fullCalendar renderEvent not sticking - javascript

I'm trying to insert an event to my fullcalendar and let it be there when i refresh the page but it's disappeared for some reason.
<script>
$(document).ready(function() {
// page is now ready, initialize the calendar...
$('#calendar').fullCalendar({
header: {
left: 'prev,next today',
center: 'title',
right: 'month,basicWeek,basicDay'
},
selectable: true,
selectHelper: true,
select: function(start, end) {
var title = prompt('Event Title:');
var eventData;
if (title) {
eventData = {
title: title,
start: start,
end: end
};
$('#calendar').fullCalendar('renderEvent', eventData, true);
}
$('#calendar').fullCalendar('unselect');
},
})
});
</script>
I have try to change the code as well so it look samthing like this
if (title)
{
calendar.fullCalendar('renderEvent',
{
title: title,
start: start,
end: end,
allDay: allDay },
true
);
}
calendar.fullCalendar('unselect');
},
but i just got nothing on the page like i missing something

The data disappears when you refresh the page because you haven't saved the new event anywhere, nor do you have any functions to retrieve the previously-saved events. The new event exists solely within browser document. As soon as you leave the page, the document's data is discarded.
You need to save the data somewhere—client-side or server-side—then you need to retrieve that saved data each time the page loads. Traditionally programmers store data server-side, usually in databases. Client-side storage stores data in the browser and can be useful if users only need to access their own data but comes with many limitations (e.g., your work computer and home computer will have different saved data).

Can you store js code on the fly in a variable and have js read it?

I'm not sure if what I'm trying to do is the correct/valid approach to what I'm trying to accomplish; essentially, I'm retrieving data from a db via an ajax call, I want this data to populate a js library where the layout is something like
data[
item{
name: 'name',
start_date: date,
end_date: date
},
item{
name: 'name',
start_date: date,
end_date: date
},
]
is there any way I can populate the code inside 'data' on the fly?
I was thinking with a loop to populate a variable which would hold the data and placing it like so
//this is hard coded, but the idea is that a loop would populate this with the necessary information
let items = "
item{
name: 'name',
start_date: date,
end_date: date
},
item{
name: 'name',
start_date: date,
end_date: date
}";
data[
items
]
Would this be a valid approach?
thanks in advance!
UPDATE:
For clarification, this what I have
$('#calendar').fullCalendar({
defaultDate: today,
eventLimit: true,
events: [
{
title: 'Some event',
start: '2022-08-31',
end: '2022-08-31'
},
{
title: 'Some event',
start: '2022-08-31',
end: '2022-08-31'
}
]
});
What im trying to achieve is something like this
let allEvents = "
{
title: 'Some event',
start: '2022-08-31',
end: '2022-08-31'
},
{
title: 'Some event',
start: '2022-08-31',
end: '2022-08-31'
}";
$('#calendar').fullCalendar({
defaultDate: today,
eventLimit: true,
events: [
allEvents;
]
});
Would this be possible?
So, closing this question, thanks to #DaveNewton for the insight, it really clarified what I was supposed to do; I apologize for the confusion, my thought process essentially revolved around 'echoing' or 'printing' code in php.
my approach was:
$.ajax({
type: "GET",
url: filethathandlesrequest.php,
data: {
data_to_be_sent: 'data',
},
success: function(response) {
response = JSON.parse(response);
eventsGotten = response.return_result;
//this is where I create the object
let eventsToDisplay = [];
for (let index = 0; index < eventsGotten.length; index++) {
const element = eventsGotten[index];
let singleEvent = {title: element.description, start: element.start_date, end: element.end_date};
eventsToDisplay.push(singleEvent);
}
if (response.return_code === 0) {
if ($('#calendar').exists()) {
loadScript(plugin_path + 'fullcalendar/fullcalendar.min.js', function() {
$('#calendar').fullCalendar({
defaultDate: today,
//editable: true,
eventLimit: true,
events: eventsToDisplay // <-- this is where I use it; and it works!
});
});
}
} else { //you can ignore this, this is just to not display anything if my ajax request fails
if ($('#calendar').exists()) {
loadScript(plugin_path + 'fullcalendar/fullcalendar.min.js', function () {
$('#calendar').fullCalendar({
defaultDate: today,
//editable: true,
eventLimit: true,
events: []
});
});
}
}
});
It seems you are asking if you can import data from a database and populate a JSON array in Javascript with it. The answer would be yes. In fact, I do this routinely to create Javascript front ends that can be quickly rendered and only talk to the database when necessary so you're not waiting on it. You can use Jquery ajax calls to retrieve and write data. I like to have local variables with JSON formatted data which I use to run the app. The app can quickly read and write changes to these JSON arrays. Keep in mind if the page is reloaded or fails all the data to that point will be lost and the user will have to start over so you need to store data to the database at strategic intervals. You can also use HTML localStorage to store data in the browser itself. I've found this an efficient way to build single-page Javascript apps without resorting to React or some of the other frameworks. It's not as efficient though, but easier to code and maintain.
The approach I would take is to define a particular DOM element as a parent / container for the DOM elements which will represent each item. Iterate over the items array in your ajax response, and create DOM elements with jquery for each item. Something along the lines of $('<div>${currentItem.name}>/div>').appendTo(containerDiv);

