Hi All: I have been looking at how the HTML placeholder attribute is supported by IA2.
According to the HTML accessibility API mappings at: https://www.w3.org/TR/html-aam-1.0/ The placeholder in HTML should be handled just like the aria-placeholder. According to the core api accessibility mappings http://w3c.github.io/aria/core-aam/core-aam.html The aria-placeholder is mapped to an Ia2 object attribute of placeholder. So, it sounds like the HTML placeholder should be mapped to an IA2 object attribute of placeholder. Currently Firefox seems to support the placeholder as the name of the field if there is no other name provided by the page author (from https://bugzilla.mozilla.org/show_bug.cgi?id=545817. This seems to contradict the description of aria-placeholder from the WAI-ARIA) 1.1 spec at http://rawgit.com/w3c/aria/master/aria/aria.html#aria-placeholder Says: “[ARIA 1.1] Defines a short hint (a word or short phrase) intended to aid the user with data entry when the control has no value. A hint could be a sample value or a brief description of the expected format. Authors should not use aria-placeholder instead of a label as their purposes are different: The label indicates what kind of information is expected. The placeholder text is a hint about the expected value. See related aria-labelledby and aria-label. Authors should present this hint to the user by displaying the hint text at any time the control's value is the empty string. This includes cases where the control first receives focus, and when users remove a previously-entered value. NOTE As is the case with the related HTML placeholder attribute, use of placeholder text as a replacement for a displayed label can reduce the accessibility and usability of the control for a range of users including older users and users with cognitive, mobility, fine motor skill or vision impairments. While the hint given by the control's label is shown at all times, the short hint given in the placeholder attribute is only shown before the user enters a value. Furthermore, placeholder text may be mistaken for a pre-filled value, and as commonly implemented the default color of the placeholder text provides insufficient contrast and the lack of a separate visible label reduces the size of the hit region available for setting focus on the control.” I am suggesting that we all agree to present the HTML placeholder just like the aria-placeholder using the IA2 object attribute of placeholder? This provides the most flexibility for screenreaders to present the placeholder information anyway they see fit. Using the placeholder as the name is not as flexible as the screenreader cannot distinguish between the placeholder and the label in this case. What does everyone think?
