I need to be able to change the content inside a modal depending on the button that is clicked.
For instance, if button one is clicked it will only show the div with class 'one' and the others will remain hidden.
$('#exampleModalCenter').modal('toggle')
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button type="button" class="btn" data-toggle="modal" data-target="#exampleModalCenter">one</button>
<button type="button" class="btn" data-toggle="modal" data-target="#exampleModalCenter">two</button>

<div class="modal fade" id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalCenterTitle" aria-hidden="true">

</button>
</div>
<div class="modal-body">
<div class="one">Button one content</div>
<div class="two">Button two content</div>
<div class="one">Button three content</div>
</div>
</div>
</div>
</div>
Example below. The logic: Whenever you click a button, hide all the content first, then you show the specific content based on the button you clicked.
Ref.: https://getbootstrap.com/docs/3.3/javascript/#modals-related-target
$(".btn").click(function () {
$(".parent").children().each(function () {
$(this).hide();
});
$(`div.${$(this).attr("id")}`).show();
});

You can look at this tutorial :
https://getbootstrap.com/docs/3.4/javascript/#modals-related-target
Simply add a data attribute to your button :
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#yourModal" data-name="one">Open modal for One</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#yourModal" data-name="two">Open modal for Two</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#yourModal" data-name="three">Open modal for Three</button>
And when the event occur, you can recover the attribute of the button and adapt the behavior according to it :
$('#yourModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget); // Button that triggered the modal
var recipient = button.data('name'); // Extract info from data-* attributes
// Here, you can change the behavior according to the button clicked :
switch(recipient) {
case 'one':
$('.one').show();
break;
case 'two':
$('.two').show();
break;
// etc...
}
});
You could subscribe to the modal's show.bs.modal event, check the value of the relatedTarget property of the event and then show/hide internal divs based on that target value
$(document).on("click",".modal-open",function(){
var button_val = $(this).attr("data-val");
$('#exampleModalCenter').modal('show');
$(".conditional-div").hide();
$("#exampleModalCenter ."+button_val).show();
})
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<button type="button" class="btn modal-open" data-val="one" >one</button>
<button type="button" class="btn modal-open" data-val="two" >two</button>
<button type="button" class="btn modal-open" data-val="three" >three</button>

I'm using a Bootstrap Modal and the modal-footer div is displayed with the grey background used to block out the main page instead of the white background used by the rest of the modal.
It's a somewhat complicated set up but I'll do my best to explain it.
The modal definition looks like this:
<div class="modal fade" role="dialog" tabindex="-1" id="concert-modal">
<div class="modal-dialog" role="document">
<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 id="concert-modal-title" class="modal-title"></h4>
</div>
<div id="concert-modal-body" class="modal-body">
</div>
</div>
<div class="modal-footer">
<span id="ConcertMessage" class="pull-left"></span>
<button class="btn btn-default" type="button" data-dismiss="modal">Cancel </button>
<button class="btn btn-primary" type="submit" form="concert-modal-form">Save </button>
</div>
</div>
You'll see that the modal-body section is empty. That's because I have javascript that uses the Mustache.js templating system to set the html of the body using a template and the return from an Ajax call. That all works correctly and the modal body is displayed correctly.
The modal body consist of a Bootstrap tab control and a form that contains all the tab panes, so the overall structure looks like this.
<ul class="nav nav-tabs nav-justified nav-justify">
<li class="active">Basic </li>
<li>Media </li>
<li>Tickets </li>
</ul>
<form id="concert-form" action="#" class="form-horizontal">
<div class="hidden">
<input type="text" name="Mode" id="Mode">
<input type="text" name="ConcertID" value="{{ConcertID}}">
</div>
<div class="tab-content" style="margin-top:20px;">
... form-group divs with labels and input controls...
</div>
<div class="tab-content" style="margin-top:20px;">
... form-group divs with labels and input controls...
</div>
</form>
I've used an html syntax checker to make sure I don't have any unclosed tags. I've also tried placing the form tag in several different places in the code but no matter what I do, the modal-footer section does not display correctly.
Any ideas?
You have your footer outside the modal-content div.
Structure should go:
<div class="modal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header"></div>
<div class="modal-body"></div>
<div class="modal-footer"></div>
</div>
</div>
</div>
You have it as this (your missing a div in the html you posted btw):
<div class="modal">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header"></div>
<div class="modal-body"></div>
</div>
<div class="modal-footer"></div>
</div>
</div> <!--missing div in the example you posted here-->
Functioning code below so you can see the correct structure in action:
$(document).ready(function(){
$('#concert-modal').modal('show');
});

