Set element offset relative to bootstrap modal - javascript

I did some research through google and I didn't found anything useful.
It's now based by all page offset, but I need that it to be based by modal offset...
Image of page
How it supposed to be
My CSS code:
.bbox {
cursor: pointer;
border-style: dashed;
border-color: red;
background-color: transparent;
position: absolute;
}
My HTML code:
<div class="modal fade" tabindex="-1" role="dialog" id="correctionModal" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-body">
<div id="limit" style="position: relative;width: 100%; height: auto">
<img src="#" id="output-image" class="img-fluid">
<div class="bbox" id="eye_1" style="width: 20px; height: 20px;"></div>
<div class="bbox" id="eye_2" style="width: 20px; height: 20px;"></div>
</div>
<br>
<div class="form-group">
<button type="button" class="btn btn-success btn-sm" id="confirmCorrections">Patvirtinti</button>
</div>
</div>
</div>
</div>
</div>
My JS code:
var x_L = x - w_L/2;
var y_L = y - h_L/2;
$("#eye_1").height(h_L).width(w_L);
$("#eye_1").offset({ top: y_L.toFixed(2), left: x_L.toFixed(2) });


You need to add the offset of your eye boxes onto the offset of their parent element.
Something like this:
var x_L = x - w_L/2;
var y_L = y - h_L/2;
x_L += $("#limit").offset().left;
y_L += $("#limit").offset().top;
$("#eye_1").height(h_L).width(w_L);
$("#eye_1").offset({ top: y_L.toFixed(2), left: x_L.toFixed(2) });

Modal does not close, when clicked

So I have a menu, where models pop-up on click. In each model, there's a close button, marked by an "x". Only problem is, that the model does not close, when the "x" is clicked.
I have tried multiple ways of filing this seemingly simple problem. But with no luck.
I have tried, using a z-index property, I have tried fiddling with the divs. I have tried to link to bootstrap external links. I have tried different kind of "close" button. I have tried to modifying the javascript code. Still I have not arrived at the desired outcome. Can anyone help ?
Here's my code
window.onload = function () {
list = document.querySelectorAll(".Project");
for (let i = 0; i < list.length; i++) {
list[i].addEventListener("click", function (e) {
e.preventDefault();
let currentElement = e.target.parentNode;
let modalId = currentElement.dataset.modal;
let modal = document.getElementById(modalId);
modal.style.display = "block";
});
}
};
.modal {
display: none;
position: fixed;
z-index: 1;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgb(0,0,0);
background-color: rgba(0,0,0,0.4);
}
.modal-content {
background-color: #fefefe;
margin: 15% auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}

It is very easy to use modal in Bootstrap.
You just have to make sure that, as in the example below, jquery.js, popper.js and bootstrap.js are placed in order.

this is because you have a bad use of JS event delegation.
the corect way is tu use the matches method https://developer.mozilla.org/en-US/docs/Web/API/Element/matches
like this :
window.onload = function () {
list = document.querySelectorAll(".Project");
document.querySelectorAll(".Project").forEach(LIelm=>{
LIelm.addEventListener('click', showHideModal)
})
};
function showHideModal(e) {
if (!e.target.parentNode.matches('.Project , .modal-content' )) return
e.preventDefault();
let currentParent = e.target.parentNode;
if (currentParent.matches('.Project') ){
document.getElementById( currentParent.dataset.modal ).style.display = "block";
}
else {
currentParent.parentNode.style.display = "";
}
}
.modal {
display: none;
position: fixed;
z-index: 1;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgb(0,0,0);
background-color: rgba(0,0,0,0.4);
}
.modal-content {
background-color: #fefefe;
margin: 15% auto;
padding: 20px;
border: 1px solid #888;
width: 80%;
}
.close {
color: #aaa;
float: right;
font-size: 28px;
font-weight: bold;
}
.close:hover,
.close:focus {
color: black;
text-decoration: none;
cursor: pointer;
}

In Safari the center of the 3D Carousel is not right, Edge, Chrome is working fine

I'm using the Guid here: https://www.sitepoint.com/building-3d-rotating-carousel-css-javascript/, it works fine but not in safari. I try to find out what Safari does different to other Browser in this case. I guess a certain Math function like: theta = 2 * Math.PI / numImages,in Safari creates another reference to find a center in 3D space, z axis.
I can't really dig much deeper myself. I should try to move the object bit more far from Screen on z axis

here is a codepen: https://codepen.io/scribbi/pen/ZPRzrp
it should look like this:
But it looks like that:
As we can see here: http://thenewcode.com/736/Advanced-CSS-3D-Carousel the problem already exists, Safari "displaces the transform-origin-z coordinate for the gallery, pushing it forward in the browser"
for some reason it is rotating around the center of the fifth Image, while the first image is positioned deeper in the carousel.
Another approach here: https://codepen.io/scribbi/pen/BEjJLY is functioning in these Browsers, no SCSS is used and more hardcoding needed. As well it's not yet responsive.

