This (I hope) is a basic question. I'm not seeing calendar events in fullcalendar, and I believe the issue is the date format I am attempting to use for start/end events. I am attempting to setup a basic calendar by loading JSON events. Here is my JSON output (trimmed to one event so as not to take up much room):
[{"id":"89","title":"A Title","start":"June 2nd 2015","end":"August 14th 2015"}]
My javascript looks like this:
$(document).ready(function() {
$('#calendar').fullCalendar({
editable: false,
events: "data.php"
});
});
Again, very basic. I know for certain that the issue for the events not appearing is due to the date format I am using, but I am not certain how to tell fullCalendar to use the MMMM Do YYYY format for start/end events with moment.js. Does anyone have advice on how this is accomplished?
EDIT:
Attempted to add something along these lines...but still no luck:
var start = moment(event.start).format("MMMM Do YYYY");
var end = moment(event.end).format("MMMM Do YYYY");
I'm not sure if this would be considered an answer or more of a workaround, but I'll post it as an answer anyway.
I ended up just converting the date format in the json output as Bruno had suggested in the above comment. Sort of wished I could have figured it out with the javascripting, but after hours of trying I could never get the events to display in the calendar.
I'll go ahead and post my php source for those curious (just showing the start date):
$start = $row['startdate'];
$start_obj = new \DateTime($start);
$events['start'] = $start_obj->format('Y-m-d');
I accomplished something similar by defining a function for the events, iterating through the data creating moment.js objects for the start field using my desired format. The docs have the basics for how to accomplish this.
EDIT: I copied the example from the docs and modified the start time using moment.js.
$('#calendar').fullCalendar({
events: function(start, end, timezone, callback) {
$.ajax({
url: 'myxmlfeed.php',
dataType: 'xml',
data: {
// our hypothetical feed requires UNIX timestamps
start: start.unix(),
end: end.unix()
},
success: function(doc) {
var events = [];
$(doc).find('event').each(function() {
events.push({
title: $(this).attr('title'),
start: moment($(this).attr('start'), 'MMMM Do YYYY') // will be parsed
});
});
callback(events);
}
});
}
});

I am working to add datepicker to fullcalendar so users can skip to a desired date. The issue I am having is getting the date variable from datepicker to work with calendar.gotoDate(). I am sure this is something simple, but I only know enough about javascript to struggle by.
I currently have a script using datepicker like so:
jQuery(function($) {
$('#datepicker').datepicker({
dateFormat: 'yy-mm-dd',
});
function get_datepicker() {
var date = $('#datepicker').datepicker('getDate');
return date;
};
});
After I call fullcalendar (which is working flawlessly) I am trying to add a listener for the date change.
document.getElementById('datepicker').addEventListener('change', function() {
get_datepicker();
calendar.gotoDate(date);
});
since fullcalendar has removed jquery, it makes it a bit tougher (for me at least) to implement other scripts like datepicker, which normally wouldn't make sense to load, but in Wordpress, it is already there...
You are never setting the date variable inside the change listener. Either of the following should work.
document.getElementById('datepicker').addEventListener('change', function() {
let date = get_datepicker();
calendar.gotoDate(date);
});
OR
document.getElementById('datepicker').addEventListener('change', function() {
calendar.gotoDate(get_datepicker());
});
I feel like this question is reasonably straightforward. I'm trying to dynamically change options on the Tempus Dominus Bootstrap Datetimepicker.
In particular, I'd like to change the options on one of my datepickers on change of another datepicker on the same page.
// Initialisation.
$(function () {
$("#datetimepicker_start").datetimepicker({
format: 'DD/MM/YYYY',
date: '{{ widget.value }}',
minDate: moment() // Today's date.
});
});
// Initialisation.
$(function () {
$("#datetimepicker_end").datetimepicker({
format: 'DD/MM/YYYY',
date: '{{ widget.value }}',
minDate: moment() // Today's date.
