lz遇到的是这个问题，可以参考一下这篇文章http://hi.baidu.com/%B0%D9%B6%C8hihi/blog/item/f8da8a516ce47a1a377abea6.html就是加form之后传的day变成了一个字符串，而不是对象了如果要加form可以这么改 function getValue(obj,value)
      {
      eval("document.forms[0]."+obj).value=parseInt(myC_Top.cells[2].innerText)+"-"+parseInt(myC_Top.cells[3].innerText)+"-"+value;
      }
也可以写成eval("document.User."+obj)
