php怎么实现无刷新分页效果

php+ajax实现无刷新分页实现方法具体如下：

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

$html.=" a href='javascript:void(0)' onclick='showPage(\"{$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=" . ($this-page - 1) . "\")'{$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 ";

else

break;

}

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-config["last"]}/a ";

//$html.=" a href='{$this-uri}page=.(this-pageNum).'{$this-config["last"]}/a ";

return $html;

}

/*设置页面跳转*/

private function goPage() {

return

' input type="text" onkeydown="javascript:if(event.keyCode==13){var page=(this.value' . $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

trtd序号/tdtd名称/tdtd数量/tdtd价格/tdtd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 "trtd colspan=5".$pagelist."/td/tr";

echo "/table";
