flex实现股票行情走势图示例代码
作者：
股票行情走势图在flex中也可以实现了，具体步骤及代码如下，感兴趣的朋友可以参考下，或许有所帮助
第一步：
jsp：1
复制代码 代码如下:
<%@page import="java.util.Random,java.util.GregorianCalendar"%>
<?xml version="1.0" encoding="utf-8"?>
<items>
<%
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);
%>
<item> <value>
<%
if (i < 10) {
%><%=r%>
<%
}
%>
</value> <date><%=dates[i]%></date> <sb><%=sb%></sb> </item>
<%
}
%>
</items>
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();
%>

<div id="flashcontent" width="600" height="400" align="center" ></div>
<script type="text/javascript">
var so = new SWFObject("<%=path%>/testfrist.swf", "Main", "600", "400","9.0", "#ffffff", "high");
so.addVariable("myAmfurl","<%=path%>/nxsy.jsp");
so.addVariable("myAmtitle","牛熊双赢");
so.write("flashcontent");

</div>
