1.首先，写一个带有单选按钮组件的前台页
1 <%@ page language="java" contentType="text/html; charset=UTF-8"
2 pageEncoding="UTF-8"%>
3 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
4 <html>
5 <head>
6 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
7 <title>Insert title here</title>
8 </head>
9 <body>
10 <form action="request1.jsp" method="post">
11 男:<input type="radio" name="gender" value="男" />
12
13 女:<input type="radio" name="gender" value="女" />
14 <br>
15 <input type="submit" />
16 </form>
17 </body>
18 </html>
2.然后，在处理页获取单选按钮组件的值
1 <%@page import="java.util.Enumeration"%>
2 <%@ page language="java" contentType="text/html; charset=UTF-8"
3 pageEncoding="UTF-8"%>
4 <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">
5 <html>
6 <head>
7 <meta http-equiv="Content-Type" content="text/html; charset=UTF-8">
8 <title>Insert title here</title>
9 </head>
10 <body>
11 <%
12
13 request.setCharacterEncoding("utf-8");
14
15 String gender = request.getParameter("gender");
16
17 out.println(gender);
18
19 %>
20 </body>
21 </html>
