当您需要描述链接时，工具提示会很有用。该插件的灵感来自Jason Frame编写的jQuery.tipsy插件。此后，工具提示已更新为可以在没有图像的情况下工作，并带有CSS动画和用于本地标题存储的数据属性。
工具提示插件可按需生成内容和标记，默认情况下将工具提示放置在其触发元素之后。
您可以尝试运行以下代码以在Bootstrap中实现工具提示插件-
<!DOCTYPE html>
<html>
<head>
<title>Bootstrap Example</title>
<link href = "/bootstrap/css/bootstrap.min.css" rel = "stylesheet">
<script src = "/scripts/jquery.min.js"></script>
<script src = "/bootstrap/js/bootstrap.min.js"></script>
</head>
<body>
<div style = "padding: 100px 100px 10px;">
This is a <a href = "#" class = "tooltip-show" data-toggle = "tooltip"
title = "show">Tooltip on method show</a>.
This is a <a href = "#" class = "tooltip-hide" data-toggle = "tooltip"
data-placement = "left" title = "hide">Tooltip on method hide</a>.
This is a <a href = "#" class = "tooltip-destroy" data-toggle = "tooltip"
data-placement = "top" title = "destroy">Tooltip on method destroy</a>.
This is a <a href = "#" class = "tooltip-toggle" data-toggle = "tooltip"
data-placement = "bottom" title = "toggle">Tooltip on method toggle</a>.
<br><br><br><br><br><br>
<p class = "tooltip-options" >
This is a <a href = "#" data-toggle = "tooltip" title = "<h2>'am Header2
</h2>">Tooltip on method options</a>.
</p>
<script>
$(function () { $('.tooltip-show').tooltip('show');});
$(function () { $('.tooltip-hide').tooltip('hide');});
$(function () { $('.tooltip-destroy').tooltip('destroy');});
$(function () { $('.tooltip-toggle').tooltip('toggle');});
$(function () { $(".tooltip-options a").tooltip({html : true });});
</script>
</div>
</body>
</html>
