本文實(shí)例中主要是通過(guò)判斷點(diǎn)擊菜單在菜單列表中的索引位置來(lái)顯示或隱藏選項(xiàng)區(qū).原生js還有很多種實(shí)現(xiàn)方法(藍(lán)色理想中搜索),為了與jQ版思路保持一致,本文實(shí)例用的是循環(huán)判斷.有需要的小伙伴可以參考下

總的來(lái)說(shuō)思路比較簡(jiǎn)單，就是先獲取節(jié)點(diǎn)，然后對(duì)節(jié)點(diǎn)進(jìn)行相應(yīng)的處理,下面是完整的頁(yè)面代碼：

原生js：

(function(){

function showConn(_index){

tabConn[index].className="current";

tabList[index].className="active";

}

})();

</script>

</body>

下面我們來(lái)看一下jQuery寫(xiě)的(css共用,需要引進(jìn)jQuery庫(kù))：

<!DOCTYPE html>

<html>

<meta charset="utf-8">

<meta http-equiv="X-UA-Compatible" content="IE=edge,chrome=1">

<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>
