可排序的克隆助手无法正常工作 [英] Sortable clone helper not working
问题描述
也许我不明白克隆如何与可排序一起工作，但这就是我想要做的。
Maybe I don't understand how clone works with sortable, but here is what I would like to do.
在对项目进行排序时，我希望保留一个项目的克隆，直到我停止将项目放在新位置。
When sorting an item I would like a clone of the item I am dragging remain until I stop drop the item in its new position.
以下是代码：
<html>
<head>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script>
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.2/jquery-ui.min.js"></script>
<style type="text/css">
.sort { width: 150px; }
.ui-state-highlight { background-color: #000; height:2px; }
</style>
</head>
<body>
<div>
<ul class="sort">
<li>Item 1</li>
<li>Item 2</li>
<li>Item 3</li>
<li>Item 4</li>
</ul>
</div>
<script type="text/javascript">
$(function() {
$('.sort').sortable({
helper: 'clone',
placeholder: 'ui-state-highlight',
opacity: '.5'
})
})
</script>
</body>
</html>
提前感谢您的帮助！
推荐答案
当您使用克隆选项时，开始拖动时，原始项目将隐藏 style =display：none。您可以将处理程序附加到sort事件（或隐藏原始项目的任何事件）以重新显示它。那么一切都适合你。
When you use the clone option, the original item is hidden with style="display: none" when you start dragging. You could attach a handler to the sort event (or whatever event hides the original item) to re-show it. Everything should work for you then.
P.S。我使用 Firebug 来查看原始元素发生了什么。如果你没有使用它，你真的应该是！
P.S. I used Firebug to look at what was happening to the original element. If you're not using it you really ought to be!
