这里运用smarty模板,更简单

本文主要的技术:ajax,php,smarty,另外自己封装了一个很简单的类

类:

  (function(){
function $(id) {
return document.getelementbyid(id);
}
$.init=function() {
try{return new xmlhttprequest();}catch(e){};
try{return new activexobject('microsoft.xmlhttp');}catch(e){}
alert('请更换浏览器');
}
$.get=function (url,data,callback,type) {
var xhr = this.init();
url += '?' +new date().gettime();
if(data!=null){
url += '&'+data;
}
xhr.open('get',url);
xhr.onreadystatechange = function () {
if(xhr.readystate == 4 && xhr.status == 200){
if(type==null){
callback(xhr.responsetext);
}
if(type == 'text'){
callback(xhr.responsetext);
}
if(type == 'xml'){
callback(xhr.responsexml);
}
if(type == 'json'){
callback(eval("("+xhr.responsetext+")"));
}
}
}
xhr.send(null);
}

$.post = function (url,data,callback,type) {
var xhr = this.init();
xhr.open('post',url);
xhr.setrequestheader('content-type','application/x-www-form-urlencoded');
xhr.onreadystatechange = function () {
if(xhr.readystate == 4 && xhr.status == 200){
if(type==null){
callback(xhr.responsetext);
}
if(type == 'text'){
callback(xhr.responsetext);
}
if(type == 'xml'){
callback(xhr.responsexml);
}
if(type == 'json'){
callback(eval("("+xhr.responsetext+")"));
}
}
}; 
xhr.send(data);
}

 类很简单,不介绍了

html:

  window.onload=function () {
init(2);
}
function del(id,p){
$.get('del.php','id='+id,function(msg){
if(msg==1){
init(p);
}
})
}
function init(p) {
$.get('page.php','page='+p,function(msg){
$('result').innerhtml=msg;
});
}

php:

<?php
header('content-type:text/html;charset=utf-8');
mysql_connect('localhost','root','root');
mysql_select_db('db2');
mysql_query('set names utf8');
$re=mysql_query('select count(*) as num from catgory');
$hang=mysql_fetch_assoc($re);
$row1=$hang['num'];
$page=isset($_get['page'])? $_get['page']:1;
$pagesize=2;
$total=ceil($row1/$pagesize);
$prev=$page-1;
$next=$page+1;
if($prev<1){$prev=1;}
if($next>$total){$next=$total;}
$offset = ($page-1)*$pagesize;
$result=mysql_query("select * from catgory limit ".$offset.','.$pagesize);
$ct=mysql_num_rows($result);
$data=array();
for($i=0;$i<$ct;$i++){
$r=mysql_fetch_assoc($result);
$data[]=$r;
}
include('libs/smarty.class.php');
$smarty=new smarty();
$smarty->assign('data',$data);
$smarty->assign('page',$page);
$smarty->assign('pagesize',$pagesize);
$smarty->assign('total',$total);
$smarty->assign('prev',$prev);
$smarty->assign('next',$next);
$smarty->assign('row1',$row1);
$str=$smarty->fetch('page.html');
echo $str;

smarty:

    <table border="1" rules="all" width="600">
<tr>
<td>编号</td>
<td>品牌</td>
<td>pid</td>
<td>删除</td>
</tr>
{foreach from=$data item='value'}
<tr>
<td>{$value['id']}</td>
<td>{$value['name']}</td>
<td>{$value['pid']}</td>
<td><a href="#", onclick="del({$value['id']},{$page})">删除</td>
</tr>
{/foreach}
<tr>
<td colspan="3">
共{$total}页
第{$page}页
<a href="#", onclick="init({$prev})">上一页</a>
<a href="#", onclick="init({$next})">下一页</a>
<a href="#", onclick="init(1)">第一页</a>
<a href="#", onclick="init({$total})">最末页</a>
共{$row1}条数据
每页{$pagesize}条数据
</td>
</tr>
</table>

要引入smary模板

以上所述是小编给大家介绍的ajax+smarty技术实现无刷新分页,希望对大家有所帮助!
