Javascript not triggering on modal open with Twig Template - javascript

Note: I've tried the various solutions found online for my issue, but none of them have worked.
I am trying to pass content from a table where each row has its own button to edit the content in that row. The button opens a Twitter Bootstrap dropdown, which has two buttons, one being the "Edit" button. The edit button opens a modal which has a text-area input. I want the text-area to have the current text present in the table for editing. I am using PHP with Symfony for the forms and Twig for the page rendering.
the button that triggers the modal
<div class="dropdown-menu" aria-labelledby="dropdownMenuButton">
<button class="btn btn-sm dropdown-item edit-button" data-toggle="modal" data-target="#announcementEditModal" data-id="{{ announcement.id }}" data-content="{{ announcement.content }}" type="button">
<div class="announcement-actions">
<span class="fas fa-pencil-alt"></span> Edit announcement
</div>
</button>
The modal
<div class="modal fade" id="announcementEditModal" tabindex="-1" role="dialog" aria-hidden="true">
<div class="modal-dialog modal-lg" role="document">
<div class="modal-content">
<div class="modal-header announcement-header">
<h5 class="modal-title" id="exampleModalLabel"><span class="fas fa-edit"></span> Edit new announcement</h5>
</div>
<div class="announcement-card-header card m-3 border-0">
<div class="announcement-card-header card-body border-0 p-1">
<span class="fa fa-info-circle fa-lg header-icon"></span>
<h5 class="align-header">ANNOUNCEMENT TEXT</h5>
</div>
<div class="announcement-card-body modal-body card border-0">
{{ form_start(editForm) }}
<div class="announcement-card-body">
<label for="exampleInputEmail1">ANNOUNCEMENT (SUPPORTS MARKDOWN)</label>
<textarea class="form-control" id="announcementText" rows="5" name="content"></textarea>
</div>
</div>
</div>
<div class="card-footer border-0 bg-white pt-0">
<div>
{{ form_widget(editForm.edit, {'left_icon': 'fas fa-check'}) }}
<button type="button" class="btn btn-light" data-dismiss="modal" aria-label="Close">
Cancel
</button>
</div>
</div>
{{ form_end(editForm) }}
</div>
</div>
</div>
The JavaScript
<script type="text/javascript">
$(".edit-button").click(function(){
var content = $(this).data("content");
alert(content);
});
$('#announcementEditModal').on('shown.bs.modal', function () {
alert("modal open");
document.getElementById("#announcementText").val(content);
})
</script>
The alert("modal open") does not fire.I have tried'shown.bs.modal'and'show.bs.modal'`. I'm using Bootstrap 4.12
EDIT: Solution: Once I moved the JS to an announcements.js file where I was doing some stuff with my forms the trigger works.

It appears you either have an incomplete html code or have not shared it all with us.
dropdown-menu does not have a closing div.
wrap dropdown-menu inside dropdown or btn-group.
var content will not be available inside your shown.bs.modal function, so declare it globally, not a very good advice but for simplicity sake.
Fix Javascript error, since you are using jQuery, use it.
document.getElementById("#announcementText").val(content); // val is not function
Replace with
document.getElementById("#announcementText").value = content;
$("#announcementText").val(content); // or jQuery way
And here is the fiddle: https://jsfiddle.net/7onyuw9f/1/
Attempt 2
Below is an example of revealing module pattern to show how you can avoid global variables and also a lot cleaner. You can read more about this pattern here
// Revealing Module Pattern
var MyProject = MyProject || {}; // Your global object
MyProject.Modal = function() { // Namespacing to Modal
var content = ""; // now content is local to this function;
var onEditClick = function() {
$(".edit-button").click(function() {
content = $(this).data("content");
alert(content);
});
};
var onModalShow = function() {
$('#announcementEditModal').on('shown.bs.modal', function() {
alert("modal open");
// $("#announcementText").val(content); <-- jQuery way
document.getElementById("announcementText").value = content;
});
};
var init = function() {
onEditClick();
onModalShow();
};
return {
init: init // expose this for other functions to call
}
}();
$(document).ready(function() {
MyProject.Modal.init();
});

