在网页制作中我们常常需要折叠式的菜单,在折叠菜单中,手风琴特效的菜单是非常受欢迎,下面就讲解使用jQuery+HTML+CSS3实现垂直手风琴折叠菜单的方法。
jQuery实现垂直手风琴折叠菜单示例代码
首先给出手风琴折叠菜单的HTML代码,如下所示:
<!DOCTYPE html> <html> <head> <meta charset="UTF-8"> <title>CSS3垂直手风琴折叠菜单DEMO演示</title> <meta name="viewport" content="width=device-width, initial-scale=1"> <!-- Iconos --> <link href="css/font-awesome.min.css" rel="stylesheet"> <link rel="stylesheet" href="css/style.css" media="screen" type="text/css" /> </head> <body> <!-- 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"> <li><a href="#">Photoshop</a></li> <li><a href="#">HTML</a></li> <li><a href="#">CSS</a></li> <li><a href="#">Maquetacion web</a></li> </ul> </li> <li> <div class="link"><i class="fa fa-code"></i>Desarrollo front-end<i class="fa fa-chevron-down"></i></div> <ul class="submenu"> <li><a href="#">Javascript</a></li> <li><a href="#">jQuery</a></li> <li><a href="#">Frameworks javascript</a></li> </ul> </li> <li> <div class="link"><i class="fa fa-mobile"></i>Diseño responsive<i class="fa fa-chevron-down"></i></div> <ul class="submenu"> <li><a href="#">Tablets</a></li> <li><a href="#">Dispositivos mobiles</a></li> <li><a href="#">Medios de escritorio</a></li> <li><a href="#">Otros dispositivos</a></li> </ul> </li> <li><div class="link"><i class="fa fa-globe"></i>Posicionamiento web<i class="fa fa-chevron-down"></i></div> <ul class="submenu"> <li><a href="#">Google</a></li> <li><a href="#">Bing</a></li> <li><a href="#">Yahoo</a></li> <li><a href="#">Otros buscadores</a></li> </ul> </li> </ul> <script src=‘js/jquery.js‘></script> <script src="js/index.js"></script> </body> </html>
如上面的代码,首先需要引入font-awesome.min.css,这是awesome的字体库。然后需要引入自定义的css,style.css代码如下面所示:
* { 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 ===========================*/ h1 { color: #FFF; font-size: 24px; font-weight: 400; text-align: center; margin-top: 80px; } h1 a { color: #c12c42; font-size: 16px; } .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); } /** * 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; }
使用jQuery&HTML&CSS3实现垂直手风琴折叠菜单就必须使用jQuery,所以一定要引入jQuery库。然后配合自定义的js,index.js代码如下所示:
$(function() { 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) } 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‘); }; } var accordion = new Accordion($(‘#accordion‘), false); });
这样我们可以看到下面的图片效果:
