flex实现股票行情走势图示例代码

 
第一步：
jsp：1

复制代码 代码如下:

<%@page import="java.util.Random,java.util.GregorianCalendar"%>


<%
GregorianCalendar calendar = new GregorianCalendar();
int year = calendar.get(calendar.YEAR);
int month = calendar.get(calendar.MONTH) + 1;
int today = calendar.get(calendar.DAY_OF_MONTH);
String strday=year+","+month+","+today+",";
int sb = 400;
String[] dates = new String[] {strday+"14,60"};

String crutime=request.getParameter("time");
///crutime=crutime.replace(":",",");
if(crutime!=null){
crutime=crutime.replace(":",",");
dates = new String[] {strday+crutime};

}
for (int i = 0; i < dates.length; i++) {
Random random = new Random();
int r = random.nextInt(1000);
%>

<%
if (i < 10) {
%><%=r%>
<%
}
%>
<%=dates[i]%> <%=sb%>
<%
}
%>

jsp：2

复制代码 代码如下:

<%@ page language="java" import="java.util.*" pageEncoding="gb2312"%>
<%
String path = request.getScheme()+"://"+request.getServerName()+":"+request.getServerPort()+request.getContextPath();
%>

第二步flex代码：
