out.print("</TR>");
}
out.print("</table>");
rs.close();
stmt.close();
con.close();

我这里是用打印的方式输出表的，我想问一下怎么在按下删除按钮或修改按钮时能把 rs.getString(1) 的值传递到shanchu.jsp或xiugai.jsp里

str 是你自定义的一个名称

在另一个jsp页面中用 String str = request.getParameter("str"); 获取

<form action=xiugai.jsp><input type=submit value= 修改 /></form> <form action=shanchu.jsp><input type=submit value= 删除 /></form> 修改成 <a href='xiugai.jsp?id= rs.getString(1) > 修改</> <a href='shanchu.jsp?id= rs.getString(1) > 删除</> 然后分别在xiugai.jsp和shanchu.jsp页面接收id传过来的值
