This fixes an issue where the dropdown would not automatically
open when something was typed in the search box on a multiple
select. This was most noticeable when the dropdown closed and
the search box was focused and the user started to type, as the
text would appear in the search box, queries would be sent out to
retrieve results, but the dropdown would not be opened to display
the results.
This also fixes an issue introduced in a recent commit where search
queries would be sent out twice on modern browsers that supported
both the `keyup` and `input` event. The `keyup` event is now
properly debounced for these browsers and the queries are only
going out once.
This closes https://github.com/select2/select2/issues/3036.
Previously, when in results the enter key would select items that
were highlighted if they were not already selected. In the case of
a select where multiple items could be selected, pressing enter
when highlighting a selected item would also allow it to be
unselected. While this seems intuitive for accessibility purposes,
the enter button essentially working as a toggle, it caused some
really strange behavior.
- If the enter button was held down, all previously selected items
would be unselected.
- The enter button did not work the same across both single and
multiple selects.
After listening to user feedback, I have decided to remove the
"enter as toggle" functionality from Select2 and have gone back to
just having the enter button select items. This means that instead
of unselected items that are already selected and highlighted,
Select2 will just close the dropdown. This is the same as what
Select2 would previously do for single selects, so the keyboard
functionality is now the same across both.
Because this removed the only easy way to unselect items in the
dropdown using the keyboard, we had to maintain the toggle
functionality. We decided to implement the toggle functionality
on the CTRL + Space keybinding, which is in line with other
applications. Now when pressing CTRL + Space at the same time in
the dropdown, the highlighted result will behave the same as if the
mouse selected it, which will toggle the current item in multiple
select mode and close the dropdown in single select mode.
This is the same keybinding that Windows Explorer [1] and GTK [2]
use for toggling the current selection, which was why it was picked.
This also fixes an issue where keyboard focus would be lost once an
item was unselected from the results. This was due to a bug in the
CloseOnSelect module that would only automatically close the
dropdown when an item was selected, but not when an item was
unselected. Now the dropdown will be closed automatically when an
item is unselected, which will also cause the selection (and
eventually the search) to be focused.
This fixes two issues described in
https://github.com/select2/select2/issues/3036#issuecomment-76321411.

This fixes an issue where most keys would not trigger the search
in Firefox for Android. There were only a few keys which would
trigger `keyup`, such as space and enter (the search icon), but
they were not consistent. We know that they were being triggered
though, as you could type "new " (note the space) and it would
trigger a search, giving us all states that started with "new".
The problem is that Firefox for Android does not consistently
trigger `keyup` and `keydown` events when a keyboard is used. To
work around the issue, we are now using the `input` event in
replacement of the `keyup` event, which was used to trigger the
search. While this is not an actual `KeyboardEvent` in Chrome, and
lacks some of the important metadata such as `which`/`key` in
Firefox, it works for our implementation.
As the `input` event is not supported in older browsers, such as
those before Internet Explorer 9, we have to listen for both the
old `keyup` event and the new `input` event. As the `input` event
is always triggered before the `keyup` event, we unbind the `keyup`
event automatically to prevent searches from being triggered twice.
This solution was discovered in a blog post by Mathias Bynens at
https://mathiasbynens.be/notes/oninput.
**Note:** The ability to backspace in a blank text field on multiple
selects in order to remove the last selected item does not work in
Firefox for Android because the `keydown` event does not trigger
when the text field is empty. Users can still use the "x" icon
provided at the start of every selected option to achieve the same
effect.
This closes https://github.com/select2/select2/issues/2997.
This also fixes a possible issue where the `< 0` fallback would
not be used because the `minimumResultsForSearch` check would
always return false and never load in the module.
This closes https://github.com/select2/select2/pull/3077.
This fixes the fallback path for the `data-ajax-url` attribute on
elements. As this attribute was previously supported in Select2,
the attribute has been migrated to the new, nested format of the
url and triggers a deprecation warning when it is used. Because
of a fix to the `data-*` attribute parsing made in a9f6d64 that
allowed for nested attributes to be parsed correctly in modern
browsers under jQuery 1.x, the deprecation warning would be
triggered but the attribute would no longer actually be used.
This also fixes some of the `.data` calls to use the camel cased
version of the key instead of the dashed version, which is the
preferred key and will be enforced in future versions of jQuery
as the only way to access data attributes.
Now in situations where the `dataset` attribute is used by Select2,
it combines the results of both `$e.data()` and `e.dataset` when
generating the object containing all of the options. This will
the `dataset` fix to still be used, while also still relying on
jQuery to do additional parsing on any options that it can.
The `dataset` fix is now only used on jQuery 1.x, as that is the
only version of jQuery affected by the dash issue. This is done
using version number parsing on the `$.fn.jquery` property that is
defined by jQuery. As this property is not defined in Zepto and
many other jQuery compatible checks, we only include the fallback
if the property is available. This assumes that any jQuery
compatible libraries that are in use will not include the same dash
issue, which we believe is a safe assumption given that it did not
match the HTML `dataset` specification.
This also adds a few tests to ensure that the deprecated attributes
still continue to function.
This closes https://github.com/select2/select2/issues/3086.
This adds basic documentation explaining that there are compatibility
decorators for `<input type="text" />` support. This is not fully
compatible with all features and requires the use of an external
adapter like the `ArrayAdapter` or `AjaxAdapter` to provide a
reasonable way to query results.
This also triggers a warning if the adapter is used with a hidden
input, as the degraded functionality when there is no JavaScript
support should be discouraged.
This adds backwards compatibility back into Select2 for `<input />`
tags. The compatibility modules are only available in the full
version and will trigger a warning if a hidden input is being used.
With the new decorator, Select2 should support the basic operations
that it previously did, with the exception of completely overriding
the internal objects. As we no longer expose `data` as a writable
method, it is no longer possible to completely override the selected
data. The state is still managed internally, but in order to prevent
data corruption issues in the past, it is not exposed to the public.
Some small changes needed to be made to how Select2 was dynamically
generating new `<option>` tags, so now a method is called that can
be overridden. In the case of the new decorator, this method is
intercepted and handled without having to actually place the
`<option>` tags into the DOM.
The decorator is applied after all of the other defaults, as the
defaults are not given the current element.
There has only been limited testing with this decorator, primarily
using the `data` and `placeholder` options.
This closes https://github.com/select2/select2/issues/3022.
The documentation README was previously intended to be read from
the documentation repository, not from the source repository.
This had the potential to give off the impression that documentation
pull requests were not allowed, when exactly the opposite is the
case. The README has been improved to make it more clear how to
contribute pull requests to update the documentation.

