Nouvelle Chirurgie
So, what should I do?

You can use bootstrap for this
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalCenter">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
{{ form }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>

Find the active bootstrap modal using javascript

I do have dynamically generated modals with different Ids in it. I want to know which modal is opened/ shown to the user. I have a solution, If I do know the id of the model as
$('#modelId').on('show.bs.modal', function (event) { // modelId is dynamic
var button = $(event.relatedTarget);
var productid = button.data('target');
console.log(productid)
});
But How to get the modalId when we do not know which modal is triggered by the user?

Attach the event listener to the document instead. Example:
$(document).on('show.bs.modal', function(event) { // modelId is dynamic
var button = $(event.relatedTarget);
var productid = button.data('target');
console.log(productid)
});

Capture BootstrapNative Modal close event without jQuery

I'm using Bootstrap-Native, I want to detect when a modal is closed, is there a way to do this with plain javascript?
<!-- Modal -->
<div class="modal fade" id="exampleModal" 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">Modal title</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
</div>
</div>
I tried:
document.getElementById("exampleModal").addEventListener("transitionend", console.log("closed"));
But event doesn't fire.

This question can be found repeated here: Bind a function to Twitter Bootstrap Modal Close.
See the answer:
var myModalEl = document.getElementById('myModalID');
myModalEl.addEventListener('hidden.bs.modal', function (event) {
// do something...
});

instead of taking to a different page, open page in modal

I'm not sure if this is possible but what I'm trying to do is when user clicks a button then instead of taking the user to a different page, I want the new page to be opened in a modal, and be active there. I'm using twitter bootstrap. is it possible to do that?
bootstrap modal:
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">

hello

how to contribute body of modal in bootstrap 3?

The requirement-My applicaiton has a button which when clicked a modal is supposed to pop-up where there will contain some data.
Architecture-I want the modal data to be contributed from some another application(some url),through a php file.How can this be done?
What I have tried-In the php file i have placed
<?php echo ' <div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">...</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>
In the html I am using this
<div id="prerequisites-container" class="container-fluid">
<a href="http://localhost/Experiment/main/prereq.php"
data-toggle="modal" data-target="#myModal" class="btn btn-default">
Launch Modal </a>
<div class="modal fade" id="myModal" tabindex="-1" role="dialog"
aria-labelledby="myModalLabel" aria-hidden="true"></div>
</div>

Place your HTML code, as follows:
<div class="modal fade" id="myModal" tabindex="-1" role="dialog"
aria-labelledby="myModalLabel" aria-hidden="true"></div>
inside your Echo.
<?php echo ' HERE <div class="modal-dialog">
UPDATED:
<div id="prerequisites-container" class="container-fluid">
Launch Modal
</div>
<?php echo '<div class="modal fade" id="trymodalbootstrap" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true"></div>
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal"
aria-label="Close">
<span aria-hidden="true">×</span>
</button>
<h4 class="modal-title" id="myModalLabel">Modal title</h4>
</div>
<div class="modal-body">...</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</div>
</div>'; ?>

place the modal html in your html, and fetch modal content data dynamically through ajax call from server. and add that data to modal before displaying
