Question

请帮我处理以下代码。我可以使用图像来创建圆形菜单并让它变得简单，但我想使用CSS和Jquery使页面超级快速，并从这个项目中学到一些东西。我想要做的是更改（动画）悬停菜单项周围的圆形形状的颜色。我认为代码非常自我解释，但如果有什么不清楚，请告诉我。

Answer 1

您需要查看jQuery UI Color动画here。

您可以通过添加此脚本标记来使用google CDN添加jQuery UI。

<script type="text/javascript" src="https://ajax.googleapis.com/ajax/libs/jquery-ui/1.8.21/jquery-ui.min.js"></script>

基本上它归结为链接jQuery UI，然后将你的悬停功能更改为mouseenter函数。

查看此working example。

Answer 2

看看：http://jsfiddle.net/ufomammut66/ZsX8e/

我将您的悬停事件更改为mouseenter事件。如果你把它改回来悬停在jsfiddle中，你会注意到'in'logging语句会在出路时触发两次（查找我留下的console.log语句），这是我们不想要的。

我还将jquery选择器更改为您的circle类。我这样做是因为看起来好像你看不到li元素（可能只是缺少图像）你想要它在进入圆形元素时触发。

我不清楚您尝试使用itemnumber，但似乎您正在尝试重建圆元素ID以选择它。我们不需要这样做，因为this元素将引用我们正在进入或离开的当前元素。

注意：我假设您使用此http://www.bitstorm.org/jquery/color-animation/作为jquery.color.min.js导入。 jsFiddle导入了这个。

希望这有帮助。