As we have established already, jQuery 1.x does not correctly handle
`data-*` attributes where there are multiple dashes. This makes it
so we can still handle nested options when working with jQuery 1.x
by using the `.dataset` option that is supported by all major
browsers as well as IE 11+.
Browser support tables for the `.dataset` attributes can be found at
http://caniuse.com/dataset
A notice was already added to the documentation about this in
caeb0ec9b7.

We are special casing Opera 12 as well as the latest Opera version
because Opera 12 was the last release because Opera switched to the
Webkit rendering engine.
Now the focus of the selection container is correctly monitored so
there is a consistent 1px black border on the default theme whenever
it is focused. This requires `focusin`/`focusout` support, which is
supported by all major browsers except for Firefox. In Firefox, the
old focus appearance is still consistent and has not been broken
by this update.
The key handling has also been improved such that some of the logic
detection that was previously done within the search handlers for
multiple select searches is now pushed back to the base selection.
This closes https://github.com/select2/select2/issues/2995.
Previously Select2 would assume that the tab index for the
`<select>` was `0`, which is the browser default. Now Select2 will
clone the tab index from the original element, and correctly restore
it when it is destroyed or disabled/enabled.
This closes https://github.com/select2/select2/issues/3031.
This groups tests into common HTML files so they can be run more
quickly. This also reduces the number of Sauce Labs instances that
have to be run, as one instance was previously spun up for each
file.
There were a few undefined variables being referenced within the
Select2 code. The JSHint configuration has been modified to fail
if there are undefined variables being referenced, including any
global variables.
There is an exception that is being made for the jQuery shim, as it
must try to find the global jQuery references.
An exception is made for the test helpers, as the SauceLabs reporting
variables are not camelCase, and would normally trigger warnings.
This closes https://github.com/select2/select2/pull/3028.
This sets up Select2 to be able to run tests on the SauceLabs
environment. This will allow us to run the tests on different
browsers in the future, though at the moment we need to start
combining test files.
This required adding a snippet of code for reporting QUnit test
results to SauceLabs within the global test helper file.
The tests currently cannot be run on IE 8 because all of the tests
are using jQuery 2.x, which is not compatible.
This copies the `title` attribute of `<option>` and `<optgroup>`
tags to the `title` attribute of the options within the results
list and the selection when it is rendered.
For single selections, the `text` property on the data objects will
be used if the `title` attribute is not present, which will allow
for long names to still be viewable if they overflow the selection
container.
This also fixes a potential issue in browsers that did not support
the non-standard `innerText` property on DOM nodes. As the
`textContent` property is the standard, and it is supported on
IE 9+, we try to set that before falling back to `innerText`.
This closes https://github.com/select2/select2/issues/2530.
This closes https://github.com/select2/select2/pull/2889.
In the past, `select2("data")` allowed you to retrieve the currently
selected data objects. Read-only support has been added back for
this, which maps to the `current` method of the data adapter. This
will only work for data adapters which allow for the synchronous
retrieval of the current data, which is the case for all of the
default data adapters.
You could also previously overwrite the currently selected data
objects by passing in an argument to `select2("data")`. As this
dealt directly with the internals, and required a considerable
amount of work to synchronize it, it has been removed. A warning
will now be triggered if the method is called with additional
elements, and the `val` method should be used instead.
