Problem with XML HttpRequest and bootstrap modal

I'm filling bootstrap cards with an external json file via XML HttpRequest. This works, all information is shown in the cards.
Now I would like to press "More info" to open a bootstrap modal with more information about the item.
The problem is when I press "More info" the data of the first item1 is always taken.
I know that the solution is that I have to pass the id of the elements to the modal, so that the correct data of the elements can be retrieved.
But I don't understand how I can pass the id of an item to the modal?
JSON File
[{
"id": 1,
"name": "item1",
"price": "€5",
"size": "XS",
"color": "Green"
}, {
"id": 2,
"name": "item2",
"price": "€10",
"size": "S",
"color": "Yellow"
}, {
"id": 3,
"name": "item3",
"price": "€15",
"size": "M",
"color": "Blue"
}, {
"id": 4,
"name": "item4",
"price": "€20",
"size": "L",
"color": "Red"
}, {
"id": 5,
"name": "item5",
"price": "€25",
"size": "XL",
"color": "Gray"
}, {
"id": 6,
"name": "item6",
"price": "€30",
"size": "XXL",
"color": "Black"
}]
JS script of my program
<script>
const divRes = document.querySelector('#divResult');
myRequest = () => {
let xhr = new XMLHttpRequest();
xhr.open('GET', 'files/elements.json', true);
xhr.send();
xhr.onload = function() {
if (xhr.readyState === xhr.DONE) {
if (xhr.status != 200) {
divRes.innerHTML = `Error ${xhr.status}: ${xhr.statusText}`;
} else {
const arrResponse = JSON.parse(xhr.responseText);
divRes.innerHTML = createHTMLCard(arrResponse);
}
}
};
xhr.onerror = function() {
divRes.innerHTML = "Request failed";
};
}
createHTMLCard = (arrObj) => {
let res = '';
for (let i = 0; i < arrObj.length; i++) {
res +=

return res;

Bootstrap cards
Bootstrap modal

the problem is that the button refers to a html id. In this case every Button has the target exampleModal
<button [..] data-bs-target="#exampleModal">More info</button>
So you need to create for every button a diffrent target and add something like #exampleModal-"+${arrObj[i].id}+"
Same you need to do on the modal class where the button refers.
<div class="modal fade" id="exampleModal-"+${arrObj[i].id}+" tabindex="-1" aria-labelledby="exampleModalLabel" aria-hidden="true">`

Thank You

Your show modal code should work as shown below, just need to include the bootstrap libraries as shown below
$(function(){
$('show').on('click', function(){
$('#myChartmodal').modal('show');
});
});

How to clear an input field in Javascript / Jquery

I am using Typeahead Jquery plugin. Each time I click on the button a Bootstrap modal will be shown and I can select multiple options inside my input.
my problem is :
When I close the modal and reopen it the previous selected values are still shown inside the input. I need to empty cache each time and reload my page so that next time the input will be empty.
I used different ideas when the modal is closed it will reset the input to empty but still not working.
here my ideas :
$('.typeahead').typeahead().bind('typeahead:closed', function () {
$(this).val("");
});
or
$("#myinput").val('');
Any suggestions please ? Here is my code. Thank you for your help.
$(document).ready(function() {
var dataDefaultColumns = [{
"name": "country",
"id": "country",
"type": "Shipment"

Bootstrap Modal and Badges

I have the following lines of code in my webpage - example/demo.
HTML:
<p data-toggle="modal" data-target="#messagesModal">Messages <span class="badge">2</span>
</p>
<!-- Modal -->
<div class="modal fade" id="messagesModal" 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">Messages</h4>
</div>
<div class="modal-body">
<div class="alert fade in">
×
<strong>Message 01</strong>:
<p>Lipsum Ipsum
</p>
</div>
<div class="alert fade in">
×
<strong>Message 02</strong>:
<p>Ipsum Lipsum</p>
</div>
</div>
<div class="modal-footer">
<div class="col-md-8 pull-left">
</div>
<div class="col-md-4">
<button type="button" class="btn btn-default pull-right" data-dismiss="modal">Close</button>
</div>
</div>
</div>
</div>
</div>
How can I update the badge to represent the correct amount of messages in the modal?
For example, when the user closes or removes a message in the modal, the badge will go from displaying the number 2 to 1?
Also, is it possible to display the text "There are no more messages." when all of the messages have been removed?

Try this:
//Find message number initially, before editing
$(".badge").text($(".alert").length);
//when the modal is closed
$('#messagesModal').on('hidden.bs.modal', function () {
//Set .badge text equal to the length of the .alert array, i.e the number of messages
$(".badge").text($(".alert").length);
//If there are no '.alert' divs, i.e. no messages
if ($(".alert").length == 0) {
$(".badge").text("No messages");
}
});
This takes all the .alert elements (messages) into an array, and sees how long that array is (i.e. how many messages there are).
Then, it updates .badge to reflect that number.
Working JSFiddle: http://jsfiddle.net/joe_young/62hbqmtp/

Well... I've spend some time, but all that you should do for now:
populate message array with your actual data;
add some actual AJAX for removing messages.
So...
$(function() {
var informer = $("#messageInformer a");
var refreshBadge = function(messageCount) {
var badge = informer.find(".badge");
if (messageCount > 0) {
if (!badge.length) {
informer.text("Messages ");
informer.append("<span class=\"badge\">" + messageCount + "</span>");
} else {
badge.text(messageCount);
}
} else {
informer.text("No messages");
}
};
var buildMessage = function(message) {
var htmlMessage = "<div class=\"alert fade in\">";
htmlMessage += "×";
htmlMessage += "<strong>" + message.title + "</strong>:";
htmlMessage += "<p>" + message.text + "</p>";
return htmlMessage;
}
// There should be real data
var messages = [
{ id: "1", title: "Message 01", text: "Lipsum Ipsum" },
{ id: "2", title: "Message 02", text: "Ipsum Lipsum" }];
refreshBadge(messages.length);
informer.on("click", function(e) {
e.preventDefault();
var modalBody = $(".modal-body");
modalBody.empty();
for (var i = 0; i < messages.length; i++) {
modalBody.append(buildMessage(messages[i]));
}
});
$("body").delegate(".alert .close", "click", function() {
var messageId = $(this).data("id");
// There should be some AJAX possibly
messages = messages.filter(function(el) {
return el.id != messageId;
});
if (messages.length == 0) {
$("#messagesModal").modal("hide");
}
refreshBadge(messages.length);
});
});

How to load image into Bootstrap Modal from JSON Flickr API

Below is the code I am working with as an example.
When I click each image from the Flickr feed I want to be able to load the Bootstrap Modal (which it does) but display that particular photo in the Modal (which it currently doesnt).
I've tried numerous different things. But I am unable to get it to work.
Example at http://jahax.com/ins/
<div class="container">
<h2 style="text-align: center;">Demonstration</h2>
<p class="text-center">Demo of Bootstrap, jQuery & JSON API</p>
<div class="row text-center">

Change your 2nd script to this:
<script type="text/javascript">
// Send Content to Bootstrap Modal
$(document).on('click', 'img', function(){
var sr=$(this).attr('src');
$('#mimg').attr('src',sr);
$('#myModal').modal('show');
});
</script>
