又一款核心基于jquery的多级导航菜单特效，横向向右依次展开菜单项，当然本菜单并不是完美的，因此没有怎么美化，另外包括子菜单的上级菜单中缺少一个菜单标记，这样用户有时候不知道哪个菜单中含有下级子菜单。不过添加这样一个标记似乎挺简单，你可以自己动手添加吧。 <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"> <html xmlns="http://www.w3.org/1999/xhtml"> <head> <title>jquery多级下拉侧导航amazonmenu</title> <style> .amazonmenu ul { font: normal 12px Verdana; list-style: none; margin: 0; padding: 0; -moz-box-sizing: border-box; -webkit-box-sizing: border-box; box-sizing: border-box; } .amazonmenu ul li { position: static; } .amazonmenu > ul { background: white; border: 1px solid gray; border-radius: 5px; width: 200px; height: 400px; position: relative; } .amazonmenu > ul li a { color: black; display: block; overflow: auto; padding: 10px 0; position: relative; text-decoration: none; text-indent: 10px; } .amazonmenu > ul li.hassub > a::after { border: 5px solid transparent; border-left-color: gray; content: ''; height: 0; position: absolute; right: 5px; top: 35%; width: 0; } .amazonmenu > ul li.hassub.selected > a::after { border-left-color: red; } .amazonmenu ul li a:hover, .amazonmenu ul li.hassub.selected > a { background: lightblue; color: navy; } .amazonmenu ul li > div, .amazonmenu ul li > ul { background: white; border: 1px solid gray; border-radius: 0 8px 8px 0; box-shadow: 2px 2px 2px gray; display: none; font-weight: normal; width: 300px; height: 400px; left: 100%; padding: 10px; position: absolute; top: 0; -webkit-box-sizing: border-box; -moz-box-sizing: border-box; box-sizing: border-box; z-index: 1000; } /* CSS Media queries */ @media screen and (max-width: 480px) { .amazonmenu ul li > div, .amazonmenu ul li > ul { left: 30px; } .amazonmenu > ul li.hassub.selected::after { background: #eee; content: ''; height: 100%; left: 0; opacity: .8; pointer-events: none; position: absolute; top: 0; width: 100%; z-index: 1; } } </style> <script src="daima/css3yuanzhu/jquery-1.9.1.min.js"></script> <script> document.createElement("nav") // for IE var amazonmenu = { defaults: { animateduration: 100, showhidedelay: [100, 100], hidemenuonclick: true }, setting: {}, menuzindex: 1000, touchenabled: !!('ontouchstart' in window) || !!('ontouchstart' in document.documentElement) || !!window.ontouchstart || !!window.Touch || !!window.onmsgesturechange || (window.DocumentTouch && window.document instanceof window.DocumentTouch), showhide:function($li, action, setting){ clearTimeout( $li.data('showhidetimer') ) if (action == 'show'){ $li.data().showhidetimer = setTimeout(function(){ $li.addClass('selected') $li.data('$submenu') .data('fullyvisible', false) .css({zIndex: amazonmenu.menuzindex++}) .fadeIn(setting.animateduration, function(){ $(this).data('fullyvisible', true) }) }, this.setting.showhidedelay[0]) } else{ $li.data().showhidetimer = setTimeout(function(){ $li.removeClass('selected') $li.data('$submenu').stop(true, true).fadeOut(setting.animateduration) var $subuls = $li.data('$submenu').find('.issub').css({display: 'none'}) if ($subuls.length > 0){ $subuls.data('$parentli').removeClass('selected') } }, this.setting.showhidedelay[1]) } }, setupmenu:function($menu, setting){ var $topul = $menu.children('ul:eq(0)') function addevtstring(cond, evtstr){ return (cond)?
