原生js和jQuery写的网页选项卡特效对比

总的来说思路比较简单，就是先获取节点，然后对节点进行相应的处理,下面是完整的页面代码：
原生js：

<！DOCTYPE html><html><head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>原生js tab</title><style type="text/css">.tab{margin:10px auto;position:relative;width:300px;}ul,li{list-style-type:none;padding:0;margin:0;font:13px/20px SimSun,arial;color:#333;text-align:center;}.tabTltle ul li{ float:left; position:relative; background:#fefefe; background:-webkit-gradient（linear,left top,left bottom, from（#fefefe）, to（#ededed））; padding:7px 15px; border:1px #ddd solid; margin-right:-1px; cursor:pointer;}.tabTltle ul li.active{background:#fff;font-weight: bold;}.clearfix{}.clearfix:after{display:block;clear:both;overflow:hidden;content:"";}.tabConn{border:1px #eee solid;position:relative;height:100px}.tabConn div{position:absolute;opacity:0;filter:alpha（opacity=0）;padding:5px;text-align:center;width:100%;}.tabConn div.current{opacity:1;filter:alpha（opacity=100）;}</style></head><body><div id="tab" class="tab"><div class="tabTltle"><ul class="clearfix"><li class="active">标题一</li><li>标题二</li><li>标题三</li><li>标题四</li></ul></div><div class="tabConn"><div class="current">aaaaaaaaaaaaaaa</div><div>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb</div><div>cccccccccccccccccccccccccccccccc</div><div>ddddddddddddddddddddddddddddd</div></div></div><script type="text/javascript"> （function（）{ var tab = document.getElementById（"tab"）; var tabList = tab.getElementsByTagName（"div"）[0].getElementsByTagName（"li"）; var tabConn = tab.getElementsByTagName（"div"）[1].getElementsByTagName（"div"）;for（var i=0;i<tabList.length;i++）{tabList[i].index = i;tabList[i].onclick = function（）{showConn（this.index）;}}function showConn（_index）{var index = _index;for（var j=0;j<tabList.length;j++）{tabList[j].className = "";tabConn[j].className = "";tabConn[j].style.opacity=0;}tabConn[index].className="current";tabList[index].className="active";} }）（）;</script></body></html>

下面我们来看一下jQuery写的（css共用,需要引进jQuery库）：

<！DOCTYPE html><html><head><meta charset="utf-8"><meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1"><title>jQuery tab</title><script type="text/javascript" src="js/jquery-1.8.1.min.js"></script><style type="text/css">.tab{ margin:10px auto; position:relative; width:300px;}ul,li{ list-style-type:none; padding:0; margin:0; font:13px/20px SimSun,arial; color:#333; text-align:center;}.tabTltle ul li{ float:left; position:relative; background:#fefefe; background:-webkit-gradient（linear,left top,left bottom, from（#fefefe）, to（#ededed））; padding:7px 15px; border:1px #ddd solid; margin-right:-1px; cursor:pointer;}.tabTltle ul li.active{ background:#fff; font-weight: bold;}.clearfix{}.clearfix:after{ display:block; clear:both; overflow:hidden; content:"";}.tabConn{ border:1px #eee solid; position:relative; height:100px}.tabConn div{ position:absolute; opacity:0; filter:alpha（opacity=0）; padding:5px; text-align:center; width:100%;}.tabConn div.current{ opacity:1; filter:alpha（opacity=100）;}</style></head><body><h3>jQuery写的选项卡:</h3> <div id="tab2" class="tab"><div class="tabTltle tab-title"> <ul class="clearfix"><li class="active">标题一</li><li>标题二</li><li>标题三</li><li>标题四</li> </ul></div><div class="tabConn tab-conn"> <div class="current">aaaaaaaaaaaaaaa</div> <div>bbbbbbbbbbbbbbbbbbbbbbbbbbbbbb</div> <div>cccccccccccccccccccccccccccccccc</div> <div>ddddddddddddddddddddddddddddd</div></div> </div><script type="text/javascript">$（document）.ready（function（）{ var $tabTitle = $（".tab-title"）.find（"li"）; var $tabList = $（".tab-conn > div"）; $tabTitle.click（function（）{$tabTitle.each（function（）{ $tabTitle.removeClass（"active"）;}）;var index = $tabTitle.index（this）;$（this）.addClass（"active"）; $tabList.eq（index）.addClass（"current"）.siblings（）.removeClass（"current"）; }）;}）;</script></body></html>

是不是简单了好多！
