javascript - 如何在 Bootstrap 折叠中折叠多个克隆元素之一

Question

我想折叠从旧元素克隆的另一个元素。但它会折叠我克隆的所有元素。

这里是JS

$(document).on('click','#addEm,.collap', function (e) {

    if($(this).is('#addEm')){

        var employerForm = $(this).closest('#employer').find('#cloneEm');

        var cloneDiv = employerForm.clone();
        $('#employerList').append(cloneDiv);
    }
    if($(this).is('.collap')) {

        if($(this).hasClass('glyphicon-plus')) {

            $(this).removeClass('glyphicon-plus');
            $(this).addClass('glyphicon-minus');
            $(this).closest('#employer').find('.employerForm').collapse('hide');
        }else if($(this).hasClass('glyphicon-minus')){

            $(this).removeClass('glyphicon-minus');
            $(this).addClass('glyphicon-plus');
            $(this).closest('#employer').find('.employerForm').collapse('show');
        }
    }

});

HTML:

    <div class="tab-pane" id="employer">

    <div class="panel-body ">
        <div class="text-right"><a id="addEm" class="btn btn-danger btn-md"> Add </a></div>
    </div>

    <div id="employerList">
    </div>

    <div class="panel-heading" id="cloneEm" style="margin-bottom: 15px;">
        <div class="text-right"><a class="collap btn btn-danger btn-xs glyphicon glyphicon-plus"> </a></div>
        <div class="panel-body">
            <div class="collapse employerForm">

                asdfasdfasdf

            </div>
        </div>
    </div>


</div>

似乎您的选择器正在定位 #employer，这是包含您所有链接的列表。

定位 #cloneEm 似乎有效。

$(document).on('click', '#addEm,.collap', function(e) {

  if ($(this).is('#addEm')) {

    var employerForm = $(this).closest('#employer').find('#cloneEm');

    var cloneDiv = employerForm.clone();
    $('#employerList').append(cloneDiv);
  }
  if ($(this).is('.collap')) {

    if ($(this).hasClass('glyphicon-plus')) {
      $(this).removeClass('glyphicon-plus');
      $(this).addClass('glyphicon-minus');

      $(this).closest('#cloneEm').find('.employerForm').collapse('hide');
    } else if ($(this).hasClass('glyphicon-minus')) {
      $(this).removeClass('glyphicon-minus');
      $(this).addClass('glyphicon-plus');
      $(this).closest('#cloneEm').find('.employerForm').collapse('show');
    }
  }
});
