Fullcalendar modal not showing jQuery

Question

I have a full calender applicaiton. When I added code for showing a modal

function InitalizeCalendar() {
        try {

            var calenderEl = document.getElementById("calendar");
            if (calenderEl != null) {
                var calendar = new FullCalendar.Calendar(calenderEl, {
                    initialView: "dayGridMonth",
                    headerToolBar: {
                        left: 'prev,next,today',
                        center: 'title',
                        right: 'dayGridMonth,timeGridWeek,timeGridDay'
                    },
                    selectable: true,
                    editable: false,
                    select: function (event) {
                        onShowModal(event, null);
                    }
                });
                calendar.render();
            }

        }
        catch (e) {
            alert(e)
        }
    }

    function onShowModal(obj, isEventDetail) {
        $("#myModal").modal("show");
    }

nothing happends. In chrome, when i add a breakpoint to the function it gets triggered.

Anyone here knows what may cause this? I dont get much help to solving the problem in chrome console.

When clicking on the calendar, the modal doesn't show up, right?

Have you tried testing opening your modal with a button click.

I think the problem is related to your modal.

I simulated your code and added the modal. It works fine.

You can try like this:

function InitalizeCalendar() {
        try {
            var calenderEl = document.getElementById("calendar");
            if (calenderEl != null) {
                var calendar = new FullCalendar.Calendar(calenderEl, {
                    initialView: "dayGridMonth",
                    headerToolBar: {
                        left: 'prev,next,today',
                        center: 'title',
                        right: 'dayGridMonth,timeGridWeek,timeGridDay'
                    },
                    selectable: true,
                    editable: false,
                    select: function (event) {
                        onShowModal(event, null);

                    }
                });
                calendar.render();
            }

        }
        catch (e) {
            alert(e)
        }
    }

    InitalizeCalendar();

    function onShowModal(obj, isEventDetail) {
        $("#exampleModal").modal("show");
    }
