官方插件
概览
单个还是全部引入
JavaScript 插件可以单个引入（使用 Bootstrap 提供的单个 *.js 文件），或者一次性全部引入（使用 bootstrap.js 或压缩版的 bootstrap.min.js）。
建议使用压缩版的 JavaScript 文件
bootstrap.js 和 bootstrap.min.js 都包含了所有插件，你在使用时，只需选择一个引入页面就可以了。
编程方式的 API
我们为所有 Bootstrap 插件提供了纯 JavaScript 方式的 API。所有公开的 API 都是支持单独或链式调用方式，并且返回其所操作的元素集合（注：和jQuery的调用形式一致）。
$('.btn.danger').button('toggle').addClass('fat')
所有方法都可以接受一个可选的 option 对象作为参数，或者一个代表特定方法的字符串，或者什么也不提供（在这种情况下，插件将会以默认值初始化）：
$('#myModal').modal() // 以默认值初始化
$('#myModal').modal({ keyboard: false }) // initialized with no keyboard
$('#myModal').modal('show') // 初始化后立即调用 show 方法
事件
Bootstrap 为大部分插件所具有的动作提供了自定义事件。一般来说，这些事件都有不定式和过去式两种动词的命名形式，例如，不定式形式的动词（例如 show）表示其在事件开始时被触发；而过去式动词（例如 shown ）表示在动作执行完毕之后被触发。
所有以不定式形式的动词命名的事件都提供了 preventDefault 功能。这就赋予你在动作开始执行前将其停止的能力。
$('#myModal').on('show.bs.modal', function (e) {
if (!data) return e.preventDefault() // 阻止模态框的展示
})
模态框 modal.js
模态框经过了优化，更加灵活，以弹出对话框的形式出现，具有最小和最实用的功能集。
不支持同时打开多个模态框
千万不要在一个模态框上重叠另一个模态框。要想同时支持多个模态框，需要自己写额外的代码来实现。
模态框的 HTML 代码放置的位置
务必将模态框的 HTML 代码放在文档的最高层级内（也就是说，尽量作为 body 标签的直接子元素），以避免其他组件影响模态框的展现和/或功能。

无论何种实现方式，滚动监听都需要被监听的组件是 position: relative; 即相对定位方式。大多数时候是监听 <body> 元素。
通过 data 属性调用
