我创建了个JSP页面.加了JAVA代码.为什么JSP不能自己调用啊?
代码如下:
<%@ page contentType="text/html; charset=gb2312" %>
<html>
<%! int vote[] = new int[3];%>
<%
String cost = request.getParameter("cost");
synchronized ( vote )
{
if ( cost!=null )
{
if( cost.compareTo("0")==0 )
vote[0]++;
if( cost.compareTo("1")==0 )
vote[1]++;
if( cost.compareTo("2")==0 )
vote[2]++;
}
}
%>
投票结果:<br>
候选人A:<%=vote[0]%><br>候选人B:<%=vote[1]%><br>候选人C:<%=vote[2]%><br>
<body>
<Form METHOD = "GET" ACTION = "11.jsp">
<p>投票</p>
<input type="radio" value="0" checked name="cost">候选人A<br>
<input type="radio" name="cost" value="1">候选人B<br>
<input type="radio" name="cost" value="2">候选人C<br>
<input type="submit" value="投票" name="B1">
</form>
</body>
</html>
另一张页面:
11.jsp:
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<%@ page import = "java.util.Calendar"%>
<html>
<head>
<title>跳转页面</title>
</head>
<body>
<%if( Calendar.getInstance().get( Calendar.AM_PM )==Calendar.AM ){ %>
Good Moring
<% } else { %>
Good Afternoon
<% } %>
</body>
</html>
跳转过去可以显示,但是就是不能进行投票啊.大哥们教教小弟啊..
