请帮助我完成以下代码。我可以使用图像创建循环菜单，并使其对我来说很简单，但我想使用CSS和Jquery使页面变得超级快速，并从这个项目中学到一些东西。我想做的是更改（设置动画）悬停菜单项周围的圆形的颜色。我认为代码非常自我解释，但如果有什么不清楚的地方，请告诉我。

您需要在此处查看jQuery UI颜色动画。
通过包含此脚本标记，您可以使用google CDN包含jQuery UI。
<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery-ui/1.8.21/jquery-ui.min.js"></script>
基本上，它可以归结为链接jQueryUI，然后将悬停函数更改为mouseenter函数。
看看这个工作示例。
看看这个：http://jsfiddle.net/ufomammut66/ZsX8e/
我已将您的悬停事件更改为鼠标输入事件。如果您将其改回悬停在jsfiddle中，您会注意到"in"日志记录语句在退出时会触发两次（查找我留下的console.log语句），这是我们不希望的。
我还将jquery选择器更改为您的circle类。我这样做是因为你似乎看不到li元素（这可能只是缺少图像），你希望它在进入圆形元素时激发。
我不清楚你试图使用itemnumber做什么，但似乎你试图重建圆形元素ID来选择它。我们不需要这样做，因为this元素将指代我们正在进入或离开的当前元素。
注意：我认为您使用的是：http://www.bitstorm.org/jquery/color-animation/作为您的jquery.color.min.js导入。jsFiddle已将其导入工作。
希望这能有所帮助。
