我要实现的功能是这样的，test.jsp是一个饼状图，是别人做好的完整的页面，我想在我的页面index.jsp中嵌入test.jsp
当然就用到了iframe了，但是这样就有个问题，子页面中的饼状图是自动刷新的，父页面无法实时的把数据传给子页面，
我的办法是:在子页面中调用父页面中js方法，获取返回值。
具体代码如下：
index.jsp:
<%@ page contentType="text/html; charset=gb2312" language="java" import="java.sql.*" errorPage="" %>
<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="http://www.w3.org/1999/xhtml">
<head>
<meta http-equiv="Content-Type" content="text/html; charset=gb2312" />
<title>无标题文档</title>
</head>
<script language="javascript">
//这是子页面将要调用的方法
function f(){
return "yyy,90,kkk,100,uu,80";
}
</script>
<body>
<table width="200" border="1">
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
<tr>
<td><iframe scrolling="yes" src="test.jsp" width="600" height="600"></iframe><!--这里是我要加入的页面-->
</td>
<td> </td>
<td> </td>
</tr>
<tr>
<td> </td>
<td> </td>
<td> </td>
</tr>
</table>
</body>
</html>
