手风琴效果是项目中使用频率较高的一种效果，原来项目一直都在用easyui的，临近年末，试着自己写了一个

css样式

复制代码代码如下:
/* CSS Document */
body {
    margin: 0 auto;
    padding: 0 auto;
    font-size: 9pt;
    font-family: 微软雅黑, 宋体, Arial, Helvetica, Verdana, sans-serif;
}
.accordion {
    padding-left: 0px;
}
.accordion li {
    border-top: 1px solid #000;
    list-style-type: none;
}
.titlemenu {
    width: 100%;
    height: 30px;
    background-color: #F2F2F2;
    padding: 5px 0px;
    text-align: left;
    cursor: pointer;
}
.titlemenu img {
    position: relative;
    left: 20px;
    top: 5px;
}
.titlemenu span {
    display: inline-block;
    position: relative;
    left: 40px;
}
.submenu {
    text-align: left;
    width: 100%;
    padding-left: 0px;
}
.submenu li {
    list-style-type: none;
    width: 100%;
}
.submenu li img {
    position: relative;
    left: 20px;
    top: 5px;
}
.submenu li a {
    position: relative;
    left: 40px;
    top: 5px;
    text-decoration: none;
}
.submenu li span {
    display: inline-block;
    height: 30px;
    padding: 5px 0px;
}
.hover {
    background-color: #4A5B79;
}

自定义js

复制代码代码如下:
(function ($) {
    piano = function () {
        _menu ='[{"title":"一级目录","img":"images/cog.png","submenu":[{"title":"二级目录","img":"images/monitor_window_3d.png"},{"title":"二级目录","img":"images/monitor_window_3d.png"},{"title":"二级目录","img":"images/monitor_window_3d.png"}]},{"title":"一级目录","img":"images/cog.png","submenu":[{"title":"二级目录","img":"images/monitor_window_3d.png"},{"title":"二级目录","img":"images/monitor_window_3d.png"},{"id":"4","title":"二级目录","img":"images/monitor_window_3d.png"}]}]';
        return ep = {
            init: function (obj) {
                _menu = eval('(' + _menu + ')');
                 var li ="";
                $.each(_menu, function (index, element) {
                    li += '<li><div class="titlemenu"><img src=' + element.img + ' width="16" height="16" alt=""/><span>' + element.title + '</span></div>';
                    if(element.submenu!=null)
                    {
                        li+='<ul class="submenu">';
                        $.each(element.submenu, function (ind, ele) {
                            li += '<li><img src=' + ele.img + ' width="16" height="16" alt=""/><span><a href="#">' + ele.title + '</a></span></li>';
                        });
                        li+='</ul>';
                    }
                    li+='</li>';
                });
                obj.append(li);
            }
        }
    }
    $.fn.accordion = function (options) {
        var pia = new piano();
        pia.init($(this));
        return this.each(function () {
            var accs = $(this).children('li');
             accs.each(reset);
            accs.click(onClick);
            var menu_li = $(".submenu").children("li");
            menu_li.each(function (index, element) {
                $(this).mousemove(function (e) {
                    $(this).siblings().removeClass("hover");
                    $(this).find("a").css("color", "#fff");
                    $(this).siblings().find("a").css("color", "#000");
                    $(this).addClass("hover");
                });
            });
        });
    }
    function onClick() {
        $(this).siblings('li').find("ul").each(hide);
        $(this).find("ul").slideDown('normal');
        return false;
    }
    function hide() {
        $(this).slideUp('normal');
    }
    function reset() {
        $(this).find("ul").hide();
    }
})(jQuery);

html调用方式

复制代码代码如下:
<!doctype html>
<html>
<head>
<meta charset="utf-8">
<title>无标题文档</title>
<script src="/UploadFiles/2021-04-02/jquery-1.8.0.min.js"> <link rel="stylesheet" type="text/css" href="style.css">
<script src="/UploadFiles/2021-04-02/accordion.js"> <script type="text/javascript">
    $(function(){
        $("#accordion").accordion();
    });
</script>
</head>
<body>
<ul id="accordion" class="accordion" style="width:200px;height:500px;">
</ul>
</body>
</html>
