似乎很奇怪但仍然:
有什么方法可以让jsp页面的选择部分得到刷新?假设:
<% response.setIntHeader("Refresh",1); // refresh at an interval of 1 second %>
<!-- Html5 snippet that plays a sound that lasts more than a second !-->
<% jsp code %>
现在,我希望当页面刷新时,音频片段从它离开的位置开始。那可能吗 ?剪辑的大小 2.4 MB ?

使用Jquery刷新JSP中的perticular div元素
<script type="text/javascript" src="http://ajax.googleapis.com/ajax/
libs/jquery/1.3.0/jquery.min.js"></script>
<script type="text/javascript">
var auto_refresh = setInterval(
function ()
{
$('#load_tweets').load('record_count.php').fadeIn("slow");
}, 10000); // refresh every 10000 milliseconds
</script>
<body>
<div id="load_tweets"> </div>
</body>
<强> EDIT1 强>
reload-window.jsp //将此文件放在WEB-INF旁边
<%@page import="java.util.Calendar"%>
<%@page import="java.util.GregorianCalendar"%>
<%@page contentType="text/html" pageEncoding="UTF-8"%>
<%! GregorianCalendar newYear = new GregorianCalendar(2013, 0, 1);
/*
* 0 : January
* 1 : 1st January
* 2013 : year
*/%>
<div>
Time :
<%= (newYear.getTimeInMillis() - new GregorianCalendar().getTimeInMillis()) / 1000%>
</div>

这里的问题
$('#load_tweets').load('reload-window.jsp').fadeIn("slow");
}, 5000); // refresh every 5000 milliseconds
加载函数我们需要传递需要刷新的JSP
确保你的js位于正确的位置。
