Question

我是angularJS的新手。我正在使用离子框架进行android应用程序开发。在我的项目中，我调用webservice并获取其响应并将该响应附加到scope变量以获取视图上的数据。首次调用Web服务并按预期更新视图，但是当我再次调用不更新数据的服务时。由于某些参考丢失问题，似乎ng-repeat不起作用。但我无法找到解决方案。虽然我已经通过使用apply（）尝试了不同的解决方案，正如其中一个堆栈溢出帖子中提到的那样。以下是将web服务响应附加到范围变量的代码。

 $http(req).then(function (response) {
                  if (response.data.IsSuccess) {
                     console.log("data = " + JSON.stringify(response.data));
                     console.log('Response is '+response.data.IsSuccess);
                     $scope.companies = response.data.Response.Companies;
                  }

及以下是用于更新视图的代码行

<div class="col col-100" ng-repeat="company in companies">

任何帮助或建议

以下是调用webservice来更新我的数据的登录代码

function callLogInService(userName, password){
  console.log("user name is " +userName);
  console.log("password is " + password);

  var req = {
               method: 'POST',
               url: ApiUrl +  '/api/User/LoginUser',
               headers: {
                 'Content-Type': 'application/json'
               },
               data: {
               Email: userName,
               Password: password
               }
              }

                    $ionicLoading.show({
                        template: 'Signing in...'
                    });

                   $http(req).then(function (response) {
                        if (response.data.IsSuccess) {
                           console.log("data = " + JSON.stringify(response.data));
                           console.log('Response is '+response.data.IsSuccess);
                           var userID = response.data.Response.AppUserId;
                           var userName = response.data.Response.AppUserName;
                           setUserName(userName);
                           setUserId(userID);
                           $rootScope.appUserName;
                           var userIdFromSession = getUserID;
                           if(undefined == $rootScope.companyIdForSubscription
                                    || $rootScope.companyIdForSubscription == 0){
                            console.log("id is undefined for subscription");
                           } else {
                            console.log("company subscription id is " + $rootScope.companyIdForSubscription);
                            $scope.subscribe($rootScope.companyIdForSubscription);
                           }
                           $scope.close();
                           $scope.setVisibilityOdSideMenuIcons();
                           $scope.getAllCompanies();
                        }
                        else {
                          showErrorAlertDialogue(response.data.ErrorMessage);
                        }
                    }, function (reason) {
                    console.log('reason is ' + reason.data);
                    $log.info('reasonf log is' + reason) ;
                        showErrorAlertDialogue("Please check your internet connection.");
                    }).finally(function () {
                        console.log("finally is called");
                        $ionicLoading.hide();
                        $ionicPopup.close()
                    });
}

$ scope.getAllCompanies（）;这一行再次呼叫服务

ng-repeat不会更新我的模式数据
