[求助]省市联动存储时该如何提取数据？
我想通过存储过程来进行会员注册，可是在省市联动环节上，老是读不到数据，请各位大虾帮忙看看！！谢谢！！
aspx文件中的代码：
<SCRIPT LANGUAGE="JavaScript">

return true;
}
function change(v)
{
var str="0";
for(i=0;i<v;i++)

str+=("_"+(document.getElementById(s[i]).selectedIndex-1));
};
var ss=document.getElementById(s[v]);

cs文件中。。。。
SqlParameter par7=new SqlParameter("@zy_sheng",SqlDbType.VarChar,20);
com2.Parameters.Add(par7);
par7.Direction=ParameterDirection.Input;
par7.Value=s1.SelectedItem.Value.ToString();
SqlParameter par8=new SqlParameter("@zy_city",SqlDbType.VarChar,20);
com2.Parameters.Add(par8);
par8.Direction=ParameterDirection.Input;
par8.Value=s2.SelectedItem.Value.ToString();
请问这两句红色的该如何写？
