可访问性:aria-haspopup 可以用来做什么? [英] Accessibility: what can aria-haspopup be used for?

问题描述

我确信aria-haspopup 适用于子菜单(例如弹出式上下文菜单或子级菜单).它用在 jQuery UI Selectmenu 上，也用在这个 <一个 href="https://stackoverflow.com/questions/12279113/recommended-wai-aria-implementation-for-navigation-bar-menu">很好的例子.

I have it on good authority that aria-haspopup is appropriate for sub-menus (such as a popup context menu or sub-level menu). It's used on jQuery UI Selectmenu and also used in this great example.

我无法确定的是 aria-haspopup 是否适用于以下 2 个示例:

What I've not been able to find out is whether aria-haspopup is applicable in the following 2 examples:

• 信息弹出框，例如引导程序 - 用于上下文信息，但不包含任何链接
• 弹出式浏览器窗口 - 例如与 target="_blank"
的链接

• Informational popovers such as Bootstrap's - used for contextual information, but not containing any links
• Pop-up browser windows - e.g. links with target="_blank"

aria-haspopup 在这些情况下是否合适?如果没有，是否应该使用 ARIA 属性?

Is aria-haspopup appropriate in those situations? If not, are there ARIA attributes that should be used instead?

推荐答案

正式它应该只用于菜单或子菜单，来自 ARIA 规范 1.0:

Officially it should be used only for menus or sub-menus, from the ARIA spec 1.0:

表示该元素具有弹出上下文菜单或子级菜单.

Indicates that the element has a popup context menu or sub-level menu.

Whatsock 风格指南在模态"部分对此进行了介绍:

The Whatsock style guide covers this under the 'modals' section:

通过向触发元素添加属性 aria-haspopup="true" 来通知屏幕阅读器用户附加了弹出窗口"似乎是个好主意，但这不是一个好主意....简而言之，除非您正在触发菜单，否则不要使用 aria-haspopup.

It might sound like a good idea to notify screen reader users that a 'Popup' is attached by adding the attribute aria-haspopup="true" to the triggering element, but this is not a good idea. ... In short, don't use aria-haspopup unless you are triggering a menu.

有一些关于扩展含义的讨论 在未来的修订中，但目前假设它用于菜单.

There is some discussion about expanding the meaning in future revisions, but for the moment assume it is for menus.

我给出了关于 Bootstrap 工具提示的答案 应该有帮助.

I gave an answer about Bootstrap's tooltips which should help.

对于弹出式浏览器窗口，无论如何都是由屏幕阅读器宣布的，不需要额外的标记.(注意:它有助于为屏幕放大镜用户包含一个新窗口的视觉指示器.)

For pop-up browser windows, those are announced by screen readers anyway, no extra markup is needed. (NB: It helps to include a visual indicator of a new window for screen magnifier users.)
