  1.   

    function Jump(j){
    for(i=0; i <2; i++) {  
      document.getElementById("bgs" + i).className="bgimg" + i;  
      if( i==j )   
      document.getElementById( "bgs" + i).style.display="block";  
      else   
      document.getElementById( "bgs" + i).style.display="none";  
      }  
    }bgi换为bgs,在js模块也看到这个贴