Converting Bootstrap 3 remote modal to Bootstrap 4 modal with parameters

So in the near future my shop is going to upgrade to Bootstrap 4 but we cannot do this until we solve the issue with using remote modals. Here is an example of how we load our modals. The reason we use remote modals is because the modal-body is dynamic and may use different file based on the url. I have heard that using jQuery("#newsModal").on("load",..) is an alternative but how could I do this? I found this but I am not sure how my anchor would look and how to build the url to load the remote data.
Global PHP include file:
<div id="NewsModal" class="modal fade" tabindex="-1" role="dialog" data-
ajaxload="true" aria-labelledby="newsLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal" aria-hidden="true">×</button>
<h3 class="newsLabel"></h3>
</div>
<div class="noscroll-modal-body">
<div class="loading">
<span class="caption">Loading...</span>
<img src="/images/loading.gif" alt="loading">
</div>
</div>
<div class="modal-footer caption">
<button class="btn btn-right default modal-close" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
modal_news.php file:
<form id="newsForm">
<div id="hth_err_msg" class="alert alert-danger display-hide col-lg-12 col-md-12 col-sm-12 col-xs-12">
You have some errors. Please check below.
</div>
<div id="hth_ok_msg" class="alert alert-success display-hide col-lg-12 col-md-12 col-sm-12 col-xs-12">
✔ Ready
</div>
<!-- details //-->
</form>
Here is how we trigger the modals :
<a href="#newsModal" id="modal_sbmt" data-toggle="modal" data-target="#newsModal"
onclick="remote='modal_news.php?USER=yardpenalty&PKEY=54&FUNCTION=*GENERAL'; remote_target='#NewsModal .noscroll-modal-body'">
<span class="label label-icon label-info">
<i class="fa fa-bullhorn"></i>
</span>
Promotional Ordering
</a>
I think I need to do something like this when building anchor dynamically:
a) Replace paramters with data-attrs
b) Use the event invoker to get the data-attrs using event.target.id
Thanks to Tieson T. and this post I was able to effectively pass parameters to the remote modal using this technique except if you have multiple modals
I have also included some helpful techniques inside this example as to how you may pass parameters to the remote modal.

$(".add-attendee").addClass("hidden");
$("#signupForm input[type='hidden']").remove();
});
// BOOTSTRAP 4 REMOTE MODAL ALTERNATIVE FOR BOOTSTRAP 3v-

<script>
$(document).ready(function(){
console.log('<?php echo $_GET["USERNAME"]?>'); //passed through url
});
</script>
NOTE: I am having problems with event propagation during the show.bs.modal event which I have a global show.bs.modal that is propagating up to this event handler due to multiple modals so if you have multiple modals make sure to handle them correctly.
Here is a screen shot of the results which clearly show propagation is taking place but the parameter passing techniques are working.
You might find it easier to use something like Bootbox.js, which can be used to dynamically create Bootstrap modals.
Given what you've shown, it would work something like:
trigger modal
with
$(function(){
$('.show-modal').on('click', function(e){
e.preventDefault();
var url = $(this).attr('href');
$.get(url)
.done(function(response, status, jqxhr) {
bootbox.dialog({
title: 'Your Title Here',
message: response
});
});
});
});
This assumes response is an HTML fragment.
Bootbox hasn't officially been confirmed to work with Bootstrap 4, but I haven't run into any problems with it yet (modals seem to be one of the few components that don't have updated markup in BS4).
Disclaimer: I am currently a contributor to Bootbox (mainly updating the documentation and triaging issues).
If you must use only the Bootstrap modal, you're actually after load(). You would probably do something like:
$(function(){
$('.show-modal').on('click', function(e){
e.preventDefault();
var url = $(this).attr('href');
var dialog = $('#NewsModal').clone();
dialog.load(url, function(){
dialog.modal('show');
});
});
});

How to capture a button click event from a different page in a different View and make DOM manipulation in the source page?

