# --description--
|
|
|
|
In addition to moving elements, you can also copy them from one place to another.
|
|
|
|
jQuery has a function called `clone()` that makes a copy of an element.
|
|
|
|
For example, if we wanted to copy `target2` from our `left-well` to our `right-well`, we would use:
|
|
|
|
`$("#target2").clone().appendTo("#right-well");`
|
|
|
|
Did you notice this involves sticking two jQuery functions together? This is called <dfn>function chaining</dfn> and it's a convenient way to get things done with jQuery.
|
|
|
|
Clone your `target5` element and append it to your `left-well`.
|
|
|
|
# --hints--
|
|
|
|
Your `target5` element should be inside your `right-well`.
|
|
|
|
```js
|
|
assert($('#right-well').children('#target5').length > 0);
|
|
```
|
|
|
|
A copy of your `target5` element should also be inside your `left-well`.
|
|
|
|
```js
|
|
assert($('#left-well').children('#target5').length > 0);
|
|
```
|
|
|
|
You should only use jQuery to move these elements.
|
|
|
|
```js
|
|
assert(!code.match(/class.*animated/g));
|
|
```
