这里是css代码

    * {     margin: 0;        padding: 0;        font: 14px "simsun";    }    a{        color: #333;        text-decoration: none;    }    a:hover{        color:#c81623;    }    ul {        list-style: none;    }    .father {        width: 600px;        height: 400px;        margin: 100px auto;    }    .top {        height: 30px;        border-bottom: 1px solid #c81623;    }    .tabs {        height: 30px;        border: 1px solid #dddddd;        border-bottom: 0 none;        float: right;    }    .tab {        float: left;        position: relative;    }    li.tabCurrent {        background-color: #fff;        height: 27px;        border-top: 3px solid #c81623;        border-left: 1px solid #c81623;        border-right: 1px solid #c81623;    }    li.tabCurrent a {        line-height: 27px;        padding: 0 13px;    }    .tab a {        display: block;        padding: 0 14px;        height: 30px;        line-height: 30px;    }    .tab .line {        height: 20px;        border-left: 1px solid #ddd;        position: absolute;        right: 0;        top: 5px;    }    .goods {        width: 598px;        height: 368px;        border: 1px solid #dddddd;        border-top: 0 none;        display: none;        text-align: center;        line-height: 300px;    }    div.goodsShow{        display: block;    }

这里是js代码

var tabs = document.getElementsByTagName("li");        var goods = document.getElementsByName("content");        for (var i = 0; i < tabs.length; i++) {            tabs[i].index = i;            tabs[i].onmouseover = function(){                for (var j = 0; j < tabs.length; j++) {                    var cn = tabs[j].className;                    if(cn.indexOf("tabCurrent")){                        tabs[j].className = cn.replace("tabCurrent","");                    }                }                var className = this.className;                this.className = className.concat(" tabCurrent");                for (var k = 0; k < goods.length; k++) {                    goods[k].style.display = "none";                }                goods[this.index].style.display = "block";            }        }
