This adds a broken test that demonstrates the issue seen in
https://github.com/select2/select2/issues/3990 where existing selected
options are being reset once Select2 is initialized. This issue cannot
be reproduced on the options page [1] because the issue only appear to
happen if the selected option is not the first one in the list of
possible options.

This fixes the two failing assertions that only triggered in IE 9 (no
other versions) and Firefox. Both of them were caused by the offset for
the dropdown including a constant extra amount, what appeared to be
related to the size of the container if it actually had content. This
was not consistent in browsers, so now we are forcing there to be a
small amount of content within the container and then calculating the
expected offset based on that height.
There was a commit that landed in 4.0.1 that fixed positioning for
non-static elements, which are commonly used for the custom
`dropdownParent` option, but broke positioning for statically positioned
elements, commonly used in almost every other case. That commit was
c9216b4b96
This fixes the positioning issues caused by that commit by properly
calculating the offsets for statically positioned parents. Statically
positioned parents are unique, because the offset for the dropdown must
be calculated based on the closest element that is non-statically
positioned. Otherwise, the offset for any statically positioned parent
other than the body will be considerably higher than it should be,
resulting in the dropdown being offset by a large amount.
The offset parent for the body element is the html element, which is why
this works for both the body element and any custom parents for the
dropdown. This would not be needed if the parent wasn't customizable (as
seen in Select2 3.x) because you will never need to offset the body
element if it is statically positioned, because the html element almost
never has an offset.
This also fixes JSHint issues within the tests added in the last commit.

This adds a regression test that verifies the problem with positioning
the dropdown when the parent is a statically positioned element that
still has an offset. This could typically be seen if the body element
has an offset, which unfortunately it almost always does because of the
default user stylesheet in browsers. This was not caught during
pre-release testing because all of the test pages reset the margins and
padding on the body element.
This regression test verifies that the offsets that should be set for
the dropdown are calculated correctly. These were surprisingly difficult
to do because of how the offset is calculated using different
positioning techniques.
These tests are for https://github.com/select2/select2/issues/3970
These tests should fail because a selection can be removed even
though the container is disabled. This is because the only thing
preventing selections from being removed was the CSS which hid the
remove buttons when the container was disabled.
This adds the test that ensures that the search focus is still
focused, even after the selection is updated (for whatever reason).
Note that we are not triggering the `change` event here, and are
instead just re-calling `update` on the selection adapter. This is
because we do not bind the `change` event in tests, so the selection
is never re-rendered and the tests will pass. The `update` method
is triggered during the `change` cycle anyway, so this has the
same effect while supporting cases where the selection is re-rendered
without the selected values changing.
The old functionality where classes were directly copied to the
container can be done by setting `dropdownCssClass: ':all:'` when
initializing Select2.
This closes https://github.com/select2/select2/issues/2879.
This finally fixes and adds some integration tests to make sure
that `select2('data')` works as we are expecting. This also adds
tests for `select2('val')` and fixes undefined variable issues
that were spotted because of these tests.
We also no longer date stamp distribution builds.
This closes https://github.com/select2/select2/issues/3104.
The nested data attributes are only supported on jQuery 2.x or
browsers which support the `dataset` attributes on DOM elements.
In order to prevent test failures, and because tests cannot yet
be skipped conditionally, we just cut the test early.
As jQuery 1.7.2 is the lowest version of jQuery supported by Select2,
it makes sense to run the tests on it. For the most part, we can
assume that the newer versions of Select2 are backwards compatible
enough such that this isn't an issue.
The recommended version of jQuery to use is the latest though, which
is why the jQuery file is only included in the tests.
This revealed a few issues with our data fallbacks and `.append`
functionality that was introduced in jQuery 1.8.
This strips whitespace in tags by default, so multiple tags cannot
be created with only whitespace as the difference in the id.
A test has been added to ensure that this remains fixed in the future.
This closes https://github.com/select2/select2/issues/3076.
This fixes an issue when using a `<select>` where the elements were
created with XHTML-encoded characters to prevent any injection, as
they would be double-encoded and display incorrectly.
When using a `<select>`, we can assume that the data has already
been encoded because any XSS will have already run before we get to
it. Because of this, we can just use `.text()` instead of `.html()`
to avoid any issues.
This also includes a test to ensure that this does not become an
issue in the future.
This closes https://github.com/select2/select2/issues/3115.
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.
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.
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 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.