jQuery toggle expand divs inside bootstrap container wrap

Guys basically there will be a bootstrap container div, and inside there will be 4 card style divs with toggle expand/retract button. When you click on one card's button, the div will expand all the way to the container's width. Please check the image. I'm a newbie to jQuery and with the script I've, i'm not able to achieve the full width. If someone can help me out it'll be great. Here's the code below -
$(document).ready(function() {
$('#toggle-button').click(function() {
var toggleWidth = $("#exp_card_1").width() == 600 ? "200px" : "600px";
$('#exp_card_1').animate({
width: toggleWidth
});
});
});
#exp_card_1 {
position: relative;
height: 310px;
background: #2d3644;
z-index: 1;
}
#toggle-button {
position: absolute;
right: 0;
top: 43.7%;
height: 38px;
width: 38px;
background: #131f34 url("../images/arrow.png") no-repeat;
background-position: 5px 9px;
border-radius: 3px 0 0 3px;
cursor: pointer;
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.0.3/jquery.min.js"></script>
<div class="container" style="padding:0; position:relative;">
<!-- /.row -->
<div class="row mar-t25">
<div class="col-xs-12 col-sm-3">
<div id="exp_card_1">
<div id="toggle-button"></div>
</div>
</div>
<div class="col-xs-12 col-sm-3">
<div class="stock-card curves2">
</div>
</div>
<div class="col-xs-12 col-sm-3">
<div id="exp_card_3" class="stock-card curves2">
</div>
</div>
<div class="col-xs-12 col-sm-3">
<div id="exp_card_4" class="stock-card curves2">
</div>
</div>
</div>
<!-- /.row -->
</div>

Is this what you're looking for?
I suggest taking a look at MDN to get deeper insights about CSS props: https://developer.mozilla.org/en-US/docs/Web/CSS/width
$(document).ready(function() {
$('#toggle-button').click(function() {
var toggleWidth = $("#exp_card_1").width() > 0 ? "0%" : "100%";
$('#exp_card_1').animate({
width: toggleWidth
});
});
});
#exp_card_1 {
position: relative;
height: 310px;
background: #2d3644;
z-index: 1;
}
#toggle-button {

In Bootstrap open Enlarge image in modal

How do I open / enlarge an image in a modal using jquery / js and not data attributes?
Anytime a user inserts an image into a content editor I need it to be clickable to expand in a modal with js, so I cannot rely on the user to input data attributes they don't know how to use.
I tried:-
<a href="/myImage.png" id="pop">
<img src="/myImage.png" style="width: 400px; height: 264px;">
Click to Enlarge
</a>
jQuery :-
$("#pop").on("click", function() {
$(this).modal();
});
Do I need to add info to the jquery to pass the image source to appear in the modal?
Thank you!!!

You can try this code if you are using bootstrap 3:
HTML
<a href="#" id="pop">
<img id="imageresource" src="http://patyshibuya.com.br/wp-content/uploads/2014/04/04.jpg" style="width: 400px; height: 264px;">
Click to Enlarge
</a>
<!-- Creates the bootstrap modal where the image will appear -->
<div class="modal fade" id="imagemodal" 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"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<h4 class="modal-title" id="myModalLabel">Image preview</h4>
</div>
<div class="modal-body">
<img src="" id="imagepreview" style="width: 400px; height: 264px;" >
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
JavaScript:
$("#pop").on("click", function() {
$('#imagepreview').attr('src', $('#imageresource').attr('src')); // here asign the image to the modal when the user click the enlarge link
$('#imagemodal').modal('show'); // imagemodal is the id attribute assigned to the bootstrap modal, then i use the show function
});
This is the working fiddle.

