IE8焦点伪类和兄弟选择器

Mat*_*orn 4 css cross-browser css-selectors internet-explorer-8

我有一些标记,当试图文本输入具有焦点时,我试图让"某些输入的提示"亮起.我试图使用焦点伪类和兄弟选择器.如果我只使用一个或另一个它工作得很好.但是,当它们在IE8中组合时,它会突然显示,当您在文本框中进行选项卡时,该样式不会更新.注意:如果您单击文本框并返回它们,则会更新它们的样式.

这是标记:

根据http://www.quirksmode.org/css/contents.html IE浏览器不能正确支持相邻的兄弟选择器,基于此我恐怕我必须说 - 抱歉,你不能使用CSS 实现你想要的东西.

但你可以使用jQuery,这就是你可以这样做的方法:

在我的解决方案中,我包含了对Microsoft托管的jQuery的引用,并编写了简单的方法来应用您需要的样式.您可以通过修改CSS类来轻松修改提示和输入框的"突出显示"状态.

我已经在IE6,IE7,IE8,Firefox,Opera,Chrome和Safari上测试了我的解决方案,它运行正常.
