Bootstrap modal not showing with JavaScript " $("#attributeUpdateModal").modal('show');"

I am new to JavaScript and I'm working on a project with openlayers and geoserver and I need to add features to a layer. I succeeded to draw a feature but for saving it I need to enter its attributes which I implemented in a bootstrap modal but when I finish drawing the modal doesn't show I get just a transparent page and it stays like that.
Here it is my html code :
<!-- Attribute Update Modal -->
<div class="modal " id="attributeUpdateModal" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">
<div class="modal-dialog modal-dialog-centered modal-dialog-scrollable">
<div class="modal-content">
<div class="modal-header">
<h3 class="modal-title" id="exampleModalLabel">Attributes</h3>
<button class="btn-close btn-light" data-bs-dismiss="modal" aria-label="Close"></button>
</div>
<div class="attribute-body">
<div id="attributeContainer"></div>
</div>
<div class="modal-footer">
<div class="col-md-12 text-center">
<button id="btnSave" type="button" class="btn btn-success">
Save
</button>
<button id="btnCancel" type="button" class="btn btn-warning">
Cancel
</button>
</div>
</div>
</div>
</div>
</div>
Here it is my JavaScript code :
drawInteraction.on("drawend", function (e) {
var feature = e.feature;
feature.set("geometry", feature.getGeometry());
modifiedFeatureList.push(feature);
var featureProperties = editGeoJSON
.getSource()
.getFeatures()[0]
.getProperties();
document.getElementById("attributeContainer").innerHTML = "";
for (var key in featureProperties) {
if (featureProperties.hasOwnProperty(key)) {
if (key != "geometry") {
if (key != "id") {
var div = document.createElement("div");
div.className = "mb-3";
var lbl = document.createElement("label");
lbl.className = "form-label";
lbl.innerHTML = key;
var inputBox = document.createElement("input");
inputBox.className = "form-control";
inputBox.id = key;
inputBox.value = "";
div.appendChild(lbl);
div.appendChild(inputBox);
document.getElementById("attributeContainer").appendChild(div);
}
}
}
}
$("#attributeUpdateModal").modal('show');
});
Does anyone have an idea about this issue?

change src iframe on javascript not working

i try to chenge the src ifame in js but i cant success.
the i frame always empty and without content of new window src.
if i put the src inside the iframe its work ( i cant do that becuse i need id to src and i got that on js function)
html:
<div class="modal fade" id="myModal" role="dialog">
<div class="modal-dialog modal-lg">
<div class="modal-content">
<div class="modal-header">
<button type="button" class="close" data-dismiss="modal">×</button>
</div>
<div class="modal-body">
<iframe src="" id="iframePOP" style="zoom:0.60" width="99.6%" height="250" frameborder="0"></iframe>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default text-center" data-dismiss="modal">close</button>
</div>
</div>
</div>
js:
function ShowPopup(id) {
$('#myModal').on('show', function () {
document.getElementById("iframePOP").src="/Game.aspx?GameId=" + id;
});
$('#myModal').modal({ show: true })
}
i tried also this:
function ShowPopup(id) {
var frameSrc = "/Game.aspx?GameId=" + id;
$('#myModal').on('show', function () {
$('iframe').attr("src", frameSrc);
});
$('#myModal').modal({ show: true })
}

Have you tried assigning your whole domain name into your var frameSrc?
EDIT:
Try changing $('#myModal').on('show', function () { ... } into $('#myModal').is(':visible', function(){ ... }); and make sure the ID of the modal you are referencing is correct. If that didn't work, try this $('#myModal').on('show.bs.modal', function (e) { ... })

Is there anyway to open/show a div after the page has reloaded?

