I want to show a modal using jQuery, but all window becomes blured like this:
This is the js:
$(document).ready(function () {
$('#addLocation').click(function () {
$('#locationModal').modal('show');
})
$('#addDepartment').click(function () {
$('#departmentModal').modal('show');
})
$('#addRole').click(function () {
$('#roleModal').modal('show');
})
});
And html page:

How to fix this ? What can be the cause of the problem ? Is a better way to make bootstrap-modal ?
Just add data-backdrop="false" to your modal. so... the code will look like this:
<div id="locationModal" class="modal fade" tabindex="-1" role="dialog" data-backdrop="false">
that's it! your modal will show on top. Hopefully will help.
These are the default Bootstrap z-index settings:
#zindex-navbar: 1000;
#zindex-dropdown: 1000;
#zindex-popover: 1060;
#zindex-tooltip: 1070;
#zindex-navbar-fixed: 1030;
#zindex-modal-background: 1040;
#zindex-modal: 1050;
.modal should have the z-index value of 1050, if these default settings haven't been changed. Theoretically, if you delete that line with z-index: 1; it should use the default value defined by Bootstrap before your user css

I am trying to determine if an element is visible in the viewport when the user scrolls. This code works outside of a Modal, but not inside the Modal. I imagine it has something to do with the
z-index, but no matter what I try it does not work. Any ideas?

Check a feature called Intersection observer. It lets you listen for an element when it comes into view and then fire a callback.

My bootstrap modal doesnt show, im getting just faded screen. Its is working on mobile and tablet, but doesnt work on desktop? Anyone have idea why is this happening?
here is code:

<div class="modal fade bd-example-modal-lg" tabindex="-1" role="dialog" aria-labelledby="myLargeModalLabel" aria-hidden="true">

padding: 0!important;
overflow: visible;
display: block;
}
.modal:before {
content: '';
display: inline-block;

position: absolute;

height:100%;
}
js:
$('#myModal').on('shown.bs.modal', function (e) {
$('#myInput').trigger('focus')
})
Any advice would be helpful, thanks! :)
There are so many conflicts with css and js and classes in html.
Here is the suggestion: if you want any custom change in the modal add a class in the main div and then make the changes with that class only.

You forgot the -bs- inside the classes:
<button
type="button"
class="btn btn-primary"
data-bs-toggle="modal"
data-bs-target="#myModal"
>
Open Modal
</button>
<div
id="myModal"
class="modal fade bd-example-modal-lg"
tabindex="-1"
role="dialog"
aria-labelledby="myLargeModalLabel"
aria-hidden="true"
>
<div class="modal-dialog modal-lg">

<div class="modal-header">
<button type="button" class="close" data-bs-dismiss="modal">

type="button"
class="btn btn-default"
data-bs-dismiss="modal"
>
Close
</button>

If I am correct you want the focus to be on an input element when the modal opens:

I have a little problem, I'm trying to fit my image in my modal's div.
This is what I have now and I want it to be like i draw in red
What i have, in red is what I really want
The original image is this, so you have an ideia real size
Real image
My code right now is something like this .
modal
<div class="modal-header">
<button type="button" class="close" onclick="hideModal()">×</button>
</div>
<!-- Modal Body -->
<div class="modal-body">
<img class="modal-img" src="/images" >
</div>
**img **
<img style='height: 100%; width: 100%; object-fit: contain' onclick="showModal(this)" src="{$product.image}" alt="" class="img-responsive">
Give position relative to the parent div of the image and it will fit the modal. Some working example in this link
<div class="image-container">
<img class="modal-img" src="https://i.stack.imgur.com/bgvRi.png" >
</div>
.image-container {
position: relative;
}
.image-container img {
width: 100%;
height: auto; // or 100%
}
Edit as per comments:
(I guess that you don't want to use the image as a background). You can style some bootstrap3 components:
.modal-dialog {
margin: 0;
height: 100vh;
width: 100%;
overflow: auto; /*in case content overlap*/
}
.modal-body img {
height: calc(100vh - 160px); /* in order that both header and footer of .modal would be on the screen */
width: auto;
margin: auto;
display: block;
}

OLD Answer:
This happen since you are using object-fit AND declaring width and height to be 100%.
Maybe something like this:
img{
width:100%;
height:400px;
object-fit: contain;
}

I have a bootstrap modal on load page it works properly but I want to add class to an element if it active and remove it if it not active I tried the following but it doesn't work properly!
here is the example
$(window).load(function() {
$("#myModal").modal("show");
});
if ($("#myModal").hasClass("in")) {
$(".test").addClass("active");
} else {
$(".test").removeClass("active");
}
.test {
width: 100px;
height: 100px;
background-color:#e0e0e0;
}
.active {

Use shown.bs.modal and hidden.bs.modal to detect modal is open or not then add or remove class.
$(window).load(function() {
$("#myModal").modal("show");
});
$('#myModal').on('shown.bs.modal', function() {
$(".test").addClass("active");
console.log('Active');
}).on('hidden.bs.modal', function() {
$(".test").removeClass("active");
console.log('Not Active');
});
.test {
width: 100px;
height: 100px;
background-color: #e0e0e0;
}
.active {
background-color: #000;

I've got a long full screen popup modal(parent-modal). Inside this modal(parent-modal) there is another popup modal(child-modal).
If I scroll the "parent-modal" and then open "child-modal", the "child-modal" modal is not vertically centered.
hope this might be useful to you!
.modal {
}
.vertical-alignment-helper {
display:table;
height: 100%;
width: 100%;
}
.vertical-align-center {
/* To center vertically */
display: table-cell;
vertical-align: middle;
}
.modal-content {
/* Bootstrap sets the size of the modal in the modal-dialog class, we need to inherit it */
width:inherit;
height:inherit;
/* To center horizontally */
margin: 0 auto;
}
