更新 [2016 年 4 月 25 日] 现在更好的编写和完全支持的版本具有更多选项和功能,托管在 GitHub.jQRSS
我看到Nathan Strutz 的Selected Answer,但是,jQuery 插件页面链接仍然关闭,并且该站点的主页似乎没有加载。我尝试了其他一些解决方案,发现其中大多数不仅过时,而且 EASY!因此,我把帽子扔在那里并制作了自己的插件,并且这里有死链接,这似乎是提交答案的好地方。如果您在 2012 年(很快到 2013 年)寻找这个答案,您可能会像我一样注意到死链接和旧建议的挫败感。下面是我的 modern 插件示例的链接以及插件的代码!只需将代码复制到 JS 文件中并像任何其他插件一样将其链接到您的标题中。使用非常方便!

2015 年 2 月 9 日 - 在向其发送命令之前检查 console 进行了早该更新!应该有助于解决旧的 IE 问题。

{
count: // default is 10; max is 100. Setting to -1 defaults to 100
historical: // default is false; a value of true instructs the system to return any additional historical entries that it might have in its cache.
output: // default is "json"; "json_xml" retuns json object with xmlString / "xml" returns the XML as String
rss: // simply an alternate place to put news feed link or search terms
userip: // as this uses Google API, I'll simply insert there comment on this:
/* Reference: https://developers.google.com/feed/v1/jsondevguide
This argument supplies the IP address of the end-user on
whose behalf the request is being made. Google is less
likely to mistake requests for abuse when they include
userip. In choosing to utilize this parameter, please be
