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"'
});
