                            <div class="modal-dialog">
                                <div class="modal-content">
                                    <div class="modal-header">

                                        <button type="button" class="btn btn-secondary modal-submit"><i class="glyphicon glyphicon-ok"></i></button>
                                        <button type="button" class="btn btn-primary modal-close" class="close" data-dismiss="modal"><i class="glyphicon glyphicon-remove"></i></button>

                        </div>

使用 DatetimePicker 的代码

<a href="#" data-pk="175" data-title="Booking Date" data-name="booking_date" class="datetime-picker">
                                                    2020-09-12 00:00:00</a>
<a href="#" data-pk="175" data-title="Booking Date" data-name="booking_date" class="datetime-picker">
                                                    2020-09-29 00:00:00</a>



$("body").on('click', '.datetime-picker', function() {
            let d = $.trim($(this).text());
            // d = moment(new Date(d));
            var today = new Date(d);
            var date = today.getFullYear() + '-' + (today.getMonth() + 1) + '-' + today.getDate();
            var time = today.getHours() + ":" + today.getMinutes();
            var dateTime = date + ' ' + time;
            console.log('dateTime', dateTime);
            $("#myModal2").modal({
                backdrop: 'static',
                keyboard: false
            })


            $('#datetimepicker12').datetimepicker({
                inline: true,
                sideBySide: true,
                format: 'yyyy-mm-dd hh:ii',
                defaultDate: dateTime,
            });

            $("#myModal2").modal('show');


            // $('#datetimepicker12').data("DateTimePicker").date(moment(previousDate).format('DD/MM/YYYY HH:mm'));
        })

Answer 1

您需要独立于主体事件处理程序实例化 datetimepicker。

为了设置你需要使用momentjs lib的defaultDate：

$('#datetimepicker12').datetimepicker('defaultDate', moment(d));

$('#datetimepicker12').datetimepicker({
    inline: true,
    sideBySide: true,
    format: 'yyyy-mm-dd hh:ii'
});
$("body").on('click', '.datetime-picker', function() {
    let d = $.trim($(this).text());
    $('#datetimepicker12').datetimepicker('defaultDate', moment(d));

    $("#myModal2").modal({
        backdrop: 'static',
        keyboard: false
    });
    $("#myModal2").modal('show');
})
