有人可以给我一些关于什么类型的值对于aria-label属性有效的示例.
解决方法
它可以是任何用于命名元素的字符串.
ARIA spec:
aria-label说：
Most host languages provide an
attribute that could be used to name
the element (e.g. the title attribute
in HTML),yet this may present a
browser tooltip. In the cases where a
visible label or visible tooltip is
undesirable,authors MAY set the
accessible name of the element using
aria-label.