Calling function whenever full calendar view changes in Angular 8

I am using full calendar in my angular 8 app. Everything is working fine, but I want to call a function whenever the currentView of calendar changes. that is, I want to call a function/event whenever I change its view from month to week, or week to days.
For clarity, I want to detect view template changes (not date range changes). And by detecting it I want to highlight the button of respective current view.
This is my html code.
<p-fullCalendar #fc [events]="allEvents" [options]="options"></p-fullCalendar>
This is my .ts code
this.options = {
plugins: [dayGridPlugin, timeGridPlugin, interactionPlugin],
defaultDate: moment().toDate(),
themeSystem: 'yeti',
header: {
left: 'prev,next',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay'
}, dateClick: (e) => {
this.dateClicked(e);
}, eventClick: (e) => {
this.eventClicked(e);
},
}
In fullCalendar 4 you can use the viewSkeletonRender callback - this runs whenever a new view template is loaded.
viewSkeletonRender: function(info)
{
console.log(info); //replace with whatever code you need.
}

Events are duplicated when switching months in Fullcalendar v4

I'm using Fullcalendar v4 like this. Events are loaded correctly, but when I manually add a new one (it is also saved to SQL database via ajax call), then I change month and return back, this event is rendered twice. I'm not sure what cause this, because when I change months again, event is still doubled only, not trippled.
I've tried set lazyLoading or cache to false and also, for example, remove all events before rendering with $('.fc-event').remove(); but it did not help.
var calendar = new FullCalendar.Calendar(document.getElementById('calendar'), {
defaultView: 'resourceTimeline30',
views: {
resourceTimeline30: {
type: 'resourceTimeline',
duration: { days: 30 }
}
},
editable: false,
selectable: true,
resources: [ ... ],
events: 'https://www.example.com/?fullcalendar=load',
/*
// did not help
lazyLoading: true,
events: {
url: 'https://www.example.com/?fullcalendar=load',
cache: false,
extraParams: function() {
return {
cachebuster: new Date().valueOf()
};
}
}
*/
});
calendar.render();
So, if anybody needs it, according comments above, the working solution is:
Replace:
events: 'https://www.example.com/?fullcalendar=load',
With
eventSources: [{
'id': 1,
'url': 'https://www.example.com/?fullcalendar=load'
}],
And use that ID as second parameter in addEvent()
calendar.addEvent(event, 1);