I have a ussual modal window of Bootstrap and there I have a div which is hidden by default. I want to click on link (which is also inside this modal) and display it. Problem is that I could't make click on link and therefore my div still hedden.
Maybe someone had same problem or can give me good advice how to solve this task?
sorry that I did't post the code before I asked

I have tried it. Please have a look.
$(document).ready(function(){

You have to give us more details. But classical problems here could be a delegation event problem with your link.
Ask you this question: Does your link exist at the moment you add the on("click" ... ?
$('#link').click(function() {
$('#div').css('display','block');
});
This is just an example. Its better if you can post your code here.
I have the modal window (bootstrap 3):
<div class="modal fade" id="modal1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
TITLE
</div>
<div class="modal-body">
TEXT
</div>
<div class="modal-footer">
<form><input class="btn btn-success" type="button" value="NEXT" data-toggle="modal" data-dismiss="modal" data-target="#modal2"/></form>
</div>
</div>
</div>
By clicking on "NEXT" button, #modal1 is closing and #modal2 is opening:
<div class="modal fade" id="modal2">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
TITLE
</div>
<div class="modal-body">
TEXT //lots of text
</div>
<div class="modal-footer">
<form><input class="btn btn-success" type="button" value="EXIT" data-dismiss="modal"/></form>
</div>
</div>
</div>
Scrolling is working fine in the first modal window #modal1, but in the #modal2 it is not working, there is not even the scrollbar.
So, the question is: How to make the scrolling work in the second window?
UPD: added jsfiddle: http://jsfiddle.net/386ozdb7/2/
If you indent your code correctly you can see that div with class "modal-footer" are not inside the div with "modal-content" as the documentation suggest. Maybe that can be the problem of scrollbar with a lot of text
<div class="modal fade" id="modal1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
TITLE
</div>
<div class="modal-body">
TEXT
</div>
</div>
<div class="modal-footer">
<form><input class="btn btn-success" type="button" value="NEXT" data-toggle="modal" data-dismiss="modal" data-target="#modal2"/></form>
</div>
</div>
Try to change your 2 modals as below:
<div class="modal fade" id="modal1">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
TITLE
</div>
<div class="modal-body">
TEXT
</div>
<div class="modal-footer">
<form><input class="btn btn-success" type="button" value="NEXT" data-toggle="modal" data-dismiss="modal" data-target="#modal2"/></form>
</div>
</div>
</div>
</div>
check the bootstrap example at: http://getbootstrap.com/javascript/#modals
ps: always indent your code.. it's useful to reduce markup error!
Thats the problem: http://getbootstrap.com/javascript/#overlapping-modals-not-supported
Overlapping modals not supported
Be sure not to open a modal while another is still visible. Showing more than one modal at a time requires custom code.
This may help you: https://github.com/jschr/bootstrap-modal
Solution:
.modal {
overflow-y: auto;
}
.modal-open {
overflow: auto;
}
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">

Think u have your complete answer.
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>

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();

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();
Full snippet:
window.onload = () => {
document.querySelector('[data-target="#exampleModal"]').click();
}
<script src="https://stackpath.bootstrapcdn.com/bootstrap/5.0.0-alpha1/js/bootstrap.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/popper.js#1.16.0/dist/umd/popper.min.js"></script>
<link href="https://stackpath.bootstrapcdn.com/bootstrap/5.0.0-alpha1/css/bootstrap.min.css" rel="stylesheet" />
<div class="container py-3">
<!-- 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" 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="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>
</div>
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
