How to create a click-function in a modal

Hey I am new to js and I was trying to open a bootstrap modal with a click on a button (I set the id to the value of the button because the id comes from a database) and if you click on "yes" in that modal a click function should be triggered which should then delete the selected row.
I am able to open the modal and setting the id also works but if I click the yes button in the modal there is no alert...
This is the modal located in content.html:
<!--Delete Modal-->
<div class="modal fade" id="deleteModal" tabindex="-1" role="dialog" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog" role="document">
<div class="modal-content">
<div class="modal-header">
<h3 class="modal-title" id="exampleModalLabel">Return Device</h3>
<button type="button" class="close" data-dismiss="modal" aria-label="Close">
<span aria-hidden="true">×</span>
</button>
</div>
<div class="modal-body">
<div class="container">
<div class="row">
<div class="col">
<p><b> Are you sure you want to return this device? </b></p>
Please make sure you return the device.
</div>
</div>
</div>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-dismiss="modal">No</button>
<button type="button" class="btn btn-primary delBtn" data-dismiss="modal">Yes</button>
</div>
</div>
</div>
</div>
This is my JS located in main.js:
$(document).ready(function () {
$('#myModal').on('shown.bs.modal', function () {
$('#myInput').trigger('focus');
});
$('#booked').click(function () {
$('#changestuff').load('content.html #booked', function () {
register();
change();
$('.ret').click(function () {
var id = $(this).val();
var tr = $(this).closest('tr');
})
returnOne(id, tr);
});
$('#booked').addClass('active');
$('#book').removeClass('active');
$('#admin').removeClass('active');
});
});
function returnOne(id, tr)
{
$('.delBtn').click(function () {
alert("you returned" +id);
})
}
Where is my error? I think it might be because the modal hasn't been loaded when I try to get the click event but I'm not sure. Thanks in advance!

click event handler is not attaching may be it is getting called before yes button dom get created.
Try below code where you can store row to be deleted in a variable and set row-id data attribute on Yes button. In click handler of Yes button, read the id and you can delete row from variable rowToDelete
$(document).ready(function(){
var rowToDelete;
$('#myModal').on('shown.bs.modal', function(){
$('#myInput').trigger('focus');
});
/*$('#changestuff').load('content.html #book', function(){
register();
change();
getChosenDevices();
});*/
$('#changestuff').on('load','content.html #book', function(){
register();
change();
getChosenDevices();
});
$('#booked').click(function() {
$('#booked').addClass('active');
$('#book').removeClass('active');
$('#admin').removeClass('active');
});
$(document).on('click','.ret',function() {
var id = $(this).val();
$('#deleteModal .delBtn').data('row-id', id); //set data id
rowToDelete = $(this).closest('tr'); //store row in variable
});
$(document).on("click", '#deleteModal button.delBtn', function(e) {
e.preventDefault();
var rowId = $(this).data('row-id');
alert("you returned" + rowId);
$('#deleteModal').modal('toggle');
});
});

Boostrap modal not loading when wired using jquery

I have the following link and I'm trying to load a bootstrap modal when its clicked but the javascript function doesnt seem to be firing. Instead of the view loading inside a modal, its loading as a new page?
#*this is the modal definition*#
<div class="modal hide fade in" id="report-summary">
<div id="report-summary-container"></div>
</div>
<script >
$('a.js-report-summary').click(function (e) {
var url = $(this).attr('href'); // the url to the controller
e.preventDefault();
$.get(url, function (data) {
$('#report-summary-container').html(data);
$('#report-summary').modal('show');
});
});
</script>
public ActionResult ReportSummary()
{
// some actions
return PartialView("ReportSummary", viewmodel)
}
// Report summary view which contains 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 class="modal-title" id="myModalLabel">#ViewBag.FormName - Analysis</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-primary" data-dismiss="modal">
Close</button>
</div>
</div>
</div>
There are no errors showing in the console either so why isn't the jquery function firing?

in your click function, add parameter e this will stand for event
then in the function itself add e.preventDefault() This will stop the refreshing effect.

on your controller method try
public ViewResult ReportSummary()
{
// some actions
if(Request.IsAjaxRequest())
return PartialView("ReportSummary", viewmodel);
else
return View("ReportSummary", viewmodel);
}
on your view
$('#exampleModal').on('show.bs.modal', function (event) {//give your model wrapper an id
//do some ajax and get html
$.ajax({
url:'',
success:function(data){
$('#report-summary-container').html(data);
}
});
})
on your anchor tag, add data-toggle="modal" data-target="#exampleModal"
if you dont want to use bootstrap events trigger your modal with
$('#myModal').modal('show')

What closed the modal?

