Fullcalendar 4, when using eventRender i get error Failure parsing JSON

I am using FullCalendar 4 and i have setup the Calendar Object in my script

When i have eventRender setup in the code the calendar stops fetching events from my source and it shows the eventSources>failure dialog that i added in the function.
When i remove the eventRender part of the script the calendar object renders perfectly and I am able to see all the events from my database.
Could anybody point out where I am going wrong with the coding?
would really like to get the eventRender part working so i can change the background color of events that are set, also in addition, how would i add in events of my own after the source has fetched the events from the server? I want to do this so I can fill in time slots that are missing in the calendar so the user can select a free slot to create a booking.
Many Thanks
Edit I took out the tool tip code I found in the full calendar docs and replaced it with ui tool tip instead, that is now working. What is the procedure for adding in my own events?

events with rrule plugin is not updating after drag/drop on change view grid fullcalendar v4

I am currently working on Fullcalendar v4 with rrule plugin
I have this code
var calendarEl = document.getElementById('calendardemo');
var calendar = new FullCalendar.Calendar(calendarEl, {
plugins: ['interaction', 'dayGrid', 'timeGrid', 'momentTimezone', 'rrule', 'list'],
header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay'
},
editable: true,
events: [
{ // standard property
title: 'This is sample event',
start: '2019-12-29',
end: '2019-12-31'
},
{
title: 'event with rrule plugin',
rrule: {
freq: 'weekly',
interval: 5,
byweekday: [ 'mo', 'fr' ],
dtstart: '2019-12-29T10:30:00',
until: '2020-12-31'
}
}
]
});
calendar.render();
please note:
{ // this is the standard (No issues)
title: 'This is sample event',
start: '2019-12-29',
end: '2019-12-31'
}
{ // Not updating on change view
title: 'event with rrule plugin',
rrule: {
freq: 'weekly',
interval: 5,
byweekday: [ 'mo', 'fr' ],
dtstart: '2019-12-29T10:30:00',
until: '2020-12-31'
}
}
Link to a demo
Now when I drag & drop "This is sample event" then change view grid or click < > it stays updated. but when I drag & drop "event with rrule plugin" then change view grid or click < > it's not updated. it just stays where it was loaded in first load. Please help. Thanks !

You might have to add a form that would allow a user to change repeated rules when they begin to drag them. Otherwise, could you describe expected behaviour after the user drops repeated event on another date. What changes would be applied to a rule?

