javascript - 在 Internet Explorer 8 中看不到 CSS 菜单(潜在的 JavaScript 问题？)

Question

我不断收到有关此菜单栏在 Internet Explorer 8 中无法正常运行的投诉。我完全不知道这段代码有什么问题，因为它适用于所有其他浏览器以及早期版本的 IE。

这是网站:

http://www.iirusa.com/centrallab

您可以在此处查看 CSS: http://www.iirusa.com/ed/4999/css/main.css

这是我的菜单代码:

    <script src="/upload/wysiwyg/AC_RunActiveContent.js" type="text/javascript>
    </script>
    <DIV id="header"><a href="/centrallab/home-page.xml"><img src="http://www.iirusa.com/upload/wysiwyg/2011-P-Div/P1625/P1625_Central_Labs_East.jpg" alt="Central Labs East" width="930" height="206" border="0" /></a></DIV>

我唯一能想到的另一个问题是我们引用的 JS 有问题，可以在这里找到:http://www.iirusa.com/upload/wysiwyg/AC_RunActiveContent.js

如果你能帮上忙，请告诉我!将不胜感激，并会让数小时的挫败感变得值得!!

Answer 1

它的 IE6 不是 IE8。问题是 IE6 不支持 :hover 选择器和 a 标签
