There is no element with class ".personal" and so this code
is unnecessary. This should have been removed in 87e824d43e
when we changed the code to handle tabs to us
data-stream-section attribute instead of class.
This function was introduced in
99d1c5a1f3 and always has the opposite
value from what its name suggests. It worked OK because the caller
also expected it to have an incorrect value.
It's cleaner in this context to just use the `stream_id` helper, so
just delete the bad code and use that.
Fix the docstring comment having been incorrectly pushed down while
we're addressing this.
The `advanceKeyCodes` option was introduced in #10092.
It included a buggy check for `$.inArray` that returned
a falsey value only when the keycode was the first
element of `advanceKeyCodes`.
Because the only instance of `advanceKeyCodes` right now
is for search and contains only one element, this change
is functionally equivalent.
I confirmed that updater() only returns a string or undefined.
composebox_typeahead.js
- compsebox calls `content_typeahead_selected` which returns the composebox
text content
- stream and PM: implicitly returns undefined
pill_typeahead.js
- implicitly returns undefined
search.js
- narrow_or_search_for_term — returns `get_search_bar_text` or empty string
custom_profile_fields.js, settings_playground.js
- no updater function
If no updater function is provided, then updater returns the
value passed to it, which is
`this.$menu.find(".active").data("typeahead-value")`, which is a string.
All existing typeaheads have values for highlighter that are one
of the following:
* render_search_list_item (a handlebars render function)
* render_typeahead_item which calls a handlebars render function
* another function in typeahead_helper which eventually calls
typeahead_helper
All current definitions of header(), which is renamed to
header_text() in this commit:
composebox_typeahead.js
- `get_header_html` uses `_.escape`
- `render_topic_typeahead_hint` — is a handlebars function
- third typeahead doesn’t have a header function
custom_profile_fields.js, pill_typeahead.js, search.js,
and settings_playground.js have typeaheads, but none of them
have header functions.
This particular codepath is never reached right now,
because set_value is only called when `naturalSearch`
is `true`, and the only instance of `naturalSearch`
isn't for a `contenteditable` field.
But we don't need to use `html()` here because it's
displaying a plain string typeahead option.
Before ES2016, `indexOf` and jQuery's `inArray`
were used more often. They return -1 for a missing
element, and 0 is the only integer that’s falsy, so
-1 is the only integer whose bitwise complement is
falsy. Using bitwise not (~) like this is no longer
common practice and is a lot more confusing to read.
Now that we have `includes` we can use that instead.
