I updated the regression tests to fix the SPACE key issue in Issue #1358

zcorpan · 2020-04-03T13:04:10Z

Part of the regression test for the date picker is very slow to run. It's focusing each cell with half a second delay between each step. Do you know why it's slow?

$ npm run regression -- --match "*datepicker*"

> aria-practices@0.0.0 regression /Users/zcorpan/git/w3c/aria-practices
> ava --timeout=1m "--match" "*datepicker*"



  43 tests passed
  2 known failures

  dialog-modal_datepicker › dialog-modal/datepicker-dialog.html [data-test-id="month-year-button-space-return"]: SPACE to buttons change calendar and date in focus
  dialog-modal_datepicker › dialog-modal/datepicker-dialog.html [data-test-id="grid-space-return"]: SPACE or RETURN selects date in focus

Are the known failures intended to be failures still?

Should all Key.SPACEs be replaced with ' '? Maybe we can lint it also?

Sounds like a good idea.

@zcorpan

I just did some testing and we can only do this when an keyboard event handler is associated with a button. So I think we should only use " " technique when needed and use Key.SPACE when it works correctly,

Improved high contrast support

The focus indicator is a 2px white border instead of a 1px white border. Could it be a different color, or more visible in some other way?

jongund · 2020-04-03T16:58:10Z

@zcorpan Your right there is not much difference, I am going to change the border to be dashed to see if it stands out more.

jongund · 2020-04-03T18:21:31Z

@zcorpan I made some changes to focus styling and aria-selected styling that helps in high contrast, please review.

I made some updates for high contrast support for dates and buttons in the dialog, can you review and comment on the changes.

…priate.

mcking65 · 2020-07-17T06:50:25Z

@jongund, I just wrapped up my editorial review and pushed some revisions. While reviewing, I found 2 more things we need to change before requesting final reviews.

Remove aria-autocomplete from the input. It is a normal textbox, not a combobox, so we shouldn't specify autocomplete none.
Remove support for down arrow opening the dialog when focus is on the button; modify script, test, and documentation accordingly. The button is a normal button, not a menu button, so it should not support activation with down arrow.

jongund · 2020-07-17T14:17:01Z

@mcking65
Is the reason it is not to use the menu button pattern is because it opens a dialog and not a menu?

jongund · 2020-07-17T14:41:15Z

@mcking65
The date picker dialog has been updated by removing the autocomplete attribute and the down arrow now does not open the dialog.

Yes, exactly.

mcking65

Final editorial review complete: The documentation of the example is consistent with editorial guidelines, the relevant design patterns, and the ARIA spec, and it pmatches what is implemented in the code.

I also tested thoroughly with JAWS and NVDA in Chrome. As expected, based on our testing of the date picker combobox example, there are improvements needed by screen reader developers. There are deficiencies in screen reader support for abbr on TH when in a grid. And, the way NVDA reads a grid makes understanding a grid of numbers difficult.

carmacleod · 2020-07-21T17:19:49Z

The calendar button takes focus on page load. Do we want that? I found it a bit surprising.

carmacleod · 2020-07-21T17:28:42Z

In the dialog, shortcut keys are assigned to the additional buttons for changing the month and year displayed in the calendar.

How can the user discover the shortcut keys? Should we have tooltips (@smhigley 😄 ?) on the change month/year buttons?

Keyboard help is displayed at the bottom of the dialog.

Or maybe the change month/year shortcuts can be added to the keyboard help text?
i.e. the keyboard help text currently says:

Cursor keys can navigate dates

maybe change it to:

Cursor keys can navigate dates. PageUp/PageDown changes month. Shift+PageUp/PageDown changes year.

Come to think of it, should we change the word "Cursor" to "Arrow"? i.e. maybe some folks don't know what "Cursor" keys are?
So maybe:

Arrow keys navigate dates. PageUp/PageDown changes month. Shift+PageUp/PageDown changes year.

Can anyone think of a more concise, but still understandable, way to write that sentence?

carmacleod · 2020-07-21T17:48:34Z

If the user only types a 2-digit year, what do we want to happen?
Currently, the calendar opens in the 1900's.
For example, 5/7/09 opens to May 7th, 1909.
I think we should at least change that to open May 7th, 2009, because now that we are in the 2000's, people think of '09 meaning 2009.

smhigley · 2020-07-21T17:54:38Z

@carmacleod could we open a separate issue for those bugs? I'm in favor of keeping this PR to the changes Jon already outlined & merging it (and those changes look good to me, fwiw). Then we can have additional smaller PRs for each other bug :).

carmacleod · 2020-07-21T18:02:03Z

@smhigley I'm happy to open new issues for the shortcuts and the 2-digit year. But the calendar button taking focus on page load is being introduced by this PR (here's the released example), so I think we should fix that one before it goes in?
It seems to be because the DatePickerDialog is created on page load and then "this.close()" is called, but that puts focus on the button. So just needs a tiny refactor to call the "hide the dialog" code separately from the "focus the button" code.

jongund · 2020-07-21T19:52:56Z

@carmacleod
@smhigley
I fixed the focus on button when page loads and also added a feature for a 2 digit date to default to 20xx.
Please test when you have a chance.
Thank you for the feedback.

Thanks, @jongund.
Looks good!
