Question

我尝试使用$ http的方法，因为我的代码在请求结果返回之前运行。所以我的响应参数是未定义的。

var reqgetcustomers = $http({
    url: 'api/customers/GetNbCustomer',
    params: {
        'lastName': lastName,
        'firstName': firstName,
        'address': address,
        'town': town,
        'zipCode': zipCode,
        'skip': -1,
        'take': -1
    }
};

reqgetcustomers.then(function (dataresult) {
    $scope.itemCount = dataresult.data;
    var nbPage = Math.ceil($scope.itemCount / $scope.numPerPage);
    locker.put('nbPage', nbPage);
    console.log('locker nbPage before=> ', locker.get('nbPage'));
    console.log('itemCount => ', $scope.itemCount);
});

我之后使用请求的结果，但是nbPage变量未定义。

欢迎任何帮助。

感谢。

我成功了。这是我的新代码，如果它可以帮助某人：

    //create the promise
    function getCustomersRequest(lastName, firstName, address, town, zipCode, skip, take)
    {
        var deferred = $q.defer();
        var reqgetcustomers = $http({
            url: 'api/customers/GetNbCustomer',
            params: { 
                'lastName': lastName,
                'firstName': firstName, 
                'address': address,
                'town': town,
                'zipCode': zipCode,
                'skip': -1,
                'take': -1 
            } 
         });
         reqgetcustomers.success(function (dataResult) {
             deferred.resolve(dataResult);
         });
         return deferred.promise;
    }

    //new method with promise
    function GetListFiltered(lastName, firstName, address, town, zipCode, skip, take) {
        var deferred = $q.defer();
        var reqSearchCustomers = $http({ 
            url: '/api/customers/GetFilteredList',
            params: { 
                'lastName': lastName,
                'firstName': firstName, 
                'address': address,
                'town': town, 
                'zipCode': zipCode,
                'skip': skip,
                'take': take 
            } 
        });
        reqSearchCustomers.success(function (dataResult) {
            deferred.resolve(dataResult);
            $scope.customers = dataResult;
        });
        var myPromise = getCustomersRequest(lastName, firstName, address, town, zipCode, skip, take);
        myPromise.then(function (resolve) {
            $scope.itemCount = resolve;
            locker.put('itemCount', resolve);
            locker.put('skip', ((locker.get('currentPage') - 1) * $scope.numPerPage));
            var nbPage = Math.ceil(locker.get('itemCount') / $scope.numPerPage);
            locker.put('nbPage', nbPage);
            $scope.skip = locker.get('skip');
            $scope.nbPage = locker.get('nbPage');
    }
    GetListFiltered(locker.get('lastName'), locker.get('firstName'), locker.get('address'), locker.get('town'), locker.get('zipCode'), $scope.skip, $scope.numPerPage);

然后是$ http请求的Angularjs方法
