php+ajax实现无刷新分页

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：

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)

1、分页类具体使用

<?php

class Pagination {

  private $total; //数据表中总记录数
  private $listRows; //每页显示行数
  private $limit; //mysql 数据库的limit
  private $uri; //分页信息前面的uri地址
  private $pageNum; //页数
  private $config = array('header' => "个记录", "prev" => "【上一页】", "next" => "【下一页】", "first" => "【首 页】", "last" => "【尾 页】");
  private $listNum = 8;

  /*
   * $total 当前信息总条数
   * $listRows 每页显示的条数
   * $pa 下面的page
    http://网址/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;//不传入page，则默认显示首页
    $this->pageNum = ceil($this->total / $this->listRows);
    $this->limit = $this->setLimit();
  }

  //设置每页显示的条数
  private function setLimit() {
    return "Limit " . ($this->page - 1) * $this->listRows . ", {$this->listRows}";
  }

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

    $parse = parse_url($url);



    if (isset($parse["query"])) {
      parse_str($parse['query'], $params);
      unset($params["page"]);
      $url = $parse['path'] . '?' . http_build_query($params);
    }

    return $url;
  }

  //魔术方法，
  public function __get($args) {
    if ($args == "limit")
      return $this->limit;
    else
      return null;
  }

  //页面开始的条数
  private function start() {
    if ($this->total == 0)
      return 0;
    else
      return ($this->page - 1) * $this->listRows + 1;
  }

  //页面结束的条数
  private function end() {
    return min($this->page * $this->listRows, $this->total);
  }

  /*设置首页*/
  private function first() {
    $html = "";
    if ($this->page == 1)
      $html.=''.$this->config["first"].'';
    else
      $html.="{$this->config["first"]}";
      //$html.="{$this->config["first"]}";

    return $html;
  }

  /*设置上一页*/
  private function prev() {
    $html = "";
    if ($this->page == 1)
      $html.=''.$this->config["prev"].'';
    else
      $html.="{$this->config["prev"]}";
      //$html.="{$this->config["prev"]}";

    return $html;
  }

  //页码列表【首页】【2】【3】…………【尾页】
  private function pageList() {
    $linkPage = "";

    $inum = floor($this->listNum / 2);

    for ($i = $inum; $i >= 1; $i--) {
      $page = $this->page - $i;

      if ($page < 1)
        continue;

      $linkPage.="{$page}";
    }

    $linkPage.="{$this->page}";


    for ($i = 1; $i <= $inum; $i++) {
      $page = $this->page + $i;
      if ($page <= $this->pageNum)
        $linkPage.="{$page}";
      else
        break;
    }

    return $linkPage;
  }

  /*设置下一页*/ 
  private function next() {
    $html = "";
    if ($this->page == $this->pageNum)
      $html.=''.$this->config["next"].'';
    else
      $html.="{$this->config["next"]}";
      //$html.="{$this->config["next"]}";

    return $html;
  }

  /*设置尾页*/
  private function last() {
    $html = "";
    if ($this->page == $this->pageNum)
      $html.=''.$this->config["last"].'';
    else
      $html.="{$this->config["last"]}";
      //$html.="{$this->config["last"]}";

    return $html;
  }

  /*设置页面跳转*/
  private function goPage() {

    return 
    '
    ';
  }

  //页面列表配置选项
  function fpage($display = array(0, 1, 2, 3, 4, 5, 6, 7, 8)) {
    $html[0] = "共有{$this->total}{$this->config["header"]}";
    $html[1] = "每页显示" . ($this->end() - $this->start() + 1) . "条，本页{$this->start()}-{$this->end()}条";
    $html[2] = "{$this->page}/{$this->pageNum}页";

    $html[3] = $this->first();
    $html[4] = $this->prev();
    $html[5] = $this->pageList();
    $html[6] = $this->next();
    $html[7] = $this->last();
    $html[8] = $this->goPage();
    $fpage = '';
    foreach ($display as $index) {
      $fpage.=$html[$index];
    }

    return $fpage;
  }

}

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','root','111111');
mysql_select_db('shop', $link);
mysql_query("set names utf8");
$css = <<
  table {border:1px solid black; width:700px; margin:auto; border-collapse:collapse;}
  td {border:1px solid black; }

eof;
echo $css;

echo "


";

//1 引入分页类
include "./Pagination.php";

//2. 获得信息总条数
$sql = "select * from sw_goods";
$qry = mysql_query($sql);
$total = mysql_num_rows($qry);
$per  = 7;

//3. 实例化分页类对象
$page_obj = new Pagination($total,$per);

//4. 拼装sql语句，获得每页信息
//利用page_obj实现limit的灵活设置
//$page_obj -> limit;
$sqla = "select * from sw_goods ".$page_obj->limit;
$qrya = mysql_query($sqla);

//5. 获得页面列表
$pagelist = $page_obj -> fpage(array(3,4,5,6,7,8));

$i=1;
while($rsta = mysql_fetch_assoc($qrya)){
  echo "";
  echo "";
  echo "";
  echo "";
  echo "";
  echo "";
  echo "";
}
echo "";
echo "

  
序号
名称
数量
价格
时间
".$i++."
".$rsta['goods_name']."
".$rsta['goods_number']."
".$rsta['goods_price']."
".date("Y-m-d H:i:s",$rsta['goods_create_time'])."
".$pagelist."
";