I have change it little bit but still can not do few things.
I added that clicking on it close it - it was easy but very functional.
<div class="modal-dialog" data-dismiss="modal">
I also need different description under each photo. I added description in footer just to show what I need.
It need to change with every photo.
HTML
<div class="modal fade" id="imagemodal" tabindex="-1" role="dialog" aria-labelledby="myModalLabel" aria-hidden="true">
<div class="modal-dialog" data-dismiss="modal">
<div class="modal-content" >
<div class="modal-body">
<button type="button" class="close" data-dismiss="modal"><span aria-hidden="true">×</span><span class="sr-only">Close</span></button>
<img src="" class="imagepreview" style="width: 100%;" >
</div>
<div class="modal-footer">
<div class="col-xs-12">
<p class="text-left">1. line of description<br>2. line of description <br>3. line of description</p>
</div>
</div>
</div>
</div>
JavaScript:
$(function() {
$('.pop').on('click', function() {
$('.imagepreview').attr('src', $(this).find('img').attr('src'));
$('#imagemodal').modal('show');
});
});
Also it would be nice if this window will open only on 100% of screen.
Here picture inside with description have more than 100% and in become scrollable...
and if screen in much bigger than pictures it shoud stop only on orginal size. for ex. 900 px and no bigger in height.

This plugin works great for me.
Bootstrap 3 lightbox plugin

I know your question is tagged as bootstrap-modal (although you didn't mention Bootstrap explicity either), but I love to see the simple way W3.CSS solved this and I think it is good to share it.
<img src="/myImage.png" style="width:30%;cursor:zoom-in"
onclick="document.getElementById('modal01').style.display='block'">
<div id="modal01" class="w3-modal" onclick="this.style.display='none'">
<div class="w3-modal-content w3-animate-zoom">
<img src="/myImage.png" style="width:100%">
</div>
</div>
Here is a link to the W3Schools modal image example to see the headers to make W3.CSS work.

So I have put together a very rough modal in jsfiddle for you to take hints from.
JSFiddle
$("#pop").on("click", function(e) {
// e.preventDefault() this is stopping the redirect to the image its self
e.preventDefault();
// #the-modal is the img tag that I use as the modal.
$('#the-modal').modal('toggle');
});
The part that you are missing is the hidden modal that you want to display when the link is clicked. In the example I used a second image as the modal and added the Bootstap classes.

<div class="row" style="display:inline-block">
<div class="col-lg-12">

Here is a solution I'm using for Bootstrap 5.
<!-- a link that triggers modal -->
More details
<div class="modal fade" id="myModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog modal-lg modal-dialog-scrollable">
<div class="modal-content">
<div class="modal-header">
<h5 class="modal-title" id="exampleModalLabel">Image Title</h5>
<button type="button" class="btn-close" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="modal-body">
<!-- include image here-->
<img src="images/img_example_8.png" alt="Image Title" class="img-fluid">
</div>
<div class="modal-footer">
<button type="button" class="btn btn-secondary" data-bs-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
The top-voted solution did not work for me as it uses Bootstrap 3 and my app does not. Basically I just followed the bootstrap 5 modal documentation. I made the modal size large so the image is larger.

css:
img.modal-img {
cursor: pointer;
transition: 0.3s;
}
img.modal-img:hover {
opacity: 0.7;
}
.img-modal {
display: none;
position: fixed;
z-index: 99999;
padding-top: 100px;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgba(0,0,0,0.9);
}
.img-modal img {
margin: auto;
display: block;
width: 80%;
max-width: 700%;
}
.img-modal div {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}
.img-modal img, .img-modal div {
animation: zoom 0.6s;
}
.img-modal span {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
cursor: pointer;
}
#media only screen and (max-width: 700px) {
.img-modal img {
width: 100%;
}
}
#keyframes zoom {
0% {
transform: scale(0);
}
100% {
transform: scale(1);
}
}
Javascript:
$('img.modal-img').each(function() {
var modal = $('<div class="img-modal"><span>×</span><img /><div></div></div>');
modal.find('img').attr('src', $(this).attr('src'));
if($(this).attr('alt'))
modal.find('div').text($(this).attr('alt'));
$(this).after(modal);
modal = $(this).next();
$(this).click(function(event) {
modal.show(300);
modal.find('span').show(0.3);
});
modal.find('span').click(function(event) {
modal.hide(300);
});
});
$(document).keyup(function(event) {
if(event.which==27)
$('.img-modal>span').click();
});
img.modal-img {
cursor: pointer;
transition: 0.3s;
}
img.modal-img:hover {
opacity: 0.7;
}
.img-modal {
display: none;
position: fixed;
z-index: 99999;
padding-top: 100px;
left: 0;
top: 0;
width: 100%;
height: 100%;
overflow: auto;
background-color: rgba(0,0,0,0.9);
}
.img-modal img {
margin: auto;
display: block;
width: 80%;
max-width: 700%;
}
.img-modal div {
margin: auto;
display: block;
width: 80%;
max-width: 700px;
text-align: center;
color: #ccc;
padding: 10px 0;
height: 150px;
}
.img-modal img, .img-modal div {
animation: zoom 0.6s;
}
.img-modal span {
position: absolute;
top: 15px;
right: 35px;
color: #f1f1f1;
font-size: 40px;
font-weight: bold;
transition: 0.3s;
cursor: pointer;
}
#media only screen and (max-width: 700px) {
.img-modal img {
width: 100%;
}
}
#keyframes zoom {
0% {
transform: scale(0);
}
100% {
transform: scale(1);
}
}
Javascript:
$('img.modal-img').each(function() {
var modal = $('<div class="img-modal"><span>×</span><img /><div></div></div>');
modal.find('img').attr('src', $(this).attr('src'));
if($(this).attr('alt'))
modal.find('div').text($(this).attr('alt'));
$(this).after(modal);
modal = $(this).next();
$(this).click(function(event) {
modal.show(300);
modal.find('span').show(0.3);
});
modal.find('span').click(function(event) {
modal.hide(300);
});
});
$(document).keyup(function(event) {
if(event.which==27)
$('.img-modal>span').click();
});
HTML:

