通用的页码导航代码（使用include）

编写通用代码实现页面底部分页导航，效果如下

 

1. 在需要引入分页的地方加入下面代码，变量含义参见第2部分代码解释

<jsp:include page="/resources/include/pager.jsp">
<span style="white-space:pre">	</span><jsp:param value="admin_role" name="url" />
	<jsp:param value="10" name="currentpage"/>
<span style="white-space:pre">	</span></span><jsp:param value="10" name="totalpage"/>
</jsp:include>

2. 编制包含文件

<%@ page language="java" import="java.util.*" pageEncoding="UTF-8"%> 
<% 
    //页码跳转的链接地址 
    String url = request.getParameter("url"); 
    //当前页码 
    Integer current_page = Integer.parseInt(request 
            .getParameter("currentpage")); 
    //总体页码数 
    Integer total_page = Integer.parseInt(request 
            .getParameter("totalpage")); 
    int i; 
%> 
<div class="pagination"> 
    <ul> 
        <!--判斷是否顯示“上一頁”  --> 
        <%if (current_page != 1) {%> 
            <li><a    href="<%=url + "?pageno=" + (current_page - 1) %>">上一页</a></li> 
        <%}%> 
        <% 
            for (i = 1; i < total_page + 1; i++) { 
                if (i == current_page) { 
        %> 
                    <li class="active"><a href="<%=url + "?pageno=" + i%>"><%=i%></a></li> 
        <%            } else {%> 
                    <li><a href="<%=url + "?pageno=" + i%>"><%=i%></a></li> 
        <%        } 
            }%> 
        <!--判斷是否顯示“下一頁”  --> 
        <%if (current_page != total_page) {%> 
            <li><a href="<%=url + "?pageno=" + (current_page + 1)%>">下一页</a></li> 
        <%}        %> 
    </ul> 
</div>
