        }

        'afterLoadAll': null,
        'scrollTarget': null,
        'heightOffset': 0
    };
})(jQuery);

2.调用

加载页面：

<div class="row" id="pagination_container"></div>
    <div id="pagination_loading" style="display: none;">加载中...</div>
    <div id="pagination_nomore" style="display: none;">已经全部加载</div>

调用js:

<script type="text/javascript">
        $(function () {
            $('#pagination_container').scrollPagination({
                'contentPage': '/order/ajax_diliver_list',
                'contentData': {status: '', pnt: '', pnm:<?= $pageRows;?>},
                'scrollTarget': $(window),
                'heightOffset': 20,
                'loadContentData': function () {
                    var pagePoint = $('#pagination_container').children().children().children().last().children('.panel-success').html();
                    return {pnt: pagePoint}
                },
                'beforeLoad': function () {
                    $('#pagination_loading').show();
                },
                'afterLoad': function (elementsLoaded) {
                    $('#pagination_loading').hide();
                    if ($('#pagination_container').children().size() > 10000) {
                        stopLoad();
                    }
                },
                'afterLoadAll': function () {
                    stopLoad();
                }
            });
            function stopLoad() {
                $('#pagination_container').stopScrollPagination();//停止加载
                $('#pagination_nomore').fadeIn().delay(3000).fadeOut();
            };


        });


    </script>

服务器端：

public function ajaxDeliverViewAction()
    {
        $pagePoint = $this->getParam('pnt', 'String', '');
        $status    = $this->getParam('status', 'String', '');
        $dayTime   = $this->getParam('day', 'String', '');
        $pageSize  = Serve_Env_Define::PAGE_SIZE;

       $search['serve_user_id'] = $this->user->id;

        $orderARs = System_Module_Serve::getOrderListBySearch($search, $pageSize, $pagePoint);$this->render('ajaxDeliverView', compact('orderARs', 'addressLists', 'status'));
    }

public static function getOrderListBySearch($search, $limit, $pagePoint)
    {
        $da = self::combineConditions($search);

        $da->sort('id', 'DESC');

        if (!empty($pagePoint)) {
            $da->filterByOp('id', '<', $pagePoint);
        }

        $orderARs = $da->limit($limit)->find();

        if (empty($orderARs)) {
            return array();
        }
return $orderARs;
    }

private static function combineConditions($search)
    {
        $da = System_Model_ServeOrder::dataAccess();
        foreach ($search as $field => $value) {
            if ($field == 'startDate') {
                $da->filterByOp('created', '>=', strtotime($value . " 00:00:00"));
            } elseif ($field == 'endDate') {
                $da->filterByOp('created', '<=', strtotime($value . " 23:59:59"));
            } elseif ($field == 'phone') {
                $memberAR = System_Module_Passport::getInfoByPhone($value);
                if (empty($memberAR)) {
                    $da->filter('member_id', 0);
                } else {
                    $da->filter('member_id', $memberAR->id);
                }
            } elseif ($field == 'requestTime') {
                $da->filterByOp('updated', '>=', $search['requestTime']);
            } else {
                $da->filter($field, $value);
            }
        }

        return $da;
    }

public function filterByOp($name, $op, $value)
    {
        $this->filterNames[]  = $name;
        $this->filterOps[]    = $op;
        $this->filterValues[] = $value;

        return $this;
    }

注：scrollpagination.js代码为全的，调用的js代码可以修改您要修改的请求路径，和

'contentData': {status: '', pnt: '', pnm:<?= $pageRows;?>},里的参数，
另外，

'loadContentData': function () {
                    var pagePoint = $('#pagination_container').children().children().children().last().children('.panel-success').html();
                    return {pnt: pagePoint}
                },
pagePoint是要找到根据您自身页面当中找到最后一个内容模块,否则会有重复信息加载。