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.
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.
This is needed to escape any bad markup that is passed through
user-entered data. Users can prevent their markup from being
escaped by using a no-op `escapeMarkup` function.
This closes https://github.com/select2/select2/issues/2990.
Now we are using `jQuery.noConflict()` in tests, so it should be
slightly easier to detect when this happens next time. Tests just
need to be written for the component.
This closes https://github.com/select2/select2/issues/2985.
This adds a check that triggers an error if Select2 was not able
to detect a copy of jQuery on the page. This should help users when
they are setting up Select2.
**Breaking change:** The full build no longer includes jQuery.
Previously, the full build included all requirements for Select2,
including jQuery, which meant that anyone looking for the optional
requirements had to possibly include multiple versions of jQuery
on their page. This means that anyone requiring Select2 to also
bundle jQuery will now need to include jQuery on their pages
alongside Select2. A copy of jQuery is included in the repository.
**Breaking change:** The AMD build of Select2 will now correctly
wrap the code in a `define` block. It will still create the named
blocks inside of the code, which should be valid in most AMD build
systems, so now Select2 is compatible with cases where the file
does not have the same name as the Select2 module name.
**Breaking change:** Select2 will re-use the AMD methods if they
are available on the page, but it will not longer leak the included
AMD loader to the global scope. The AMD methods will still be
available on the `jQuery.fn.select2.amd` namespace.
The `mock.js` test file has been renamed to `helpers.js` and will
handle the escalation of the `require` and `define` variables to
the global scope. It should be included in all test files, or the
tests will fail.
This closes https://github.com/select2/select2/issues/2946.
In the past, Select2 triggered the `select2-clearing` event when
clearing the placeholder. This has been switched to the `unselect`
event which is now triggered whenever the placeholder is cleared.
The placeholder can also be prevented if the `unselecting` event
is prevented.
This will also trigger the event when deleting every option from
the multiple select, so it is possible for the `unselecting` event
to be triggered multiple times when clearing a multiple select.
This adds tests to ensure that the `allowClear` option always works.
This closes https://github.com/select2/select2/issues/2954.
This also adds more documentation and corrects the release notes
for these breaking changes. These modules will now only be included
in the full builds of Select2, which has been noted in a few places.
This adds basic tests to ensure that the selection is accessible by
all users. This checks for common attributes, ensuring that the
container is always keyboard accessible and follows ARIA guidelines.
This also changes the base selection to create a common element so
we don't need to repeat attributes and such across multiple selection
containers.
This adds backwards compatibility with the `query` option so it
automatically patches the `DataAdapter.query` function. The only
major difference between the methods is the call signature, which
has now moved the callback out of the parameters and into the second
argument.
This also adds tests that verify that the old query functions should
work as expected.
Now if the old `initSelection` method is used, a warning will be
triggered in the console informing the user that it has now been
changed to `DataAdapter.current`, and they should create a custom
data adapter instead. We will still only call `initSelection` once,
and then default back to the old data adapter for calls after that.
This allows for mostly transparent support between versions.
This adds tests to ensure that `initSelection` operates the same as
it previously did, but now patches the `current` method of the
default data adapter.
`selectOnClose` is a new option which works very much like the old
`selectOnBlur` option. When the `close` event is triggered, the
highlighted result is automatically selected. This is useful for
single selects, which is where it is designed to be used, but it
can also be used on multiple selects.
This also adds tests to verify that this works in the future.
During the creation of the test, we noticed that we were missing a
mock container that could be used for triggering events. One was
created and a general mock JS file was created to hold any future
mocks for tests.
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.
This adds a test that makes sure that the inline data attribute
overrides the options that are passed in during initialization.
This also adds a test for the `createTag` option, which is used
when tagging.
While deep nesting will not work on a standard `<select>`, we can
emulate it through data objects still, and just handle the display
of the data in the results.
This also means that the horrific deep-nested CSS is back to handle
the padding. I hope that will get fixed over time.
This also fixes one of the performance issues with adding array
data, as options are added at the very end instead of one by one.
Also pull the logic for automatically closing the dropdown into the
dropdown adapter, taking it out of the core.
The `selected` and `unselected` events are now `select` and
`unselect`, which is what many of the other adapters were expecting
them to be.
Some tests for placeholders have been added.
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
Now that the data objects have the `element` property, we can test
to make sure it's a DOM element and then use it for selecting the
option. This allows us to select multiple options with the same id,
as well as handle cases where that is already happening.
You cannot use `$e.val()` to select two options with the same id,
as jQuery will reject it, but you can set the second option to
`.selected = true`, which is supported.
This adds a search box to the main container for multiple select
boxes, similar to the what the old version had. This can still be
swapped out such that the search box displays above the results
like it previously did.
The placeholder for multiple selects will also now use the input
attribute of the search box instead of generating a custom element.
This also changes the selector for the search container to
`.select2-search`, which is consistent with the old class and
reduces the complexity of the selectors.
This fixes an issue with how decorators worked, where the constructor
from the parent class would clobber the custom constructor that is
generated for the new decorated class. This has been fixed by
excluding the constructor from the list of fields which are
transferred when decorating classes.
This improves the speeds of creating the `<option>` tags for array
data. By creating the HTML ahead of time and putting it into an
`<option>` element before passing it to jQuery, it cuts down on the
time it takes for jQuery to process the HTML string and convert it
into DOM elements. This proved to be incredibly slow.
This also changes the `item` function to return early when the
data exists. The `$e.data` call has also been switched to a
`$.data` call, which doesn't need to check the DOM to see if the
data attributes already exist. This cuts down on a bit of wasted
time, as the `data` key should never be present in the DOM, and it
should be ignored if it is.
This converts individual objects passed in through the `array`
parameter to `<option>` tags when Select2 is initialized. This
removes a lot of duplicate code from the `ArrayAdapter`, and keeps
everything closer to the native `<select>` element.
This introduces a breaking change from previous versions of Select2,
where the initial value for array data was blank, even if a blank
option was not present in the original array of objects. Now the
first object passed in will be selected by default, following the
behavior of a standard `<select>` element.
This breaking change does not affect `<select multiple="multiple">`
elements, which by default have no selection.
When using array data, and an option is selected, the data that is
attached to the DOM element will be run through `item` and should
have any private, automatically generated attributes added and
merged with it.
We should only be checking the option values that matter, such as
`id` and `text`, instead of checking all of the option values. This
will prevent unexpected breaking when new properties are added to
the options.
Existing properties should be covered by tests to avoid regressions.
We have to enforce ids being strings as the values of options within
a select will always be an id. This fixes an issue that we had with
array selections not being highlighted in the results.
This adds decorator support in a very basic way, but enough that
it doesn't take a lot of effort to get it implemented.
This also starts work on splitting things out for theming.
