jQuery Tooltip 插件取代了原生的工具提示框，让它们可自定义，您只需要调整它们的内容、位置和外观即可。
该插件目前版本是 1.3，已经很长时间没有更新，推荐使用 jQuery UI 工具提示框（Tooltip）。
如需了解更多有关 jQuery UI 工具提示框（Tooltip）的细节，请查看 API 文档 jQuery UI 工具提示框部件（Tooltip Widget）。

| <p><a href="#" title="That's what this widget is">Tooltips</a> can be attached to any element. When you hover |
| the element with your mouse, the title attribute is displayed in a little box next to the element, just like a native tooltip.</p> |
| <p>But as it's not a native tooltip, it can be styled. Any themes built with |
| <a href="http://jqueryui.com/themeroller/" title="ThemeRoller: jQuery UI's theme builder application">ThemeRoller</a> |
| will also style tooltips accordingly.</p> |
| <p>Tooltips are also useful for form elements, to show some additional information in the context of each field.</p> |
| <p><label for="age">Your age:</label><input id="age" title="We ask for your age only for statistical purposes."></p> |
| <p>Hover the field to see the tooltip.</p> |
