I am trying to achieve the following:
When the page loads, the focus goes to the first element in the form.
When the button is pressed on form, a modal appears to confirm and the focus should be on the "Proceed" button inside modal dialog.
I managed to to make the first one work, but for the second I have no idea why it is not working. Following is my code.
HTML
<form method="post" {% if action %} action="{{ action }}" {% endif %} role="form" enctype="multipart/form-data">
<!-- Modal -->
<div class="modal fade" id="confirmationModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel">
<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 class="modal-title" id="myModalLabel">Confirmation</h4>
</div>
<div class="modal-body">
{{ confirm | default: "Would you like to proceed?" }}
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="submit" id="submit-main-form" class="btn btn-primary">
<i class="fa fa-save"></i> {{ submit_text | default: "Proceed" }}
</button>
</div>
</div>
</div>
</div>
</form>
Script
/* Sets focus on the first element of the form */
$(document).ready(function() {
$('form:first *:input[type!=hidden]:first').focus();
$("#confirmationModal").on('show.bs.modal', function(event) {
// not setting focus to submit button
$("#submit-main-form").focus();
});
});
You are using show.bs.modal which Occurs when the modal is about to be shown
I believe you need shown.bs.modal event which Occurs when the modal is fully shown along when all the CSS transitions are completed.

I use a modal to dynamically load content to the user (thanks to AJAX and the link he clicked)
On one of the Ajax pages that I load I added a date field with the bootstrap-datepicker plugin (https://bootstrap-datepicker.readthedocs.io/en/latest/)
The problem is that when I click on the input to add the date, it is as if the modal is reloading and I cannot block it
I created a simple example to show the problem (but suddenly on my site, when I click on the date field, it reloads the page at AJAX)
http://jsfiddle.net/1L32hyzt/
HTML:
<!-- 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" 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">
<input type="text" name="date_from" class="form-control date-test date-from" placeholder="" value="" autocomplete="off">
</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>
Javascript:
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget)
var modal = $(this)
//......
console.log('MODAL SHOW')
$('.date-test').datepicker();
$('.modal-body').prepend('<div><strong>MODAL SHOW</strong></div>')
});
As you can see, when we click on this input, it reloads the script and adds "MODAL SHOW" again
I tried to add modal.off(); in the modal script like this:
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget)
var modal = $(this)
//......
modal.off();
console.log('MODAL SHOW')
$('.date-test').datepicker();
$('.modal-body').prepend('<div><strong>MODAL SHOW</strong></div>')
});
But the problem is that if the user closes the modal and clicks on another link, it reloads the same modal as the old one (whereas it is another link with another data)
Where does the problem come from ?
How to make sure that when I click on the input, the script does not think that I am reloading the modal
Adding the following code should help with your problem.
$(".date-test").datepicker().on('show.bs.modal', function(event) {
// prevent datepicker from firing bootstrap modal "show.bs.modal"
event.stopPropagation();
That's a known bug hat has to do with bootstraps datetimepicker

I am building a table based on data returned from my API.
For each row in the table I would like to create a bootstrap modal with additional info in it.
This is how I do it right now. I created a designated div and I put all the modals inside it. Please note that in addition the modal's HTML is pretty big by itself:
let modal = `<div id="modal-${i}">big HTML here</div>`;
$("#modalsCollector").append(modal);
And this is how my table row looks like:
<tr data-toggle="modal" data-target="#modal-${i}">
Because I sometimes have 500+ table rows there is eventually a huge div (#modalsCollector) full of same (by structure) modals. I feel that it affects page performance.
Is there a better, more elegant and performance optimized way to bind modals to table rows? Or in general, working with many hidden elements instead of pushing them into the DOM that way?
You can include only one "null" modal in your <body>, like this:
<div id="myModal" class="modal fade" 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>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<button type="button" class="btn" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
Then when you have to show the modal generate it using jQuery like this:
$("#button").click(function(e){
$("#myModal .modal-header").append(HTML for modal header here);
$("#myModal .modal-body").html(big HTML for modal body here);
$("#myModal").modal("show");
});
So, basically you change the modal header and the modal body of the same modal each time, with the needed information accordingly, without the need of like thousands of modals.
Bootstrap has a neat way of changing the components of the same modal. This is as long as you need the same modal just different content inside.
https://getbootstrap.com/docs/4.5/components/modal/#varying-modal-content
Here is an example:
HTML:
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="#mdo">Open modal for #mdo</button>
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModal" data-whatever="#fta">Open modal for #fat</button>
<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">New message</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<form>
<div class="form-group">
<label for="recipient-name" class="col-form-label">Recipient:</label>
<input type="text" class="form-control" id="recipient-name">
</div>
</form>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
and jQuery:
$('#exampleModal').on('show.bs.modal', function (event) {
var button = $(event.relatedTarget) // Button that triggered the modal
var recipient = button.data('whatever') // Extract info from data-* attributes
// Update the modal's content.
var modal = $(this)
modal.find('.modal-title').text('New message to ' + recipient)
modal.find('.modal-body input').val(recipient)
})
I'm new to programming, and I have this simple question but I can't figure out how to do it.
