What is the process through which AngularJS retrieves a value from an asynchronous call?

Check out this video,

https://www.youtube.com/watch?v=IRelx4-ISbs

In the code, you'll notice a line that says:

$scope.twitterResult = $scope.twitter.get({q:$scope.searchTerm});

It seems strange: the 'get' method of 'twitter' is clearly an asynchronous function, so how is it able to assign a value to $scope.twitterResult???

Here's the jsFiddle(No longer functional due to changes in the twitter API):

http://jsfiddle.net/johnlindquist/qmNvq/

Answer №1

This particular line of code,

$scope.twitter.get({q:$scope.searchTerm});
, brings back a defer object. In Angular's design, the view is set up to automatically update once the defer object is resolved. This setup provides a convenient feature for development purposes.

Answer №2

$scope.twitterResult = $scope.twitter.get({q:$scope.searchTerm});

Your coding technique is suitable for angular binding purposes only.

However, if you wish to retrieve real-time data, you are required to follow the format provided below:

If $scope.twitter represents a URL, then implement the following code snippet:

$http.get($scope.twitter, {q:$scope.searchTerm}).success(function (response) {
$scope.twitterResult=response;
}

Note: The usage of $http module is mandatory in the controller for this implementation.
