What is the difference between aria-label and title attributes?
提问by Alain Tiemblo
I am used to use title=""attribute on my links/buttons/... to detail them. But bootstrap uses lots of aria-label=""attributes, for accessibility reasons as far as I understood.
我习惯于title=""在我的链接/按钮/...上使用属性来详细说明它们。但aria-label=""就我所知，出于可访问性的原因，bootstrap 使用了很多属性。
So I come up to create buttons like:
所以我想出创建按钮，如：
<button
id="show-raw-result"
class="btn btn-default btn-sm btn-twigfiddle"
title="Result was not easily readable so it has been automatically cleaned up, use this button to see the result raw"
aria-label="Result was not easily readable so it has been automatically cleaned up, use this button to see the result raw">
<span class="glyphicon glyphicon-asterisk"></span> Show raw result
</button>
But copying/pasting the title to create an aria-label looks just ugly. Which one should I choose, and why?
但是复制/粘贴标题以创建 aria-label 看起来很丑陋。我应该选择哪一个，为什么？

ARIA-tags are used for disabled visitors of your site. It's very nice of Bootstrap, that they support it by default.
ARIA 标签用于您网站的残疾访问者。Bootstrap 非常好，他们默认支持它。
Accessible Rich Internet Applications (ARIA) defines ways to make Web content and Web applications (especially those developed with Ajax and JavaScript) more accessible to people with disabilities. For example, ARIA enables accessible navigation landmarks, JavaScript widgets, form hints and error messages, live content updates, and more.

To answer your question, which one you should use, use only the title-attribute. Because this attribute is used if your mouse go over the button and shows the text of titleas a tooltip. With aria-labelis not supported in this way.
要回答您的问题，您应该使用哪一个，请仅使用 -title属性。因为如果您的鼠标移到按钮上并将 的文本显示title为工具提示，则会使用此属性。随着aria-label不以这种方式支持。
