这篇文章主要为大家详细介绍了Java实现分页的前台页面和后台代码，具有一定的参考价值，感兴趣的小伙伴们可以参考一下
本文实例为大家分享了Java分页展示的具体代码，供大家参考，具体内容如下
先上图吧，大致如图，也就提供个思路（ps：使用了SSH框架）
前台JSP页面
<%@ page language="java" contentType="text/html; charset=utf-8"
pageEncoding="utf-8"%>
<%@taglib prefix="s" uri="/struts-tags"%>
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN" "http://www.w3.org/TR/html4/loose.dtd">

<script type="text/javascript">
//1分页下，动态添加disable给分页按钮
/*
$(function(){
var myPageId="//m.sbmmt.com/m/faq/#"+$("#hidCurrentPage").val();
var myPageAId="//m.sbmmt.com/m/faq/#"+$("#hidCurrentPage").val()+" a";
$(myPageAId).addClass('main-bgcolor');
$(myPageAId).attr('href','javascript:void(0)')
$(myPageId).addClass('disabled');
$(myPageId).addClass('disabledControl');
})
*/
//
$(function(){
})
//根据页数查询数据列表
function queryRequirListByPage(i) {
var pageNo=i;
var sortValue=$('#hidSortValue').val();
$.ajax({