FullCalendar v3 - Change Event Source on View Change

I'm using FullCalendar v3 (latest) with a PHP backend.
I'm returning a JSON array from the backend broken up into 2 arrays. The first contains event details (a list of orders for the day, with the order# as the title), and the second contains a daily summary (with a sum of orders and work hours as the title). The array looks like this:
{"events":[{"id":709989,"item_no":"ABC123","title":709989,"color":"red","start":"2019-05-14","end":"2019-05-14","allDay":true,"total_hours":3,"remaining_hours":1.5},{"id":709990,"title":709990,"item_no":"ABC345","color":"red","start":"2019-05-15","end":"2019-05-15","allDay":true,"total_hours":5.7,"remaining_hours":3.2}],"summary":[{"id":338823,"title":"Orders: 14\rHours:28.33\rRemaining Hours:13.33","start":"2019-05-14","end":"2019-05-14","allDay":true},{"id":338824,"title":"Orders: 3\rHours:14.2\rRemaining Hours: 12.2","start":"2019-05-15","end":"2019-05-15","allDay":true}]}
There are other properties but these are the basics.
What I'm trying to do is change the array that's used as the event source depending upon which view is selected. I've tried custom event rendering, custom view rendering, multiple event sources (even though it's expensive from a data point-of-view, the # of records aren't so numerous that it greatly effects performance).
The custom view name is customMonth. When this view is selected, I just want to render the summary data (from the summary array). If any of the other views are selected (I'm using basicWeek, month and listWeek), render the events array.
let vname;
$("#calendar").fullCalendar({
defaultDate: new Date(),
defaultView: 'month',
eventRender: function(eventObj, $el, view) {
let n = view.name;
if(n=='customMonth')
{
vname = 'customMonth';
$el.popover({
title: eventObj.title,
content: eventObj.total_hours,
html: true,
trigger: 'hover',
placement: 'auto',
container: 'body'
});
} else {
vname = n;
$el.popover({
title: "Work Order " + eventObj.title,
content: '<strong>Item#</strong>: ' + eventObj.item_no + '<br />' + '<strong>Total Hours</strong>: ' + eventObj.total_hours + '<br />' + '<strong>Remaining Hours</strong>: ' + eventObj.remaining_hours,
html: true,
trigger: 'hover',
placement: 'auto',
container: 'body'
});
}
},
events: function(start, end, timezone, callback){
$.ajax({
url: '/myendpoint',
type: 'POST',
dataType: 'json',
data: {
action: 'get-calendar-summary',
cell: selected_cell
},
success: function(data) {
let events = [];
if(vname=='customMonth') {
obj = data.summary;
$(obj).each(function() {
events.push({
id: $(this).attr('id'),
title: $(this).attr('title'),
start: $(this).attr('dept_due_dt'),
end: $(this).attr('dept_due_dt'),
total_hours: $(this).attr('total_hours'),
remaining_hours: $(this).attr('remaining_hours'),
order_count: $(this).attr('day_order_count'),
has_late_order: $(this).attr('has_late_order'),
allDay: true,
earliest_date: $(this).attr('earliest_date')
});
});
} else {
obj = data.event_results;
$(obj).each(function() {
events.push({
id: $(this).attr('id'),
color: $(this).attr('color'),
title: $(this).attr('title'),
start: $(this).attr('start'),
end: $(this).attr('end'),
earliest_date: $(this).attr('earliest_date'),
item_no: $(this).attr('item_no'),
total_hours: $(this).attr('total_hours'),
remaining_hours: $(this).attr('remaining_hours')
});
});
}
callback(events);
},
error: function(err) {
console.log(err);
}
});
},
views: {
customMonth: {
type: 'month',
buttonText: 'overview'
}
},
viewRender: function(view, el) {
let lastview;
if(view.name=='customMonth') {
if(lastview == 'customMonth') {
return false;
} else {
view.unrenderDates();
view.renderDates();
$("#calendar").fullCalendar('rerenderEvents');
}
lastview = 'customMonth';
} else {
if(lastview=='customMonth') {
view.unrenderDates();
view.renderDates();
$("#calendar").fullCalendar('rerenderEvents');
}
lastview = view.name;
}
},
header: {
left: 'prev,next',
center: 'title',
right: 'basicWeek,month,listWeek,customMonth'
},
themeSystem: 'bootstrap3',
timeZone: false,
weekends: false,
//tried with and without lazyFetching
lazyFetching: true
});
I'd appreciate any guidance. I've searched StackOverflow (this seems like the closest, but I followed exactly and it didn't work (switching out viewDisplay for viewRender)), Github, and all other sources I can think of.

Here a simplified example of what you are trying to achieve (I hope I well understand your problem) :
HTML :
<div id='calendar'></div>
Javascript :
$(document).ready(function() {
var ev1 = {"events":[{"id":709989,"item_no":"ABC123","title":'Event from source 1',"color":"red","start":"2019-05-14","end":"2019-05-14","allDay":true,"total_hours":3,"remaining_hours":1.5}]};
var ev2 = {"events":[{"id":709989,"item_no":"ABC123","title":'Event from source 2',"color":"blue","start":"2019-05-14","end":"2019-05-14","allDay":true,"total_hours":3,"remaining_hours":1.5}]};
$('#calendar').fullCalendar({
defaultDate: new Date(),
defaultView: 'month',
viewRender: function(view) {
if(view.type === 'basicWeek') {
$('#calendar').fullCalendar( 'removeEventSource', ev1 );
$('#calendar').fullCalendar( 'addEventSource', ev2 );
return;
}
},
header: {
left: 'prev,next',
center: 'title',
right: 'basicWeek,month,listWeek,customMonth'
},
});
$('#calendar').fullCalendar( 'addEventSource', ev1 );
});
And the codepen to try it.
It uses the callback function viewRender() to detect when a view change and addEventSource()/removeEventSource() to change the data. So when you change the view from month to week it will change the source events.

Is there a way to implement an event filter in Fullcalendar v4 using custom buttons?