I want to open a modal window after a page is reloaded.I am planning to open that modal inside a div.So is there any way to open a div after the page has been loaded?

if you wont to do it with only javascript , you can by using url hash parameters .
The idea is when page first load js will add a word to URL ,So when the page reload again js will see the word in url so we will know that the page is reloaded and how many time.
like:
var url = window.location.href;
var hash = url.split('#')[1];
var recount;
if(hash != null){
recount = parseInt(hash.split('-')[1])+1;
hash = hash.split('-')[0];
}
if (hash == "re") {
var elm = document.getElementById("first");
elm.innerHTML = "the page has been reloaded ("+recount+")";
window.location.href = url.split('#')[0] + "#re-"+recount;
//alert("the page has been reloaded ("+recount+")");
} else {
window.location.href += "#re-0";
}
<body>
<button onclick="location.reload()">Reload</button>
<div id ="first">first page</div>
</body>
After add bootstrap and jquery
var url = window.location.href;
var hash = url.split('#')[1];
var recount;
if(hash != null){
recount = parseInt(hash.split('-')[1])+1;
hash = hash.split('-')[0];
}
if (hash == "re") {
$("#first").hide();
$("#modal_text").html("the page has been reloaded ("+recount+")");
$("#myModal").modal();
window.location.href = url.split('#')[0] + "#re-"+recount;
} else {
window.location.href += "#re-0";
}

</head>
<body>
<button onclick="location.reload()">Reload</button>
<div id ="first"><h1>first page</h1></div>
<!-- Modal -->
<div class="modal fade" id="myModal" 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>
<h4 class="modal-title">Modal Header</h4>
</div>
<div class="modal-body">
<p id='modal_text'></p>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-default" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</body>
but I suggest using cookies or localStorage for best way .

How to close & open a modal like Bootstrap

I want to create a modal like Bootstrap ...
I have wrote this codes :
<button type="button" data-target="#myModal" class="btn btn-primary">Open Modal</button>
<div class="modal fadeIn" id="myModal">
<div class="modal-header">
Roj Framework <span class="close-btn">×</span>
</div>
<div class="modal-content">
Hi, This Roj Framework !
</div>
<div class="modal-footer">
Continue ...
</div>
</div>
But I have a problem in understanding how to close & open it. I put a data-target for button to match with Modal Box ID & I don't display the modal from the beginning ..., So I wrote this code but It doesn't work ...
$('.modal').css('display', 'none');
$('button').click(function(){
var boxID = $(this).data('target');
var modalBox = $('.modal');
var modalBoxAttr = modalBox.attr('id');
if('boxID' == 'modalBoxAttr') {
modalBox.css('display', 'block');
}
});

There a few mistakes with your code.
Mistake 1:
Here:
if('boxID' == 'modalBoxAttr')
You are currently checking the strings and not the objects. What you have written is the following:
If the string "boxId" is equal to the string "modalBoxAttr" do something. And both strings are not the same, so you get a false result.
Mistake 2:
You are complicating the code too much.
You can just simplify it like this.
$('button').click(function(){
var boxID = $(this).data('target');
var boxObject = $(boxID);
if(boxObject.length) {
boxObject.toggle();
}
});
.modal { display: none; }
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<button type="button" data-target="#myModal" class="btn btn-primary">Open Modal</button>
<div class="modal fadeIn" id="myModal">
<div class="modal-header">
Roj Framework <span class="close-btn">×</span>
</div>
<div class="modal-content">
Hi, This Roj Framework !
</div>
<div class="modal-footer">
Continue ...
</div>
</div>
Use more often console.log() to debug your code and check if you are actually entering a specific section and if your logic is correct.

Try following approach.
Remove data-target="#myModal" from button
<button type="button" class="btn btn-primary">Open Modal</button>
Button click:
$('button').click(function(){
$("#myModal").modal('show');
}});

Modal only displays first image

I have got an issue where my modal only displays the first image. What I am trying to do is that i want to display a dynamic gallery. Every "post" can have 0-* images and based on how many images there are in the database for this post thats how many will appear. I came across this issue and have found others having similar issues but not exactly the same.
This code is basically a partial view where the post is generated. The Modal is displayd correct amount of times but only displays the first picture.
Thanks so much in advance
<ul class="imageRow">
#foreach (var item in Model)
{
<div class="col-lg-3 col-md-4 col-xs-6">

You are using the same ID (id="image-gallery") for all of your modals. HTML element IDs are supposed to be unique! You need to generate different IDs for each of your modals.
