在iframe里的页面编写js，实现在父窗口上创建动画效果展开和收缩的div（不变动iframe父窗口代码）

代码如下:

<%@ page contentType="text/html; charset=GBK" language="java"%>
<%@ page import="com.jstrd.mm.business.sysmgr.monitor.logic.MMStock2BudgetLogic" %>
<%
String query = request.getParameter("query");
MMStock2BudgetLogic bean = new MMStock2BudgetLogic();
String xmldata = bean.statStock2Budget();
%>
<html>
<head>
<meta http-equiv="Content-Type" content="text/html; charset=GBK">
<META HTTP-EQUIV="Pragma" CONTENT="no-cache">
<META HTTP-EQUIV="Cache-Control" CONTENT="no-cache">
