Topic: Node js calendar issues
Expected behavior
Open calendar window like the basic example, in a modal, and manage events insertion, update and delete.
Actual behavior
When I open the modal I can see correctrly loaded calendar with some basic events inserted via javascript exactly like the basic example. But when I try to insert a new one or update/delete an old event nothing appens. If I go to inspect browser console I can see a lot of errors like above code:

As you can see there are a lot of errors, first two are generated immediatly after the calendar is initializated. Any ideas? Thank you.

Can you provide a snippet that replicate this behavior?

I was able to notice when creating the snippet that it is probably an import problem, since it seems to work in the snippet. Consider that in my code I use separate javascript and the js code to insert events into the calendar is a module that first initializes the modal and onclick of the button, loads the events in the calendar and shows the modal with .show() I use this code to import the plugin and modal management, but in my environment of Electron-vite it is not the correct way to import my package...
// IMPORTING MDB KIT ES JS PACKAGE import { Modal, initMDB } from '../../../../node_modules/mdb-ui-kit/js/mdb.es.min.js'; initMDB({ Modal });
// IMPORTING MDB CALENDAR JS PACKAGE import * as mdb from '../../../../node_modules/mdb-ui-kit/js/mdb.umd.min.js'; // lib const Calendar = require('../../../node_modules/mdb-calendar/js/calendar.min.js');

We do not recommend using plugins with es modules.
If you want to o this anyway you have to tweak import syntax so modal and other components needed for Calendar will be imported as part of mdb
object e.g. mdb.Modal
.

Ok now I'm using it as common js and it works normally. But now I have another problem: I need to use the calendar inside a Modal. I can create the instance and load it with events, but when I click on the calendar to insert a new event or to update an existing one I receive those errors:
chart.es.min.js:15020 Uncaught TypeError: instance.update is not a function at chart.es.min.js:15020:18 at Array.forEach () at chart.es.min.js:15015:63 at handler (chart.es.min.js:13559:15) at Object.trigger (mdb.es.min.js:1007:16) at transitionComplete (mdb.es.min.js:21806:20) at execute (mdb.es.min.js:747:51) at executeAfterTransition (mdb.es.min.js:751:5) at Modal2._queueCallback (mdb.es.min.js:1143:5) at Modal2._showElement (mdb.es.min.js:21810:10)
and
mdb.umd.min.js:20 Uncaught RangeError: Maximum call stack size exceeded. at ne._handleFocusin (mdb.umd.min.js:20:23286) at HTMLDocument. (mdb.umd.min.js:20:22900) at HTMLDocument.i (mdb.umd.min.js:20:11325) at FocusTrap._handleFocusin (mdb.es.min.js:1721:19) at HTMLDocument. (mdb.es.min.js:1698:64) at HTMLDocument.handler (mdb.es.min.js:856:16) at ne._handleFocusin (mdb.umd.min.js:20:23286) at HTMLDocument.

I think the problem is precisely the use of the modal, somehow I find problems with excessive references or other things like that...
Thank you for the answer!

Can you provide the code (HTML and JS) that leads to this error? I'm unable to troubleshoot the issue based solely on the error message.
Verlino pro premium priority commented 1 months ago
Of course! I created a snippet for better comprension:

If you do UMD import:
import * as mdb from 'js/mdb.umd.min.js';
remove ES import and init:import { Modal, initMDB } from 'js/mdb.es.min.js'; initMDB({ Modal });
Plugins and main MDB package should be imported in the separate tags.
Add
window.mdb = mdb
where you import mdb package and addwindow.Calendar = Calendar
where you import calendar.Remove
data-mdb-button-init
attribute - it is not needed for regular buttons
After doing all this steps let me know if you still get this problem.
