我写了个购物车的JSP代码,如下:
<html>
<head>
<title>添加购物车</title>
</head>
<style type="text/css">
<body bgcolor="#FFFFFF">
<%@ page import="java.sql.*"%>
<jsp:useBean id="conn" scope="page" class="myshop.conn"/>
<%@ page import="buylist.buylist"%>
<%
String ISBN=request.getParameter("isbn");
String TITLE="";
String PRICE="";
String sql="select TITLE,PRICE from bookinfo where ISBN='"+ISBN+"'";
ResultSet rs=conn.executeQuery(sql);
if(rs.next())
{TITLE=rs.getString("TITLE");
PRICE=rs.getString("PRICE");
}
buylist mylist=new buylist();
mylist.TITLE=TITLE;
mylist.ISBN=ISBN;
mylist.number=1;
boolean listFlag=true;
Vector shop=(Vector)session.getValue("shop");
if(shop==null)
{shop=new Vector();
}
else
{
for(int i=0;i<shop.size();i++)
{buylist list=(buylist)shop.elementAt(i);
if(list.ISBN==mylist.ISBN)
{list.number++;
shop.setElementAt(list,i);
listFlag=false;
}
}
if(listFlag)shop.addElement(mylist);
session.putValue("shop".shop);
rs.close();
%>
<br><font size="4" color="#FF0033">您选购的书籍已经成功的添加到购物车中！</font></b><br>
<br>
<a href="JaavaScript:window.close()">关闭窗口</a>
<a href="list.jsp target="_blank" onclick="javaScript:window.close()">查看购物车
</a></div>
</body>
</html>
上面的mysho.conn javabean 没问题,可能问题出在那个buylist 类
package buylist;
public class buylist
{public String TITLE;
public int id;
public int number;
public String PRICE;
public String ISBN;
}
运行后显示如下:
