--description--

除了移动标签，也可以把元素从一个地方复制到另一地方。

jQuery 有一个 clone() 方法，可以复制标签。

例如，如果想把 target2 从 left-well 复制到 right-well，可以设置如下：

$("#target2").clone().appendTo("#right-well");

是否注意到这两个 jQuery 方法连在一起了？这被称为链式调用（function chaining），是一种用 jQuery 实现效果的简便方法。

克隆 target5 标签并附加到 left-well。

--hints--

target5 标签应该在 right-well 内。

assert($('#right-well').children('#target5').length > 0);

应该克隆 target5 标签并放在 left-well 内。

assert($('#left-well').children('#target5').length > 0);

应该仅用 jQuery 移动这些标签。

assert(!code.match(/class.*animated/g));
