I have a FullCalendar with one recurring event, initialized by a RRule string. You can see a demo on code sandbox The Calendar is made editable so you can drag an event to a different location.
When the event is dropped, a function is called which is past a info
parameter.
Examining info.event.start
I see that the start time of the event has indeed changed.
Now what is the best way to retrieve the RRule string in order to store it in my database? Note that the DTSTART property in the string has to change too!
