【问题描述】：

我目前正在使用引导日期选择器，但遇到了问题。我想以格式（dd/mm/yyyy）从日期选择器中读取值。但是，即使用户选择了日期值，我仍然会收到一个空字符串。这是我的代码

$('#startDateInput').datepicker(
        format: 'dd/mm/yyyy',
    );

    $('#saveButton').on('click', function () 
        var collectedStartDate = $('#startDateInput').datepicker().val();
        alert(collectedStartDate);
    );

<link href="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.8.0/css/bootstrap-datepicker.css" rel="stylesheet"/>

<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<script src="https://stackpath.bootstrapcdn.com/bootstrap/4.1.1/js/bootstrap.min.js"></script>
<script src="https://cdnjs.cloudflare.com/ajax/libs/bootstrap-datepicker/1.8.0/js/bootstrap-datepicker.js"></script>
<div class="form-group col-md-12">
    <label class="control-label col-md-4" for="startDateInput">Start date</label>
    <div class="input-group date" id="startDateInput" style="max-width: 280px" data-provide="datepicker">
        <input type="text" class="form-control">
        <div class="input-group-addon">
            <span class="glyphicon glyphicon-calendar"></span>
        </div>
    </div>
</div>

<div class="form-group col-md-12">
    <label class="control-label col-md-1"></label>
    <div class="col-md-10">
        <div class="pull-right">
            <input type="button" class="btn btn-primary" value="Save" id="saveButton" />
        </div>
    </div>
</div>

试试

  format: 'dd/mm/yyyy',
);

$('#saveButton').on('click', function() 
  var collectedStartDate = $('#startDateInput').data('datepicker').getFormattedDate('dd/mm/yyyy');
  alert(collectedStartDate);
);

<div class="form-group col-md-12">

      <input type="button" class="btn btn-primary" value="Save" id="saveButton" />
    </div>
  </div>
</div>

【参考方案2】：

编辑

.datepicker('getDate'); 返回 javascript date object

var dateInput = $('#startDateInput').datepicker(
  format: 'dd/mm/yyyy',
);

$('#saveButton').on('click', function() 
  var collectedStartDate = dateInput.datepicker('getDate');
  alert(collectedStartDate.getDate() + '/' + (collectedStartDate.getMonth() + 1) + '/' +  collectedStartDate.getFullYear());
);

  <div class="col-md-10">
    <div class="pull-right">
      <input type="button" class="btn btn-primary" value="Save" id="saveButton" />
    </div>
  </div>

您好，如何仅在 dd/mm/yyyy 中获取日期？因为您的解决方案给了我一个更具体的日期，这不是我想要的 Thu Jun 14 2018 00:00:00 GMT+0800（新加坡标准时间）
