本文介绍如何在JSP中实现页面间的参数传递及分页功能，通过具体实例展示了如何使用`<jsp:param>`标签进行参数传递，并利用Struts标签库实现条件分页导航。
先看一个简单的应用,在a.jsp中写如下代码
<div>
<jsp:include page="name.jsp" >
<jsp:param name="name" value="徐越" />
</jsp:include>
</div>
这就将名为name，值为徐越的参数传送到name.jsp。
<wbr></wbr>
那么在name.jsp中接收参数
<wbr><br><wbr> <%<br><wbr><strong><span style="color:#ed1c24">String n=request.getParameter("name");<br></span></strong><wbr> if(n!= null && !"".equals(n.trim()))<br><wbr> out.println(n);<br><wbr> %><br></wbr></wbr></wbr></wbr></wbr></wbr>
<wbr> <div id="showName"><%=url></div></wbr>
<wbr></wbr>
<wbr></wbr>
<wbr></wbr>
我们来看一个分页的应用
<wbr></wbr>
pager.jsp
<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%>
<%
<wbr>String path = request.getContextPath();<br><wbr>String basePath = request.getScheme() + "://" + request.getServerName() + ":" + request.getServerPort() + path + "/";<br> %></wbr></wbr>
<%@tagliburi="/struts-tags" prefix="s"%>
<!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN">

其中pageNum还有data.totalpage等，就涉及到ssh分页的知识了，就不在这里赘述了。
stduent.jsp
......
<div>
<wbr><wbr><jsp:include page="../pager.jsp"><br><wbr><wbr><strong><jsp:param<wbr> name="url"/ value="stu/Stu_toquery" /><br></wbr></strong><wbr><wbr></jsp:include><br> </div></wbr></wbr></wbr></wbr></wbr></wbr>
......
<wbr></wbr>
这样就可以完成分页页面的嵌入了。
