Bootstrap Modal not popping up - javascript

I'm really new to bootstrap and I am trying to add a popup using Modals. I added the code and the scripts, but when you click on the button its not popping up. I can tell something is coming up because the background fades a little but a popup is not coming up. So I need a little bit of help figuring out why its not popping up.
My JavaScript links:
<script src="js/jquery-1.10.2.js" type="text/javascript"></script>
<script src="js/bootstrap.min.js" type="text/javascript"></script>
Code for Modals:
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
Close
Save changes
</div>
</div>
<a class="btn" data-toggle="modal" href="#myModal" >Launch Modal</a>

This is a compatibility issue v2.X vs v3.X
Bootstrap 3.0 New Classes & Elements
Modal markup has changed .modal-header .modal-body .modal-footer now get wrapped in .modal-content and .modal-dialog
Modal Migration
How to convert from a 2.x to 3.0 modal:
remove .hide from the .modal (it's now hidden by default)
wrap .modal-header .modal-body .modal-footer inside .modal-content
wrap .modal-content inside .modal-dialog
Events are namespaced. For example to handle the modal 'show' event, use 'show.bs.modal'.
Reference
Bootstrap 3 modal example:
<a data-toggle="modal" href="#myModal" class="btn btn-primary">Launch modal</a>
<div class="modal fade" id="myModal">
<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">Modal title</h4>
</div>
<div class="modal-body">
Content for the dialog / modal goes here.
</div>
<div class="modal-footer">

</div>
</div>
JSFiddle

What I usually do for modals with just JavaScript and Bootstrap is to have an onClick event on the button that executes a JavaScript method that displays the modal.
In your HTML:
<button onclick="myFunction()">Click me</button>
<script>
function myFunction(){
$('#myModal').modal('show')
}
</script>
Just change the function name myFunction to the name you want and myModal to the id of your modal.
Here is the bootstrap docs, where the modal stuff is located, for future reference getbootstrap.com/javascript/

How to make just a part of html 'tabbable'? (Modal Dialog)

I have an Angular App and a custom Modal Dialog implementation. How can I limit the 'tabbablity' of the page so that i can just tab through the Modal, and not everything else in background?
I have set aria-hidden="true" for all other elements directly under the body tag, and thought that has to handle that, but no success. tabindex="-1" also did not work..
Actually I want the exact tab-behaviour of this bootstrap modal:
https://getbootstrap.com/docs/4.0/components/modal/
Click: "launch demo modal" and tab through the modal elements..
How can I achieve this?
Edit: I look at the bootstrap modal, and they do not set anything to other elements, but just to the modal container div (with class="modal fade show") tabindex="-1". And after the last element in modal, tab sets focus to this modal container div. After that the focus is set again to the first modal element. In my case tabindex="-1" strangely does not bring anything, after the last element focus jumps to the Browser's URL Input field and goes on.
I dont know what code you have...but this tabindex behavior works well with bootstarp example.
.modal-backdrop {
background-color: transparent !important;
}

Advice on Modal BootStrap

I am working with boostrap latest version finally getting the hang of it and try to add another modal combined with the one i already have. Well no luck and got stuck. is there a way to add another modal that works together with the previous modal?
the reason why i wanted to try to get another modal in there to show off the twitch emotes plus commands they can use to make it easier for the user.
in other words another box on the right side (where its marked with a red box)
Screenshot: http://i.stack.imgur.com/bJduj.png
This is possible with setting a data-target for the same class instead of using href with an ID. You'll have to adjust the position of them depending on where you want to two and how big they are etc.
Open up the example to full-page and you'll see.
data-target=".myModals"
#myModal2 {
top: 40%;
outline: none;

You can open a modal via JavaScript. Since you already have jQuery loaded, try something like this.
Assuming you have a modals with IDs of videoFeed and textFeed.
$( "#" ).bind( "click", function() {
$('#videoFeed').modal('toggle');
$('#textFeed').modal('toggle');
});

