Angular - 将变量公开给控制器

Question

所以我有一个控制器调用工厂然后设置 "variableToExpose"。当 I console.log($scope.variableToExpose) 出现时未定义。将该变量公开给控制器的最佳方式是什么？

.controller('SomeCtrl', function($scope, $http, $state, SomeFactory) {

  console.log($scope.variableToExpose); //returns undefined

  SomeFactory.getRequest($id).then(function(response){
      $scope.variableToExpose = varFromGetRequest;
  }
}

谢谢！

将 console.log 移到成功处理程序中。

app.controller('SomeCtrl', function($scope, $http, $state, SomeFactory) {


  //console.log($scope.variableToExpose); //returns undefined

  SomeFactory.getRequest($id).then(function successHandler(response){
      //$scope.variableToExpose = varFromGetRequest;
      $scope.variableToExpose = response;
      console.log($scope.variableToExpose);
  });
});

promise 的 .then 方法在 promise 已解决后调用成功处理程序函数。 $q 服务以承诺的解析值作为唯一参数调用该函数。
