  function setcheck(id,ddd)//id表示控件ID号,ddd表示值
  {
    var   radiolist   =  id;  
   
      for(var   i=0;i<document.getElementById(radiolist).rows.length;i++)  
      {  
          for(var   x=0;x<document.getElementById(radiolist).rows[i].cells.length;x++)  
          {  
              if(document.getElementById(radiolist).rows[i].cells[x].firstChild!="undefine")  
              {    
                  if(document.getElementById(radiolist).rows[i].cells[x].firstChild.value==ddd)  
                  {  
                    document.getElementById(radiolist).rows[i].cells[x].firstChild.checked=true;  
                  }
                                             
              }  
          }  
      }
