Bootstrap JS 弹出框
JS 弹出框
Popover 组件类似于工具提示；它是当用户单击某个元素时出现的弹出框。不同之处在于弹出窗口可以包含更多内容。
有关 Popover 的教程，请阅读我们的Bootstrap 弹出窗口教程。
通过 data-* 属性启用
这个data-toggle="popover"激活弹出窗口。
这个title属性指定弹出窗口的标题文本。
这个data-content属性指定应显示在弹出窗口主体内的文本。
示例
<a href="#" data-toggle="popover" title="Popover Header" data-content="Some content inside the popover">Toggle popover</a>

通过JavaScript
Popover 不是纯 CSS 插件，因此必须使用 jQuery 进行初始化：选择指定的元素并调用 popover()方法。
示例
// Select all elements with data-toggle="popover" in the document
$('[data-toggle="popover"]').popover();
// Select a specified element
$('#myPopover').popover();
