How to show modal after Ajax success?

After the article is successfully added, the modal showing the message should appear, but I'm just getting errors. So far this is my code:
Modal:
<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">Awesome!</h4>
</div>
<div class="modal-body">
<p class="text-center">Your booking has been confirmed. Check your email for detials.</p>
</div>
<div class="modal-footer">
<button class="btn btn-success btn-block" data-dismiss="modal">OK</button>
</div>
</div>
</div>
</div>
Ajax:
<script type="text/javascript">
$('#form').on('submit', function (e) {
e.preventDefault();
var f = CKEDITOR.instances.text.getData();
var text = String(f);
var n=text.length;
var title = $('#title').val();
var docu_id = $('#docu_id').val();
var hidden_snippet = $('#hidden_snippet').val();
if (n!=0) {
$.ajax({
type: 'POST',
url: '/knowmore/index.php/ask_controller/book_add',
data: {text:text,title: title,hidden_snippet: hidden_snippet,docu_id:docu_id},
success: function (data)
{
$("#myModal").modal('show')
location.replace('/knowmore/index.php/index_controller/documentation/'+docu_id+'');
}
});
} else { alert('Enter contents of the Article!'); }
});
</script>
I used $("#myModal").modal('show') to show it but all I'm getting is an error saying modal is not a function.

If you all you need is to open a bootstrap modal, then just use
$('#myModal').modal();

It's because jQuery doesn't know any function named modal by default. If you want to show the modal you can just use show() function.
Change following
success: function (data) {
$("#myModal").modal('show')
location.replace('/knowmore/index.php/index_controller/documentation/' + docu_id + '');
}
into
success: function (data) {
$("#myModal").show();
location.replace('/knowmore/index.php/index_controller/documentation/' + docu_id + '');
}

Write down the following code.
success: function(msg)
{
$("#myModel").modal("show");
}

Javascript methods stop working after writing another method in the same script tag

I have written a code on codeigniter framework for approve and disapprove leave of employees. The approval and disapproval worked fine before. But after I write another methods in the same script tag for showing the leave details of the employees the approval and disapproval stopped working.
What can I change in order to make the two buttons work. The two buttons are also inside the modal.
javascript
<script>
$(function(){
var BASE_URL = "http://localhost/employeemgt/index.php/";
$('#pedingLeaveRequest').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget);
var current_leave_id = button.data('id');
var modal = $(this);
modal.find('input[name="current_leave_id"]').val(current_leave_id);
});
//approve button
$('#approvebtn').click(function(){
var id = $('input[name="current_leave_id"]').val();
$.post(BASE_URL + 'admin/AdminDashboardController/approveLeave',
{'id': id},
function(result){
console.log(result);
if(result.error){
alert('try again');
}else{
alert('Leave has been approved!');
}
});
});
//disapprove button
$('#declinebtn').click(function(){
var id = $('input[name="current_leave_id"]').val();
$.post(BASE_URL + 'admin/AdminDashboardController/disapproveLeave',
{'id': id},
function(result){
console.log(result);
if(result.error){
alert('try again');
}else{
alert('Leave has been disapproved!');
}
});
});
});
//show leave details on modal
$("#showleave").on('click','button',function(event){
var BASE_URL = "http://localhost/employeemgt/index.php/";
var leave_id = $(this).val();
$.ajax({
type: 'POST',
dataType: "JSON",
data:{leave_id:leave_id},
url: BASE_URL + 'admin/AdminDashboardController/viewRequest',
success:function(data){
console.log(data);
$('#leave_details').html(data);
$('#pendingLeaveRequest').modal('show');
},
error:function(error){
alert(error);
}});
});
</script>
view:
<div id="showleave">
<h4 class="mb-4">Pending Requests</h4>
<?php
foreach ($leave as $row) {
if($row->status != "1")
{
echo '
<ul class="list-unstyled">
<li class="media border-bottom border-top py-3">
<img class="mr-3" src="http://via.placeholder.com/64x64" alt="Generic placeholder image">
<div class="media-body">
<h5 class="mt-0 mb-1">'.$row->user_name.'</h5>
<p class="mb-0 mt-0">'.$row->leave_start.' to '.$row->leave_end.'</p>
<p class="mt-0">'.$row->leave_type.'</p>
<button type="button" class="detailButton" href="<?php echo $id; ?>" data-id="'.$row->id.'" data-name="'.$row->user_name.'" data-toggle="modal" value="'.$row->id.'">View Request</button>
</div>
</li>
</ul>
';
}
}
?>
</div>
modal
<!-- Modal -->
<div class="modal fade" id="pendingLeaveRequest" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Leave Request</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body" id="leave_details" >
<p> </p>
</div>
<div class="modal-footer">
<input type="hidden" name="current_leave_id" id="current_leave_id" value="" />
<button type="button" id="declinebtn" class="btn btn-secondary" data-dismiss="modal">Decline</button>
<button type="button" id="approvebtn" class="btn btn-primary">Approve</button>
</div>
</div>
</div>
</div>

As you are replacing the $('#pendingLeaveRequest #leave_details').html(data); with new data so the button don't work.. Try to replace it with new id....
//show leave details on modal
//$("#showleave").on('click',function(){
$('.detailButton').on('click', function(){
var BASE_URL = "http://localhost/employeemgt/index.php/";
var leave_id = $(this).val();
$.ajax({
type: 'POST',
dataType: "JSON",
data:{leave_id:leave_id},
url: BASE_URL + 'admin/AdminDashboardController/viewRequest',
success:function(data){
console.log(data);
$('#leave_details p').html(data);
$('#pendingLeaveRequest').modal('show');
},
error:function(error){
alert(error);
}});
});
let me know if it is working..

Bootstrap Modal in Django application with Ajax

dynamic ajax bootstrap modalbox not work in action

I have this code for showing dynamic data in a bootstrap modal box using $.ajax and json.
JS:
$(function() {
$('.push').click(function() {
var id = $(this).attr('id');
$.ajax({
type: 'post',
url: '<?PHP echo SITE;?>controller/booksdetails.php', // in here you should put your query
dataType: "json",
data = {
'bookid': id,
'csrf_token': <?php echo $token; ?>
},
success: function(r) {
// now you can show output in your modal
$('#bookdetails').modal({
backdrop: 'static',
keyboard: false
}) // put your modal id
$('.something').show().html(r);
}
});
});
});
HTML:
show details
<div id="bookdetails" class="modal fade in" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="false">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h4 class="modal-title">title</h4>
</div>
<div class="modal-body text-justify">
<div class="something" style="display:none;">
</div>
</div>
<div class="modal-footer">
<button type="button" data-dismiss="modal" class="btn btn-primary btn-sm"> close</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div>
But in reality when I click on the link, the modal and data are not shown! How can I fix the problem and show a value in my modal?
DEMO

You have several typo mistakes:
'csrf_token': <?php echo $token; ?>
Should be:
'csrf_token': '<?php echo $token; ?>'
String must be quoted.
Also:
data = {
'bookid': id,
'csrf_token': <?php echo $token; ?>
},
Should be:
data: {
'bookid': id,
'csrf_token': <?php echo $token; ?>
},
Property assignment of an object is performed with : not with = operator.
I have mocked your ajax reuqest and fixed typos mentioned above. Your code works fine:
