解决方案 »

  1.   

    是js的错误,我写的程序全在上面了
    写了js但不出效果!!!
      

  2.   

    先说说什么错误啊~~"switchTo(rm);和"switchTo(jl);都没用 不过还是不知道你要做成什么样子？？tab页切换？？
      

  3.   

     function switchTo(tab){
            var pic = document.getElementById('pic');
            if(tab.name(/*或其他什么，记不得了*/)=="sc"){
                qytab = docment.getElementById('qytab');
                qytab.style.display='none';
                sctab = docment.getElementById('sctab');
                sctab.style.display='block';
                pic.style.background = "url(pic/bgsq.jpg) -33px 0px no-repeat";
            }
            
        }
      

  4.   

    onMouseOver="switchTo(rm)
    &
    onMouseOver="switchTo(jl)
    拿掉 
    要么添加两个div
    <div id="rm"></div>
    <div id="jl"></div>
