Create a Javascript Callback function?
<p>i was wondering how to implement a callback into this piece of code</p>

<pre><code>MyClass.myMethod("sth.", myCallback);
function myCallback() { // do sth };
</code></pre>

<hr>

<pre><code>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 ?
            }
      });
}
</code></pre>

<p>}</p>
