HTML结构

html结构使用无序列表,每一个列表项作为一个菜单项使用。

<!-- Contenedor -->
<ul id="accordion" class="accordion">
    <li>
        <div class="link"><i class="fa fa-paint-brush"></i>Diseño web<i class="fa fa-chevron-down"></i></div>
        <ul class="submenu">

CSS样式

下面来给手风琴折叠菜单添加一些样式。

* {
    margin: 0;
    padding: 0;
    -webkit-box-sizing: border-box;
    -moz-box-sizing: border-box;
    box-sizing: border-box;
}
body {
    background: #2d2c41;
    font-family: 'Open Sans', Arial, Helvetica, Sans-serif, Verdana, Tahoma;
}
ul {
    list-style-type: none;
} 
a {
    color: #b63b4d;
    text-decoration: none;
}
/** =======================
 * Contenedor Principal
 ===========================*/
.accordion {
    width: 100%;
    max-width: 360px;
    margin: 30px auto 20px;
    background: #FFF;
    -webkit-border-radius: 4px;
    -moz-border-radius: 4px;
    border-radius: 4px;
 }
.accordion .link {
    cursor: pointer;
    display: block;
    padding: 15px 15px 15px 42px;
    color: #4D4D4D;
    font-size: 14px;
    font-weight: 700;
    border-bottom: 1px solid #CCC;
    position: relative;
    -webkit-transition: all 0.4s ease;
    -o-transition: all 0.4s ease;
    transition: all 0.4s ease;
}
.accordion li:last-child .link {
    border-bottom: 0;
}
.accordion li i {
    position: absolute;
    top: 16px;
    left: 12px;
    font-size: 18px;
    color: #595959;
    -webkit-transition: all 0.4s ease;
    -o-transition: all 0.4s ease;
    transition: all 0.4s ease;
}
.accordion li i.fa-chevron-down {
    right: 12px;
    left: auto;
    font-size: 16px;
}
.accordion li.open .link {
    color: #b63b4d;
}
.accordion li.open i {
    color: #b63b4d;
}
.accordion li.open i.fa-chevron-down {
    -webkit-transform: rotate(180deg);
    -ms-transform: rotate(180deg);
    -o-transform: rotate(180deg);
    transform: rotate(180deg);
}
                

下面是子菜单的CSS样式:

/**
 * Submenu
 -----------------------------*/
 .submenu {
    display: none;
    background: #444359;
    font-size: 14px;
 }
 .submenu li {
    border-bottom: 1px solid #4b4a5e;
 }
 .submenu a {
    display: block;
    text-decoration: none;
    color: #d9d9d9;
    padding: 12px;
    padding-left: 42px;
    -webkit-transition: all 0.25s ease;
    -o-transition: all 0.25s ease;
    transition: all 0.25s ease;
 }
 .submenu a:hover {
    background: #b63b4d;
    color: #FFF;
 }
                

现在,你看到的手风琴折叠菜单的样子如下图所示:

手风琴折叠菜单

JAVASCRIPT

首先定义Accordion对象:

var Accordion = function(el, multiple) {
    this.el = el || {};
    this.multiple = multiple || false;

    // Variables privadas
    var links = this.el.find('.link');
    // Evento
    links.on('click', {el: this.el, multiple: this.multiple}, this.dropdown)
}
                

为手风琴Accordion添加下拉菜单事件:

Accordion.prototype.dropdown = function(e) {
    var $el = e.data.el;
        $this = $(this),
        $next = $this.next();
 
    $next.slideToggle();
    $this.parent().toggleClass('open');
 
    if (!e.data.multiple) {
        $el.find('.submenu').not($next).slideUp().parent().removeClass('open');
    };
}
                

然后可以通过下面语句调用手风琴下拉菜单:

var accordion = new Accordion($('#accordion'), false);
