我想实现在一个AngujarJS应用服务器端分页，但还没有想出如何获得总计（而不是每个请求总计）在给定的JSON响应的物品，而无需做额外要求

I'm trying to implement server-side pagination on an AngujarJS app but haven't figured out how to get the grand total (not the per-request total) items in a given JSON response without having to do an additional request:

$scope.books = [];
$scope.limit = 3;
$scope.offset = 0;

$scope.search = function () {
    Books.query({ q: $scope.query, limit: $scope.limit, offset: $scope.offset },
        function (response) {
            $scope.books = response;
        }
    );
};

$scope.previous = function () {
    if ($scope.offset >= $scope.limit) {
        $scope.offset = $scope.offset - $scope.limit;
        $scope.search();
    }
}

$scope.next = function () {
    if ($scope.offset <= $scope.limit) {
        $scope.offset = $scope.offset + $scope.limit;
        $scope.search();
    }
}

我一直在寻找伟大的贡献指令，如 NG-表和 NG-格这已经实现了这个问题，以及其他有用的功能，但我只是希望能够从头开始实现这个功能，真正了解的基础知识。

I've been looking at great contributed directives such as ng-table and ng-grid which already implement this as well as other useful features but I just want to be able to implement this one functionality from scratch to really learn the basics.

听起来你与你的API超过角度挣扎。

Sounds like you are struggling with your api more than angular.
