以下是我使用过的代码。默认选项卡是tab1，为红色。选择第二个选项卡时，第一个选项卡仍处于活动状态。选择第二个选项卡时如何删除第一个选项卡颜色http://jsfiddle.net/JE3e5/12/
<ul class="rtabs">
<li class="active-first"rel="tab1"> <span>Tab1</span></li>
<li rel="tab2"> <span>Tab2</span></li>
<li rel="tab3"><span> Tab3</span></li>
<li rel="tab4" class="last"> <span>Tab4</span></li>
</ul>
<div class="tab_container">
<div id="tab1" class="tab_content">
<p><img src="images/cod.jpg"> <br />

}
jquery的
$(document).ready(function() {
$(".tab_content").hide();
$(".tab_content:first").show();
$("ul.rtabs li").click(function() {
$("ul.rtabs li").removeClass("active");
$(this).addClass("active");
$(".tab_content").hide();
var activeTab = $(this).attr("rel");
$("#"+activeTab).fadeIn();
});
});
