如何在JavaScript中获得对当前焦点表单字段的引用？(How to get a reference to the currently focused form field in JavaScript?)

我正在寻一种跨浏览器的方法 - 我知道IE有一些东西（我已经忘记了它），在Mozilla中这样做的方式可能与我发现的focusode有关，这似乎与获取文本有关选择。

涉及jQuery或其他常见JS库的方法对我来说很好。

谢谢！

I'm looking for a cross-browser method - I know IE has something (I've already forgotten what), and the way to do it in Mozilla may have to do with a focusode thing I found, that seems related to getting text selecti.

Methods involving jQuery or another common JS library are fine by me.

Thanks!

查看jQuery的额外选择器插件 ，它包含一个:focus选择器，可以满足您的需求。 如果没有其他选择，您可以只使用该选择器的实现。

Check out the extra selectors plugin for jQuery, it includes a :focus selector that answers your need. You can use just the implementation of that selector if you don't the rest.
