Since Select2 methods should not be called on an element where
Select2 has not yet been initialized, this raises an error when it
happens. This does not silence the original error, but it does
provide the user with some more context about why they are seeing
a TypeError.
This closes https://github.com/select2/select2/issues/3173.
This exposes the default options for Select2 as
`$.fn.select2.defaults`. A default option can be set using the
`set(key, val)` option which is available. The key should use the
same formatting as the HTML data attributes.
This also adds some documentation about it.
This should allow those using their own build systems to
automatically load in translations. In the future, the `amdBase`
option may be used to optionally load some components of Select2.
As Select2 cannot know what the base directory is, it currently
has to load in all of the optional components in the default build.
By allowing users to set their own base, it will allow us to know
the base to load files from, which makes it easier to use the
`require` function to optionally load them.
This fixes https://github.com/select2/select2/issues/2899.
jQuery.mousewheel will allow us to prevent the dropdown from
automatically closing when the user scrolls to the end of the list.
It is automatically bundled in the full versions of Select2 and
we don't require that it is included in order for Select2 to work.
jQuery.mousewheel was taken directly from the source repository
using the commit at
cc2c5d73ae
This will always clone the options that are passed in when
initializing Select2 on multiple objects (like `$("select")`) so
it doesn't always assume that the configuration is the exact same.
This prevents any reference-based tricks for modifying the data
within Select2, but some would look at that as an upside.