});
});
// Document ready, set up event listener:
$('#datetimepicker_start').on('change.datetimepicker', function() {
$("#datetimepicker_end").datetimepicker({
format: 'DD/MM/YYYY',
date: moment()
minDate: $('#datetimepicker_start').val() // Trying to limit the mininmum date of this picker
// to the be value of the first.
});
});
This is an edited example. I'm currently dynamically inserting the initial date picker instantiation with my template logic as it's part of a form that is loaded in by my web framework.
I can't seem to find a way to update these options on the fly. Explicitly what I'm trying to do is link the two date pickers so that the user can't pick an end date earlier than the start. I've also tried
$("#datetimepicker_end).minDate = $('#datetimepicker_start).val()
Or even just a moment() for the value I set in the above line. No change. Any point in the right direction would be great.
EDIT: SOLUTION:
$('#datetimepicker_start').on('change.datetimepicker', function() {
var new_min_date = $(this).datetimepicker('date');
$("#datetimepicker_end").datetimepicker('minDate', new_min_date);
});
BONUS QUESTION:
The above method does what I'm trying to achieve, however when setting a minimum date it doesn't allow the end date box to stay blank if it already was. Does anyone know how to achieve this?
i'm using fullcalendar in a web application i"m building.
i load my events with events function and ajax.
here is my code:
var ajaxData;
var eventsJsonArray;
var json_backgrundColor;
var json_iconstring;
//alert('Hello! 1!');
$(document).ready(function () {
$('#calendar').fullCalendar({
header: {
left: 'prev',
center: 'title',
right: 'next,month,agendaWeek,agendaDay'
},
//custom events function to be called every time the view changes
events: function (start, end, timezone, callback) {
var mStart = start.format('M')
var yStart = start.format('YYYY')
$.ajax({
url: '$getMonthDataUrl',
type: 'GET',
data: {
startDate: start.format(),
endDate: end.format()
},
error: function () {
alert('there was an error while fetching events!');
},
success: function (data) {
alert('nice!!');
ajaxData = data;
json_iconstring = ajaxData['iconString'];
json_backgrundColor = ajaxData['Calendar_cell_background_color'];
eventsJsonArray = ajaxData['all_Events_For_The_Month'];
callback(eventsJsonArray); //pass the event data to fullCalendar via the supplied callback function
}
});
},
fixedWeekCount: false,
showNonCurrentDates: false,
dayRender: function (date, cell, view) {
console.log(json_backgrundColor);//this brings eror because json_backgrundColor is undefined
var cellDate = date.format('D');
if (date.format('M') == view.start.format('M')) //cheacking is this day is part of the currrent month (and not prev/next month)
{
alert(cellDate);
cell.css('background-color', json_backgrundColor[cellDate]);//this brings eror because json_backgrundColor is undefined
}
},
})
});
when i load my events via ajax i'm also getting the information about which background color each cell should get. i can only get this info via the events ajax request.
the problem is that when the dayRender is running, i still don't have the background color data. (json_backgrundColor is undefined).
is there a way that dayRender will run after the events calendar will stop running? or any other code that will fix my problem.
many thanks!!
Your problem is that the "dayRender" callback runs after the view is changed (changing the date using prev/next counts as changing the view, for this purpose), but before the events for the new view have been downloaded and rendered. That's why your json_backgrundColor array is undefined.
Since you mentioned that the colour to be used depends on the exact nature of the events currently scheduled for that specific day, we need to find something that we can run after all the events, and this colour data, have been downloaded.
Inspecting the HTML, we can see that the table cells used to draw each day all have the CSS class "fc-day" applied. They also have a data-date property containing the day that they relate to. Finally, days that are disabled (outside the main month, due to you setting showNonCurrentDates:false) have an extra class of "fc-disabled-day" applied. We can use these pieces of information to identify the cells we want to change, without having to use the dayRender callback.
