I’m trying to open a modal window using bootstrap 5 (not the library React-Bootstrap) when cliking a Day in the FullCalendar Component in React.

I tried accesing through the modal using $ of JQuery but I get this error message "$ is not a function". I try importing the JQuery library before the bootstrap one, adding the "import $ from Jquery" line and nothing works.
I also have this implementation but it doesn’t work so I don’t know what I’m missing.

const CalendarContainerPage = () => {const modalRef = useRef(null);

   const [showModal, setShowModal] = useState(false);

   const select = (info) => {
      alert('selected ' + info.start + ' to ' + info.end);
   }

   console.log(showModal)
    const handleDayClick = () => {
      setShowModal(true);
      
    };
  
    const handleCloseModal = () => {
      setShowModal(false);
    };

    useEffect(() => {
      if(showModal){
        modalRef..toggle()
      }

    },[showModal])

   
  const randomColor= "#"+((1<<24)*Math.random()|0).toString(16) + "";

 
  const eventObject = [
              { // this object will be "parsed" into an Event Object
                groupId: 'blueEvents',
                title: 'Congress', // a property!
                start: '2023-06-21',
                end:'2023-06-22',
                startRecur: '2023-06-18T09:00:00',
                endRecur: '2023-06-29T18:00:00',
                startTime: '12:30:00', // a property!
                endTime: '13:30:00', // a property! ** see important note below about 'end' **
                daysOfWeek: [ '1','2' ],
                display: 'block',
                color : randomColor,
              }
            ]

    console.log(eventObject);

   const eventClick = (info) => {
      alert('Event: ' + info.event.title)
   }
 return(
    <div className='calendarBoard'>
     <FullCalendar
        plugins={[ dayGridPlugin, interactionPlugin ]}
       locale = {esLocale}
        initialView="dayGridMonth"
        height='100%'
        selectable={true}
      select = { handleDayClick}
      events = {eventObject}
      eventClick={eventClick}
      handleWindowResize={true}
      />


    {showModal && (<div className="modal " ref={modalRef} id="ModalDay" tabindex="-1" aria-labelledby="ModalDay" aria-hidden="true" >
        <div className="modal-dialog">
          <div className="modal-content">
            <div className="modal-header">
              <h5 className="modal-title" id="exampleModalLabel"> "text"</h5>
              <button type="button" className="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
            </div>
            <div className="modal-body px-4">
              Modal
            </div>
            <div className="modal-footer">
              <button type="button" className="btn btn-secondary" data-bs-dismiss="modal" onClick={handleCloseModal}>Cerrar</button>
              <button type="button" className="btn btn-primary">Guardar Cambios</button>
            </div>
          </div>
        </div>
      </div>)}
    
 </div>
 )
}

export default CalendarContainerPage

I also tried using useRef but I’m not sure if I’m using it correctly. (I’m new with React)

Just in case someone else has the same issue, I post here the solution I found:

import './calendarContainerPage.css'
import FullCalendar from '@fullcalendar/react' // must go before plugins
import interactionPlugin from '@fullcalendar/interaction'; // for selectable
import dayGridPlugin from '@fullcalendar/daygrid' // a plugin!
import esLocale from '@fullcalendar/core/locales/es';
import { useEffect, useState, useRef } from 'react';
import bootstrap from 'bootstrap/dist/js/bootstrap.min.js';



const CalendarContainerPage = () => {
  const [myModal, setMyModal] = useState(null);
  const [selectedInfoDay, setSelectedInfoDay] = useState({start:"", end: ""});

    const handleDayClick = (info) => {
   setSelectedInfoDay(info)
       myModal.show()

