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.
The related ticket in the jQuery repository about this issue is
https://github.com/jquery/jquery/issues/2070.
This closes https://github.com/select2/select2/issues/2969.
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 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`.

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.
This closes https://github.com/select2/select2/issues/2938.
This adds `StopPropagation` modules that will stop the propagation
of the most common events from the selection and dropdown containers.
These modules work from a list of 21 common events, most of which
were stopped by default in past versions, and call `stopPropagation`
on them when they are detected at the container level.
These modules are only available in full builds of Select2.
This closes https://github.com/select2/select2/issues/2033.

This adds documentation for the `templateResult` and
`templateSelection` options. The fact that placeholders and
custom messages are templated was noted, although most people
should be using the standard `text` property that they provide
anyway. This fixes the templating link provided in the release
announcement to link to the correct location in the documentation.
This also adds support for the `templateSelection` function to
return a DocumentFragment or jQuery compatible object to be
passed back and rendered.
This closes https://github.com/select2/select2/issues/3005.
This closes https://github.com/select2/select2/issues/3019.
The `closeOnSelect` option was previously used to control whether
or not the dropdown was closed when an option was selected. This
could be simulated by triggering the `open` event after the `close`
event was received, but it makes sense to abstract it out into a
decorator.
This also adds support for not closing the dropdown when the control
key is being held. This is useful when multiple options need to be
selected in quick succession, so the dropdown does not have to be
reopened.
This also adds documentation that covers both changes.
This closes https://github.com/select2/select2/pull/2735.
This closes https://github.com/select2/select2/issues/3017.
This also fixes the case where `templateResult` does not return a
string, where it will fall back to jQuery to set the value of the
option. This allows for the `templateResult` function to return a
jQuery or DOM element that contains the templated data.
Just like with the translation methods, only strings returned from
`templateResult` will be escaped.
The old flag icons have been transferred from the old repository to
the documentation, for use in the templates. Unfortunately I cannot
find a license for them, but I suspect a license isn't actually
needed considering the state flags are public.

Select2 previously had an issue displaying the text of long values
as it was not correctly wrapping the text. This was because the
browser did not know that it couldn't wrap at whitespace, which
has been fixed.
Now Select2 should properly display an ellipsis for large text
values instead of overflowing.
This closes https://github.com/select2/select2/issues/2984.
In a single select, the search field is automatically focused when
the select is opened. This also applied to multiple selects, but
this was causing issues because the container was automatically
focused when the dropdown was closed.
This makes a change such that the search field is automatically
focused when the dropdown is closed.
This closes https://github.com/select2/select2/issues/2995.
The search box previously displayed a clear icon on the far right
side in webkit-based browsers, specifically Chrome and Safari. This
hides the clear icon in those browsers, and also fixes a slight
sizing issue, so it should no longer be displayed.
This also disables autocorrect, autocompleted, as well as a few
other automatic search corrections on the field, so mobile devices
should have a better experience.
This closes https://github.com/select2/select2/issues/3018.
This splits out the two templating functions that are referenced in
the documentation. The two functions were previously available in
the source code, but they were not named with the method names that
the documentation referred to.
This closes https://github.com/select2/select2/issues/2993.
In past versions of Select2, supplying a value less than zero to
`minimumResultsForSearch` acted the same as providing a high value,
such as `Infinity`. This corrects the regression by mapping anything
less than zero to the value `Infinity`.
This closes https://github.com/select2/select2/issues/2994.
It is assumed that DOM elements or related objects will have been
escaped before they are passed back from templating functions. As
strings are typically blinding concatenated, like in our defaults,
it makes sense to escape the markup within them.
This is related to https://github.com/select2/select2/issues/3005.
It appears as though GitHub has stopped serving the Placeholder.js
GitHub Pages site. This broke placeholder support on older versions
of IE in the documentation and broke the link we had to the
polyfill. Since the repository is still online, and the
documentation should work without an internet connection, the
JavaScript files have been pulled into the documentation folder.
Translations will now be passed through `escapeMarkup` and injected
into the results messages as HTML just like the templating options
for the the results and selections. This fixes the regression from
3.x where the old formatters always supported HTML.
This closes https://github.com/select2/select2/issues/3008.
The `allowClear` option may not work as intended if a placeholder
is not used. This is becaise the placeholder holds the value that
the `<select>` should be reset to when the `x` is hit.
An error is now properly raised in the console when Select2 detects
that the `allowClear` option is used without the `placeholder`
option.
This closes https://github.com/select2/select2/issues/3016.
