# --description--
|
|||
|
|
|
|||
|
|
現在來把標籤從一個 `div` 移動到另一個裏。
|
|||
|
|
|
|||
|
|
jQuery 有一個 `appendTo()` 方法，可以選取 HTML 標籤並將其添加到另一個標籤裏面。
|
|||
|
|
|
|||
|
|
例如，如果要把 `target4` 從 right well 移到 left well，可以設置如下：
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
$("#target4").appendTo("#left-well");
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
把 `target2` 元素從 `left-well` 移動到 `right-well`。
|
|||
|
|
|
|||
|
|
# --hints--
|
|||
|
|
|
|||
|
|
`target2` 元素不應該在 `left-well` 內。
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
assert($('#left-well').children('#target2').length === 0);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
`target2` 元素應該在 `right-well` 內。
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
assert($('#right-well').children('#target2').length > 0);
|
|||
|
|
```
|
|||
|
|
|
|||
|
|
應該僅用 jQuery 移動這些標籤。
|
|||
|
|
|
|||
|
|
```js
|
|||
|
|
assert(!code.match(/class.*animated/g));
|
|||
|
|
```
|
|||
|
|
|
|||
