标题中的日期无明显原因显示为间隔

Question

我正在调整 titleFormat 以获得 Friday, April 21, 2017 但我得到了奇怪的结果：

dddd 呈现 Friday
LL 呈现 April 21, 2017
但是将两者放在一起，dddd LL，呈现为 Friday, April 21, 2017 – April 21, 2017

我错过了什么？

$(function() {
  $("#c1").fullCalendar({
    height: 100,
    defaultView: "agendaDay",
    allDaySlot: false,
    titleFormat: "dddd"
  });
  $("#c2").fullCalendar({
    height: 100,
    defaultView: "agendaDay",
    allDaySlot: false,
    titleFormat: "LL"
  });
  $("#c3").fullCalendar({
    height: 100,
    defaultView: "agendaDay",
    allDaySlot: false,
    titleFormat: "dddd LL"
  });
});

Answer 1

这显然是库中的错误 (#3645)。

标题中的日期无明显原因显示为间隔

Date in title shows as interval for no obvious reason

fullcalendar

fullcalendar-3
