php+ajax實現無刷新分頁,phpajax刷新分頁


本文實例講述了php+ajax實現無刷新分頁實現方法。分享給大家供大家參考。具體如下:

    limit  偏移量,長度;
    limit  0,7;   第一頁
    limit  7,7;   第二頁
    limit  14,7;  第三頁
每頁信息條數:7
信息總條數:select count(*) from table
信息總頁數:ceil向上取整(總條數/每頁條數)
1、分頁類具體使用

<?php

class Pagination {

  private $total; //數據表中總記錄數
  private $listRows; //每頁顯示行數
  private $limit; //mysql 數據庫的limit
  private $uri; //分頁信息前面的uri地址
  private $pageNum; //頁數
  private $config = array('header' => "個記錄", "prev" => "【上一頁】", "next" => "【下一頁】", "first" => "【首 頁】", "last" => "【尾 頁】");
  private $listNum = 8;

  /*
   * $total 當前信息總條數
   * $listRows 每頁顯示的條數
   * $pa 下面的page
    http://網址/index.php?page=5
   */

  public function __construct($total, $listRows = 10, $pa = "") {
    $this->total = $total;
    $this->listRows = $listRows;
    $this->uri = $this->getUri($pa);
    $this->page = !empty($_GET["page"]) ? $_GET["page"] : 1;//不傳入page,則默認顯示首頁
    $this->pageNum = ceil($this->total / $this->listRows);
    $this->limit = $this->setLimit();
  }

  //設置每頁顯示的條數
  private function setLimit() {
    return "Limit " . ($this->page - 1) * $this->listRows . ", {$this->listRows}";
  }

  //獲得URL地址
  private function getUri($pa) {
    $url = $_SERVER["REQUEST_URI"] . (strpos($_SERVER["REQUEST_URI"], '?') ? '' : "?") . $pa;

    $parse = parse_url($url);



    if (isset($parse["query"])) {

    }

2 數據顯示

<?php

//鏈接數據庫

//獲得具體信息

//分頁顯示
header("content-type:text/html;charset=utf-8");
$link = mysql_connect('localhost','root','111111');
mysql_select_db('shop', $link);
mysql_query("set names utf8");
$css = <<<eof
<style type="text/css">
  table {border:1px solid black; width:700px; margin:auto; border-collapse:collapse;}
  td {border:1px solid black; }
</style>
eof;
echo $css;

echo "
<table>
  <tr><td>序號</td><td>名稱</td><td>數量</td><td>價格</td><td>時間</td></tr>

";

//1 引入分頁類
include "./Pagination.php";

//2. 獲得信息總條數
$sql = "select * from sw_goods";
$qry = mysql_query($sql);
$total = mysql_num_rows($qry);
$per  = 7;

//3. 實例化分頁類對象
$page_obj = new Pagination($total,$per);

//4. 拼裝sql語句,獲得每頁信息
//利用page_obj實現limit的靈活設置
//$page_obj -> limit;
$sqla = "select * from sw_goods ".$page_obj->limit;
$qrya = mysql_query($sqla);

//5. 獲得頁面列表
$pagelist = $page_obj -> fpage(array(3,4,5,6,7,8));

$i=1;
while($rsta = mysql_fetch_assoc($qrya)){
  echo "<tr>";
  echo "<td>".$i++."</td>";
  echo "<td>".$rsta['goods_name']."</td>";
  echo "<td>".$rsta['goods_number']."</td>";
  echo "<td>".$rsta['goods_price']."</td>";
  echo "<td>".date("Y-m-d H:i:s",$rsta['goods_create_time'])."</td>";
  echo "</tr>";
}
echo "<tr><td colspan=5>".$pagelist."</td></tr>";
echo "</table>";

3 ajax無刷新分頁實現

open(‘get','http://網址/index.php?page=2')

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Strict//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-strict.dtd">
<html>
  <head>
    <title>新建網頁</title>
    <meta http-equiv="Content-Type" content="text/html; charset=utf-8" />
    <meta name="description" content="" />
    <meta name="keywords" content="" />

    <script type="text/javascript">
//獲得分頁信息ajax函數
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"); //獲得分頁信息
  //showPage("./data.php?page=2");
}
    </script>

    <style type="text/css">
    </style>
  </head>


  <body>
    <h2>ajax無刷新分頁效果</h2>
    <div id="result"></div>
  </body>
</html>
<script type="text/javascript">
  document.write(new Date()+"<br />");
  document.write(new Date()+"<br />");
  document.write(new Date()+"<br />");
  document.write(new Date()+"<br />");
</script>
