我根据在网上找到的教程创建了一个菜单，我希望能更进一步。我想让每个链接完全更改为单击时指定的背景颜色。我尝试使用 a:active 但这似乎不起作用。这是我到目前为止所拥有的，也许我需要使用一些 J-Query？这是小提琴和代码

<div style="width: 1000px; margin: 0 auto; text-align:center; ">
<ul id="menu">
<li><a class="anchor" href="#welcomeanchor">Home</a></li>
<li><a class="anchor" href="#aboutusanchor">About Us </a></li>
<li><a class="anchor" href="#classesanchor">Classes </a> </li>
<li><a class="anchor" href="#scheduleanchor">Schedule</a></li>
<li><a class="anchor" href="#newsanchor">News</a></li>
<li><a class="anchor" href="#programsanchor">Programs</a></li>
<li><a class="anchor" href="#contactanchor">Contact</a></li>
</ul></div>

尝试这个

在 Js 中

 $(document).ready(function(){
    $(".anchor").click(function(){
       $(".anchor").each(function(){
          $(this).parent("li").css("background","#000")
       })
       var color1 = $(this).css("border-color");
       $(this).parent("li").css("background",color1);
    })
 })

有点玩这个。

jQuery 解决方案

$('.anchor').click(function(){
    $('.active').removeClass('active');
    $(this).addClass('active');
});

您只需要将活动类添加到您的 CSS。http://jsfiddle.net/bplumb/EDZ8F/7/

纯 CSS 解决方案

更具挑战性和局限性。:target我创建了一个使用psudeo 类可以做什么的示例。

http://jsfiddle.net/bplumb/EDZ8F/6/

的HTML

<div style="width: 1000px; margin: 0 auto; text-align:center; ">
    <ul id="menu">
        <li id="welcomeanchor"><a class="anchor" href="#welcomeanchor">Home</a>
            <div><p>Home Content</p></div>     
        </li>
        <li id="aboutusanchor"><a class="anchor" href="#aboutusanchor">About Us </a>
             <div><p>About Us Content</p></div>
        </li>
        <li id="classesanchor"><a class="anchor" href="#classesanchor">Classes </a> 
            <div><p>Classes Content</p></div>
        </li>
        <li id="scheduleanchor"><a class="anchor" href="#scheduleanchor">Schedule</a>
            <div><p>Schedule Content</p></div>
        </li>
        <li id="newsanchor"><a class="anchor" href="#newsanchor">News</a>
            <div><p>News Content</p></div>
        </li>
        <li id="programsanchor"><a class="anchor" href="#programsanchor">Programs</a>
            <div><p>Programs Content</p></div>
        </li>
        <li id="contactanchor"><a class="anchor" href="#contactanchor">Contact</a>
            <div><p>Contact Content</p></div>
        </li>
    </ul>
</div>

您可以为每个元素指定活动

演示http://jsfiddle.net/kevinPHPkevin/EDZ8F/2/

li:nth-child(1) a:active {
color: #fff;
}
li:nth-child(2) a:active {
color: #ff6;
}
li:nth-child(3) a:active {
    color:#f60;
}
li:nth-child(4) a:active {
    color:#00f;
}
