引导程序模式中的数据选择器无功能

Question

我使用日期选择器在模式框中显示日期，但文本字段不显示日期选择器功能。我尝试了没有弹出窗口的文本字段，它可以工作。如果在模式框内，则数据选择器在文本字段中不起作用。如何在弹出模式中修复日期选择器？希望有人可以指导我解决这个问题。谢谢。

下面是我的编码

<div class="form-group">
<label for="cp1" class="control-label col-lg-4">Effective date:</label>
<div class="col-lg-5">
<input type="text" class="form-control datepicker" id="date_borrowed" name="date_borrowed" title="date_borrowed" data-date-format="yyyy-mm-dd" readonly>            
<input type="hidden" class="form-control blank" id="id" name="id"  value="<?php echo md5($rs_wtp['id'] . $md5) ?>">
</div>
</div>

如果在模式框之外，则可以像下面的图片一样工作：

我已经使用bootstrap 4.5.0和bootstrap-datepicker 1.9.0测试了您的代码，datepicker在模式中运行良好。

$(document).ready(function() {
  $('.datepicker').datepicker();
});
