Question

我有两个文本框，它们采用日期时间值，并且日期时间是从Bootstrap DateTimePicker设置的。现在我想使用JavaScript减去两个日期时间值并将其保存在数据库中？

这是我的日期时间选择器代码：

<script type="text/javascript">
        $(function () {
            $("#<%=datetimeCreated.ClientID %>").datetimepicker({
                calendarWeeks: true,
                useCurrent: false,
                format: 'YYYY-MM-DD HH:mm:ss',

            });

            $("#datetimeCreated").on('dp.change', function (e) {
                var date = $("#datetimeCreated").val();

            });

        });


        $(function () {
            $("#<%=datetimeClosed.ClientID%>").datetimepicker({
                calendarWeeks: true,
                format: 'YYYY-MM-DD HH:mm:ss',
            });

            $("#datetimeClosed").on('dp.change', function (e) {
                var date = $("#datetimeClosed").val();
            });
        });

您可以使用moment.js（这是datetimepicker已经需要）来计算差异，如下所示：

var diff = moment.duration(date1.diff(date2)).asDays();

详细了解文档中的https://jsfiddle.net/u49xmns3/和.duration()。

阅读代码，如果不清楚，请告诉我。

$(function () {
  $('#datetimepicker1, #datetimepicker2').datetimepicker();
  
  $('button').click(function(e) {
    e.preventDefault();
    var date1 = $('#datetimepicker1').data('DateTimePicker').date();
    var date2 = $('#datetimepicker2').data('DateTimePicker').date();
    var diff = moment.duration(date1.diff(date2)).asDays();
    // here is what are you looking for:
    console.log(diff);
  });
});