The eventAfterAllRender callback runs once when all the events have been rendered. Therefore this seems like a good place to alter the background colours of the cells:
eventAfterAllRender(function(view) {
//loop through each non-disabled day cell
$('.fc-day:not(.fc-disabled-day)').each(function(index, element) {
//set the background colour of the cell from the json_backgroundColor arrray, based on the day number taken from the cell's "data-date" attribute.
$(this).css('background-color', json_backgroundColor[moment($(this).data("date")).format("D")]);
});
}
Note that I have renamed json_backgrundColor to json_backgroundColor to correct the spelling error.
N.B. This is brittle in the sense that it relies on the class names that fullCalendar uses internally to represent the day cells. If fullCalendar decides to do this differently in a future release, it will break (whereas if we were able to use the fullCalendar API via the designated callbacks, they would likely maintain consistency despite internal changes, or at least document any change). But it's pretty key to the Month view, so realistically it's not likely to change any time soon - you would just have to remember to test it if you update your fullCalendar version.
if anyone still wondering you can use dateSet option like
datesSet: event => {
var from = moment(event.start).format('YYYY-MM-DD');
var to = moment(event.end).format('YYYY-MM-DD');
dateStatus = getEachDateStatus(from, to);
//{'2022-11-10' : 'fullbooked', '2022-11-09' : 'halfBooked'};
Object.keys(dateStatus).forEach(key => {
$('td[data-date="'+key+'"]').addClass(dateStatus[key]);
});
},
Instead of relying on dayRender, you should create background color events based on your ajax:
events = [
...
{ date: date
color: ...
rendering: 'background'
className: 'my-class'
}]
You can transform events using css any way you like, with or without the rendering: 'background' option.
So, in my site, I'm using full calendar for its intended purpose. Through a JSON call to a WebService, in my aspx code, I'm getting all the events for a given month from the database. Those are then fed to the calendar. That works quite nicely under Chrome, and the events display properly; unfortunately, under Firefox, (and others) I'm not so successful. If I display event using the most simple form possible, it works in FireFox just fine:
events: [
{
title: 'My Event',
start: '2016-05-01',
description: 'This is a cool event'
},
{
title: 'My Event',
start: '2016-05-02',
description: 'This is a cool event'
}
]
But if I use the code, I have to get the Events dynamically from the database and display them, and then it all fails (again it works on Chrome just fine):
events: $.map(data.d,function (item, i)
{
var event = new Object();
event.start = formatDate(item.StartDate);
event.end = formatDate(item.EndDate);
event.title = item.EventName;
return event;
}),
I managed to determine that neither item.StartDate nor its formatyee works, and the latter alerts 'Invalid date'. Following some further investigation after an unsuccessful attempt to format the date to 'YYYY-MM-DD', I managed to find this solution which apparently is the same as mine, and OP manages to fix their problem.
I can't seem to figure out how they managed to change the format to ISO8601.
It turned out I was converting the Date, before it even gets to the Javascript (when I was getting it from the Database) to a wrong format that even the JS had hard time fixing. For anyone else having problems with the Events on different browsers, just convert your start/end dates to be "yyyy-MM-dd HH:mm:ss" or "yyyy-MM-dd" if you're not using the time variable and it should all be just fine.
I got JSON with correct time but fullcalendar (?) shows my event 1 hour ahead. I tried timezone : local , ignoreTimezone but no success any help would be nice I'm desprate.
My timezone is UTC +08:00
My json is {"hmi_alldays":[{""order_employee_start":"2015-02-03T05:00:00","order_id":1791}
I had a similar issue. I don't know which version of fullcalendar you are using, but the latest version at this time (2.2.6) in combination with moment.js and the usage of timezone works completely fine for me:
var events_array = [
{
title: 'Test1',
start: moment('2015-02-03T05:00:00'),
end : moment('2015-02-03T12'),
tip: 'Test1'},
];
...
$('#calendar').fullCalendar({
events: events_array,
timezone : 'local',
eventRender: function(event, element) {
element.attr('title', event.tip);
}
});
See example here.