I have the following html construct in the source Page View:
<i id="asterisk" class="fa fa-asterisk show asterisk" ></i>
<a id="tos" data-toggle="modal" data-target="#divTermsAndConditions" href="#Url.Action("TermsOfServiceFromRegistration", "Account", new { lk = ViewBag.LicenseKey })" target="_blank">
<div>
<div class="modal fade" id="divTAndC" role="dialog" data-backdrop="static" data-keyboard="false" aria-describedby="termsandconditions" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-body">
#if (ViewData.ModelState.IsValid && fetchTOSAction) {
{ Html.RenderAction("TermsOfServiceFromRegistration", "Account", new { lk = ViewBag.LicenseKey }); }
}
</div>
</div>
</div>
</div>
And the new View which it opens, has a button:
<button class="btn btn-primary" id="btnClose" data-dismiss="modal">Close</button>
As you can see, it is a bootstrap button and on clicking of it, it closes the current window:"TermsofService.cshtml".
Now, my requirement is like this:
1.Capture this button click event
2.And on that event make some DOM manipulation in the source View, like :
$("#asterisk").removeClass("show").addClass("hide");
Is it possible?
Any help will be highly appretiated.
Thanks in advance.
Solved it myself!Bingo!
Here it is:
$("#divTAndC").on("hidden.bs.modal", function () {
$("#check").removeClass("hide").addClass("show");
});
Basically, in the source view itself,bind the function on modal close.
Thats it!

bootstrap modal not showing

We are currently stuck using bootstrap 2.3.2, and are looking to replace our current dialogs with bootstrap's modals.
I've located all the views where modals need to be instantiated and attempted 2 ways to call them without success.
With JS:
Html:
<a title='New Group' class='btn btn-fancy' id="btn-new-group" data-bind="visible: Value() == 'CanCreateNewGroup', click: corp.page.CreateGroupDialog.show">New Group<i class="fa fa-fw fa-lg fa-users"></i></a>
JS:
define([
'app-utils',
'jquery',
'bootstrap'
], function (utils) {
var CreateGroupDialog = function () {
};
CreateGroupDialog.prototype = $.extend(true, CreateGroupDialog.prototype, {
show: function (model) {
var dialog = $('#testing-bootstrap').modal({
toggle: true,
show: true,
keyboard: true
});
}
});
return CreateGroupDialog;
});
Without JS:
Html:
<a data-target="#testing-bootstrap" data-toggle="modal" class="btn btn-simple show_tooltip" title="Create Group"><i class="fa fa-fw fa-plus-circle"></i><span>Create Group</span></a>
The reason why I have to come here is that I get NO console errors, NO clue. The JS in my example is being hit, bootstrap is included and I've stepped through bootstrap code and it is loading my modal's html, but it is not coming up on the screen in EITHER way, with no console errors.
Actual modal markup (from bootstrap's example)
<div id="testing-bootstrap" 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>
Thanks, everyone.
I'm not totally sure how the binding is working in your example - it appears to use the Knockout data-bind attribute, but the rest is jQuery. I'm guessing that your CreateGroupDialog is not being correctly bound to the modal HTML - especially since you are using require.js. If the HTML without JS does not work either, there could be something else wrong, but I would modify your constructor code to bind to your <a> that should trigger the modal.
var CreateGroupDialog = function () {
$( 'a[title="Create Group"]' ).click( $.proxy( this.show, this ) );
};
Then instantiate it:
var modal = new CreateGroupDialog;
The suspected html in the description area of this question was part of an HTML partial which was being called in an area of the application that was not going to be visible then.
If you are using html partials then look into their visibility before doubting the bootstrap modals. That was my problem.

