Am I reading JSON correctly?

Question

JavaScript

I'm trying to read JSON into a variable, but I'm getting an error. Here is the code itself:

$scope.questions = $http.get('js/questions-content.json').success(function(response) {
         return response.data;
        // console.log(response.data);
    });

In theory, return should perform the assignment to $scope.questions, right?
The error is like this:

SyntaxError: Unexpected token ,
    at Object.parse (native)
    at fromJson

JSON itself is like this:
[{"id":1},{"id":2}]
What could be the problem?

Answer 1

If you call success, then the callback argument is no longer response, but response.data.
If you call then, then there is a response.
I could have tried deriving the success callback argument myself before asking.
Well, from a promise you get not a value, but only a promise. So the $scope.questions variable will contain the promise of the result, not the result itself.

$http.get('js/questions-content.json').success(function(questions) {
         $scope.questions =  questions;
    });
// Но лучше так:
$http.get('js/questions-content.json').then(function(response) {
         $scope.questions =  response.data;
    });

Because it's done asynchronously:

$http.get('js/questions-content.json').success(function(response) {
         return response.data;
        // console.log(response.data);
    });

When you make an assignment, the response object has not yet been received, so you need to do this:

$http.get('js/questions-content.json').success(function(response) {
         $scope.questions =  response.data;
    });
