Problems with showing a modal using bootstrap - javascript

I'm trying to use a bootstrap modal window using the code from their website. Unfortunately the window doesn't function properly when I use it, for some reason.
I used this sample:
<button type="button" class="btn btn-primary" data-toggle="modal" data-target=".bs-example-modal-sm">Small modal</button>
<div class="modal fade bs-example-modal-sm" tabindex="-1" role="dialog" aria-labelledby="mySmallModalLabel">
<div class="modal-dialog modal-sm" role="document">
<div class="modal-content">
...SOME MORE CONTENT HERE...
</div>
</div>
</div>
All I get is the faded screen and the modal itself is somewhere above the layout and not seen within the browser window. What might be the problem here?


your code is correct you just need to add content

Open custom bootstrap modal with vanilla JavaScript on DoubleClick event

I want to open custom bootstrap modal using data from an object when double clicked on an element.
How to do this using vanilla JavaScript.
Also how to add all functionalities in it :
Ease Transition
Modal should remove when clicked on cross or outside of body
always clear the previous data(no caching)
https://jsfiddle.net/awo0hq4c/
NOTE : Modal used is basic bootstrap modal which is given below but instead of button it is a div in my case
<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">
<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>```

Append this line of code into the last line of showModal() function.
new bootstrap.Modal(modalItem).show();
https://getbootstrap.com/docs/5.0/components/modal/#via-javascript
const div = document.querySelector('.container');
div.addEventListener('dblclick', (event) => {
showModal({
id: '1',
title: 'Title Modal',
value: 'this is modal content',
});
});
const showModal = (data) => {
console.log(data, 'here is');
const modalItem = document.getElementById('exampleModal');
modalItem.innerHTML = '';
modalItem.innerHTML = ` <div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">${data.title}</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
${data.value}
</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>

bootstrap modal wont open on page load

My bootstrap modal wont open on page load I do not know why.
The button to open the modal works tho.
My code:
<div id="myModal" 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>
window.onload = function() {
$('#myModal').modal('show');
}

Your case may be already answered thousand times, but consider few these causes:
Order of your libraries, are they in correct position?
Perhaps you forget to include bootstrap.js
Consider to include popper.js
Please let me know, if it helps

Try this code, it works for me. it is built with bootstrap 5.1:

Simple Modal Won't Show

I know this is probably a really simple, dumb issue, but I've searched around and can't seem to figure out what my problem is. I copied and pasted the example straight from the bootstrap website, and I can't get a modal to pop up on the screen no matter what I do.

Your problem is the references of bootstrap. Look at that example.

I would check the location of your JS/CSS files. Looks like a funky path you have in there; make sure you're pointing to the right folder or using an up-to-date cdn (the examples on their website use cdns I believe).
Just for reference, you can use https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/css/bootstrap.min.css for the stylesheet
and https://maxcdn.bootstrapcdn.com/bootstrap/3.3.7/js/bootstrap.min.js for the javascript. Also make sure you have a jQuery reference in there (https://code.jquery.com/) as this is needed for much of bootstrap's javascript functionality.
Note: Be sure to add the reference to jQuery BEFORE the reference to boostrap.js!
EDIT
I see Leo Rossetti just beat me to it, use his example as it appears to work.

Why does my modal not work? Bootstrap4

I wonder why my Bootstrap 4 modal is not working. Any clue? I literally copy and paste from the Bootstrap 4 website (http://v4-alpha.getbootstrap.com/components/modal/#live-demo) Also, I have added js that they say.
Please find below the code.
Thanks
I have checked other posts and I didn't have luck
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus()
})

There are typo in your snippet (unused }); at the end), but most importantly your toggle button is targeting the wrong modal id. Make sure data-target is the id of the modal you're targeting:
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>
Demo:
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus()
})

You have some script error and your data-target="#exampleModal" does not match with the model's ID

I landed here because I was having the same error. After going back and reading a bit. I ran into the following:
If you’re using our compiled JavaScript, don’t forget to include CDN versions of jQuery and Popper.js before it.
Because I downloaded bootstrap 4 and copied the folders as I used to with bootstrap v3, I assumed it was all going to work.
Download section has the CDN for popper and jQuery
https://getbootstrap.com/docs/4.0/getting-started/download/
hope this helps... Nessio

<script>
$(document).ready(function() {
$("#MyModal").modal();
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus();
});
});
</script>

Looks like the data-target name you entered in not correct.
Here is the correct code of your button
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#myModal">
Launch demo modal
</button>

your data target is wrong: #exampleModal, should be #myModal.
also, you have incorrect syntax in your js code
$(document).ready(function() {
$("#MyModal").modal();
});
})//remove this
$('#myModal').on('shown.bs.modal', function() {
$('#myInput').focus()
});

<!--JS below-->
<!--modal-->
<script>
$(document).ready(function() {
$("#MyModal").modal();
});
</script>
</html>

I faced the same error but for a different reason(...rather silly). I was using thymeleaf layout and accidentally put the modal div outside the content fragment.
<div layout:fragment="content">
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#someId">Open</button>
...
</div>
<div class="modal" id="someId">
</div>
So, although the modal div was present in the code, it was not rendered on the DOM(checked with View Page Source). It fails silently without any errors/warnings. Please ensure that the modal div is rendered on the DOM.

My issue was exactly explained here. https://stackoverflow.com/a/49039205/9855327
In my case, it is not related with wrong references id, it was because I created a modal inside a table in a loop in C# / Aspnet MVC. Se I created a modal for each table row.
I just inserted the code below at the end body tag:
<script>
jQuery(document).ready(function () {
jQuery("body").children().first().before($(".modal"));
});
</script>
It will move all modals HTML elements to the beginning of the body and for me was enough.

How to make modal visible by default when html page runs

I am creating a pop up div (modal) which will appear on screen by default. However I succeed to open it on button click but I want it open by default whenever I run the HTML page.
Here is my code.
<!DOCTYPE html>
<html lang="en">
<head>
<title>Bootstrap Example</title>
<meta charset="utf-8">
<meta name="viewport" content="width=device-width, initial-scale=1">
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
</head>
<body>
<div class="container">
<h2>Modal Example</h2>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<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>
</div>
</body>
</html>
Where I am showing the modal using a button.In that I am using data-target property to invoke the modal. So how to do it without any click event?

Add class in to html code , such that
<div class="modal fade show d-block" id="newModal" role="dialog">
or you can call the following function when the page loads
$('#newModal').modal('show');

Use .modal('show') to show the model manually
$(document).ready(function() {
$('#myModal').modal('show');
});
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.5/js/bootstrap.min.js"></script>
<div class="container">
<h2>Modal Example</h2>
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open Modal</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog">
<!-- Modal content-->
<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>
</div>

Sorry I've not enough reputation to add a comment.
according to bootstrap modal component documentation, there's no need to pass any parameter to .modal() method.
$(document).ready(function() {
$("#myModal").modal();
});

Add class in to <div class="modal fade" id="myModal" role="dialog">, such that
<div class="modal fade in" id="myModal" role="dialog">
or you can call the following function when the page loads
$('#myModal').modal('show');

open modal at document.ready()
for eg.
$(document).ready(function (){
//open modal here
$('#myModal').show();
});
