This adds detailed docs explaining how you can convert the old
implementations of `query` and `initSelection` into a custom data
adapter using the `current` and `query` methods provided there.
Examples are included that should make it considerably easier to
handle.
This adds the `select` and `unselect` events so users can still
hook into them from their jQuery plugins.
This also modifies the core `trigger` to fire pre-events that can
be canceled for the `open`, `close`, `select`, and `unselect`
events. Users implementing these events who need to handle cases
where the event has been prevented should check `args.prevented`,
where `args` is the object that was included for arguments when
triggering the internal event.
In past versions of Select2, the `width` option could be used to
tell Select2 how to determine the width of the container generated
by Select2.
**Breaking change:** The default value for the `width` option has
been changed from `copy` to `resolve.`
**Breaking change:** The old option called `copy` has been renamed
to `style` to better reflect what the width is generated from.
This fixes https://github.com/select2/select2/pull/2090.
This fixes https://github.com/select2/select2/issues/2911.
Tagging should be demonstrated using the multiple select, as that
is where it really shines. It's also how we used to demonstrate it.
This closes https://github.com/select2/select2/issues/2901.
Now Select2 can fire jQuery events that will match the corresponding
internal events. The `open` and `close` events are now publicly
accessible.
The selection adapter was chosen because it is the least likely to
be moved, but handles the most common events. This `EventRelay`
decorator should theoretically be able to decorate any of the
adapters, as they all have the `bind` method that it needs.
The star event will allow us to relay any custom events as well as
the ones used internally by Select2. This also makes it much
easier to start triggering events in general, as we don't need to
relay it in the core anymore.
A module has been created for the jQuery-facing events, and the
release announcement has been updated to mention the event name
changes.
This also adds some documentation about the public events.
There was a plan to universally use an array as the return from
query methods, but now that we've realized pagination and extra
things are impossible without it, we're going back to the return
object. Anyone looking to migrate their data should be returning
an object with the key `results` containing what they previously
returned.
This should fix https://github.com/select2/select2/issues/2898
I'm still not quite sure how this should be handled for the general
case, but for the special case we have this for infinite scrolling,
only on AJAX data.
The documentation for templates still needs to be created.
A warning is now generated in the console for applications using
the previous data attributes that have been migrated.
alt-down/up is the standard way of opening a select when using a
screen reader. This also fixes the gradient in IE, so now it
displays the right colors. Also added a note about Placeholders.js,
so the placeholders on multi-select boxes will work in IE 9 and
below.
Added a disabled state for Select2. This will correctly listen to
property changes (so when the disabled property is changed) and
update the state of Select2 to reflect it.
Added a utility function to find a method to a different context.
With the recent changes to how Select2 works internally, this really
isn't needed. This has been added to make the migration path
easier, and it just internally calls `val` on the underlying select
element. The only difference is that the `val` function will now
convert any non-string elements to strings.
The second argument (`triggerChange`) has not been migrated, as
Select2 now internally relies on the `change` event.
**Note:** As the old `initSelection` method has not been migrated,
it is not possible to set the `val` on remote data sources where
the value has not previously been selected.
`dropdownParent` controls the location of the dropdown when it is
automatically added to the DOM. By default, this is the body
element but it can be modified based on where the user needs it.
This adds a dictionary for converting diacritics to a normalized
representation. This dictionary is used in the default matcher.
The code for stripping the diacritics was pulled from the current
implementation in Select2 3.x.
Now when searching, a loading message is prepended to the top of
the results. This replaces the old spinner image and allows for it
to be translated across different languages.
The loading message can be styled differently and is passed
through the results formatters.
Now the options are mostly generated by hand before being passed
off to jQuery for templating. This fixes much of the speed issues
we had when they were entirely being generated through jQuery.
