如何将一个draggable拖放到一个sortable中，拖放的item不是原始元素而是一个自定义的helper

Question

jQuery draggeble/sortable demo only shows how to drop a clone of the draggable (draggable and sortable items have the same structure). I want to drop a different DOM structure. For instance, when I drag a simply div, the dragged element gets converted into a complexer DOM structure. See the jsfidler 示例，请注意助手的变化，我想删除助手，但原始项目被删除了。

使用简单的可拖动项目和可放置容器是可行的，但我希望能够将项目放在可排序容器的任何部分并能够重新排序元素。

知道如何实现我正在寻找的东西吗？

 $(function() {
    $(".portlet-container").sortable({
        handle: ".portlet-header",
        cursor: "move",
        placeholder: "ui-state-highlight"
    }).droppable({
        accept: ".portlet-clone",
        drop: function(event, ui) {
          return $(ui.helper).clone(true, true)
            .removeClass('ui-draggable-dragging')
            .removeClass('portlet-clone')
            .css("position", "")
            .css("left", "")
            .css("top", "").appendTo(this);
        }
    });

    $('.portlet-name').draggable({
        connectToSortable: ".portlet-container",
        cursor: 'move',
        revert: 'invalid',
        opacity: 0.7,
        helper: portletHelper
    });


    function portletHelper(event) {
        var portletWrapperStr = "<div class='portlet-wrapper portlet-clone' style='height:" + $(this).data("div-height") + "px; width:" + $(this).data("div-width") + "px;'/>";
        var portletStr = "<div class='portlet' " +
                          "style='height:" + ($(this).data("div-height") - 40 - 2) + "px;'>" +
                          "<div class='portlet-header'>" + $(this).html() + "</div>" +
                          "</div>";

        var portlet = $(portletStr);
        var portletWrapper = $(portletWrapperStr).append(portlet);
        return portletWrapper;
    }
});

好的，以下解决了您的问题：

当我们将元素拖放到 sortable 上时，我们必须更新拖放的元素 html 并将其设置为您想要的。

当您已经将可拖动项链接到可排序列表时，您不必添加可放置项。

$( function() {
    $( ".portlet-container" ).sortable({
        cursor : "move",
        placeholder: "ui-state-highlight",
        handle: ".portlet-header",
        update: function(event, ui){
            if($(ui.item).hasClass('portlet-wrapper')){
            // we don't add one if we're sorting a pre-existing item    
          } else {
            ui.item.html(portletClone(ui.item))
            ui.item.removeClass('portlet-item portlet-name ui-draggable')
                    .addClass('portlet-wrapper');
          }
        }
    });

    $('.portlet-name').draggable( { 
          connectToSortable: ".portlet-container",
        cursor: 'move',
        revert: 'invalid',
        opacity: 0.7,
        helper: portletHelper
    });

    function portletHelper( event ) {
        return portletClone(this);
    }

    function portletClone(item){
        var portletWrapperStr = "<div class='portlet-wrapper portlet-clone' style='height:"+$(item).data("div-height")+"px; width:"+$(item).data    "div-width")+"px;'/>";            
        var portletStr ="<div class='portlet' "+
                        " style='height:"+($(item).data("div-height")-40-2) +"px;'>"+  
                        " <div class='portlet-header'>"+$(item).html()+"</div>"+
                        "</div>";  

        var portlet = $(portletStr);
        var portletWrapper = $(portletWrapperStr).append(portlet);
        return portletWrapper;
  }
});
