我正试图从http://www.makemineatriple.com/2007/10/bbcnewsticker
实现这个jQuery新闻自动收报机样式插件就像评论中提到的那样（5月左右）有一个错误，作者失去了修复错误的意愿。
错误是：
在Mac浏览器（Firefox，Opera和Safari，所有OSX）中 - 链接（一个href）在每个列表项完成滚动/显示之前不“工作”。基本上，在加载此插件后，所有a href都停止工作。
以下是插件的代码（http://plugins.jquery.com/project/BBCnewsTicker）：

任何解决方案？我不是程序员，所以如果有人能指出在哪里修补它非常感谢！
更新： 似乎只有链接？标记变为禁用。

我碰巧碰到过这篇文章。我仍然支持自动收报机，自去年7月以来已有一些版本。
缓解此问题的方法是，现在有一个“停止悬停”选项，当用户将鼠标悬停在其上时（包括当然即将点击它），该选项会暂停自动收报机并完成（立即）项目的显示）。
如果这仍然与您有关，如果您仍然遇到最新版本的问题，则值得通过评论主题阅读;如果你还有问题，请联系我们（如果其中一条评论是你的，我错过了，那么对不起！）。 “官方”方式是在jQuery插件网站上发布错误报告，该报告完全跟踪任何报告的问题，但我确实尝试回复通过博客请求支持的任何人。

如果您的文档中有任何ID为news的元素，可能会发生冲突......这可能是这种情况吗？我会在你的html文档中搜索id="news"的任何出现并更正它们，看到好像将适当的参数传递给插件可能需要一些额外的研究。