    };
  
    
  const randomColor= "#"+((1<<24)*Math.random()|0).toString(16) + "";

 
  const eventObject = [
              { // this object will be "parsed" into an Event Object
                groupId: 'blueEvents',
                title: 'Congress', // a property!
                start: '2023-06-21',
                end:'2023-06-22',
                startRecur: '2023-06-18T09:00:00',
                endRecur: '2023-06-29T18:00:00',
                startTime: '12:30:00', // a property!
                endTime: '13:30:00', // a property! ** see important note below about 'end' **
                daysOfWeek: [ '1','2' ],
                display: 'block',
                color : randomColor,
              }
            ]

    console.log(eventObject);

   const eventClick = (info) => {
      alert('Event: ' + info.event.title)
   }

   useEffect(() => {
    setMyModal(new bootstrap.Modal(document.getElementById('dayModal'), {
      keyboard: false
    }))
  }, []);
 return(
 
    <div className='calendarBoard'>
     <FullCalendar
        plugins={[ dayGridPlugin, interactionPlugin ]}
       locale = {esLocale}
        initialView="dayGridMonth"
        height='100%'
        selectable={true}
      select = { handleDayClick}
      events = {eventObject}
      eventClick={eventClick}
      handleWindowResize={true}
      />



{/* <!-- Modal --> */}
<div className="modal fade" id="dayModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
  <div className="modal-dialog">
    <div className="modal-content">
      <div className="modal-header">
        <h5 className="modal-title" id="exampleModalLabel">Modal title</h5>
        <button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
      </div>
      <div className="modal-body">
       {'selected ' + selectedInfoDay.start + ' to ' + selectedInfoDay.end}
      </div>
      <div className="modal-footer">
        <button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
        <button type="button" class="btn btn-primary">Save changes</button>
      </div>
    </div>
  </div>
</div>
</div>
 )
}

export default CalendarContainerPage

Basically I pick the Modal window using the boostrap.Modal function inside a useEffect to be sure to work with the modal after it is completly loaded:

 useEffect(() => {
    setMyModal(new bootstrap.Modal(document.getElementById('dayModal'), {
      keyboard: false
    }))
  }, []);

And call the click Handler of the day:

const handleDayClick = (info) => {
   setSelectedInfoDay(info)
       myModal.show()

    };

I found this solution using the bootstrap 5 documentation: [https://getbootstrap.com/docs/5.0/components/modal/#methods]

(Edit)

Have you imported the necessary dependencies ?
Let’s check the following requirements:

Install Bootstrap and its dependencies:

npm install bootstrap@^5.0.0
npm install react-bootstrap bootstrap fullcalendar

Import the necessary components and dependencies in your file:

import React, { useState } from 'react';
import FullCalendar from '@fullcalendar/react';
import dayGridPlugin from '@fullcalendar/daygrid';
import bootstrapPlugin from '@fullcalendar/bootstrap';
import { Modal, Button } from 'react-bootstrap';
import 'bootstrap/dist/css/bootstrap.min.css';
import '@fullcalendar/core/main.css';
import '@fullcalendar/daygrid/main.css';
import '@fullcalendar/bootstrap/main.css';

Import the Bootstrap CSS in your project’s main file (index.js or App.js):

import 'bootstrap/dist/css/bootstrap.min.css';
import '@fullcalendar/core/main.css';
import '@fullcalendar/daygrid/main.css';
import '@fullcalendar/bootstrap/main.css';

Modified code:

const CalendarContainerPage = () => {
  const [showModal, setShowModal] = useState(false);

  const handleDayClick = () => {
    setShowModal(true);
  };

  const handleCloseModal = () => {
    setShowModal(false);
  };

  return (
    <div className="calendarBoard">
      <FullCalendar
        plugins={[dayGridPlugin, bootstrapPlugin]}
        initialView="dayGridMonth"
        height="100%"
        selectable={true}
        select={handleDayClick}
      />

      <Modal show={showModal} onHide={handleCloseModal} aria-labelledby="modal-title">
        <Modal.Header closeButton>
          <Modal.Title id="modal-title">Modal Title</Modal.Title>
        </Modal.Header>
        <Modal.Body>Modal Body</Modal.Body>
        <Modal.Footer>
          <Button variant="secondary" onClick={handleCloseModal}>
            Close
          </Button>
          <Button variant="primary">Save Changes</Button>
        </Modal.Footer>
      </Modal>
    </div>
  );
};

export default CalendarContainerPage;
