一款基于原生态的php +js +ajax 的分页程序实例,我们详细的从数据库创建到js,php,html页面的创建来告诉你如何实现ajax分页调用数据的方法。
代码如下 | 复制代码 |
CREATE TABLE `tb_user` (
|
ajaxpage.js ~ 1KB
代码如下 | 复制代码 |
var http_request=false; function send_request(url){//初始化,指定处理函数,发送请求的函数 http_request=false; //开始初始化XMLHttpRequest对象 if(window.XMLHttpRequest){//Mozilla浏览器 http_request=new XMLHttpRequest(); if(http_request.overrideMimeType){//设置MIME类别 http_request.overrideMimeType("text/xml"); } } else if(window.ActiveXObject){//IE浏览器 try{ http_request=new ActiveXObject("Msxml2.XMLHttp"); }catch(e){ try{ http_request=new ActiveXobject("Microsoft.XMLHttp"); }catch(e){} } } if(!http_request){//异常,创建对象实例失败 window.alert("创建XMLHttp对象失败!"); return false; } http_request.onreadystatechange=processrequest; //确定发送请求方式,URL,及是否同步执行下段代码 http_request.open("GET",url,true); http_request.send(null); } //处理返回信息的函数 function processrequest(){ if(http_request.readyState==4){//判断对象状态 if(http_request.status==200){//信息已成功返回,开始处理信息 document.getElementById(reobj).innerHTML=http_request.responseText; } else{//页面不正常 alert("您所请求的页面不正常!"); } } } function dopage(obj,url){ document.getElementById(obj).innerHTML="正在读取数据..."; reobj = obj; send_request(url); } |
php调用代码
代码如下 | 复制代码 | ||||
$terry=mysql_connect("localhost","root","")or die("连接数据库失败:".mysql_error()); mysql_select_db("ajaxtest",$terry); mysql_query("set NAMES 'utf8'"); $result=mysql_query("select * from tb_user"); $total=mysql_num_rows($result) or die(mysql_error()); $page=isset($_GET['page'])?intval($_GET['page']):1; $pagenum=ceil($total/$page_size); if($page>$pagenum){
echo " $pagenav ";?> |
大家使用时只在一段段代码按我个面的保存成单个文件就可以实现了哦。
