# --description--

这些动画开始看起来很酷，但是有时可能会让用户分心。

请删除 `document ready function` 内的三个 jQuery 函数，但保留 `document ready function` 本身。

# --hints--

应该删除 `document ready function` 中的三个 jQuery 函数。

```js
assert(code.match(/\{\s*\}\);/g));
```

应该保持 `script` 标签不变。

```js
assert(code.match(/<script>/g));
```

应该保持 `$(document).ready(function() {` 在 `script` 标签的开头不变。

```js
assert(code.match(/\$\(document\)\.ready\(function\(\)\s?\{/g));
```

应该保持 `document.ready` function 用 `})` 闭合。

```js
assert(code.match(/.*\s*\}\);/g));
```

应该保持 `script` 标签闭合。

```js
assert(
  code.match(/<\/script>/g) &&
    code.match(/<script/g) &&
    code.match(/<\/script>/g).length === code.match(/<script/g).length
);
```

    $("button").addClass("animated bounce");
