Summary of how PHP implements ajax paging
How does PHP implement ajax paging? In this article, the editor introduces the ajax paging function implemented by ajax combined with jquery using PHP.
1. First make the main page Ajax_pag.php
The code is as follows:
<!DOCTYPE html>
<html>
<head>
<meta charset="UTF-8">
<title>Ajax做分页</title>
<script src="bootstrap/js/jquery-1.11.2.min.js"></script>
<script src="Ajax_pag.js"></script>
<script src="bootstrap/js/bootstrap.min.js"></script>
<link href="bootstrap/css/bootstrap.min.css" rel="stylesheet" type="text/css"/>
</head>
<style>
.header{
margin-top: 20px;
}
</style>
<body>
<div style="margin-top: 20px; margin-top: 20px;">
关键字：
<input id="key" type="text" name="gjz"/>
<input type="button" value="查询" id="ck" />
</div>
<table class="table table-bordered header">
<thead>
<tr>
<th>地区代号</th>
<th>地区名称</th>
<th>父级代号</th>
</tr>
</thead>
<tbody id="list">
</tbody>
</table>
<div style="margin:0 auto; width:500px;">
<ul class="pagination" id="fenye">
</ul>
</div>
</body>
</html>2. Then make the paging query JS page Ajax_pag.js
The code is as follows:
//ajax分页开始
var ts = 10;//每页显示的条数
var page = 1;//当前页
$(document).ready(function(e) {
//页面加载数据
Load();
//加载分页列表
Loadlist();
$("#ck").click(function(){
//页面加载数据
Load();
//加载分页列表
Loadlist();
})
})
//加载数据的方法
function Load(){
var gjz = $("#key").val();
$.ajax({
async:false,
url:"pagechuli.php",
data:{page:page,ts:ts,gjz:gjz},//page是显示的页数；ts是显示的条数
type:"POST",
dataType:"JSON",
success: function(data){
var str ="";
for(var k in data)
{
str +="<tr><td>"+data[k][0]+"</td><td>"+data[k][1]+"</td><td>"+data[k][2]+"</td></tr>";
}
$("#list").html(str);//把拼接好的字符串放到要显示的thody里面
}
})
}
//加载分页列表
function Loadlist(){
var str ="";
//上一页
str+="<li><a id='prev'>«</a></li>";
//加载列表
for(var i=page-4;i<page+5;i++){
//限制条件
if(i>0 && i<=zys()){
//判断当前页
if(i==page){
str+= "<li class='active'><a>"+i+"</a></li>";
}else{
str+= "<li><a class='item'>"+i+"</a></li>";
}
}
}
//下一页
str+="<li><a id='next'>»</a></li>";
$("#fenye").html(str);
$("#prev").click(function(){
if(page>1){
page--;
}
//页面加载数据
Load();
//加载分页列表
Loadlist();
})
$(".item").click(function(){
var p = $(this).text();//取到的是字符串,转化为整数
page = parseInt(p);
//页面加载数据
Load();
//加载分页列表
Loadlist();
})
$("#next").click(function(){
if(page<zys()){
page++;
}
//页面加载数据
Load();
//加载分页列表
Loadlist();
})
}
//总页数
function zys(){
var zys = 0;
$.ajax({
async:false,
url:"zyschuli.php",
dataType:"TEXT",
success:function(data){
zys = Math.ceil(data/ts);
}
});
return zys;
}3. Finally, do the paging query processing page pagechuli.php
The code is as follows:
<?php
$gjz = $_POST["gjz"];
$page = $_POST["page"];//获取页数显示值
$ts = $_POST["ts"];//获取每页条数显示值
require_once "./DBDA.class.php";
$db = new DBDA();
$tj = " 1=1 ";
if(!empty($_POST["gjz"])){
$gjz = $_POST["gjz"];
$tj = " areaname like '%{$gjz}%' or areacode like '%{$gjz}%' or parentareacode like '%{$gjz}%' ";
}
$tg = ($page-1)*$ts;//每页显示$ts条数据，这里显示的就是当前页的$tg条数据。
$sql = "select * from chinastates where {$tj} limit {$tg},{$ts}";
echo $db->JsonQuery($sql,0)Small plug-in: The processing page of the total number of pages zyschuli.php
<?php require_once "./DBDA.class.php"; $db = new DBDA(); $sql = "select count(*) from chinastates"; echo $db->StrQuery($sql,0);
The effect is as shown below:
The effect of keyword query is as follows:
