php+ajax实现无刷新分页

php  /  管理员 发布于 8年前   208

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      $html.=" uri}&page=1\")'>{$this->config["first"]} ";      //$html.=" uri}&page=1'>{$this->config["first"]} ";    return $html;  }  /*设置上一页*/  private function prev() {    $html = "";    if ($this->page == 1)      $html.=' '.$this->config["prev"].' ';    else      $html.=" uri}&page=" . ($this->page - 1) . "\")'>{$this->config["prev"]} ";      //$html.=" uri}&page=".($this->page-1)."'>{$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;      $linkPage.=" uri}&page={$page}\")'>{$page} ";    }    $linkPage.=" {$this->page} ";    for ($i = 1; $i <= $inum; $i++) {      $page = $this->page + $i;      if ($page <= $this->pageNum)        $linkPage.=" uri}&page={$page}\")'>{$page} ";      else        break;    }    return $linkPage;  }  /*设置下一页*/   private function next() {    $html = "";    if ($this->page == $this->pageNum)      $html.=' '.$this->config["next"].' ';    else      $html.=" uri}&page=" . ($this->page + 1) . "\")'>{$this->config["next"]} ";      //$html.=" uri}&page=".($this->page + 1)."'>{$this->config["next"]} ";    return $html;  }  /*设置尾页*/  private function last() {    $html = "";    if ($this->page == $this->pageNum)      $html.=' '.$this->config["last"].' ';    else      $html.=" uri}&page=" . ($this->pageNum) . "\")'>{$this->config["last"]} ";      //$html.=" uri}&page=.(this->pageNum).'>{$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;  }}
