Fullcalendar V4 - clear all events

Question

I'm loading dynamic events from a JSON source, but each time I click a different room, I want to clear all the events prior to fetching the new ones

I have attempted to clear the eventSource but to no avail

var eventSource = calendar.getEventSources()
eventSource.remove();

which results in an error:

Uncaught TypeError: eventSource.remove is not a function

I have previously been using V3, but upgraded to V4 and the documentation is a little hard to follow on how to clear the events.

Answer 1

You are absolutely spot on, I'm having a particularly slow day on picking things up!

var eventSources = calendar.getEventSources(); 
var len = eventSources.length;
for (var i = 0; i < len; i++) { 
    eventSources[i].remove(); 
} 

Was the solution, as suggested by ADyson.
