I want to insert an image in Modal but I need to use the value of the variable data-image as it will change according to the value of the image.
<script type="text/javascript">
$('#myModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var title = button.data('title')
var overview = button.data('overview')
var image = button.data('image')
var url = "<img src='https://image.tmdb.org/t/p/w600_and_h900_bestv2/+image+'></img>"
var modal = $(this)
modal.find('#title').text(title)
modal.find('#image').attr('src',url)
modal.find('#overview').text(overview)
})
</script>
<a href="#" role="button" data-id="{{$item['id']}}" data-title="{{$item['title']}}" data-image="{{$item['imagem']}}" data-overview="{{$item['overview']}}" data-toggle="modal" data-target="#myModal">
<div class="modal fade bd-example-modal-lg" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle"><div id="title"></div></h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<p><div id="image"></div></p>
<p><div id="overview"></div></p>
</div>
</div>
</div>
I tried to use some shapes like text, val, innerhtml, but it didn't work. What is the best way to make it work what I need?
You need to use an img element as oppose to a div to set display your img and other content dynamically in your modal.
The reason its not working is DOM content is ready and you are applying styles to a div and it can not load an image asynchronously thats why you are not seeing anything.
I have added demo data and few other button to show that its all working now with different data coming from data-attributes.
Live Working Demo:
$('#myModal').on('show.bs.modal', function(event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var title = button.data('title')
var overview = button.data('overview')
var image = button.data('image')
var modal = $(this)
modal.find('#title').text(title)
modal.find('#image').attr('src', image)
modal.find('#overview').text(overview)
})

First, understand what a modal dialog is: it is just a div (with content) that is positioned so that it sits on top of the rest of the page, usually accompanied by another div that sits directly underneath it and partially darkens the rest of the page while preventing the user from clicking on anything underneath. These two divs begin hidden, but can be displayed based on user activity, and then re-hidden.
The modal word indicates that this div structure has the focus - the user cannot interact with any other part of the page until the modal dialog is closed. This is accomplished via that second (overlay) div that is height/width 100% and is positioned (via z-index) to stack between the dialog and the rest of the page.
The important thing to note is that they are just ordinary div structures that exist on the page - or that are added to the page - at will. That means, you can change the content (text or html) inside the modal div structure as easily as you can change the content of any other div. There is nothing different about a modal div structure at all.
Bootstraps modal dialogs are exactly the same, but they include some extra sizzle that add some extra visual coolness and that make them a bit easier to work with. Other than that, they are exactly like self-made modal dialogs - which are exactly like ordinary div structures.
To demonstrate, we'll create a super-simple home-made modal dialog and use it to do what you request.
Note the following about the home-made modal dialog:
(a) We use position:fixed or position:absolute to remove the modal div structure from the usual HTML flow - allowing it to sit on top of the rest of the page.
(b) We use z-index to position the modal div structure ABOVE the rest of the page
(c) We add a second div (the "overlay") that sits on top of the page, but underneath the modal. Its purpose is to darken the page underneath the modal dialog and to prevent the user from clicking anything on the page until they finish with the dialog.
$('button').click(function(){
let img = $('#modal').data('image');
$('#modal-content').html(`<img src="${img}" />`);
$('#overlay, #modal').fadeIn();
});
$('#modal-close').click(function(){
$('#overlay, #modal').fadeOut();
});
#overlay{z-index:998;position:fixed;top:0;left:0;width:100%;height:100%;background:rgba(0,0,0,.7);}
#modal{z-index:999;position:fixed;top:15vh;left:25vw;width:50vw;height:30vh;}
#modal-close{position:absolute;top:0;right:0;padding:10px;font-size:2em;border:1px solid grey;}
#modal-close:hover{color:dodgerblue; border:1px solid dodgerblue;cursor:pointer;}
#overlay, #modal{display:none;}
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<div id='overlay'></div>
<div id='modal' data-image='http://placekitten.com/400/300'>
<div id='modal-close'>X</div>
<div id='modal-content'></div>
</div>
<button>Show Modal</button>