Reload content in modal (twitter bootstrap)

I'm using twitter bootstrap's modal popup.
<div id="myModal" class="modal hide fade in">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Header</h3>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<input type="submit" class="btn btn-success" value="Save"/>
</div>
</div>
I can load content using ajax with this a-element:
<a data-toggle="modal" data-target="#myModal" href="edit.aspx">Open modal</a>
Now I have to open the same modal but using a different url. I'm using this modal to edit an entity from my database. So when I click edit on an entity I need to load the modal with an ID.
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=1">Open modal</a>
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=2">Open modal</a>
<a data-toggle="modal" data-target="#myModal" href="edit.aspx?id=3">Open modal</a>
If I click on link number 1, it works fine. But if I then click on link number 2 the modal content is already loaded and therefor it will show the content from link number 1.
How can I refresh or reset the ajax loaded content in a twitter bootstrap modal popup?
I guess the way of doing this will be to remove the data-toggle attribute and have a custom handler for the links.
Something in the lines of:
$("a[data-target=#myModal]").click(function(ev) {
ev.preventDefault();
var target = $(this).attr("href");
// load the url and show modal on success
$("#myModal .modal-body").load(target, function() {
$("#myModal").modal("show");
});
});
To unload the data when the modal is closed you can use this with Bootstrap 2.x:
$('#myModal').on('hidden', function() {
$(this).removeData('modal');
});
And in Bootstrap 3 (https://github.com/twbs/bootstrap/pull/7935#issuecomment-18513516):
$(document.body).on('hidden.bs.modal', function () {
$('#myModal').removeData('bs.modal')
});
//Edit SL: more universal
$(document).on('hidden.bs.modal', function (e) {
$(e.target).removeData('bs.modal');
});
You can force Modal to refresh the popup by adding this line at the end of the hide method of the Modal plugin (If you are using bootstrap-transition.js v2.1.1, it should be at line 836)
this.$element.removeData()
Or with an event listener
$('#modal').on('hidden', function() {
$(this).data('modal').$element.removeData();
})
With Bootstrap 3 you can use 'hidden.bs.modal' event handler to delete any modal-related data, forcing the popup to reload next time:
$('#modal').on('hidden.bs.modal', function() {
$(this).removeData('bs.modal');
});
Based on other answers (thanks everyone).
I needed to adjust the code to work, as simply calling .html wiped the whole content out and the modal would not load with any content after i did it. So i simply looked for the content area of the modal and applied the resetting of the HTML there.
$(document).on('hidden.bs.modal', function (e) {
var target = $(e.target);
target.removeData('bs.modal')
.find(".modal-content").html('');
});
Still may go with the accepted answer as i am getting some ugly jump just before the modal loads as the control is with Bootstrap.
A little more compressed than the above accepted example. Grabs the target from the data-target of the current clicked anything with data-toggle=modal on. This makes it so you don't have to know what the id of the target modal is, just reuse the same one! less code = win! You could also modify this to load title, labels and buttons for your modal should you want to.
$("[data-toggle=modal]").click(function(ev) {
ev.preventDefault();
// load the url and show modal on success
$( $(this).attr('data-target') + " .modal-body").load($(this).attr("href"), function() {
$($(this).attr('data-target')).modal("show");
});
});
Example Links:
<a data-toggle="modal" href="/page/api?package=herp" data-target="#modal">click me</a>
<a data-toggle="modal" href="/page/api?package=derp" data-target="#modal">click me2</a>
<a data-toggle="modal" href="/page/api?package=merp" data-target="#modal">click me3</a>
