eventSourceSuccess
A function that gets called when fetching succeeds. It can transform the response. Gets called for any type of Event source.
function( rawEvents, xhr )
Will receive two arguments, the raw response content and an XHR if applicable. The function can return a new array of parsable Event objects that will be used instead of the received response. Example:
eventSourceSuccess: function(content, xhr) {
return content.eventArray;
}
This is useful if your server returns a wrapper object. If you are already receiving an array, and merely want to transform each individual item, use eventDataTransform instead.
