首页 / 网页编程 / PHP / 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



<?phpclass 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limitprivate $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 * $pa 下面的pagehttp://网址/index.php?page=5 */public function __construct($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"], "?") ?

"?" . http_build_query($params);}return $url;}//魔术方法,public function __get($args) {if ($args == "limit")return $this->limit;elsereturn null;}//页面开始的条数private function start() {if ($this->total == 0)return 0;elsereturn ($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.=" <a href="javascript:void(0)" onclick="showPage("{$this->uri}&page=1")">{$this->config["first"]}</a> ";//$html.=" <a href="{$this->uri}&page=1">{$this->config["first"]}</a> ";return $html;}/*设置上一页*/private function prev() {$html = "";if ($this->page == 1)$html.=" ".$this->config["prev"]." ";else$html.=" <a href="javascript:void(0)" onclick="showPage("{$this->uri}&page=" .

"")">{$this->config["prev"]}</a> ";//$html.=" <a href="{$this->uri}&page=".($this->page-1)."">{$this->config["prev"]}</a> ";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;$linkPage.=" <a href="javascript:void(0)" onclick="showPage("{$this->uri}&page={$page}")">{$page}</a> ";}$linkPage.=" {$this->page} ";for ($i = 1; $i <= $inum; $i++) {$page = $this->page + $i;if ($page <= $this->pageNum)$linkPage.=" <a href="javascript:void(0)" onclick="showPage("{$this->uri}&page={$page}")">{$page}</a> ";elsebreak;}return $linkPage;}/*设置下一页*/ private function next() {$html = "";if ($this->page == $this->pageNum)$html.=" ".$this->config["next"]." ";else$html.=" <a href="javascript:void(0)" onclick="showPage("{$this->uri}&page=" . ($this->page + 1) . "")">{$this->config["next"]}</a> ";//$html.=" <a href="{$this->uri}&page=".($this->page + 1)."">{$this->config["next"]}</a> ";return $html;}/*设置尾页*/private function last() {$html = "";if ($this->page == $this->pageNum)$html.=" ".$this->config["last"]." ";else$html.=" <a href="javascript:void(0)" onclick="showPage("{$this->uri}&page=" . ($this->pageNum) .

")?" . $this->pageNum . ":this.value;showPage("" . $this->uri . "&page="+page+"")}" value="" . $this->page . "" style="width:25px"><input type="button" value="GO" onclick="javascript:var page=(this.previousSibling.value>" . $this->pageNum . ")?" . $this->pageNum . ":this.previousSibling.value;showPage("" . $this->uri . "&page="+page+"")"> ";}//页面列表配置选项function fpage($display = array(0, 1, 2, 3, 4, 5, 6, 7, 8)) {$html[0] = " 共有<b>{$this->total}</b>{$this->config["header"]} ";$html[1] = " 每页显示<b>" . ($this->end() - $this->start() + 1) . "</b>条,本页<b>{$this->start()}-{$this->end()}</b>条 ";$html[2] = " <b>{$this->page}/{$this->pageNum}</b>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 = <<<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 $css;echo "<table><tr><td>序号</td><td>名称</td><td>数量</td><td>价格</td><td>时间</td></tr>";//1 引入分页类include "./Pagination.php";//2. 获得信息总条数$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 "<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>";
