极客教程如何在Twitter Bootstrap中使用模态关闭事件
Bootstrap Modals提供了一个轻量级的、多用途的JavaScript弹出窗口，可定制且反应灵敏。它们可以用来在网站中显示警报弹出窗口、视频和图片。Bootstrap Modals分为三个主要部分：标题、正文和页脚。
语法:
class | tabindex | role | aria-labelledby
方法：它显示了带有标题、正文和页脚的弹出式菜单，以及关闭和提交按钮。
<div class="modal fade"
id="exampleModal"
tabindex="-1"
role="dialog"
aria-labelledby="exampleModalLabel"
aria-hidden="true">
<div class="modal-dialog" role="document">
</div>
</div>
解释：下面是一个静态模态的例子（意味着它的位置和显示已经被覆盖），包括模态标题、模态主体（需要填充）和模态页脚（可选）。我们要求你在可能的情况下将模态头与解雇动作包括在一起，或者提供另一个明确的解雇动作。
