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
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;
}
}
