js 移动端上拉刷新（基于ng1）

//分页下拉
var ajaxScroll = function() {
    var screenHeight = window.screen.height;
    $(document).scroll(function() {

                $scope.tips = '正在加载数据...';
                setTimeout(function() {
                    loadData($scope.state, $scope.pageNo);
                }, 500);
                $scope.$apply();
            }
            $(document).unbind('scroll');