I am using a twitter bootsrap modal. It contains the buttons "Save", "Cancel" and the arrow for closing. How do handle the case (and recognize it) when the modal is closed by the arrow and when by a button?
$("#myModal).on('hidden.bs.modal', function () {
// ??? Arrow or button is the initiator
});

You need to hook into the button/icon clicks yourself and dismiss the modal from javascript. Here is an example:
$(function () {
var myModal = $("#myModal");
$("#btnShow").on("click", function () {
myModal.modal("show");
});
myModal.find(".closeIcon").on("click", function () {
console.log("Close Icon clicked.");
myModal.trigger("myModal.dismiss.closeIcon");
myModal.modal("hide");
}).end().find(".closeButton").on("click", function () {
console.log("Close Button clicked.");
myModal.trigger("myModal.dismiss.closeButton");
myModal.modal("hide");
}).end().find(".saveButton").on("click", function () {
console.log("Save Button clicked.");
myModal.trigger("myModal.dismiss.saveButton");
myModal.modal("hide");
});
myModal.on("myModal.dismiss.closeIcon", function () {
console.log("Close Icon Handler called.");
}).on("myModal.dismiss.closeButton", function () {
console.log("Close Button Handler called.");
}).on("myModal.dismiss.saveButton", function () {
console.log("Save Button Handler called.");
});
});
Basic Modal HTML (with classes for closeIcon, closeButton, and saveButton added to be able to dispatch the events).
<button id="btnShow">Show Modal</button>
<div id="myModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close closeIcon" aria-hidden="true">×</button>
<h4 class="modal-title">Modal title</h4>
</div>
<div class="modal-body">
<p>One fine body…</p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default closeButton" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary saveButton">Save changes</button>
</div>
</div><!-- /.modal-content -->
</div><!-- /.modal-dialog -->
</div><!-- /.modal -->
jsfiddle here.

Its not possible to track event while closing the modal with data-toggles like data-dismiss="modal".
Try to use the events on each of them to get resolved.

Open a bootstrap modal from another page

I have a list of links that each open their own modal. Each of these modals contents display an html file. Here is a sample;
<div id="how-rtm-works" class="modal hide fade" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
<h1 id="myModalLabel">How Right to Manage works</h1>
</div>
<div class="modal-body" id="utility_body">
<p>One fine body…this is getting replaced with content that comes from passed-in href</p>
</div>
<div class="modal-footer">
<button class="btn" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
<li><a data-target="#how-rtm-works" href="modal-content/how-RTM-works.html" role="button" data-toggle="modal">How Right to Manage works</a></li>
Because there is more than one modal, each has its own ID which is referenced in the data-target.
Can anyone advise me on how I would target these modals from another page, or in my case all pages as these will be linked in the website footer nav.

First page you'll use:
Open Modal
At the second page you'll insert your modal and the follow script:
<script type='text/javascript'>
(function() {
'use strict';
function remoteModal(idModal){
var vm = this;
vm.modal = $(idModal);
if( vm.modal.length == 0 ) {
return false;
}
if( window.location.hash == idModal ){
openModal();
}
var services = {
open: openModal,
close: closeModal
};
return services;
///////////////
// method to open modal
function openModal(){
vm.modal.modal('show');
}
// method to close modal
function closeModal(){
vm.modal.modal('hide');
}
}
Window.prototype.remoteModal = remoteModal;
})();
$(function(){
window.remoteModal('#myModalLabel');
});
</script>

Well your modals had IDs, I think you can trigger them by adding #how-rtm-works to the end of the link
for example if you have a modal called
id="My_Modal"
you can make a link
Link me to the modal
If that is your question I guess this can help you out !

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.

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 class="modal-dialog">
<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">Modal title</h4>
</div>
<div class="modal-body">
...
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
<button type="button" class="btn btn-primary">Save changes</button>
</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">

<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>

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');
