我正在尝试使用 jQuery-ui-sortable 来允许用户自定义排序手牌。我试图让它们排序的 HTML 具有绝对定位的 div 元素，具有左侧边距样式并且是重叠的。
我的问题是，当我使容器元素可排序时，我可以单击并拖动各个卡片，但是当我释放鼠标按钮时，卡片会弹回其原始位置。
由于用户的手由一个数组支持，因此我不需要排序即可将卡片实际放置在新位置，尽管这将是一个不错的选择，因此我不必重新绘制手。所需要的只是获取释放鼠标按钮时助手/占位符悬停的索引。我也尝试了多种方法来获得它，但我一直在控制台中获得初始索引 + 1。
这是我的代码的一个小提琴：http: //jsfiddle.net/rcMwq/4/
