Why doesn't Bootstrap modal show without invoking javascript code - html

I created an html page with bootstrap's modal code (copied from Bootstrap's website. I notice that the modal doesn't show unless I call modal('show'). Why? Shouldn't the browser interpret the html and display the modal box? The following code doesn't show the modal but if you comment the script at the end, it will show the modal
<!DOCTYPE html>
<html lang="en">
<head>
<base href="">

<¬- UNCOMMENT THIS AND THE MODAL WILL SHOW-->

Bootstrap modal is designed for trigger the modal window when you click on the element(i.e. a button or a link) with following attributes:
data-toggle="modal" opens the modal window
data-target="#myModal" points to the id of the modal
In your code, no click event occurs and thus modal was not open bydefault
It looks like you want to open modal when page load as the modal is not designed to open on page load you have to manually trigger modal's show Method

since modal works if you clicked on a button to toggle display
this example works fine
see this link https://getbootstrap.com/docs/4.0/components/modal/#live-demo

You can Use this bootstrap modal code this is working fine.

<h2>Modal Example</h2>
<!-- Button to Open the Modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">

<div class="modal-footer">

</div>

That is because modaldiv with the class of modal has a display property set to none by default.
Comment the script and inspect the modal in your browser you will notice that it has a display of none.
When you call .modal() and pass in the parameter show on your modal id, then it's display property gets set to block, which is when you are able to see it.
This is because modals are not supposed to be shown by default but instead on a user event so you can call .modal('show)` on the event.
$('#mydialog').modal('show');

i think it was happen because in head tag you join jquery and bootstrap librrary so your don’t need you code anymore because bootstrap do this for you..

Boostrap Modal not popping up when button is pressed

I'm trying to have a modal pop up, but when I press the button nothing happens.
Here's the HTMl code so far-

When I open the page, a button appears on the top-left corner. Upon pressing it, it dies get highlighted, but nothing happens at all.
Do you have any idea why this is happening, and how to solve it?
here is the problem with your html classes.
look for Bootstrap 5 model
change your html with this or grab from above link
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-bs-toggle="modal" data-bs-target="#exampleModal">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Modal title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
...
</div>
<div class="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>
You have used bootstrap 4 code instead of bootstrap 5 code, either make all your modals the way bootstrap 5 does it, and you can read it here: https://getbootstrap.com/docs/5.0/components/modal/
or just change bootstrap versions to bootstrap 4
The difference is mostly that in bootstrap 5 you use "data-bs" + something in your attributes instead of just "data-"
Add the following script in the head of your html code.
<script src="https://maxcdn.bootstrapcdn.com/bootstrap/4.5.2/js/bootstrap.min.js"></script>

Bootstrap 5 modal not working with starter template [duplicate]

This question already has an answer here:
bootstrap 5 modal not display at all
(1 answer)
Closed 1 year ago.
I'm trying to implement a simple modal using the Bootstrap 5 starter template (I'm using the Bootstrap Bundle with Popper option) but for some reason, it's not working. I've gone through other similar questions but unfortunately, none of them is working for me. I can't figure out where I'm going wrong.
I have attached the simplified code snippet. I'm trying to avoid using javascript to trigger the modal. I want to use the HTML data-* attributes to trigger the modal.

You're probably using some older example/template. Try to use code from the documentation

Can't open modal bootstrap

When I click link,
<a href="#" data-toggle="modal" data-target="#report">
It shows modal well in 1-2 seconds but after that, the modal load page again. So, the content of modal is replaced by the page it loaded. Why?
<div id="report" class="modal fade" role="dialog">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p>Some text in the modal.</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
This is probably because you are using the a tag with a href attribute to open the modal. It will then replace the modal with the content of your href, which is the current page. Try to use a button or something to open your modal:
<button type="button" class="btn btn-primary btn-lg" data-toggle="modal" data-target="#report">Launch modal</button>
EDIT: for the ones that don't believe this is possible and are downvoting me, here is jsfiddle with shows exactly the same behavior that #thai6070 is describing in his question.. This option is deprecated in newer versions of bootstrap.
<link rel="stylesheet" href="https://maxcdn.bootstrapcdn.com/bootstrap/3.4.1/css/bootstrap.min.css">

Paste this code into your head tag.
