javascript - Removing all the eventSources in fullCalendar -

i have 2 types of events in fullcalendar. few fetched eventsources using :

    $('calendar').fullcalendar('addeventsource' , 'source')  

and few created user. using

    $('calendar').fullcalendar('renderevent', eventdata, true) 

now upon clicking button want remove events obtained eventsources , retain created user.

i tried doing :

     $('calendar').fullcalendar('removeeventsource' , function(e){ return true ; } ) ;  

but doesn't work. how achieve doing job ?

i did want in recent project. fullcalendar supports nonstandard fields.

non-standard fields

in addition fields above, may include own non-standard fields in each event object. fullcalendar not modify or delete these fields. example, developers include description field use in callbacks such eventrender.

source

so like

//save user created event $('#calendar').fullcalendar('renderevent', {     title: title,     end: end,     start: start,                    editable : true,     //nonstandard field     isusercreated: true,     description: description,                }); 

then remove events hasn't been created user

//get client events var allevents = $('#calendar').fullcalendar('clientevents');  var usereventids= [];  //find ever non usercreated event , push id array $.each(allevents,function(index, value){     if(value.isusercreated !== true){     usereventids.push(value._id);     } });  //remove events ids of non usercreated events $('#calendar').fullcalendar( 'removeevents', usereventids); 

or if need less control (as @a1rpun suggested)

 $('#calendar').fullcalendar( 'removeevents', function(e){ return !e.isusercreated});