If you have an editor, this mean the images are dynamically added by Javascript, so when using jQuery you need to select the image tag starting from an object that is already in page.
My answer will work for both cases: images displayed when page load and images dynamically added after by Javascript.
I am using a class that can be added and will open the image in modal.
The image:
<img src='/assets/image.png' style='width:100px;' class='imageViewBig'/>
The modal:
<div class="modal fade" id="modalImgageView" tabindex="-1" aria-hidden="true">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-body text-center">
<button type="button" class="btn-close bg-dark" data-bs-dismiss="modal" aria-label="Close" style="position:absolute; top:5px;right:5px;"></button>
<img src="assets/images/nophoto.png" alt="Image Title" class="img-fluid" id="modalImgageViewIMG">
</div>
</div>
</div></div>
the modal header and footer are removed
the "close" button is moved over the image in right corner
image from modal have id "modalImgageViewIMG" and is needed to change the "src" attribute
The jQuery:
$(document).on("click", ".imageViewBig", function() {
let url = $(this).attr('src');
$('#modalImgageViewIMG').attr('src', url);
$('#modalImgageView').modal('toggle');
});
click event is set on $(document)
class "imageViewBig" have a listener for "click" event and will take the "src" from the clicked image and putted to image from modal

The two above it is not run.
The table edit button:
<a data-toggle="modal" type="edit" id="{{$b->id}}" data-id="{{$b->id}}" data-target="#form_edit_masterbank" data-bank_nama="{{ $b->bank_nama }}" data-bank_accnama="{{ $b->bank_accnama }}" data-bank_accnum="{{ $b->bank_accnum }}" data-active="{{ $b->active }}" data-logobank="{{asset('components/images/user/masterbank/')}}/{{$b->images}}" href="#" class="edit edit-masterbank" ><i class="fa fa-edit" ></i></a>
and then in JavaScript:
$('.imagepreview555').attr('src', logobank);
and then in HTML:
<img src="" class="imagepreview555" style="width: 100%;" />
Not it runs.

Close loading overlay with javascript

Following is the Twitter Bootstrap snippet which I am trying to close from javascript after 5 second but I was unable to do that. Kindly let me know how can I close it.
Currently its closing when a user clicks on this button:
<button type="button" class="close" style="float: none;" data-dismiss="modal" aria-hidden="true">×</button>
http://bootsnipp.com/snippets/featured/centered-processing-modal
<!-- Static Modal -->
<div class="modal modal-static fade" id="processing-modal" role="dialog" aria-hidden="true">
<div class="modal-dialog">
<div class="modal-content">
<div class="modal-body">
<div class="text-center">
<img src="http://www.travislayne.com/images/loading.gif" class="icon" />
<h4>Processing... <button type="button" class="close" style="float: none;" data-dismiss="modal" aria-hidden="true">×</button></h4>
</div>
</div>
</div>
</div>
</div>
.modal-static {
position: fixed;
top: 50% !important;
left: 50% !important;
margin-top: -100px;
margin-left: -100px;
overflow: visible !important;
}
.modal-static,
.modal-static .modal-dialog,
.modal-static .modal-content {
width: 200px;
height: 200px;
}
.modal-static .modal-dialog,
.modal-static .modal-content {
padding: 0 !important;
margin: 0 !important;
}
.modal-static .modal-content .icon {
}

Without wanting to read the docs for you, here's the quick and dirty solution for the one in the link.
setTimeout(
function(){
$('#processing-modal button.close').click();
},
5000
);
If you want more granular control, you'll have to read the docs. This is intended to finish when some data process that it's bound to somehow is finished. That's probably somehow tied to a custom attribute and triggering an event or something.