Rails webpack js and refresh on ajax

I have a calendar module rendered in webpack js - app/javascript/packs/application.js
document.addEventListener('DOMContentLoaded', function() {
var calendarEl = document.getElementById('calendar');
var calendar = new Calendar(calendarEl, {
plugins: [ interactionPlugin, dayGridPlugin, timeGridPlugin, listPlugin, momentPlugin ],
header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
},
defaultDate: '2018-01-12',
navLinks: true, // can click day/week names to navigate views
editable: true,
eventLimit: true, // allow "more" link when too many events
selectable: true,
events: '/events.json',
select: function(info) {
$.getScript('/events/new', function(){
$('#event_date_range').val(moment(info.start).format('YYYY-MM-DD HH:mm') + ' - ' + moment(info.end).format('YYYY-MM-DD HH:mm'));
$('#start_date').val(moment(info.start).format('YYYY-MM-DD HH:mm'));
$('#end_date').val(moment(info.end).format('YYYY-MM-DD HH:mm'));
});
}
});
calendar.render();
});
I have a create action and would like to re-render the calendar on successful callback - create.js.erb. How can I do this?
Note: I'm assuming you're using Rails 6. I'm also assuming you added format.js to your create action.
Forget about create.js.erb, you won't need it here.
Also, you shouldn't put your code in app/javascript/packs/application.js.
The comments in that file read:
This file is automatically compiled by Webpack, along with any other files present in this directory. You're encouraged to place your actual application logic in a relevant structure within app/javascript and only use these pack files to reference that code so it'll be compiled.
This is how you would structure it:
Create the folder app/javascript/calendar and inside that folder, create a file index.js with your code in it:
// import your calendar object (put it in a file calendar.js in the same folder)
import Calendar from './calendar';
document.addEventListener('DOMContentLoaded', function() {
var calendarEl = document.getElementById('calendar');
var calendar = new Calendar(calendarEl, {
plugins: [ interactionPlugin, dayGridPlugin, timeGridPlugin, listPlugin, momentPlugin ],
header: {
left: 'prev,next today',
center: 'title',
right: 'dayGridMonth,timeGridWeek,timeGridDay,listWeek'
},
defaultDate: '2018-01-12',
navLinks: true, // can click day/week names to navigate views
editable: true,
eventLimit: true, // allow "more" link when too many events
selectable: true,
events: '/events.json',
select: function(info) {
$.getScript('/events/new', function(){
$('#event_date_range').val(moment(info.start).format('YYYY-MM-DD HH:mm') + ' - ' + moment(info.end).format('YYYY-MM-DD HH:mm'));
$('#start_date').val(moment(info.start).format('YYYY-MM-DD HH:mm'));
$('#end_date').val(moment(info.end).format('YYYY-MM-DD HH:mm'));
});
}
});
// actually, you want to put that addEventListener on your form
// more on 'ajax:success': https://guides.rubyonrails.org/working_with_javascript_in_rails.html#rails-ujs-event-handlers
document.body.addEventListener('ajax:success', function(event) {
var detail = event.detail;
var data = detail[0], status = detail[1], xhr = detail[2];
if (status === 'OK') { // upon success
// do something
// re-render the calendar
calendar.render();
}
})
calendar.render();
});
Note the part I added:
// actually, you want to put that addEventListener on your form
// more on 'ajax:success': https://guides.rubyonrails.org/working_with_javascript_in_rails.html#rails-ujs-event-handlers
document.body.addEventListener('ajax:success', function(event) {
var detail = event.detail;
var data = detail[0], status = detail[1], xhr = detail[2];
if (status === 'OK') { // upon success
// do something
// re-render the calendar
calendar.render();
}
})
Next, you create your pack file app/javascript/packs/calendar.js and inside it, you just reference your module like so:
// importing calendar module
import '../calendar';
Now Webpack will compile your file automatically.
What's left is using the helper javascript_pack_tag that adds a script tag that references the named pack file compiled by webpack : <%= javascript_pack_tag 'calendar' %>. Add this at the bottom of your view file (for example index.html.erb).
Hope this helps.
You can use addEvent method to add the new event to the calendar
https://fullcalendar.io/docs/event-object
https://fullcalendar.io/docs/Calendar-addEvent-demo
in the success callback of create action
$.ajax({
...
}).done(function (response) {
// Add event to calendar
calendar.addEvent({
title: response.title,
start: response.start_date,
end: response.end_date,
allDay: response.all_day
})
})

Is it possible to email listWeek

Is it possible to send output to email instead of
<div id="fullCalendar" ></div>
after a full night, surfing the web, i cant find the solution, i'm no jquery programmer, so i realy hope some one can point me in the right direction
$(function() {
'use strict';
$('#fullCalendar').fullCalendar({
locale: 'nl',
defaultView: 'listWeek',
events: 'admin_app/kalender_load.php',
eventColor: '',
selectable:true,
selectHelper:true
});
});
$.post("email.php", { data : $("div#fullCalendar").html() }, function(result){
/* handle results */
});
I aspect to send the events from upcomming week true email,
but all i get is an empty mail
fullCalendar renders its content asynchronously - both the view and the events are rendered in separate asynchronous processes. You are trying to capture the content before it has been drawn (and in the case of the events, before the data has even been downloaded from your server).
You can use the viewRender callback to cause your code to wait until the calendar has been rendered.
Or if you need to include event data (which I guess you might) then you should use eventAfterAllRender instead, which waits until your events have been downloaded and drawn as well (this always occurs after the view has been rendered):
$(function() {
'use strict';
$('#fullCalendar').fullCalendar({
locale: 'nl',
defaultView: 'listWeek',
events: 'admin_app/kalender_load.php',
eventColor: '',
selectable: true,
selectHelper: true,
eventAfterAllRender: function(view) {
console.log($("div#fullCalendar").html())
$.post("email.php", {
data: $("div#fullCalendar").html()
}, function(result) {
/* handle results */
});
}
});
});
