接下来我们学习document ready function。

首先，我们完成第一个 jQuery 语句。所有的 jQuery 函数以$开头，这个符号通常被称为美元符号（dollar sign operator）或bling。

jQuery 通常选取并操作带有选择器（selector）的 HTML 标签。

例如，如果要所有button有弹性的动画效果，只需在document ready function中添加如下代码即可：

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

请注意，为了能在编辑器里直接使用，我们已经为你在后台引入了 jQuery 库和 Animate.css 库。因此，你只需要通过 jQuery 给button元素添加bounce类就可以了。

--hints--

用 jQuery 的addClass()方法给button标签添加animated和bounce类。

assert($('button').hasClass('animated') && $('button').hasClass('bounce'));

仅用 jQuery 给标签添加颜色。

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

jQuery 代码应该放在$(document).ready();函数里。

assert(
  code.match(
    /\$\(document\)\.ready\(function.*(\s|\n)*.*button.*.addClass.*\);/g
  )
);
