JQuery：将行为转移到克隆对象
我试图通过将 clone() 方法绑定到 doubleclick 事件来快速制作类的副本。到目前为止，我的代码是：
<style type="text/css">
.draggable { float:left; clear: both; }
</style>
<script type="text/javascript">
$(function() {
copyit = function() {
$(this).clone().appendTo("body").css('position','absolute').draggable();
}
$('.draggable').dblclick(copyit);
$('.draggable').draggable();
});
</script>
<div class="draggable">Hi There!</div>
<div class="draggable">What's up?</div>
一切正常，除了克隆元素添加到 DOM 后我无法让它们克隆自身。非常感谢任何帮助。
I'm trying to quickly make copies of a class by binding the clone() method to the doubleclick event. My code, so far is:
<style type="text/css">
.draggable { float:left; clear: both; }
</style>
<script type="text/javascript">
$(function() {
copyit = function() {
$(this).clone().appendTo("body").css('position','absolute').draggable();
}
$('.draggable').dblclick(copyit);
$('.draggable').draggable();
});
</script>
<div class="draggable">Hi There!</div>
<div class="draggable">What's up?</div>
Everything works, except I can't get the cloned elements to clone themselves once they are added to the DOM. Any help is greatly appreciated.

我的猜测是您没有将 dblclick 事件绑定到新的 DOM 节点。在这种情况下，您实际上有两种方法可以实现此目的：
您可以使 dblclick 成为实时（或委托）事件，如下所示：
$('.draggable').live('dblclick', copyit);
看：

http://api.jquery.com/delegate/
您可以使克隆复制对象的事件通过传递 true 来实现，如下所示：
$(this).clone(true).appendTo("body").css('position','absolute').draggable();
看：
http://api.jquery.com/clone/
My guess is that you are not binding the dblclick event to the new DOM nodes. In this case you actually have 2 ways you can accomplish this:
You can make the dblclick a live (or delegate) event like this:
$('.draggable').live('dblclick', copyit);
see:
http://api.jquery.com/live/
http://api.jquery.com/delegate/
You can make the clone copy the events of the object by passing it true, like this:
$(this).clone(true).appendTo("body").css('position','absolute').draggable();
see:
http://api.jquery.com/clone/
使用
.live()设置双击处理程序：Set up the double-click handler with
.live():
