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.
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.
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.
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.
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 closes https://github.com/select2/select2/issues/2974.
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.
This closes https://github.com/select2/select2/issues/3005.
This closes https://github.com/select2/select2/issues/818.
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.
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.
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.
I18n translations expect a "maximum" argument for inputTooLong message,
but MaximumInputLength is passing "minimum". This renames "minimum" to
"maximum" to fix this problem.
This adds back the `ajax.transport` option, which allows anyone to
use their own AJAX backend. By default, `jQuery.ajax` is used as the
default transport backend.
**Breaking change:** Instead of taking `params` that contains a
`success` and `error` keys for the callback, two new callback
parameters are passed alongside of `params` that should be called
when the request succeeds or fails.
This closes https://github.com/select2/select2/issues/2987.
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 prevents scrolling within scrollable containers (excluding the
dropdown) when the dropdown is open. This fixes an issue where the
dropdown would go out of sync with the parent container when the
parent container was scrolled.
We did not have this issue in past versions of Select2 because the
mask prevented any scrolling. Now that we have removed the mask, we
have to deal with scrolling from different areas of the page.
We initially tried to hook into the `scroll` events of the parent
containers, but because of a list of issues we decided against it.
If the container scrolled out of view, the dropdown would still be
left open and above everything else, even though the container
wasn't visually connected to it.
The `scroll` event does not bubble, so we need to attach the `scroll`
handler to every parent element that is scrollable. Since it is
surprisingly difficult to determine if an element is scrollable,
we modified some CC-BY-SA code and use that to determine if the
element has a scrollbar. The original `hasScroll` function can be
found at http://codereview.stackexchange.com/q/13338, the same link
left within the code, and was originally designed to be a sizzle
selector. As Select2 does not require a sizzle-compatible version of
jQuery, we converted it into a function that could be used with
`.filter` to filter down the elements.
This closes https://github.com/select2/select2/issues/2975.
