唷，这需要一些调试。
问题是，Illumination 假设 jQuery 不支持 box-shadow 属性，但较新的 jQuery 版本支持。这意味着当供应商前缀不可用（它们不在最新的 FireFox 中）时，您将获得无限循环或未定义的属性。幸运的是，Illumination 使用了一个未定义的属性BoxShadow，而不是使用了无限循环boxShadow（正如我发现的那样，这导致了几次浏览器挂起）。
所以这就是问题所在，解决方法是什么？从照明中删除有问题的代码。support.boxShadow应将所有情况更改为 simple 'boxShadow'，并cssHooks.boxShadow删除该块。您还可以删除support.boxShadow首先设置的位。
我的测试用例在这里：http: //jsfiddle.net/JbTcs/2/并且在 FireFox 和 Chrome 中工作，我被告知 IE10。照明的固定源代码是：