I made a small change to Softlion answer, so all my modals won't refresh on hide.
The modals with data-refresh='true' attribute are only refreshed, others work as usual.
Here is the modified version.
$(document).on('hidden.bs.modal', function (e) {
if ($(e.target).attr('data-refresh') == 'true') {
// Remove modal data
$(e.target).removeData('bs.modal');
// Empty the HTML of modal
$(e.target).html('');
}
});
Now use the attribute as shown below,
<div class="modal fade" data-refresh="true" id="#modal" tabindex="-1" role="dialog" aria-labelledby="#modal-label" aria-hidden="true"></div>
This will make sure only the modals with data-refresh='true' are refreshed. And i'm also resetting the modal html because the old values are shown until new ones get loaded, making html empty fixes that one.
Here is a coffeescript version that worked for me.
$(document).on 'hidden.bs.modal', (e) ->
target = $(e.target)
target.removeData('bs.modal').find(".modal-content").html('')
It will works for all version of twitterbootstrap
Javascript code :
<script type="text/javascript">
/* <![CDATA[ */
(function(){
var bsModal = null;
$("[data-toggle=modal]").click(function(e) {
e.preventDefault();
var trgId = $(this).attr('data-target');
if ( bsModal == null )
bsModal = $(trgId).modal;
$.fn.bsModal = bsModal;
$(trgId + " .modal-body").load($(this).attr("href"));
$(trgId).bsModal('show');
});
})();
/* <![CDATA[ */
</script>
links to modal are
<a data-toggle="modal" data-target="#myModal" href="edit1.aspx">Open modal 1</a>
<a data-toggle="modal" data-target="#myModal" href="edit2.aspx">Open modal 2</a>
<a data-toggle="modal" data-target="#myModal" href="edit3.aspx">Open modal 3</a>
pop up modal
<div id="myModal" class="modal hide fade in">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Header</h3>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<input type="submit" class="btn btn-success" value="Save"/>
</div>
I was also stuck on this problem then I saw that the ids of the modal are the same. You need different ids of modals if you want multiple modals. I used dynamic id. Here is my code in haml:
.modal.hide.fade{"id"=> discount.id,"aria-hidden" => "true", "aria-labelledby" => "myModalLabel", :role => "dialog", :tabindex => "-1"}
you can do this
<div id="<%= some.id %>" class="modal hide fade in">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Header</h3>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<input type="submit" class="btn btn-success" value="Save" />
</div>
</div>
and your links to modal will be
<a data-toggle="modal" data-target="#" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>
<a data-toggle="modal" data-target="#myModal" href='"#"+<%= some.id %>' >Open modal</a>
I hope this will work for you.
You can try this:
$('#modal').on('hidden.bs.modal', function() {
$(this).removeData('bs.modal');
});
I wanted the AJAX loaded content removed when the modal closed, so I adjusted the line suggested by others (coffeescript syntax):
$('#my-modal').on 'hidden.bs.modal', (event) ->
$(this).removeData('bs.modal').children().remove()
var $table = $('#myTable2');
$table.bootstrapTable('destroy');
Worked for me
step 1 : Create a wrapper for the modal called clone-modal-wrapper.
step 2 : Create a blank div called modal-wrapper.
Step 3 : Copy the modal element from clone-modal-wrapper to modal-wrapper.
step 4 : Toggle the modal of modal-wrapper.
<a data-toggle="modal" class='my-modal'>Open modal</a>
<div class="clone-modal-wrapper">
<div class='my-modal' class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<a class="close" data-dismiss="modal">×</a>
<h3>Header</h3>
</div>
<div class="modal-body"></div>
<div class="modal-footer">
<input type="submit" class="btn btn-success" value="Save"/>
</div>
</div>
</div>
</div>
</div>
<div class="modal-wrapper"></div>
$("a[data-target=#myModal]").click(function (e) {
e.preventDefault();
$(".modal-wrapper").html($(".clone-modal-wrapper").html());
$('.modal-wrapper').find('.my-modal').modal('toggle');
});