I got this working code from Boostrap 4:
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary" data-toggle="modal" data-target="#exampleModalLong">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="exampleModalLong" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLongTitle">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>
But instead of having a button I want to create a function to fire up the modal content:
function openModal(){
/* DESCRIPTION: Open the warning modal */
// data-toggle="modal" data-target="#exampleModal"
}
But I don't know how to the same thing as data-toggle and
data-target do in the button click.
Someone has a hint how to do that?
You have to use the Bootstrap JS api for the modal ( Link attached at the end of this answer ).
Here is the straight answer :-)
function openModal(){
/* DESCRIPTION: Open the warning modal */
$('#exampleModalLong').modal('show');
}
Here is another SO question related to this : How can I trigger a Bootstrap modal programmatically?
Here is a detailed link on Bootstrap official documentation on various javascript methods for modals.
https://getbootstrap.com/docs/4.0/components/modal/#methods
Just use this line in your function:
$('#myModal').modal('show');
Note: remember to replace your modal id with myModal.
I'm trying to send data from my index page to a modal.
Here's my code.
Modal
<div class="modal modal-1 fade bd-example-modal-lg " id="exampleModalCenter" tabindex="-1" role="dialog" aria-labelledby="exampleModalLongTitle" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title subtitles" id="exampleModalLongTitle">¿Cómo funciona?</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="demo">
<!-- Here's where I want to get data -->
<input data-id="sum">
</div>
</div>
<div class="modal-footer">
<!-- <button type="button" class="btn btn-secondary" data-dismiss="modal"></button> -->
<button type="button" class="btn btn-secondary" data-dismiss="modal" data-toggle="modal" data-target="#exampleModalCenter2" >Siguiente</button>
</div>
</div>
</div>
</div>
First, my button to show my modal
<button type="button" data-toggle="modal" data-target="#exampleModalCenter" > Cotizar préstamo </button>
Input data that I want to send to my modal
<input class="c-slider__loan-sum" id="sum" name="loan_sum" type="hidden" value="NaN">
<input class="c-slider__loan-period" name="loan_period" type="hidden" value="20">
And I've been trying with this jQuery
$('#exampleModalCenter').on('click','shown.bs.modal', function () {
let a = $(this).data('id');
$(".modal-body #sum").val( a );
$('#myInput').trigger('focus');
})
If someone could help me, I'll be so grateful
I believe your argument list for .on() is incorrect. If you want to specify multiple events to trigger the handler you separate them with a comma: .on('click, shown.bs.modal', func...).
However, I think you need to remove shown.bs.modal all together, as that event is triggered after the modal has rendered.
Another issue you may have is that you're not actually getting the values from your hidden inputs in your handler. You're just, seemingly, trying to get the id of the button that's being clicked and setting that as the value on some non-existent input in your modal. If you are trying to get the id of the button (for some reason I can't see) then you can get it like this const id = $('#buttonId').attr('id');. What you're doing is trying to get the value from a data attribute that doesn't exist on the button element: ...').data('id');.
Check out this simple example to see how you may want to handle this: https://codepen.io/dustinoverby/pen/NExXMb?editors=1010
I'm creating a type of content management system that allows users to create pages based on templates.
I have a page that has 2 placeholder divs. Below is an example of one. When you click on the div, a modal pops up that allows the user to use TinyMCE to create content. The idea is to set the content, hit the "Get Data" button and have the modal disappear with the content from the editor now displaying inside the original div.
This is working as far as p utting the content in the div when I hit submit. The body of the modal disappears at this point, but the gray opacity screen that usually sits under the bootstrap modal is still present and I can't any longer do anything on the page. I'm wondering what I'm doing wrong here and how I can fix it to fully close the modal when I hit the submit button.
<div class="leftContent">
<div class="modal fade bd-example-modal-lg" id="leftFiftyModal" tabindex="-1" role="dialog" aria-labelledby="leftFiftyLabel" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="leftFiftyModal">Content Library:</h5>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<h3>Create your own content</h3>
<form id="form-data" method="post">
<textarea id="mytextarea"></textarea>
<input type="submit" value="Get Data">
</form>
</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>
<script type="text/javascript">
$(document).ready(function(){
$("#form-data").submit(function(e){
var content = tinymce.get("mytextarea").getContent();
$(".leftContent").html(content);
return false;
});
jQuery.noConflict();
$('#leftFiftyModal').modal('hide');
});
</script>
Try:
<script type="text/javascript">
$(document).ready(function(){
$("#form-data").submit(function(e){
var content = tinymce.get("mytextarea").getContent();
$(".leftContent").html(content);
jQuery.noConflict();
$('#leftFiftyModal').modal('hide');
return false;
});
});
</script>
