| # --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:
 | ||
| 
 | ||
| ```js
 | ||
| $("#target2").clone().appendTo("#right-well");
 | ||
| ```
 | ||
| 
 | ||
| 是否注意到这两个 jQuery 函数连在一起了? 这被称为<dfn>链式调用(function chaining)</dfn>,是一种用 jQuery 实现效果的简便方法。
 | ||
| 
 | ||
| 克隆 `target5` 元素,并将其附加到 `left-well` 。
 | ||
| 
 | ||
| # --hints--
 | ||
| 
 | ||
| `target5` 元素应该在 `right-well` 里面。
 | ||
| 
 | ||
| ```js
 | ||
| assert($('#right-well').children('#target5').length > 0);
 | ||
| ```
 | ||
| 
 | ||
| 应该克隆 `target5` 元素,并放在 `left-well` 里面。
 | ||
| 
 | ||
| ```js
 | ||
| assert($('#left-well').children('#target5').length > 0);
 | ||
| ```
 | ||
| 
 | ||
| 应该仅用 jQuery 移动这些元素。
 | ||
| 
 | ||
| ```js
 | ||
| assert(!code.match(/class.*animated/g));
 | ||
| ```
