AngujarJS server-side pagination grand total items

问题:

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();
    }
}

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.

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

See the answer below for suggestions for the api.
