Question

i was wondering how to implement a callback into this piece of code

MyClass.myMethod("sth.", myCallback);
function myCallback() { // do sth };

---

var MyClass = {

myMethod : function(params, callback) {

    // do some stuff

    FB.method: 'sth.',
       'perms': 'sth.'
       'display': 'iframe'
      },
      function(response) {

            if (response.perms != null) {
                // How to pass response to callback ?
            } else {
                // How to pass response to callback ?
            }
      });
}

}

All you have to do is call the callback function the normal way. In this case you would just do callback(response).

var MyClass = {

myMethod : function(params, callback) {

// do some stuff

FB.method: { 'sth.',
   'perms': 'sth.'
   'display': 'iframe'
  },
  function(response) {

        if (response.perms != null) {
            // How to pass response to callback ?
            // Easy as:
            callback(response);
        } else {
            // How to pass response to callback ?
            // Again:
            callback(response);
        }
  });
}
