Quick review of ARIA Authoring Practices examples

Alert

https://rawgit.com/w3c/aria-practices/master/examples/alert/index.html



Comments:

   -

   Probably worth having an alternate example that uses aria-hidden to
   trigger CSS display:none becoming display:block. This should also be a
   legal way of doing alert, and it’s a pretty common way of making content
   suddenly visible.

Button

Comments:

   -

   Tabbing to button, entire button does not scroll into view (only top
   half does)
   -

   Pressing Space or Enter on button, document scrolls to top and button +
   links are scrolled out-of-view


Disclosure

Comments:

   Minor comment: is it worth putting the disclosed text in a live region
   so that it is read automatically upon expansion? We do this in the tab
   example.


Grid

Comments:

   -

   Steals Alt+left/alt+right, and probably other modified arrow keys. In
   all examples, the keyboard handler should be very careful about rejecting
   keys with modifier combinations that are not used. Also, the keys that are
   used should be consumed. The treegrid example is very careful about this.


Listbox

Comments:

   Not sure why, but NVDA reads “not selected” for items but never reads
   “selected” in both Chrome and Firefox. The experience doesn’t seem right,
   reading “checked” for selected items but “unselected” for the opposite.
   Also, the author should not need to include “checked” in the name since
   that should be read automatically, that’s what the semantics are for.
   -

   NVDA does not read that the list is multiselectable upon entry into the
   list. This should be reported to the NVDA team.
   -

   Chrome should be exposing the SELECTED state for the focused item in
   single selection lists when aria-selected is not "false"

   Get 404 errors for links to the two examples from

Radiobutton

Comments:

   Steals alt+left, alt+right as other examples do. We need to fix all the
   example to be exact with the modifier logic, so I won’t list this problem
   for each example.


Slider

https://rawgit.com/w3c/aria-practices/master/examples/slider/slider-1.html

Comments:

   -

   Does not work with Chrome. I’ve filed a bug in Chrome for this.
   -

   There are 3 valuechange events for each slider movement, which does not
   seem like the normal case, and makes it harder to use for debugging.
   However, this is not a deal-breaker or anything like that.


Progressbar

   -

   Example not present, but I suggest it should be as it’s widely useful,
   and very similar to writing a slider

Tree

   The automatic posinset/setsize is not reported in Chrome. I’ve filed an
   issue for this.
