Question

我尝试了很多这个问题的解决方案：set default time in bootstrap-datetimepicker

但他们都没有奏效。它们都会导致输入为空，并默认为占位符文本。

我尝试了setDate()，setLocalDate()和defaultDate路由但我在当前文档中找不到任何支持这些或任何当前方法来完成此简单任务的内容。

这些都不起作用：

var dateObj = new Date('2016-03-21T23:31:00');
// does not work, causes empty input/placeholder text
$("#startdatetime-from").data('datetimepicker').setDate(dateObj);
// does not work, causes empty input/placeholder text
$("#startdatetime-from").data('datetimepicker').setLocalDate(dateObj);


var dateObj = new Date('2016-03-21T23:31:00');
$('#new-challenge-date-time-picker').datetimepicker({
    minDate: moment(),
    defaultDate: dateObj // does not work, same symptoms as above
});

我也尝试设置value本身的#new-challenge-date-time-picker属性，但这也不起作用。

有没有人有答案？

初始化选择器时，您可以将日期传递给“defaultDate”。但minDate将覆盖defaultDate。因此，如果您还需要minDate，请将useCurrent设置为false

尝试以下

   $(function() {

  var datePreset = $('#new-challenge-date-time-picker').attr('data-preset');
  var dateParts = datePreset.split(' ');
  var dateString = dateParts[0];
  var dateTime = dateParts[1];
  var dateTimeParts = dateTime.split(':');
  var dateHour = dateTimeParts[0];
  var dateMinutes = dateTimeParts[1];
  var dateAMPM = dateParts[2];
  var dateStringParts = dateString.split('/');
  var dateMonth = dateStringParts[0];
  var dateDay = dateStringParts[1];
  var dateYear = dateStringParts[2];

  var time = (dateAMPM == 'PM') ? (parseInt(dateHour) + 12) + ':' + dateMinutes : dateHour + ':' + dateMinutes;
  time += ':00';

  console.log(dateYear + '-' + dateMonth + '-' + dateDay + 'T' + time);
  var dateObj = new Date(dateYear + '-' + dateMonth + '-' + dateDay + 'T' + time);

  $('#new-challenge-date-time-picker').datetimepicker({
    minDate: moment(),
    defaultDate: dateObj,
     useCurrent:false
  });

  // $("#new-challenge-date-time-picker").data('datetimepicker').setDate(dateObj);


});

您可以使用defaultDate选项初始化日期。如果要使用data-*属性来初始化组件，可以使用以下代码：

var datePreset = $('#new-challenge-date-time-picker input').attr('data-preset');
var dateFormat = $('#new-challenge-date-time-picker input').attr('data-format');

$('#new-challenge-date-time-picker').datetimepicker({
    minDate: moment(),
    defaultDate: moment(datePreset, dateFormat)
});

              <input type='text' class="form-control" data-format="MM/DD/YYYY HH:mm:ss A" data-preset="03/21/2016 11:31:00 PM"/>
                <span class="input-group-addon">
                    <span class="glyphicon-calendar glyphicon"></span>
                </span>
            </div>
        </div>
    </div>
</div>

请注意，格式必须遵循parsing rules时刻。我删除占位符是因为这个开放的错误：Default date not working。
