复制代码 代码如下:

js 端 及判断 $(function(){ //var url=$(this)[0].location.href; //alert(url); goPageFirst(); $('#selpage').bind('change',goPage); }); //返回当前页数 function getNowPage() { return parseInt($('#nowPage').html()); } //返回每页显示的条数 function getPer() { return $('#perPage').val(); } //返回总记录数 function getTotal() { return parseInt($('#total').html()); } //返回总页数 function getAllPage() { return parseInt($('#allpage').html()); } //组合字符串参数 function getData(act) { var target=1; var now=getNowPage()+1; var per=getPer(); var sum=getTotal(); var allpage=getAllPage(); switch(act) { case 'first': target=1; break; case 'prev': target=now>1?now-1:1; break; case 'next': target=now+1>allpage?now:1; break; case 'last': target=allpage>0?allpage:1; break; case 'constans': target=$('#selpage').val()>0?$('#selpage').val():1; default : target=1; } var data="check="+act+"&nowpage="+now+"&perpage="+per+'&target='+target; alert(data); return data; } //执行第一页 function goPageFirst() { var param=getData('first'); http_post(param); } //执行上一页 function goPagePrev() { var param=getData('prev'); http_post(param); } //执行下一页 function goPageNext() { var param=getData('next'); http_post(param); } //执行最后页 function goPageLast() { var param=getData('last'); http_post(param); } //选中到指定页面 function goPage() { var param=getData('constans'); http_post(param); } //post 请求数据加载 function http_post(db) { $.post('./mysql.php',db,function(data){ responseAjax(data); },'text'); } //返回数据的调处理 function responseAjax(msg) { //alert(msg); //alert(msg.content); //$('#listDiv').html(msg.content); $('#listDiv').html(msg); } server端 判断及实现 //@autor 499188204@qq.com mb_internal_encoding('gb2312'); $con=mysql_connect("127.0.0.1","root","12345678") or die("连接失败"); $m=mysql_select_db("ec",$con); $sql = 'SELECT `attr_id`,`cat_id`,`attr_name` FROM `ecs_attribute` '; $rs = mysql_query($sql ); $count = mysql_num_rows($rs); //返回记录总数 //echo $count; //总记录数 //每页的记录数 10 //求总页数 ceil($count/10) //echo ' '; if(!isset($_POST['check'])) { $set['id']=0; die('no access please!'); } if(isset($_POST['perpage']) && $_POST['perpage']>0 ) { $per=$_POST['perpage']; } else { $per=15; } $page = ceil($count/$per); //echo $page; if(!isset($_POST['nowpage'])) { $nowPage=1; } else { $nowPage = $_POST['nowpage']; } $start = ($nowPage-1)*$per+1; $sql = 'select `attr_id`,`cat_id`,`attr_name` from `ecs_attribute` limit '.$start.','. $per; //$sql = 'select `attr_id`,`cat_id`,`attr_name` from `ecs_attribute` limit 10 offset 20'; $rs = mysql_query($sql );
