jQuery-可折叠的模式-优快云博客

本文介绍了一种使用jQuery实现的手风琴效果，通过简单的HTML结构配合jQuery代码，能够使页面上的多个标题及其对应的内容区域折叠或展开，提供良好的交互体验。

jQuery:

<script src="Scripts/jquery-1.4.1.js" type="text/javascript"></script>
    <script type="text/javascript" language="javascript">
        $(document).ready(function () {

            $(".accordion h3:first").addClass("active");
            $(".accordion p:not(:first)").hide();

            $(".accordion h3").click(function () {
                $(this).next("p").slideToggle("slow")
        .siblings("p:visible").slideUp("slow");
                $(this).toggleClass("active");
                $(this).siblings("h3").removeClass("active");
            });

        });
    </script>

HMTL:

<div class="accordion">
        <h3 class="">