I'm using Bootstrap Modal to load lightboxes with some resource-heavy content.
But the content is loaded immediately with the page. And since there's several lightboxes it slows the page down significantly.
I want the content to load only when the modal button is clicked. But I don't want to call the modal code from a separate page, since that would complicate everything.
Is there some way to use JS or AJAX to load the modal content only when the modal box opens?
Somehow trigger it to load when the button is clicked and then turn the content off, when the box is closed.
Also bear in mind that I don't know almost anything about JS or AJAX.
--EDIT: It would be great if the same solution could be applied to tabbed content--
The code I'm using:
<!-- Trigger the modal with a button -->
<button type="button" class="btn btn-info btn-lg" data-toggle="modal" data-target="#myModal">Open</button>
<!-- Modal -->
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<iframe width='100%' height='368' src='#' frameborder='0' allowfullscreen></iframe>
</div>
</div>
</div>
</div>
I have'a modal ( I use twitter bootstrap 2.3.2 and I need to use it please dont say to use bootstrap3), and I want to show different content based on the clicked button. In other words, there are multiple buttons that are added dynamically into dom, and based on the clicked button, I need to show different content. Currently, it always shows the content of the first clicked button no matter where I'am pushing. Here is my code:
<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">Query Name</h3>
</div>
<div class="modal-body">
<div id="graph" style="position:relative;overflow:hidden;cursor:default;" class="{{getViewType}}">
<center id="splash" style="padding-top:230px;">
<img src="../images/loading.gif">
</center>
</div>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
</div>
And this is my handler:
$(document).on('hidden','#myModal',function(){
console.log('it comes here'); // this is printed every time I close modal
$(this).removeData('modal');
});
Perhaps check that the id's of the dynamically added buttons are unique. Also that any function code that will run when they're clicked, is also dynamically added otherwise it won't run. It would certainly help to see the code for the buttons.
DEMO
Ok.. I prefer .shown event of modal for this case and a global variable to store the data of clicked button as below
var dataToShow=""; //global variable
//A button click event to store data
$('button').on('click',function(){
dataToShow=$(this).text();//For DEMO purpose am storing text of button clicked in dataToShow
});
$(document).on('shown','#myModal',function(){
//Will be triggered when modal is opened
alert(dataToShow);//Just for verification
$('.modal-body .datadisplay').html(dataToShow);
//assign the value in a separate div inside modal-body so that you will not replace anything else each time
});
Now since the button is dynamically created, I would suggest to use event delegation here to attach event to button
$(document).on('click','.yourbuttonClass',function(){
dataToShow=$(this).text();
});
Now if you want you can make use of
$(document).on('hidden',"#myModal",function(){
//clear the contents inside an element added i.e. .datadisplay inside modal-body
$('.modal-body .datadisplay').empty();
})
I am using modal from bootstrap
<div aria-hidden="hide" aria-labelledby="myModalLabel" role="dialog" tabindex="-1" id="myModal" class="modal fade" style="display: none;">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<h4 id="myModalLabel" class="modal-title"></h4>
</div>
<div id="myModalBody" class="modal-body modalScroll"></div>
<div class="modal-footer">
<button data-dismiss="modal" class="btn btn-default" type="button">Close</button>
</div>
</div>
</div>
</div>
This is my main modal box and I send some information and show modal when I need to inform user at the moment. But my idea is using this modal to show images and when user choose one I will save as avatar. So I created function like below:
<script>
$('#avatar').click(function() {
showMessage();
});
$('#eee').on('click', function() {
alert('333');
});
function showMessage(){
var txto = '<div id="eee">test me test</div>';
$('#myModalLabel').append('Coose Your avatar');
$('#myModalBody').append(txto);
$('#myModal').modal('show');
}
</script>
Now when I go on page and click div id = avatar I will see modal window but when I click: test me I have no result. So is it some way to do this?
try adding:
$('#eee').on('click', function() {
alert('333');
});
inside showMessage() ... your problem is that you have to rebind events to dynamically added elements if they are added after (document).ready or in this case the page rendering...
whenever i do this i just make a big function called rebindEvents() that I can call into to let the page know about my new items... just a warning, its not great for performance if you wind up with a lot of jquery elems you have to deal with, knockout is a much better library for dealing with dynamic html then doing it this way.
also, i'm assuming you are going to present a list of avatars, so you may want to swap eee to a class instead of id...
I just attached a bootstrap modal to a button on a Wordpress site, and it's working great.
But the problem is, the modal hides the navigation menu (specifically the "blog" link) when it's inactive, the first time. After you open the modal and close it out, the modal disappears and the menu works fine.
I've tried a few things, like fiddling with the z-index, and also I tried hacking a script together:
<script>
jQuery(document).ready(function() {
jQuery('#subscribe').modal('hide')
});
</script>
So far, no dice. But maybe you can tell from the script, I'd just like to put the modal on hidden state when the page loads, and only have it called when they click the button.
Here's my site. If you try clicking on the "blog" link on a laptop or smaller screen, you can't, because it's hidden by the modal:

Appreciate any help!
Ok I found the solution
You must add a class called hide. Because fade function is to set opacity:0 of the div. So its just hide in-front of the page.
So your line should be
<div id="subscribe" class="modal hide fade" role="dialog">

I'm using twitter bootstrap's modal window to load a remote image
<img alt="250x150" src="/assets/250x150.gif">
I'm following these docs
The image is not rendering correctly in the modal.
I get a load of jumbled data instead -
What's happening? How can I fix?
Yes, I had this too. The answer I found is here.
I created a link like this:
<a href="gallery/blue.jpg" class="thumbnail img_modal">
//handler for link
$('.img_modal').on('click', function(e) {
e.preventDefault();
$("#modal_img_target").attr("src", this);
$('#modal').modal('show');
});
//and modal code here
<div id="modal" 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">Title to go here</h3>
</div>
<div class="modal-body">
<img id="modal_img_target">
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal" aria-hidden="true">Close</button>
</div>
</div>
When using href to specify remote content for a modal, Bootstrap uses jQuery's load method to fetch the content, and then sticks the retrieved content into the modal's body element. In short, it only makes sense when the remote content (the href value) loads HTML or text.
What you're seeing is expected, as it's the same thing that would happen if you opened the gif file in a text editor, and just pasted it into an HTML tag.
To have it work the way you want, the href needs to point to an HTML document that contains an <img> tag that references the image you want in the modal.
In post of Mark Robson – change 'this' to 'this.href':
$("#modal_img_target").attr("src", this);
=>
$("#modal_img_target").attr("src", this.href);