How to create an alert with HTML instead of js

I am trying to figure out how to create an HTML element that is like the JavaScript confirm(); element. I would be fine with just using the JS element, but I am not able to edit the style. Am I able to do this?
Thank You!
You could use Bootstrap alerts for example:
http://getbootstrap.com/javascript/#alerts
There is also http://t4t5.github.io/sweetalert/
Elaborating on Craig's answer, try out the following code to use the Bootstrap framework for an alert that is indeed editable.

bootstrap modal not functioning properly

I'm trying to implement a modal popup on a site using bootstrap. The site is departmental so the only code I've got access to is the body of the site basically (everything else is in php includes for the header, footer, and navigation) I've got the bootstrap.js file included as well as jquery. I'm using the example code on the bootstrap docs. I've got bootstrap tooltips and popovers working but can't figure out why the modal won't work.
<!-- Button to trigger modal -->
Launch demo modal
<!-- Modal -->
<div id="myModal" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 id="myModalLabel">Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
<button class="btn btn-primary">Save changes</button>
</div>
</div>
When I click the button, the page gets backdropped but the only thing in the modal dialog is the navigation bar (I don't have access to the code for that) and the modal dialog in my code (#myModal) is not displayed at all. I have no idea what's going on. This is one my first web development projects.
I want the modal button to be after a select in a form
<select class="bootstrap-select" name=display>
<?php foreach ($digitalSignageDisplays as $display) { ?>
<option value=<?php echo $display; ?>><?php echo $display; ?></option>
<?php } ?>
</select>
Any help would be greatly appreciated. Could it be a Z-index problem?
Make sure you don't forget to wrap your modal-header , modal-body and modal footer with <div class="modal-dialog"> and <div class="modal-content">
<!DOCTYPE html>
<html>
<head>
<link href="D:/install/bootstrap-3.0.0/dist/css/bootstrap.min.css" rel="stylesheet"/>

<div class="modal-dialog">

you Can remove just class hide from 'modal hide fade' and add just modal - content .
Remaining your code is done perfect.
<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>

Launch Bootstrap Modal on Page Load

I don't know JavaScript at all. The Bootstrap documentation says to
Call the modal via JavaScript: $('#myModal').modal(options)
I have no clue how to call this on a page load. Using the supplied code on the Bootstrap page I can successfully call the Modal on an element click, but I want it to load immediately on a page load.
Just wrap the modal you want to call on page load inside a jQuery load event on the head section of your document and it should popup, like so:
JS
<script type="text/javascript">
$(window).on('load', function() {
$('#myModal').modal('show');
});
</script>
HTML
<div class="modal hide fade" id="myModal">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Modal header</h3>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
Close
Save changes
</div>
</div>
You can still call the modal within your page with by calling it with a link like so:
<a class="btn" data-toggle="modal" href="#myModal">Launch Modal</a>
You don't need javascript to show modal
The simplest way is replace "hide" by "in"
class="modal fade hide"
so
class="modal fade in"
and you need add onclick = "$('.modal').hide()" on button close;
PS: I think the best way is add jQuery script:
$('.modal').modal('show');
Just add the following-
class="modal show"
Working Example-
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<div class="container">
<!-- 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 show" 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>
You can try this runnable code-
$(window).load(function()
{
$('#myModal').modal('show');
});
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
<div class="container">
<!-- 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">

