一、先建立用户输入的数据
usingGetparameter.html
1 <!DOCTYPE html> 2 <html> 3 <head> 4 <meta charset="UTF-8"> 5 <title>Users to input date</title> 6 </head> 7 <body> 8 <form action="usingGetParameter.jsp" method="post"></form> 9 <table border="2" bgcolor="#F8DBE5"> 10 <tr><td bgcolor="#F9BADA">姓名：</td> 11 <td><input type="text" name="name"></td></tr> 12 <tr><td bgcolor="#F9BADA">电话：</td> 13 <td><input type="text" name="tel"></td></tr> 14 <tr><td bgcolor="#F9BADA">电子邮箱：</td> 15 <td><input type="text" name="email"></td></tr> 16 <tr><td colspan="2" align="center"> 17 <input type="submit" value="确定"> 18 <input type="reset" value="重置"> 19 </td></tr> 20 </table> 21 </body> 22 </html>
二、服务器获取信息
usingGetParemeter.jsp
1 <%@ page language="java" contentType="text/html; charset=ISO-8859-1"
2 pageEncoding="ISO-8859-1"%>
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=ISO-8859-1">
7 <title>Jsp page show dates</title>
8 </head>
9 <body>
10 <%
11 String name = request.getParameter("name");
12 String email = request.getParameter("email");
13 String tel = request.getParameter("tel");
14 %>
15 Hello~~~<%=name %>Here....<br> <br>
16 What you input are as follows:
17 <p>
18 姓 名：<%=name %><br><br>
19 电子邮箱：<%=email %><br><br>
20 电 话：<%=tel %>
21 </body>
22 </html>
三、运行结果：
上面是比较简单的介绍JavaBean处理表单的例子。。
四、JSP+JavaBean
一、用户输入信息：
showInf.jsp
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>Show users‘ information</title>
8 </head>
9 <body>
10 <jsp:useBean id="user" scope="session" class="jsp.test.show"></jsp:useBean>
11 <jsp:setProperty property="*" name="user"/>
12 <%if(request.getParameter("name")==null){ %>
13
14 <form action="" name="Example"method="post">
15 <p>姓名： <input type="text" name="name" size="17" maxlength="17"></p>
16 <p>密码： <input type="password" name="password" size="17" maxlength="17"></p>
17 <p>性别：<input type="radio" name="sex" value="F" checked>女
18 <input type="radio" name="sex" value="M">男
19 </p>
20 <p>年龄：
21 <select name="age">
22 <option value="10">10~20</option>
23 <option value="20" selected>21~30</option>
24 <option value="30">31~40</option>
25 <option value="40">41~70</option>
26 </select>
27 </p>
28
29 <p>特长：
30 <input type="checkbox" name="specialty" value="Music">
31 音乐
32 <input type="checkbox" name="specialty" value="Write">
33 写作
34 <input type="checkbox" name="specialty" value="SoftWare">
35 软件
36 <input type="checkbox" name="specialty" value="Photo">
37 摄影
38 </p>
39 <p>
40 <input type="submit" value="传送">
41 <input type="submit" value="清除">
42 </p>
43 </form>
44 <%}else{ %>
45 姓名：<%=user.getName() %><br><br>
46 密码：<%=user.getPassword() %><br><br>
47 性别：<%=user.getSex() %><br><br>
48 年龄：<%=user.getAge() %><br><br>
49 特长：<%=user.getHobby() %><br><br>
50 <%} %>
51
52 </body>
53 </html>
二、服务器接收信息：
show.java
1 package jsp.test;
2
3 public class show {
4
5 private String name;
6 private String password;
7 private String sex;
8 private String age;
9 private String hobby;
10 private String[] specialty;
11
12
13 public String getHobby() {
14 return hobby;
15 }
16 public void setHobby(String hobby) {
17 this.hobby = hobby;
18 }
19 public void setSpecialty(String[] specialty) {
20 hobby="";
21 for(int i = 0; i<specialty.length; i++)
22 {
23 if(specialty[i].equals("Music"))
24 {
25 hobby += "音乐";
26 }
27 if(specialty[i].equals("Write"))
28 {
29 hobby += "写作";
30 }
31 if(specialty[i].equals("SoftWare"))
32 {
33 hobby += "软件";
34 }
35 if(specialty[i].equals("Photo"))
36 {
37 hobby += "摄影";
38 }
39 }
40 }
41 public String getName() {
42 return name;
43 }
44 public void setName(String name) {
45 this.name = name;
46 }
47 public String getPassword() {
48 return password;
49 }
50 public void setPassword(String password) {
51 this.password = password;
52 }
53 public String getSex() {
54 return sex;
55 }
56 public void setSex(String sex) {
57 if(sex.equals("Male")){
58 this.sex="男";
59 }
60 else{
61 this.sex="女";
62 }
63 }
64 public String getAge() {
65 return age;
66 }
67 public void setAge(String age) {
68
69 int age1=Integer.parseInt(age);
70 switch(age1)
71 {
72 case 10:
73 this.age="10~20";
74 break;
75 case 20:
76 this.age="21~30";
77 break;
78 case 30:
79 this.age="31~40";
80 break;
81 case 40:
82 this.age="41~70";
83 break;
84 default:
85 this.age="error";
86 break;
87 }
88 }
89 public String[] getSpecialty() {
90 return specialty;
91 }
92
93
94 }
三、运行结果：
后面的显示中姓名出现乱码。。。。
暂时就到这儿了。。
