flatpickr 在选择后格式化最终值

Question

我有以下 html：

<div class="form-group">
    @Html.LabelFor(x => x.StartDate)
    @Html.TextBoxFor(m => m.StartDate, "{0:dd-MM-yyyy}", new { type = "text", @class = "flatpickrStart form-control", @id = "absenceStartDate", @Required = true })
    @Html.ValidationMessageFor(x => x.StartDate, null, new { @class = "text-danger" })
</div>
<div class="form-group">
    @Html.LabelFor(x => x.EndDate)
    @Html.TextBoxFor(m => m.EndDate, "{0:dd-MM-yyyy}", new { type = "text", @class = "flatpickrEnd form-control", @id = "absenceEndDate", @Required = true })
    @Html.ValidationMessageFor(x => x.EndDate, null, new { @class = "text-danger" })
</div>

和脚本：

function InitializeDateTimePickers() {
    $(".flatpickrStart, .flatpickrEnd").flatpickr({
        dateFormat: "dd-MM-yyyy H:i:s",
        enableTime: true,
        weekNumbers: true,
        altInput: true,
        altFormat: "F j, Y - h:i",
        time_24hr: true
    });
}

以我的codepen为例： https://codepen.io/andrelange91/pen/YOgwaJ

选择工作正常，但是当我选择了一个值时， 我得到的价值在某些地方似乎是双倍的。

例如，我使用选择器选择此：2018 年 9 月 21 日 - 8:00 返回的值是这样的：2121-SepSep-18181818 08:00:0

我有办法获得正确的日期时间格式吗？ 第一次使用这个插件，目前还没找到解决办法。

无需编写两次代码。只写一次

$(".flatpickrStart, .flatpickrEnd").flatpickr({ 
   dateFormat: "d-M-y H:i:s", //change format also 
   enableTime: true, 
   weekNumbers: true, 
   altInput: true, 
   altFormat: "F j, Y - h:i", 
   time_24hr: true 
});

你的问题将会得到解决。

工作片段：-

$(".flatpickrStart, .flatpickrEnd").flatpickr({
  dateFormat: "d-M-y H:i:s",
  enableTime: true,
  weekNumbers: true,
  altInput: true,
  altFormat: "F j, Y - h:i",
  time_24hr: true
});



$(".flatpickrEnd").on("change", function() {
  $("#endValue").text($(this).val());
});
$(".flatpickrStart").on("change", function() {
  $("#startValue").text($(this).val());
});
