style="height:15rem"></div>
<h2 id='section1'>Section 1</h2>
<div style="height:15rem"></div>
<h2 id='section2'>Section 2</h2>

您有链接，这些链接起到链接的作用。他们链接到同一页面的另一部分并不能使他们成为按钮。
见WAI-ARIA Authoring Practices 1.1
A button is a widget that enables users to trigger an action or event, such as submitting a form, opening a dialog, canceling an action, or performing a delete operation.
你正在做 none 这些事情。
它还说：
The types of actions performed by buttons are distinctly different from the function of a link (see link pattern). It is important that both the appearance and role of a widget match the function it provides. Nevertheless, elements occasionally have the visual style of a link but perform the action of a button. In such cases, giving the element role button helps assistive technology users understand the function of the element. However, a better solution is to adjust the visual design so it matches the function and ARIA role.
…这突出了链接是另一回事。
