角的DragDrop - 如何重新排列物品 [英] Angular DragDrop - how to reorder items

问题描述

局势：

我有一个应用程序，利用角的DragDrop 移动之间的项目三个独立的名单。

I have an app that make use of angular-dragdrop to move items between three separate list.

拖放工作正常。但我也需要重新排序同一列表内的项目。

The drag and drop is working fine. But i also need to reorder the items inside the same list.

我看这是可能也retrive指数上onDrop的文件中，但我不知道怎么办。
如果我将能够以检索索引 - 这正是该项目是新的数组中留下的位置 - 那么我将能够使重新排序

I see in the documentation that is possible to retrive the index also on the onDrop, but i don't know how. If i will be able to retrive the index - that is the position where the item is left in the new array - then i would be able to make the reordering

总code：

        <ul class="thumbnails">
          <li class="span3" style='margin-left:10px;'>
            <div class="thumbnail" data-drop="true" ng-model='list1' data-jqyoui-options="optionsList1" jqyoui-droppable="{multiple:true}">
              <div class="caption">
                <div class="btn btn-info btn-draggable" ng-repeat="item in list1" ng-show="item.title" data-drag="{{item.drag}}" data-jqyoui-options="{revert: 'invalid'}" ng-model="list1" jqyoui-draggable="{index: {{$index}}, animate:true, onStart:'set_item_id({board_item_id: item.item_id}, {index: $index})'}">{{item.title}}</div>
              </div>
            </div>
          </li>
          <li class="span3" style='margin-left:10px;'>
            <div class="thumbnail" data-drop="true" ng-model='list2' data-jqyoui-options="{accept:'.btn-draggable:not([ng-model=list2])'}"  jqyoui-droppable="{multiple:true}">
              <div class="caption">
                <div class="btn btn-info btn-draggable" ng-repeat="item in list2" ng-show="item.title" data-drag="{{item.drag}}" data-jqyoui-options="{revert: 'invalid'}" ng-model="list2" jqyoui-draggable="{index: {{$index}},animate:true, onStart:'set_item_id({board_item_id: item.item_id}, {index: $index})'}">{{item.title}}</div>
              </div>
            </div>
          </li>
          <li class="span3" style='margin-left:10px;'>
            <div class="thumbnail" data-drop="true" ng-model='list3' data-jqyoui-options="{accept:'.btn-draggable:not([ng-model=list3])'}"  jqyoui-droppable="{multiple:true}">
              <div class="caption">
                <div class="btn btn-info btn-draggable" ng-repeat="item in list3" ng-show="item.title" data-drag="{{item.drag}}" data-jqyoui-options="{revert: 'invalid'}" ng-model="list3" jqyoui-draggable="{index: {{$index}},animate:true, onStart:'set_item_id({board_item_id: item.item_id}, {index: $index})'}">{{item.title}}</div>
              </div>
            </div>
          </li>

        </ul>

非常感谢你！

推荐答案

您需要，以确保排序选项在列表中已启用添加额外的指令。

You need to add additional directives in order to make sure the sorting option is enabled in the list.

data-drop="true" jqyoui-droppable="{index: {{$index}}}"
