一、HTML
<div id="demo"> <span class="icon-menu" id="icon"></span> <ul class="nav"> <li>首页</li> <li>前端开发 <ul class="submenu"> <li>HTML-CSS</li> <li>JQuery</li> <li>JavaScript</li> </ul> </li> <li>后端开发 <ul class="submenu"> <li>PHP</li> <li>Python</li> <li>Ruby</li> </ul> </li> <li>移动开发 <ul class="submenu"> <li>Android</li> <li>IOS</li> </ul> </li> <li>编程语言 <ul class="submenu"> <li>C-C++</li> <li>Java</li> </ul> </li> <li>业界分享</li> <li>开发平台 <ul class="submenu"> <li>Linux-Vim</li> <li>Git</li> </ul> </li> </ul> </div>
二、CSS
#demo{ margin: 0 auto; padding: 0; } ul{ list-style: none; } ul.nav{ list-style: none; font-family: "Microsoft Yahei" } ul.nav li{ height: 20px; color: #ffffff; cursor: pointer; line-height: 20px; background-color: #67544D; padding: 15px; } @media screen and (min-width: 844px){ #demo{ width: 845px; } #icon{ display: none; } ul.nav>li{ display: inline-block; margin-left: 15px; position: relative; } ul.submenu{ position: absolute; z-index: 99; top: 50px; left: -20px; width: 64px; display: none; margin-left: 15px } ul.submenu li{ width: 100%; margin-left: -35px; line-height: 100%; text-align: center; } } @media screen and (max-width:843px){ #demo{ position: relative; } #icon{ display: inline-block; font-size: 20px; position: relative; } ul.nav{ width: 100%; position: relative; top: -18px; left: 0; display: none; } ul.nav>li{ margin-left: -40px; position: relative; height: auto; } ul.submenu{ display:none; color: white } .shownav{ display: block; } }
三、js
$(function(){ $(‘.nav>li‘).each(function() { $(this).on({ mouseover:function(){ $(this).css({backgroundColor:"#48403D",color:"#ACE360"})
.find("ul").slideDown(500). find("li").each(function(){ $(this).hover( function() { $(this).css({backgroundColor:"#48403D",
color:"#ACE360"}); }, function(){ $(this).css({backgroundColor:"#67544D",
color:"#FFFFFF"}); }); }); }, mouseleave:function(){ $(this).find("ul").css("display","none").stop(true); }, mouseout:function(){ $(this).css({backgroundColor:"#67544D",
color:"#FFFFFF"}); } }); }); /*toggleClass不起作用?????*/ var count = 1; $("#icon").on("click",function(){ if(count == 1){ $("ul.nav").css("display","block"); count++; } else{ $("ul.nav").css("display","none"); count=1; } })
