我想将与悬停时相同的样式应用于活动选项卡（请参阅代码）。我是 jQuery 新手，有人可以看看吗？

目前，只有悬停效果有效，但我希望活动标签保持白色并具有黑色文本。

<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>Untitled Document</title>

<body>
<style type="text/css">
body {
height: 600px
}

h1 {
color: #CC0000;
font-family: arial;
font-size: 18px
}

a.examples {color:#CCCCCC}
a.examples:hover {color:black}

#tabs ul {

您正在添加一个类active，但该类没有 css 规则。

#tabs ul li.active a{color:black}

尝试

Fiddle DEMO

js具有所需结果的脚本的 jQuery 版本。

$(document).ready(function () {
    $('#tabs li[id^="li_tab"]').click(function () {
        $(this).addClass('active').siblings().removeClass('active');
        var id = this.id.replace('li_', '');
        $('#' + id).show().siblings('div[id^=tab]').hide();
    });
});

css

#tabs ul li.active a {
    color:black
}
#tabs ul li.active{
    background-color:white;
}
