itself.
We were checking for the undefined value of `$html_item` but this
variable is always true since `$.find` never returns an undefined value
and it returns a JQuery collection instead.
So we need to check the length of that JQuery collection here to make
sure that the condition works as expected.
After migrating to TypeScript, we don't need to manually validate the
configuration passed to the `ListWidget`, that's what typescript complier
will do for us, hence I removed `validate_opts` and `valid_filter_opts`
functions.
This is a prep commit for typescript migration of this module. In this commit
I made all the users of ListWidget pass generic sort functions like 'alphabetic'
and 'numeric' explicitly to avoid type conversions which we may need when moving
to typescript, also it simplifies our `set_sorting_function` a bit more.
This is a prep commit for moving towards typescript migration of this module.
We should make `get_item` required on `list_widget` because its intended to be
used with a set of keys and then hydrate the keys lazily. Also this will help
us to avoid writing messy if-conditions while filtering and sorting and make
our life much easier when we migrate to TypeScript.
I added a `default_get_item` function which is just n identity function and
also refactored some code to make use of default get item.
This lets us simplify the long-ish ‘../../static/js’ paths, and will
remove the need for the ‘zrequire’ wrapper.
