Quickly navigating via the keyboard to an autocomplete
element and hitting down would result in the selections
being displayed and then quickly removed. This has now
been fixed.
Fixes 3 problems with deselecting items in an autocomplete field:
1. Keep track of whether items were in the offical suggestion list, or are newly created
tags and remove the "newly created tags" from the suggestion list when they are
deselected
2. Change the aria-role for the selected items list when items cannot be deselected (and
do not treat it like a multiselect list).
3. When leaving and returning focus to the selected items list, remember the last
active-descendant.
When nodes are added to the dom, they may need to be re-processed by a JS based
filter. To do this we need to trigger the legacy YUI event filter-content-updated.
To make this easier I added some wrappers to template that will insert the node, run any
JS and trigger the event.
I also changed existing yui code to call the amd function to trigger the event. This way
all jquery and yui listeners will always be notified.
Now the db/service.php array can contain these extra keys to provide information
on how a webservice may be called:
'ajax' => true (Default is false)
Replaces the xx_is_allowed_from_ajax callback.
'loginrequired' => false (Default is true)
Means that this webservice can be called through lib/ajax/service-nosession.php
which sets NO_MOODLE_COOKIES to true (faster). This is only safe for webservices returning
static public data (e.g. get_string).
The first ajax load fetches the template and puts it in localstorage + a js var
The second load gets it from local storage, but does not put it in the js var.
The pix_icon helper expects it to be in the js var always.
This needs to be done before we can expose any webservices that
change state, or return private info to ajax (to prevent CSRF).
Currently there are no webservices exposed to ajax that meet these
criteria - so this issue is to prevent future security issues.
This is a new script that can call any function in the built-in AJAX webservice. This is
a new system service that is added at install time (like the mobile webservice). It has no
protocols added to it, but it accessible by a new ajax script /lib/ajax/service.php.
Requests and responses to the script are required to be in json format, and multiple functions can
be called in a single request.
