<script type="text/javascript">
/*-------------------以后常用-----下面的------------------------*/
function huan(a)
{    
    //将所有的項回复原样式
    var d=document.getElementsByClassName("xiang");
    for(var i=0;i<d.length;i++)
    {
        d[i].style.backgroundColor="white";
        d[i].style.color="black";
    }
    
    //换该元素的样式   鼠标移上去换色
    a.style.backgroundColor="red";
    a.style.color ="white";

<!-------------------第二种方式也可以实现效果-------------------------------------->
