javascript - 日期范围没有克隆

Question

为了获取在输入中选择的日期，我使用data range picker 我遇到的问题是，当克隆输入时，日期函数不再起作用，我似乎无法弄清楚我做错了什么。 看来我只能执行一次数据选择器功能。

$(function() {

  $('input[name="opl_datum"]').daterangepicker({
      autoUpdateInput: false,
      showDropdowns: true,
      autoApply: true,
      locale: {
          format:'DD/MM/YYYY',
          daysOfWeek: [
          	'Zo',
          	'Ma',
          	'Di',
          	'Wo',
          	'Do',
          	'Vr',
          	'Za',
          ]
      }
  });

  $('input[name="opl_datum"]').on('apply.daterangepicker', function(ev, picker) {
      $(this).val(picker.startDate.format('DD/MM/YYYY') + ' - ' + picker.endDate.format('DD/MM/YYYY'));
   });
   
     $(document).on('click', '.btn-add', function(e) {
    e.preventDefault();

    var controlForm = $(this).closest('.controls').find('form:first'),//you have to select colsest controls
      currentEntry = $(this).parents('.entry:first'),
      newEntry = $(currentEntry.clone()).appendTo(controlForm);

    newEntry.find('input').val('');
    controlForm.find('.entry:not(:last) .btn-add')
      .removeClass('btn-add').addClass('btn-remove')
      .removeClass('btn-success').addClass('btn-danger')
      .html('<span class="icon_minus_alt2"></span>');
  }).on('click', '.btn-remove', function(e) {
    $(this).parents('.entry:first').remove();

    e.preventDefault();
    return false;
  });
  

});

默认情况下，jQuery 的 clone方法不会克隆事件处理程序和与 DOM 节点关联的数据，而只会克隆节点本身。您必须将特定参数 ( withDataAndEvents and deepWithDataEvents ) 传递给 clone 才能复制这些参数。
