jQuery modal not showing after submitting form

I am trying to show a message after a user clicks on a button to submit a form but my modal is not getting displayed. don't know why this is happening.
My html code:
<form method="POST" class="course-save-form">
{% csrf_token %}
<button class="small btn no-border dropdown-item save-course" type="button" data-url="{% url 'home:course-save' course.id %}"><i class="mr-1 m fas fa-bookmark"></i>Save</button>
</form>
my modal:
<div class="modal fade" id="modal-save-course">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="moda-body">
<div class="modal-header text-center">
<h5 class="modal-title col-12 text-center">Save Course
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</h5>
</div>
<h6 class="text-message"></h6>
</div>
<div class="modal-footer col-12">
<button type="button" class="btn btn-seconday" style="border-radius: 20px; width: 100%;">Close</button>
</div>
</div>
</div>
</div>
and my jQuery:
$(document).ready(function (e) {
$('.course-save-form').on("click", ".save-course", function (e) {
var btn = $(this)
e.preventDefault();
e.stopImmediatePropagation();
$.ajax({
type: "POST",
url: $(this).attr("data-url"),
dataType: 'json',
data: $(this).closest("form").serialize(),
success: function (data){
$('#modal-save-course').show();
$('#modal-save-course.modal-content.modal-body.text-message').html(data.message);
},
error: function(rs, e){
console.log(rs.responeText);
},
});
});
})
My button works but my modal is not getting displayed with the message.

Use $('#modal-save-course').modal('show');
Also, text wasn't displaying with .html , so use .text :
$('#modal-save-course .text-message').text(data.message);
$('#modal-save-course').modal('show');
See screenshot:

The confirm delete button on my modal isn't working

I have created a pop up modal for my delete button on a page. When you clicked on the delete button, a modal will pop up and ask you whether you really want to delete the item or not. There are two buttons on the modal, the first one is cancel and the other one is delete. Clicking on the cancel button will close the pop up but when i click on the delete button, nothing happens.
Here is the php code for the delete button:
echo "<a href='#myModal' class='btn btn-danger' data-toggle='modal'> Delete</a>";
Here is the modal code:
<div id="myModal" class="modal fade">
<div class="modal-dialog modal-confirm">
<div class="modal-content">
<div class="modal-header">
<div class="icon-box">
<i class="material-icons"></i>
</div>
<h4 class="modal-title">Are you sure?</h4>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<div class="modal-body">
<p>Do you really want to delete these records? This process cannot be undone.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-info" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-danger" id="confirm">Delete</button>
</div>
</div>
</div>
</div>

you have not given anything on click of the delete button and how you are expecting something? if you add data-dismiss="modal" for button it will close the popup. rest of the things u can handle it using javascript.
function Delete()
{
//Write your code for deleting
$.ajax({
type: "post",
datatype: "json",
async: false,
contenttype: "application/json",
url: "DeleteItem.php",
success: function (result) {
$('#myModal').modal('hide'); //for hiding popup
},
error: function(xhr, ajaxOptions, thrownError) {
//handle error
}
});
}
<div id="myModal" class="modal fade">
<div class="modal-dialog modal-confirm">
<div class="modal-content">
<div class="modal-header">
<div class="icon-box">
<i class="material-icons"></i>
</div>
<h4 class="modal-title">Are you sure?</h4>
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
</div>
<div class="modal-body">
<p>Do you really want to delete these records? This process cannot be undone.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-info" data-dismiss="modal">Cancel</button>
<button type="button" class="btn btn-danger" onclick="Delete()" id="confirm">Delete</button>
</div>
</div>
</div>

Pass values to bootstrap modal in jQuery success function

I have a Bootstrap modal inside a jQuery success function. I want to show
some value in the model.
My model:
<div class="modal fade" id="REQModal" role="dialog" data-backdrop="static" data-keyboard="false">
<div class="modal-dialog modal-sm">
<div class="modal-content">
<div class="modal-header btn-danger">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Error Message</h4>
</div>
<div class="modal-body">
<div id="num"></div>
<p>Error has occured!.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
My function:
$.ajax({
url: $('#addRequest').val(),
type: "POST",
data: { Request: Request },
dataType: "json",
success: function (refNo) { // refNo comes here.
$("#num").val(refNo);
$("#REQModal").modal('show'); // modal popup's but refNo doesn't show.
}
});

try:
$("#num").html(refNo);
instead of
$("#num").val(refNo);

Try this
$("#num").html(refNo);

ajax
function get(u_id,e_id)
{
$.ajax({
url: "<?echo base_url()?>events/xyz",
type: 'post', // HTTP METHOD
data:
{u_id:u_id,e_id:e_id },
success: function(data)
{
//alert(data);
if(data==1)
{
// add your code pls
}
else if(data==2)
{
alert("hai");
}
else if(data==3)
{
alert("hello");
}
}
});
}
my function in php controller
public function xyz()
{
$u_id=$this->input->post('u_id');
$e_id=$this->input->post('e_id');
$temp=$this->session->userdata('user');
$g=$this->xm->is_going($u_id,$e_id);
$g1=$this->xm->is_going1($u_id,$e_id);
if($temp=="")
{
$d=1;
echo $d;
}
else if($g==$u_id)
{
$d=2;
echo $d;
}
else if($g1==$u_id)
{
$d=3;
echo $d;
$this->xm->event_updation($e_id,$u_id);
}
else
{
$data=array('event_id'=>$e_id,'ev_going'=>$u_id);
$this->xm->eventgoing($data);
}
}

Just change your JavaScript a bit as shown in this code:
function get(u_id,e_id)
{
$.ajax({
url: "<?echo base_url()?>events/xyz",
type: 'post', // HTTP METHOD
data:
{u_id:u_id,e_id:e_id },
success: function(data)
{
//alert(data);
if(data==1)
{
jQuery("#exmpModal").modal('show');
}
else{
jQuery("#exmpModal").modal('hide');
}
}
});
}
