The :visitedpseudo-class works on the browser's history. The fact that all three links are being drawn with the black colour means that your browser has visited them in the past. If you were to clear your history, or change the links' urls, you'll find that they aren't classed as 'visited'.
该:visited伪类适用于浏览器的历史。所有三个链接都用黑色绘制的事实意味着您的浏览器过去曾访问过它们。如果您要清除历史记录或更改链接的 url，您会发现它们并未归类为“已访问”。
A link to StackOverflowwill probably show as visited in your browser, but a link to Voice of JIHADprobably shows up a different colour (unless you are a member of the Taliban). Clicking on the unvisited link will change its colour to the visited colour - as defined in StackOverflow's stylesheets - and will remain 'visited' as long as the page exists in your browser's history.
指向 StackOverflow的链接可能会在您的浏览器中显示为已访问，但指向“圣战之声”的链接可能会显示不同的颜色（除非您是塔利班成员）。单击未访问的链接会将其颜色更改为已访问的颜色（如 StackOverflow 的样式表中所定义），并且只要该页面存在于浏览器的历史记录中，就会保持“已访问”状态。

Ok, so now you know that :visitedworks from the browser history, and I think you want to change the color of the clicked link only.
I put some jQuery together
好的，现在您知道:visited浏览器历史记录有效，我认为您只想更改单击链接的颜色。我把一些 jQuery 放在一起
$('a').click(function(){
$(this).addClass("visited");
});
and the CSS
和 CSS
a{
color:#000;
text-decoration:none;
}
a.visited{
color:#205081;
}
