Bootstrap 模态框(Modal)插件

模态框(Modal)是覆盖在父窗体上的子窗体。通常,目的是显示来自一个单独的源的内容,可以在不离开父窗体的情况下有一些互动。子窗体可提供信息、交互等。
如果您想要单独引用该插件的功能,那么您需要引用 modal.js。或者,正如 Bootstrap 插件概览 一章中所提到,您可以引用 bootstrap.js 或压缩版的 bootstrap.min.js。

用法

您可以切换模态框(Modal)插件的隐藏内容:
通过 data 属性:在控制器元素(比如按钮或者链接)上设置属性 data-toggle="modal",同时设置 data-target="#identifier" 或 href="#identifier" 来指定要切换的特定的模态框(带有 id="identifier")。
通过 JavaScript:使用这种技术,您可以通过简单的一行 JavaScript 来调用带有 id="identifier" 的模态框:
$('#identifier').modal(options)

实例一、简单弹框

一个静态的模态窗口实例,如下面的实例所示:
