Angular JSONP returning JSON_CALLBACK is not defined error

Ok, so this is very strange, but I eventually got it to work by changing the callback wrapper in the JSONP from JSON_CALLBACK(.......) to angular.callbacks._0 because that's the callback function angular kept trying to call instead of JSON_CALLBACK... very weird behavior.

Not being able to see your code, I can show you what worked for me a few days ago when working with JSONP and angular:

controller('YourCtrl', ['$scope', '$http', function($scope, $http) {
var url = "https://angularjs.org/greet.php?callback=JSON_CALLBACK&name=Brian"
$http.jsonp(url)
    .success(function(data) {
        $scope.greeting = data;
    });
}])

Then in the view, something like this should work:

<div ng-controller="YourCtrl">
{{greeting.name}} <br />
{{greeting.salutation}}
</div>

If this doesn't answer your question, try pasting in your code.

Brian I found out a method to make sure it detects ?callback=JSON_CALLBACK. When you request for the url, instead of putting the whole thing inside, you can write it this way, and it detects 100%:

$http({
  method: 'JSONP',
  url: 'https://angularjs.org/greet.php' + '?callback=JSON_CALLBACK' + '&name=Brian"'
});

The problem is in your Rest Answer or http json file on the bucket, need to be dynamic with the get(callback) parameter.

You need to detect the callback parameter and concat to the json to get the jsonp.

For Example:

1) http://example.com?callback=JSONP_CALLBACK
2) http://example.com?callback=OtherCallback
3) http://example.com?callback=JSONP_CALLBACK_OTHER

get the GET parameter "callback" and make your rest like this:

1) JSONP_CALLBACK({YOUR REST INFO})
2) OtherCallback({YOUR REST INFO})
3) JSONP_CALLBACK_OTHER({YOUR REST INFO}) 

Just use JSONP_CALLBACK instead of JSON_CALLBACK

Thanks.

Change your response from server by

angular.callbacks._0 ({"name":"Super Hero","salutation":"Namaste","greeting":"Namaste Super Hero!"});

instead of

JSON_CALLBACK ({"name":"Super Hero","salutation":"Pryvitannie","greeting":"Pryvitannie Super Hero!"});
