ajax无刷新分页效果

1、制作传统分页效果

        table {width:700px; border:1px solid black; margin:auto; border-collapse:collapse;}
        td {border:1px solid black; }
    
    
eof;

//① 引入分页类
include "./Page.class.php";
$current = isset($_GET['page']) ? $_GET['page'] : 1;

//获取每页显示的记录数
$pagesize = 7;
$offset = ($current - 1) * $pagesize;
$sql = "select * from sw_goods limit $offset, $pagesize";
$sql2 = "select * from sw_goods";
$types = mysql_query($sql);
//获取总的记录数
$temp_i = mysql_query($sql2);
$total = mysql_num_rows($temp_i);
$page = new Page($total, $pagesize, $current, 'data.php', array());
$pageinfo = $page->showPage();


$num = ($current - 1) * $pagesize;
while($rst = mysql_fetch_assoc($types)){
    printf("");
    printf("",$num);
    printf("",$rst['goods_name']);
    printf("",$rst['goods_price']);
    printf("",$rst['goods_number']);
    printf("",$rst['goods_weight']);
    printf("");
    $temp_i++;
    $num++;
}
printf("",$pageinfo);
echo "

        
序号
名称
价格
数量
重量
%d
%s
%s
%d
%d
%s
";

效果图：

2、ajax实现异步分页效果

实现异步部分的php代码：

        table {width:700px; border:1px solid black; margin:auto; border-collapse:collapse;}
        td {border:1px solid black; }
    
    
eof;

//① 引入分页类
include "./page.class.php";

//② 获得总条数、每页显示条数
$sql = "select * from sw_goods";
$qry = mysql_query($sql);
$total = mysql_num_rows($qry); //总条数
$per = 7;//每页条数

//③ 实例化分页类对象
$page = new Page($total, $per);

//④ 设置sql语句获得每页信息
//$page->limit:分页类会根据当前页码参数自动把 "limit 偏移量,长度" 信息给拼装好
$sql3 = "select * from sw_goods order by goods_id ".$page->limit;
$qry3 = mysql_query($sql3);

//⑤ 获得页码列表信息
$page_list = $page -> fpage(array(3,4,5,6,7,8));

$page_num = isset($_GET['page'])?$_GET['page']:1;
$num = ($page_num-1)*$per+1;

while($rst3 = mysql_fetch_assoc($qry3)){
    printf("");
    printf("",$num);
    printf("",$rst3['goods_name']);
    printf("",$rst3['goods_price']);
    printf("",$rst3['goods_number']);
    printf("",$rst3['goods_weight']);
    printf("");
    $num++;
}
printf("",$page_list);
echo "

        
序号
名称
价格
数量
重量
%d
%s
%s
%d
%d
%s
";

实现异步的html代码：

    
        
        
        
        

        
        
    
    
        
ajax无刷新分页
        

    

分页类：

         if(isset($parse["query"])){
            parse_str($parse['query'],$params);
            unset($params["page"]);
