Question

我有一个文件夹树结构... 1个块的代码如下：

<div level="1" class="tree-item " ispublic="false" hassubfold="true" isworkspace="0" foldid="3595517$$QC4ixP" dcid="1" proid="54445$$vnwCUD" id="fold_3595517$$QC4ixP">
    <div style="padding-left: 30px; float: none; width: auto;" class="tree-row   ui-droppable selected">
            <span class="openFolder"></span>
        <span class="tree-label">1001</span>
    </div>
    <div class="tree-children" style="display: block;">
        <div>
        <div level="2" class="tree-item " ispublic="false" hassubfold="false" isworkspace="0" foldid="3711515$$AhXpf3" dcid="1" proid="54445$$vnwCUD" id="fold_3711515$$AhXpf3">
        <div style="padding-left: 50px; float: none; width: auto;" class="tree-row  ui-droppable">
        <a style="visibility:hidden;width:20px;" rel="undefined" title="Expand" class="folder" href="javascript:void(0);"></a>
        <a rel="54445$$vnwCUD" class="docList ui-droppable" title="rrrr" href="javascript:void(0);">
        <span class="closeFolder "></span>
        <span class="tree-label">rrrr</span>
        </a>
    </div>
    <div class="tree-children"></div>
</div>

我需要从包含复选框的列表中拖动文件并放入.tree-row（文件夹树）。当它丢弃d文件时，我需要得到树项目的折叠，我通过下面的代码获得：

event.target.parentElement.attributes['id'].value

使用上面的内容，我得到包含.tree-item的div的多个foldid。我需要获取仅删除文件的文件夹的文件夹ID，该文件夹再次是子文件夹....

function bindDragDropDocEvent(){    
    $(".tree-row").droppable({
        accept: '#fileContent .rows',
         tolerance: "touch", 

        drop:function(event,ui){
            event.stopPropagation();
            console.log(event);
            alert("dropped");
            var foldid = event.target.parentElement.attributes['foldid'].value;
            if(foldid!=0){
               foldid = event.target.parentElement.attributes['foldid'].value;  
               alert(foldid);
            }
         },
});

$("#fileContent .rows").draggable({
        cursor:'move',
        stop:function(event,ui){
            event.stopPropagation();
            var rowdata = ui.helper.find(':checkbox').data('rowValues');
            alert(rowdata.fileName);
         },
    });
}

任何人都可以请求帮助以获取仅可投放文件夹ID而不是其父级。我用过贪心：真实但没有运气！

我认为当你放弃它时，你的拖动触摸多个div，这就是为什么你也得到父div的id。可能的解决方案：

删除tolerance: "touch",
在.tree-row

如何从具有相同类的多个droppable获取父元素id？