<div class="modal-content">
<div class="modal-header">

Update 2021
Bootstrap 5
Now that Bootstrap no longer requires jQuery, it's easy to show the modal using JavaScript..
var myModal = new bootstrap.Modal(document.getElementById('myModal'), {})
myModal.toggle()
Demo
Bootstrap 4
The modal markup has changed slightly for Bootstrap 4. Here's how you can open the modal on page load, and optionally delay display of the modal...
$(window).on('load',function(){
var delayMs = 1500; // delay in milliseconds
setTimeout(function(){
$('#myModal').modal('show');
}, delayMs);
});
<div class="modal fade" id="myModal">
<div class="modal-dialog modal-lg modal-dialog-centered" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title">My Modal</h4>
<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 mx-auto" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
Demo
regarding what Andre's Ilich say you have to add
the js script
after the line in what you call the jquery:
<script src="//ajax.aspnetcdn.com/ajax/jQuery/jquery-2.1.1.js" type="text/javascript"></script>
<script type="text/javascript">
$(window).load(function(){
$('#myModal').modal('show');
});
</script>
in my case that was the problem hope it helps
Tested with Bootstrap 3 and jQuery (2.2 and 2.3)
$(window).on('load',function(){
$('#myModal').modal('show');
});
<!-- 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"><i class="fa fa-exclamation-circle"></i> //Your modal Title</h4>
</div>
<div class="modal-body">
//Your modal Content
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Fechar</button>
</div>
</div>
</div>
</div>
https://jsfiddle.net/d7utnsbm/
In my case adding jQuery to display the modal didn't work:
$(document).ready(function() {
$('#myModal').modal('show');
});
Which seemed to be because the modal had attribute aria-hidden="true":
<div class="modal fade" aria-hidden="true" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
Removing that attribute was needed as well as the jQuery above:
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
Note that I tried changing the modal classes from modal fade to modal fade in, and that didn't work. Also, changing the classes from modal fade to modal show stopped the modal from being able to be closed.
You can activate the modal without writing any JavaScript simply via data attributes.
The option "show" set to true shows the modal when initialized:
<div class="modal fade" tabindex="-1" role="dialog" data-show="true"></div>
Heres a solution [without javascript initialization!]
I couldn't find an example without initializing your modal with javascript, $('#myModal').modal('show'), so heres a suggestion on how you could implement it without javascript delay on page load.
Edit your modal container div with class and style:
<div class="modal in" id="MyModal" tabindex="-1" role="dialog" style="display: block; padding-right: 17px;">
Edit your body with class and style:
<body class="modal-open" style="padding-right:17px;">
Add modal-backdrop div
<div class="modal-backdrop in"></div>
Add script
$(document).ready(function() {
$('body').css('padding-right', '0px');
$('body').removeClass('modal-open');
$('.modal-backdrop').remove();
$('#MyModal').modal('show'); });
What will happen is that the html for your modal will be loaded on page load without any javascript, (no delay). At this point you can't close the modal, so that is why we have the document.ready script, to load the modal properly when everything is loaded. We will actually remove the custom code and then initialize the modal, (again), with the .modal('show').
Like others have mentioned, create your modal with display:block
<div class="modal in" tabindex="-1" role="dialog" style="display:block">
...
Place the backdrop anywhere on your page, it does not necesarily need to be at the bottom of the page
<div class="modal-backdrop fade show"></div>
Then, to be able to close the dialog again, add this
<script>
$("button[data-dismiss=modal]").click(function () {
$(".modal.in").removeClass("in").addClass("fade").hide();
$(".modal-backdrop").remove();
});
</script>
Hope this helps
In addition to user2545728 and Reft answers, without javascript but with the modal-backdrop in
3 things to add
a div with the classes modal-backdrop in before the .modal class
style="display:block;" to the .modal class
fade in together with the .modal class
Example
<div class="modal-backdrop in"></div>
<div class="modal fade in" tabindex="-1" role="dialog" aria-labelledby="channelModal" style="display:block;">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h4 class="modal-title" id="channelModal">Welcome!</h4>
</div>
<div class="modal-body" style="height:350px;">
How did you find us?
</div>
</div>
</div>
</div>
<div id="ModalStart" class="modal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-body">
<p><i class="icon-spinner icon-spin icon-4x"></i></p>
</div>
</div>
You can show it on start even without Javascript. Just delete the class "hide".
class="Modal"
Update 2020 - Bootstrap 5
Building on the excellent responses from previous answers, in Bootstrap 5 with no jQuery, this has worked;
document.querySelector('[data-target="#exampleModal"]').click();

