访问链接颜色不变在IE 8 [英] Visited Links color not changing in IE 8

问题描述

我有一个问题，IE 8的访问链接颜色不会改变我们的应用程序。

我们没有这个问题与IE6。
当使用IE6时，如果以前已经查看链接，已访问链接会更改其颜色。
我们的应用程序适用于IE6，但是IE8的访问链接不会改变其颜色。

有关信息，
我已清除历史记录，未选中浏览器选项中的使用Windows颜色选项。

这里是CSS：

  a：link {
 color：＃006000; 
} 
 
 a：visited {
 color：＃3CB371; 
} 
  

任何帮助和建议将非常感谢。

解决方案

：访问样式存在安全问题。

简要描述一下，恶意网站可能通过链接到所有要检查的网站来查找您访问的网站，然后只检查这些链接的颜色。

这个问题在三年前得到了大量的宣传，结果IE和所有其他浏览器发布了禁用的补丁：访问了样式。

我找不到特定于IE的链接，但这里有一个来自Mozilla 在Firefox 中描述问题及其解决方案。 / p>

旧版浏览器（IE6，IE7）仍然支持：visited 样式，但IE8和所有其他当前浏览器不是。

其中一些支持它作为用户可配置的选项，但默认关闭，但很少有用户将其打开，所以你可以基本上忽略它。

最近，一些浏览器重新启用了风格，但改变了Javascript getComputedStyle（）函数，使其忽略访问样式。这允许最终用户看到访问的颜色，但防止黑客找到信息的可能性。我不认为IE8有这个更新。

I am having a problem with IE 8 where the visited links color do not change in our application.

We don’t have this problem with IE6. When using IE6, visited links changes its color if the link has been viewed before. Our application works fine with IE6 but with IE8 the visited link do not changes its color.

For information, I have cleared the history , unchecked the option "use Windows Colors" in the browser option. But the links in our application always remain unvisited.

Here is the CSS:

a:link {
    color : #006000;
}

a:visited {
    color : #3CB371;
}

Any help and suggestions would be greatly appreciated.

解决方案

There is a security issue with the :visited style.

To describe it briefly, it is possible for a malicious site to find out what sites you've visited by having links to all the sites it wants to check for, and then just examining the colours of those links.

This issue got a lot of publicity about three years ago, and as a result IE and all the other browsers released patches that disabled the :visited style.

I couldn't find a link that was specific to IE, but here's a link from Mozilla describing the problem and their solution for it in Firefox.

Older browsers (IE6, IE7) will still support the :visited style, but IE8 and all other current browsers do not.

Some of them do support it as a user-configurable option, but defaulting to switched off, but very few users will have switched it on, so you can basically ignore that.

More recently, some browsers have re-enabled the style, but changed the Javascript getComputedStyle() function so that it ignores the visited style. This allows the end user to see the visited colour but prevents the potential for a hacker to find out the information. I don't think IE8 ever got this update.
