This example should replace the "read more" link text at the end of the teaser text with the content of the h2 heading referenced by aria-labelledby. When the link text itself should be included in the label text, the ID of the link should be referenced as well in the string of IDs forming the value of the aria-labelledby attribute.įor more information on the naming hierarchy please consult the ARIA specification and the accessible name and description calculation in the HTML to Platform Accessibility APIs Implementation Guide. The specified behavior of aria-labelledby is that the associated label text is announced instead of the link text (not in addition to the link text). When applied on links, aria-labelledby can be used to identify the purpose of a link that may be readily apparent for sighted users, but less obvious for screen reader users. The label text should then be concatenated following the order of IDs in the value of the aria-labelledby attribute. Each of the text elements used must be given a unique ID which is referenced as a string of IDs ( IDREF) in the value of the aria-labelledby attribute. It is also possible to use several text elements on the page as a label for a focusable element. When associating text to a focusable element with the help of aria-labelledby, the target text element is given an ID which is referenced in the value of the aria-labelledby attribute of the focusable element. For example, a "read more." link could be associated with the text of the heading of the preceding section to make the purpose of the link unambiguous (see example 1). With the aria-labelledby attribute, authors can use a visible text element on the page as a label for a focusable element (a form control or a link). NVDA ignores labelledby on an anchor (unsuccessful implementation) Example 3: JAWS 14 in FF, IE 10 read the entire paragraph for each link which is confusing and chatty, VoiceOver for Mountain Lion in Safari 6 OK.VoiceOver for Mountain Lion in Safari 6 same as JAWS. Example 2: JAWS 14 in FF, IE 10 read the entire paragraph for each link which is confusing and chatty.Example 2 and 3 are still not sufficiently supported. Win 7, FF 13, JAWS 13 (but Example 2 has only partial/buggy support: "Sales report 2012" is read twice)ĭavid tested on Aug 25, 2013.Win XP, IE 8, NVDA 2011.3 (but Example 2 not supported).Win 7, IE9, NVDA 2012.2.1 (but Example 2 not supported).Partial support (both link text and element referenced by aria-labeledby are read):.Screen reader testing as of 22 October 2012
On focus the link text 'Read more' was announced first with the referenced aria-labelledby content announced second.
