php+ajax实现无刷新分页，phpajax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

 "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 ($page uri}&page={$page}\")'>{$page} ";
    }

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


    for ($i = 1; $i page + $i;
      if ($page 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

  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'])."