How can I trigger a Bootstrap modal programmatically?

If I go here
http://getbootstrap.com/2.3.2/javascript.html#modals
And click 'Launch demo modal' it does the expected thing. I'm using the modal as part of my signup process and there is server side validation involved. If there are problems I want to redirect the user to the same modal with my validation messages displayed. At the moment I can't figure out how to get the modal to display other than a physical click from the user. How can I launch the model programmatically?
In order to manually show the modal pop up you have to do this
$('#myModal').modal('show');
You previously need to initialize it with show: false so it won't show until you manually do it.
$('#myModal').modal({ show: false})
Where myModal is the id of the modal container.
You should't write data-toggle="modal" in the element which triggered the modal (like a button), and you manually can show the modal with:
$('#myModal').modal('show');
and hide with:
$('#myModal').modal('hide');
This is a code for Bootstrap v5 without jQuery.
let myModal = new bootstrap.Modal(document.getElementById('myModal'), {});
myModal.show();
Demo
And this is a codesandbox demo to open modal on page load programmatically.

If you are looking for a programmatical modal creation, you might love this:
http://nakupanda.github.io/bootstrap3-dialog/
Even though Bootstrap's modal provides a javascript way for modal creation, you still need to write modal's html markups first.
HTML
<!-- Button trigger modal -->
<button type="button" class="btn btn-primary btn-lg">
Launch demo modal
</button>
<!-- Modal -->
<div class="modal fade" id="myModal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">

</div>
</div>
</div>
</div>
JS
$('button').click(function(){
$('#myModal').modal('show');
});
DEMO JSFIDDLE
you can show the model via jquery (javascript)
$('#yourModalID').modal({
show: true
})
Demo: here
or you can just remove the class "hide"
<div class="modal" id="yourModalID">
# modal content
</div>

I wanted to do this the angular (2/4) way, here is what I did:
<div [class.show]="visible" [class.in]="visible" class="modal fade" id="confirm-dialog-modal" role="dialog">
..
</div>`
Important things to note:
visible is a variable (boolean) in the component which governs modal's visibility.
show and in are bootstrap classes.
An example component & html
Component
#ViewChild('rsvpModal', { static: false }) rsvpModal: ElementRef;
..
#HostListener('document:keydown.escape', ['$event'])
onEscapeKey(event: KeyboardEvent) {
this.hideRsvpModal();
}
..
hideRsvpModal(event?: Event) {
if (!event || (event.target as Element).classList.contains('modal')) {
this.renderer.setStyle(this.rsvpModal.nativeElement, 'display', 'none');
this.renderer.removeClass(this.rsvpModal.nativeElement, 'show');
this.renderer.addClass(document.body, 'modal-open');
}
}
showRsvpModal() {
this.renderer.setStyle(this.rsvpModal.nativeElement, 'display', 'block');
this.renderer.addClass(this.rsvpModal.nativeElement, 'show');
this.renderer.removeClass(document.body, 'modal-open');
}
Html
<!--S:RSVP-->
<div class="modal fade" #rsvpModal role="dialog" aria-labelledby="niviteRsvpModalTitle" (click)="hideRsvpModal($event)">
<div class="modal-dialog modal-dialog-centered modal-dialog-scrollable" role="document">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="niviteRsvpModalTitle">
</h5>
<button type="button" class="close" (click)="hideRsvpModal()" 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 bg-white text-dark"
(click)="hideRsvpModal()">Close</button>
</div>
</div>
</div>
</div>

The following code useful to open modal on openModal() function and close on closeModal() :
function openModal() {
$(document).ready(function(){
$("#myModal").modal();
});
}
function closeModal () {
$(document).ready(function(){
$("#myModal").modal('hide');
});
}
/* #myModal is the id of modal popup */
The same thing happened to me. I wanted to open the Bootstrap modal by clicking on the table rows and get more details about each row. I used a trick to do this, Which I call the virtual button! Compatible with the latest version of Bootstrap (v5.0.0-alpha2). It might be useful for others as well.
See this code snippet with preview:
https://gist.github.com/alireza-rezaee/c60da1429c36351ef4f071dec0ea9aba
Summary:
let exampleButton = document.createElement("button");
exampleButton.classList.add("d-none");
document.body.appendChild(exampleButton);
exampleButton.dataset.toggle = "modal";
exampleButton.dataset.target = "#exampleModal";
//AddEventListener to all rows
document.querySelectorAll('#exampleTable tr').forEach(row => {
row.addEventListener('click', e => {
//Set parameteres (clone row dataset)
exampleButton.dataset.whatever = e.target.closest('tr').dataset.whatever;
//Button click simulation
//Now we can use relatedTarget
exampleButton.click();
})
});
All this is to use the relatedTarget property. (See Bootstrap docs)
Here's how you do it with ternary operator
$('#myModal').modal( variable === 'someString' ? 'show' : 'hide');
