                                scope.conf.currentPage - 1,
                                scope.conf.currentPage,
                                scope.conf.currentPage + 1
                            ];
                        } else if (scope.conf.currentPage == 1 && scope.conf.totalPage > 1) {
                            scope.conf.pages = [
                                scope.conf.currentPage,
                                scope.conf.currentPage + 1
                            ];
                        } else if (scope.conf.currentPage == scope.conf.totalPage && scope.conf.totalPage > 1) {
                            scope.conf.pages = [
                                scope.conf.currentPage - 1,
                                scope.conf.currentPage
                            ];
                        }
                    };
    
                    //指令加载完后当即查询
                    scope.query();
                }
            };
        }]);

为了代码集中一点, 我把ajaxservice定义在了内部. 
指令基本包含分页所需功能,且不需修改, 下次就能够直接引用.

应用

index.html

<pagination list="businesses" url="/business/select" event="event-pagination-query-bp" method="POST"
                    request-param="requestParam"
                    request-data="requestData">
        </pagination>

示例代码中, list参数是双向绑定的列表数据, businesses就是页面table绑定的ng-repeat循环的列表集合, url是后台接口, event是事件名, method是接口方法,GET or POST, request-param就是请求参数,request-data就是请求体.

controller.js

//分页请求参数
    $scope.requestParam = {};
    //分页请求对象(模糊查询时,对象属性能够为列表数据的字段)
    $scope.requestData = {};

    /**
     * 广播通知分页指令
     */
    $scope.query = function () {
        $scope.$broadcast('event-pagination-query-bp', 'query');
    };

当新增数据或者更新数据后, 能够调用controller里的query方法, 通知指令进行分页查询
