title: Cross domain JSON feed for jQuery FullCalendar plugin
body: <p>I'm using PHP to pull the events from a FullCalendar as a JSON feed but I need to support multiple domains.  I need a querystring variable to specify which calendar to pull events from... is this causing a problem?  Here's the FullCalendar init code:</p>
  
  <pre><code>$('#full-calendar".$id."').fullCalendar({
     editable: false,
     events:'http://www.mydomain.com/resources/include/calendar-events.php?cal=".$id."',
     loading: function(bool) {
         if (bool) $('#loading').show();
         else $('#loading').hide();
     }
  });
  </code></pre>
  
  <p>The documentation says "If you need to access a feed that is in a different domain, you can use JSONP with a ? in your URL (see the JSONP discussion in <code>$.ajax</code>)."  </p>
  
  <p>But I'm not exactly sure how to do that.</p>
  
  <p>Thanks for your help in advance.</p>
