如图是index.jsp我简单的写了一个请求，就是到数据库中查询所有的用户的信息，然后返回到index.jsp页面上，但是在index.jsp页面上我无法接收到值。index.jsp<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<title>父页面</title>
</head><body>
<iframe src="user.jsp" style="margin-left: 500px;" name="main"
width="500px" height="200px"></iframe>
<iframe src="test.jsp"></iframe>
<s:debug/>
</body>
</html>
user.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<%@ taglib uri="/struts-tags" prefix="s"%>
<html>
<head>
<title>用户的页面---用来显示用户的信息</title>
</head><body>
这是用户的页面,在这里显示用户的信息。
<s:iterator value="users" var="user">
<s:property value="#user.userName" />
<s:property value="#user.passWord" />
</s:iterator>
<s:debug/>
</body>
</html>test.jsp
<%@ page language="java" import="java.util.*" pageEncoding="GBK"%>
<html>
<body>
这是一个用于测试的页面。
<form action="userAction_findUsers" method="post">
<input type="submit" value="提交" />

2.在子页面使用$.ready调用AJAX回去取数据吧，或者写在父页面隐藏域中，子页面通过JS的dom操作设值
