利用JSP代码段动态生成表格，表格数据来自内存中的数组或集合类容器（List、Map、Set）
①编写实体类bean/Student.java
package bean;
public class Student {
private String no;
private String name;
private String tel;
public Student() {};
public Student(String no,String name,String tel){
this.no = no;
this.name = name;
this.tel = tel;
}
public String getNo() {
return no;
}
public void setNo(String no) {
this.no = no;
}
public String getName() {
return name;
}
public void setName(String name) {
this.name = name;
}
public String getTel() {
return tel;
}
public void setTel(String tel) {
this.tel = tel;
}
}
②从数组和List容器中取出数据放入表格中
table.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ page import="bean.Student"%>
<html>
<head>
<title>table</title>
</head>
<body>
<%
//数组中预先准备好数据
Student[] stu = {new Student("001","pjt","15618919819"),
new Student("002","cxl","17722533733"),
new Student("003","fyx","14515722279") };
//List中预先准备好数据
List<Student> lstu = new ArrayList<Student>();
lstu.add(new Student("004","gg","14227189198"));
lstu.add(new Student("005","tt","18618988966"));
lstu.add(new Student("006","ddf","14728722874"));
%>
<%-- 从数组中取出数据放入表格中 --%>
<table border="1" bgcolor="#aa8899">
<tr><td>学号</td><td>姓名</td><td>联系电话</td></tr>
<%
for(int i=0; i<stu.length;++i) {
%>
<tr>
<td><%=stu[i].getNo() %></td>
<td><%=stu[i].getName() %></td>
<td><%=stu[i].getTel() %></td>
</tr>
<% } %>
</table>
<%-- 从List中取出数据放入表格中(学号带超链接) --%>
<table border="1" bgcolor="#aaff77">
<tr><td>学号</td><td>姓名</td><td>联系电话</td></tr>
<%
for(int i=0;i<lstu.size();++i) {
%>
<tr>
<td><a href=detail.jsp?no=<%=((Student)lstu.get(i)).getNo()%>>
<%=((Student)lstu.get(i)).getNo()%></a>
</td>
<td><%=((Student)lstu.get(i)).getName()%></td>
<td><%=((Student)lstu.get(i)).getTel()%></td>
</tr>
<% } %>
</table>
</body>
</html>
③超链接跳转页面的处理
detail.jsp
<%@ page language="java" import="java.util.*" pageEncoding="utf-8"%>
<html>
<head>
<title>detail.jsp</title>
</head>
<body>
<%
String no = request.getParameter("no");
%>
学号为<font size=4 color="red"><%=no%></font>同学的详细信息如下<br>
</body>
</html>
效果
点击学号"004"后的效果
