jquery ajax分页写法

jquery ajax分页写法
我用的是laypage插件

前端代码

        function demo(curr) {
            $.getJSON('/home/index/getinfo', {
                page: curr || 1 //向服务端传的参数,此处只是演示
            }, function (res) {
                var html = '';
                var list = res.data.list;
                $.each(list, function (k, v) {
                    html += '<div';
                    if(k%2==0){
                        html += ' style="margin-left:0px;"';
                    }
                    html += ' class="perinfocontent" onclick="window.location.href=\'content.html?id='+v['id']+'\'">';
                    html += '<img src="'+v['fengmiantu']+'" alt="" class="pic">';
                    html += '<div class="infos">';
                    html += '<div class="title">'+v['title']+'</div>';
                    html += '<div class="tiyao">'+v['content']+'</div>';
                    html += '<div class="publishtime">2017 / 1 / 23</div>';
                    html += '</div>';
                    html += '</div>';
                });

                $('.infocontent').html(html);

                //显示分页
                laypage({
                    cont: $('#page3'), //容器。值支持id名、原生dom对象,jquery对象,
                    pages: res.data.pagecount, //总页数
                    skip: true, //是否开启跳页
                    skin: 'molv',
                    curr: curr || 1, //当前页
                    jump: function (obj, first) { //触发分页后的回调
                        if (!first) { //点击跳页触发函数自身,并传递当前页:obj.curr

                        demo(obj.curr);
                        }
                    }
                });

            });
        };
//运行
        demo();

PHP代码

    public function getinfo(){
        $page = intval($_GET['page']);
     
        if(empty($page)){
            $page=1;
        }
        $startpos=$page-1;
        //返回每页的数据
        $percount = 8;
        $VModel = new HuanShanVoteModel();
        $sql = 'select * from wz_content order by id desc limit '.$startpos*$percount.',' . $percount;

        $result = $VModel->query($sql);
        foreach ($result as $k => $v) {
            $result[$k]['content'] = substr(stripHTML(htmlspecialchars_decode($v['content'])), 0, 30) . '......';
            $result[$k]['time'] = date('Y / M / D', $v['time']);
        }

        //返回总页码数
        $VModel = new HuanShanVoteModel();
        $sql = 'select title,content from wz_content';
        $alllist = $VModel->query($sql);
        $count = count($alllist);
        $pagecount = ceil($count / $percount);

        echo json_encode(array('success'=>1,'msg'=>'查询成功','data' => array('pagecount' => $pagecount, 'list' => $result)));
        exit();
    }