In bootstrap 3 you just need to initialise the modal through js and if in the moment of the page load the modal markup is in the page the modal will show up.
In case you want to prevent this, use the option show: false where you initialise the modal. Something like this:
$('.modal').modal({ show: false })
you can using jQuery to handle this
first import on your template
<script src="https://code.jquery.com/jquery-3.6.0.min.js" integrity="sha256-/xUj+3OJU5yExlq6GSYGSHk7tPXikynS7ogEvDej/m4=" crossorigin="anonymous"></script>
and hit the id on your modal with jQuery Script
<script type="text/javascript">
$(window).on('load', function() {
$('#staticBackdrop').modal('show');
});
</script>
here is the modal for case display django message
{% if messages %}
{% for message in messages %}
<div class="modal fade" id="staticBackdrop" data-bs-backdrop="static" data-bs-keyboard="false" tabindex="-1" aria-labelledby="staticBackdropLabel" aria-hidden="false">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="staticBackdropLabel">Message</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
{{ message }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
{% endfor %}
{% endif %}
You may want to keep jquery.js deferred for faster page load. However, if jquery.js is deferred the $(window).load may not work. Then you may try
setTimeout(function(){$('#myModal').modal('show');},3000);
it will popup your modal after page is completely loaded (including jquery)
In order to avoid bootstrap being overruled and loosing it´s funcionality, simply create a regular launch button, provide it with an Id, and 'click it' using jquery, like so:
The launch button:
<button type="button" id="btnAnouncement" class="btn btn-primary" data-toggle="modal" data-target="#modalAnouncement">
See what´s new!
</button>
The jQuery trigger:
$(document).ready(function () {
$('#btnAnouncement').click();
)}
Hope it helps. Cheers!
I recently needed to launch a Bootstrap 5 modal without jQuery and not with a button click (eg, on page load) using Django messages. This is how I did it:
Template/HTML
<div class="modal" id="notification">
<div class="modal-dialog modal-dialog-centered">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title">Notification!</h5>
<button type="button" class="btn-close"
data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
{% for m in messages %}
{{ m }}
{% endfor %}
</div>
<div class="modal-footer justify-content-between">
<a class="float-none btn btn-secondary" href="{% url 'some_view' %}"
type="button">
Link/Button A
</a>
<button type="button" class="btn btn-primary"
data-bs-dismiss="modal">
Link/Button B
</button>
</div>
</div>
</div>
</div>
JS in a file or in the template
{% block javascript %}
{{ block.super }}
<script>
var test_modal = new bootstrap.Modal(
document.getElementById('notification')
)
test_modal.show()
</script>
{% endblock javascript %}
This method will work without the Django template; just use the HTML and put the JS in a file or script elements that loads after the Bootstrap JS before the end of the body element.
maybe it's late but, once I was not able to solve this order issue, and modal was not getting shown; I used jquery click();
I tried this and it worked well :)
create a button, which calls Modal show > style that button as display : none;
Example :
$( "#clickme" ).click();
<html>
<head>
<link rel="stylesheet" href="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/css/bootstrap.min.css">
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.12.0/jquery.min.js"></script>
<script src="http://maxcdn.bootstrapcdn.com/bootstrap/3.3.6/js/bootstrap.min.js"></script>
</head>
<body>
<input type="button" value="0" id="clickme" style="display:none;" data-toggle="modal" data-target="#exampleModal" />
<!-- Modal -->
<div id="exampleModal" class="modal" 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">Clicked Successfully</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>
</body></html>
In JS:
<script>
$(document).ready(function(){
$("#myModal").modal('show');
});
</script>
Boostrap Modal in HTML:
<!-- Modal content-->
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h4 class="modal-title">Alert</h4>
</div>
<div class="modal-body">
<p><?= session('msg') ?></p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
replace myModal with your's
