如何折疊引導程序折疊中的多個克隆元素之一

Question

我想折疊我從舊元素中克隆的另一元素。 但這會使我克隆的所有元素崩潰。

這是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>

似乎您的選擇器定位到#employer ，這是環繞所有鏈接的列表。

定位#cloneEm似乎可行。

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