php+ajax实现无刷新分页，phpajax刷新分页

基督教网站源码,Ubuntu光盘系统安装,项目打包放在tomcat上,爬虫软件 csdn,php代码注入漏洞,seo推广代运营怎么做外推lzw

本文实例讲述了php+ajax实现无刷新分页实现方法。分享给大家供大家参考。具体如下：

android源码百度云盘,vscode32位中文下载,ubuntu终端换页,tomcat7 自动配置,爬虫稳定吗,php权威指南网盘,铁门关seo网络营销广告lzw

limit 偏移量，长度;

limit 0,7; 第一页

limit 7,7; 第二页

limit 14,7; 第三页

每页信息条数：7

信息总条数：select count(*) from table

信息总页数：ceil向上取整(总条数/每页条数)

2 数据显示

<?php//链接数据库//获得具体信息//分页显示header("content-type:text/html;charset=utf-8");$link = mysql_connect(localhost, oot,111111);mysql_select_db(shop, $link);mysql_query("set names utf8");$css = <<<eof table {border:1px solid black; width:700px; margin:auto; border-collapse:collapse;} td {border:1px solid black; }eof;echo $css;echo "

";

3 ajax无刷新分页实现

open(‘get’,’http://网址/index.php?page=2′)

//获得分页信息ajax函数function showPage(myurl){ var xhr = new XMLHttpRequest(); xhr.onreadystatechange = function(){ if(xhr.readyState==4){var rst = document.getElementById("result");rst.innerHTML = xhr.responseText; } } xhr.open("get",myurl); xhr.send(null);}window.onload = function(){ showPage("./data1.php"); //获得分页信息 //showPage("./data.php?page=2");}ajax无刷新分页效果

document.write(new Date()+"

"); document.write(new Date()+"

"); document.write(new Date()+"
