如何在Rails 3.1中创建hoverover弹出窗口[重复]

I have been searching for a way to implement a hover-over popup with no luck. Because it is used on so many sites I thought it would be easy to find instructions, but I am wondering if I am missing something basic. I have looked at qTips2 and a few others, but these seem like way more than I need.

我一直在寻找一种方法来实现一个没有运气的悬停弹出窗口。因为它被用在很多网站上我觉得很容易找到说明书，但我想知道我是否遗漏了一些基本的东西。我看过qTips2和其他几个，但这些看起来比我需要的更多。

I have a Rails 3.1 app and want to display more details when a user hovers over a line in a table. Is this something built into Rails that I am missing, or do I need an add-on?

我有一个Rails 3.1应用程序，并希望在用户将鼠标悬停在表格中的某一行时显示更多详细信息。这是我缺少的Rails内置的东西，还是我需要一个附加组件？

I sure would appreciate someone pointing me in the right direction.

我肯定会感谢有人指点我正确的方向。

Just set the title on your link like this

只需在此链接上设置标题即可

<a title="Some text that will show up when I hover over this link">My link</a>
