Functions

@spec month_options(select_options()) :: [tuple()]

Generates a list of options for a month list that can be used with Phoenix.HTML.Form.options_for_select/2 or to create a <datalist>.

Arguments

Options

See Localize.HTML.Month.select/3 for options.

Returns

  • A list of {month_name, month_number} tuples.

select(form, field, options \\ [])

@spec select(
  form :: Phoenix.HTML.Form.t(),
  field :: Phoenix.HTML.Form.field(),
  select_options()
) :: Phoenix.HTML.safe()

Generates an HTML select tag for a month name list that can be used with a Phoenix.HTML.Form.t.

Arguments

Options

  • :months defines the list of month numbers to be displayed. The default is 1..12.

  • :calendar is the calendar module from which the month names are derived. The default is Calendar.ISO, which renders Gregorian labels. If the calendar module exports cldr_calendar_type/0, the returned atom selects the CLDR calendar used for the labels (for example, Cldr.Calendar.Hebrew returns :hebrew). Calendars without that function fall back to Gregorian labels.

  • :year is the year from which the number of months is derived. The default is the current year.

  • :locale defines the locale used to localise the month names. The default is the locale returned by Localize.get_locale/0.

  • :style is the format of the month name. The options are :wide (the default), :abbreviated and :narrow.

  • :collator is a function used to sort the months. The default collator preserves month order.

  • :mapper is a function that creates the text to be displayed in the select tag for each month. It receives a tuple {month_name, month_number}. The default is the identity function.

  • :selected identifies the month to be selected by default in the select tag. The default is nil.

  • :prompt is a prompt displayed at the top of the select box.

Returns
