Bootstrap pop-up box (Popover) plug-in
The pop-up box (Popover) is similar to the tool tip (Tooltip), providing an expanded view. To activate the popover, users simply hover over the element. The content of the popup box can be filled entirely using the Bootstrap Data API. This method relies on tooltips.
Usage
The popover plug-in generates content and markup according to requirements. By default, popovers are placed behind their triggering elements. You can add a popover in two ways:
Through the data attribute: To add a popover, just add data to an anchor/button tag -toggle="popover" will do. The title of the anchor is the text of the popover. By default, the plugin places the popover at the top.
<a href="#" data-toggle="popover" title="Example popover">
请悬停在我的上面
</a>Via JavaScript: Enable popover via JavaScript:
$('#identifier').popover(options)
Popover plugin Unlike the drop-down menus and other plugins discussed previously, it is not a pure CSS plugin. To use the plugin, you must activate it using jquery (read javascript). Use the following script to enable all popovers on the page:
$(function () { $("[data-toggle='popover']").popover(); });The following example demonstrates the use of the popover plug-in through the data attribute.
