Asp.net mvc 模型Id已传递到Angular Ctrl

我有一个使用下面控制器的MVV视图，我需要以某种方式将产品Id，即Model.Id传递给控制器。 我已经尝试过$scope.init，但在我进行第一次Ajax调用时，它显示为null，我怀疑这个Ajax get是在启动init并设置产品id之前启动的，因此Ajax失败，因为调用时productId为null。我是新来的，所以如果这是一个小学生的错误，我道歉

控制器和HTML如下所示

 angular.module('askQuestions', [])
 .controller('questionController', function ($scope, $http) {
  $scope.loading = true;
  $scope.addMode = false;
  $scope.replyMode = false;
  $scope.parentClicked = 0;

  $scope.init = function (productId) {
      //This function is sort of private constructor for controller
      $scope.productId = productId;
      $scope.getUrl = '/Api/GetProductQuestions/' + $scope.productId;

  };


  //Used to display the data
  //$http.get('/Api/GetAllManufacturers?apiToken=6a5ce02e-0506-0a41-2f50-37327080662f').success(function (data) {
  $http.get($scope.getUrl).success(function (data) {


      $scope.questions = data;
      $scope.loading = false;

  })
  .error(function () {
      $scope.error = "An Error has occured while loading questions!";
      $scope.loading = false;
     // alert($scope.getUrl);
  });

}))

您的

$http.get

在控制器的实例化中进行评估。实例化在init之前进行，因此已经进行了ajax调用。您可以通过将

$http.get

也包装到函数中来轻松解决此问题：

$scope.init = function (productId) {
    //This function is sort of private constructor for controller
    $scope.productId = productId;
    $scope.getUrl = '/Api/GetProductQuestions/' + $scope.productId;
    getData();
};

var getData = function() {
    $http.get($scope.getUrl)
        .success(function (data) {
            // success
            $scope.questions = data;
        })
        .error(function () {
            // error
            $scope.error = "An Error has occured while loading questions!";
        })
        .finally(function () {
            // always
            $scope.loading = false;
        });
}

$scope.init = function (productId) {
    //This function is sort of private constructor for controller
    $scope.productId = productId;
    $scope.getUrl = '/Api/GetProductQuestions/' + $scope.productId;
    getData();
};

var getData = function() {
    $http.get($scope.getUrl)
        .success(function (data) {
            // success
            $scope.questions = data;
        })
        .error(function () {
            // error
            $scope.error = "An Error has occured while loading questions!";
        })
        .finally(function () {
            // always
            $scope.loading = false;
        });
}
