我在我的页面上使用jQuery按钮。每当我点击其中一个按钮时，Internet Explorer就会添加一个丑陋的黑色边框，因为该按钮处于活动状态。当我皱眉头时http://jqueryui.com/demos/button/“rel=”nofollow“>jQuery按钮示例页使用IE，当我单击其中一个示例按钮时，此边框不可见。
为什么不呢？他们如何避开这条边界？我检查了他们的CSS文件，但找不到任何东西。。。
禁用该边界的唯一方法是使用CSS过滤器（这不是有效的CSS）：
button { filter:chroma(color=#000000); }
也许有更好的解决方案？
你的CSS中还有其他可能导致这种情况的东西吗？如果它没有出现在示例页面上，那么是您的标记/css/javascript中的某些内容导致了它。
试着只使用中的按钮制作一个孤立的示例，并添加所有其他CSS，直到找到原因为止。
使用这个CSS过滤器要小心。这将导致IE8中的副作用——单选按钮内的子弹将变得不可见。因此，从视觉上看，尽管单选按钮操作正常，但它们似乎无法工作。
