Answer 1

function fsCheck(num){
 return document.fs.nsns[num].checked;
}

Answer 2

只想把这句document.fs.nsns共用为一句，怎么改呢？

Answer 3

你的一一对应可以考虑使用关联来做
这样可以避免冗长而不好看的ifelse

Answer 4

你的那句修改为
ts([2,4,7,8,9,10])function ts(o)
{
  for(var i in o)
  {
     if(document.fs.nsns[o[i]].checked)
     {
        return true;
        break;
     }
  }
  return false;
}