I am migrating from Bootstrap DateTimePicker to Fullcalendar v4 and my problem is filtering events.
With DateTimePicker, I had much more freedom to manipulate with events shown on calendar (it also seems that Fullcalendar v3 had more freedom than v4).
I can't find a method that would just place events from array to screen. So far, this is how my code looks
var calendar = new FullCalendar.Calendar(element, {
plugins: [ 'dayGrid', 'timeGrid', 'list', 'interaction', 'bootstrap' ],
themeSystem: 'bootstrap',
events : function(info, successCallback, failureCallback) {
console.log('events');
self.eventsLoadingRequest(true);
calendarService.getEvents(moment(info.start), moment(info.end)).then(
function(result) {
ko.utils.arrayPushAll(self.events, self.parseByType(result));
self.eventsLoadingRequest(false);
successCallback(ko.utils.arrayMap(self.events(), function(item) { return item.serialize() }));
},
function(error) {
}
);
},
customButtons: {
filterEvents: {
text: 'Events',
click: function() {
self.eventsFilter(true, false);
}
},
filterAll: {
text: 'All',
click: function() {
self.eventsFilter(true, true);
}
},
filterGoals: {
text: 'Goals',
click: function() {
self.eventsFilter(false, true);
}
}
},
header: {
left: 'title',
right: 'prev,today,next dayGridMonth,timeGridWeek,timeGridDay,listWeek, filterEvents,filterAll,filterGoals'
},
navLinks: true,
editable: true,
eventLimit: true
});
And eventsFilter function merges two arrays into one. Is it possible to manually call events : function(info, successCallback, failureCallback)?
I want to avoid using multiple streams and reloading events to apply filter.

FullCalendar not events curl up

Why are my full calendar event does not curl up. If I have more than three events should curl up and show at the bottom of the "more events". FullCalendar downloaded from the repository adesigns / calendar-bundle. I have this:
I need this:
This is my code.I added a piece of code at the end of the function but is not working:
$(document).ready(function () {
$(function () {
var date = new Date();
var d = date.getDate();
var m = date.getMonth();
var y = date.getFullYear();
$('#calendar-holder').fullCalendar({
header: {
left: 'prev, next',
center: 'title',
right: 'month, agendaWeek, agendaDay, add_event'
},
lazyFetching: true,
timeFormat: {
// for agendaWeek and agendaDay
agenda: 'H:mm', // 5:00 - 6:30
// for all other views
'': 'H:mm' // 7p
},
eventSources: [
{
url: Routing.generate('fullcalendar_loader'),
type: 'POST',
// A way to add custom filters to your event listeners
data: {
},
error: function () {
//alert('There was an error while fetching Google Calendar!');
}
}
],
monthNames: ['Styczeń', 'Luty', 'Marzec', 'Kwiecień', 'Maj', 'Czerwiec', 'Lipiec', 'Sierpień', 'Wrzesień', 'Październik', 'Listopad', 'Grudzień'],
monthNamesShort: ['Sty', 'Luty', 'Marz', 'Kwie', 'Maj', 'Czer', 'Lip', 'Sier', 'Wrze', 'Paź', 'Lis', 'Gru'],
dayNames: ['Niedziela', 'Poniedziałek', 'Wtorek', 'Środa', 'Czwartek', 'Piątek', 'Sobota'],
dayNamesShort: ['Niedziela', 'Poniedziałek', 'Wtorek', 'Środa', 'Czwartek', 'Piątek', 'Sobota'],
buttonText: {
month: 'Miesiąc',
week: 'Tydzień',
day: 'Dzień'
},
eventLimit: true,
views: {
agenda: {
eventLimit: 3
}
},
});
});

So, I never heard of the plugin, I googled for the documentations, I opened the documentation and this was the first page I found that resembled your problem: https://fullcalendar.io/docs/display/eventLimit/
You need to add an event limit to your options that limit the amount of events on a day. Like so:
$('#calendar').fullCalendar({
eventLimit: true, // for all non-agenda views
views: {
agenda: {
eventLimit: 6 // adjust to 6 only for agendaWeek/agendaDay
}
}
});
If this does not solve your problem, please post the javascript code you are using. If this did solve your problem, please read the docs of this plugin before asking questions about it here.
