We’ve seen in research a user getting stuck playing with the
scheduler. They picked a day, but then didn’t want to choose one of the
options for that day. There’s no way to do this except pick a day and
then un-pick it.
What they ended up doing was clicking the grey back button, which took
them back to the previous page, making them upload their file again.
This commit adds a ‘back’ link for the scheduler. ‘Back’ seems like
sensible naming because that’s the thing that the user tried to click,
and the UI of a link matches the thing they clicked to get into this
situation.
Not sure what about the new radios is causing this, but they no longer
expand the size of the container, causing an overlap.
The fixed height was originally for performance reasons, but removing
it doesn’t seem to cause the page to jump around on load, so I think
it’s OK.
The visual appearance of radio and checkbox form inputs changed in
GOV.UK Elements here:
https://github.com/alphagov/govuk_elements/pull/296
This was subsequently reimplemented with different markup and no
Javascript here:
https://github.com/alphagov/govuk_elements/pull/406
This has meant making the following changes to our app:
- changing the markup in our radio/checkbox macros to match the example
markup given by GOV.UK Elements
- removing the previous Javascript file because it’s no longer needed to
make the radios appear visual selected
- making the buttons on the scheduled job picker look like links,
because the grey button style looked weird with the new radio buttons
Fixes the height of the component until it’s loaded so that it doesn’t
causes the page to reflow while it’s rendering the buttons.
Stops the options being shown and then immediately hiding on initial
page load.
The options for scheduling a job by time should be grouped by day,
because a long list of 96 options is not very usable.
On the server side, this commit generates label for the next 4 days in
a friendly format (ie today/tomorrow/Sunday/Monday)
The Javascript component for choosing a time was built in a kind of
old-school jQuery way, where it manipulated the elements on the page.
The complexity of introducing groups of options was just too much for
this pattern, because it involves storing a lot of state in the DOM.
This commit completely rewrites the JS to:
- read the initial options and groups from the HTML and store them
in the object
- use Hogan to completely re-render the UI from a series of Mustache
templates, each of which represents a state of the UI and takes the
inital options and groups
- filter the choices to show when the today/tomorrow/… buttons are
clicked
Users need to pick a time in the next 24hrs, or send a file immediately.
Rationale for this is a bit lost in time-before-holiday, but generally:
‘Now’ and ‘later’ as the inital choices makes it really clear what
this feature is about conceptually.
The choice of times is absolute, eg ‘1pm’ not ‘in 3 hours’
