  for(var i=0;i<li.length;i++){
              li[i].index = i;
              li[i].onmouseover = function(){
                      for(var n=0;n<box.length;n++){
                          if(this.index==n){
                             
                             box[this.index].className = 'box show';  
                          }else{
                              box[n].className = 'box hide';   
                       
                          }
                      }
                   
              }
             
              
          }

  是这样吗？
