html"hidden"属性是布尔值，不需要设置值.仅仅存在就足够了.

隐藏的信息"属性如何?仅仅存在就足够了吗?还是需要设置值为"true"?

What about the "aria-hidden" attribute? Is it's mere presence sufficient? Or does it require the value "true" to be set?

推荐答案

aria-hidden必须具有true | false的值.但是请注意，如果使用hidden属性或使用CSS visibility:none或display:hidden，则不需要 .后三种隐藏方式中的所有三种也将在屏幕阅读器中隐藏该元素.如果要在屏幕上隐藏一些要从屏幕阅读器隐藏的东西，例如装饰性元素，不会增加页面的含义，则只需要aria-hidden="true".

aria-hidden must have a value of true|false. Note, however, that aria-hidden is not needed if you are using the hidden attribute or if you are using CSS visibility:none or display:hidden. All three of these latter three ways to hide will also hide the element from a screen reader. You only need aria-hidden="true" if there's something on the display that you want to hide from a screen reader, such as a decorative element that does not add meaning to the page.

如果要通过将对象的字体大小设置为0或使用剪切矩形来隐藏"对象，或者使用x或y将元素推"出屏幕，则将 >需要在该元素上设置aria-hidden="true"，因为以前的技术只能在视觉上隐藏该元素，而不能真正地隐藏该元素.

If you are "hiding" an object by setting its font size to 0 or using a clipping rectangle or "pushing" the element off the screen with x or y, then you will need to set aria-hidden="true" on that element because the former techniques are only visually hiding the element and not truly hiding the element.
