$('#StartDate').datetimepicker(
                {
                    format: 'DD MMM YYYY hh:mm A'

                });

其中startDate是divId

<div class="input-group date form_datetime" id="StartDate">
         <input type="text" class="form-control input-lg" placeholder="From" name="StartDate" id="txtStartDate" required /> 
<span class="input-group-addon">
<span class="glyphicon-calendar glyphicon"></span></span>
 </div>

这将为您提供如下格式：2016年3月25日01：08 PM

试试看

$('#occasionStartTime').datetimepicker({
    datepicker : false,
    ampm: true, // FOR AM/PM FORMAT
    format : 'g:i A'
});

$('#occasionStartTime').datetimepicker({
        format: 'Y/m/d A g:i',
        formatTime: 'A g:i',
    });

使用Bootstrap Datepicker 3的MVC默认日期格式-对初学者非常有用

@Scripts.Render("~/bundles/jquery")
@Scripts.Render("~/bundles/bootstrap")
<script src="~/Content/datepicker/moment.js"></script>
<link href="~/Content/datepicker/bootstrap-datetimepicker.css" rel="stylesheet" />
<script src="~/Content/datepicker/bootstrap-datetimepicker.js"></script>

$(function () {
        $('.datetime').datetimepicker({
            format: 'DD-M-YYYY hh:mm A'
        });

    });

</script>

使用这个插件可以不引人注意地添加一个日期时间选择器，日期选择器或时间选择器下拉列表到您的表单。很容易自定义选项。
您可以下载Plugin：Download
添加js和css到head标签：

<link rel="stylesheet" type="text/css" href="./js/jquery.datetimepicker.css" />
<script src="./js/jquery.datetimepicker.js"></script>

将此代码添加到您想要显示的内容：

$(function () {
    $('#video_schedule').datetimepicker({
        step:5,
        minDate:0,
        formatTime:'H:i'
    });
});

如果您只有时间字段而不是日期时间字段-您可以使用

$("#yourTimeField").timepicker({
        showPeriod: true
 });

将datatimetepicker格式值设置为format: 'hh:mm A'

工作示例。

$(function() {
  $('#datetimepicker1').datetimepicker({
      format: 'hh:mm A',
  });
  $('#datetimepicker2').datetimepicker({
      format: 'DD/MM/YYYY hh:mm A',
  });
});

在现在的版本中，2021 / 1 / Jan您必须输入例如：

$('#dateTimePicker').datetimepicker({
            .....,
            formatTime:'g:iA',
            format: 'Y.m.d hh:mm A',
            .....
        }

你就完了

没有任何工作对我来说，因为我首先使用的是常见的'bootstrap-datetimepicker'，它与bootstrap一起提供：

JS代码

$('.date-picker-2').datetimepicker({
    format: 'Y-m-d h:i a',
    todayHighlight: 'TRUE',
    autoClose: true,
    orientation: 'bottom right',
    step: 5
