NodeJS return JSONP NOT using express

Question

Im trying to call my nodejs server and show the results from an angularjs app. ive been following an example, but when i change the example code for my code, it always calls the error callback. i have a feeling its something wrong with my server, but i cant make it work, its nodejs without express or other libraries, and all other answers involve using express. how can i make it work without using express?

the code in angularjs, where i call the server:

app.controller('Main', function ($scope, $http) {
    $scope.init = function() {        
        //var api = 'http://api.trakt.tv/calendar/premieres.json/7c989229f2fa626832e7576eb59820e9/20131103/30/?callback=JSON_CALLBACK';        
        $http.jsonp('http://localhost:8888/selectAllLocations?callback=JSON_CALLBACK').success(function(data) {
            console.log(data);
        }).error(function(error) {
            console.log('My error: ' + error);
        });
    };

});

if i use the value in the var api, the result is ok and success is called, not with mine.

This is the code in my nodejs server.

var result = sequelize.query(query, null, options, parameters)
.success(function (rows) {        
    if (type == 'select') {
        response.writeHead(200, { "Content-Type": "application/json" });
        response.write(JSON.stringify(rows));
        response.end();
    } else if (type == 'modify') {
        response.writeHead(200, { "Content-Type": "text/html" });
        response.write("Query was successful");
        response.end();
    }
}
).error(function (e) {
    console.log("An error occured: ", e);
    response.writeHead(404, { "Content-Type": "text/html" });
    response.write("There was an error man, shits on fire yo ---> " + e);
    response.end();
}
);

Im pretty sure i have to wrap the json result in a function, but i dont know how, and i cant even know the function name, as this is all i get in my server:

path: /selectAllLocations params: {"callback":"angular.callbacks._0"}

I understand im returning the pure json, and i can see it in chrome in my response, so, there is something preventing it from calling the success function. Can somebody point me in the right direction?

函数名称被指定为callback参数。

 response.write(params.callback + '(' + JSON.stringify(rows) + ')');
