I know i need to use
$('#myModal').modal('show');
$('#myModal').modal('hide');
i just dont know where to put it

First remove the data-toggle="modal" target="#myModal" from #btnValidate
<button type="button" class="btn btn-primary" id="btnValidate">Next</button>
Then change your if statment inside your validate function to:
if (re) {
className = 'msg pass';
textMessage = 'Bitcoin address is valid';
$('#myModal').modal('show')
}
Note that you import jquery twice, which can lead to bugs. Remove one import and make sure jquery is imported before bootsrap.js

need help understanding why searchQuery.value is undefined

so i'm currently trying to build search icon on the header clickable where you're able to search for, in this case, pokemon names, however i keep getting a console error
searchQuery.value undefined
Not sure why because the code looks valid.
Also, when you click on the search icon the icon goes above it and once you hit submit on the input it duplicates. I'm sure it's all connected the bug.
No sure why this is happening and would greatly appreciate any advice to fix this.

Since searchQuery is a jQuery object, you need to use its .val() method to set and get the value. So change.
searchQuery.value =
searchQuery.value.charAt(0).toUpperCase() +
searchQuery.value.slice(1);
to
searchQuery.val((i, value) => value[0].toUpperCase() + value.slice(1));

How do I get the bootstrap modal to work in my code?

Hey there I am just have trouble bringing up a modal working with bootstrap. Theoretically I have a list of pokemon that I fetched from another website. Then each pokemon is supposed to act as a button to where i can then click on and receive more information about. I would appreciate some help as I am pretty lost.
Thanks

1 - There is few errors in your code. To open a bootstrap modal there is a method:
$('#myModal').modal('show');
2 - Then you cleaned the structure of the modal with the innerHTML instead of the modal-body and you are trying to recreate all the elements dynamically.
What you can do is just replacing the content of the modal body or do not forget to re-create every element of the modal which is not what you did.
Here is a working example:
https://codepen.io/alxtaz/pen/WNXYOrd

JavaScript + Bootstrap Dropdown list not allowing me to select the item

I have this bootstrap layout, which is a container inside an accordion-item. There is a dropdown button, containing messages and there's another button that opens a modal to insert a new message and display it in the dropdown list, using localStorage.
When the page loads or is refreshed, I can select the dropdown item normally, but when I add the item, it actually shows up in the list, but I can't select it nor any other item and the selected item is kept there, until the page is reloaded again.
I can still add more messages using the modal and they will still show up in the list.
There's no error in the console to guide me.
The JavaScript code is located at the bottom of the code.

Had to change in order to solve my issue (which I still don't know):
function getMensagem() {
let valueMensagem = document.getElementById('mensagem').value;
if (valueMensagem != 0) {
$('select option:selected').each(function (e) {
$('#ContentPlaceHolder1_ddMensagensCopy').val(valueMensagem);
});
}
else {
$('#ContentPlaceHolder1_ddMensagensCopy').val('');
}
}
function updateSelectMensagem() {
const select = document.querySelector('#mensagem');
const oldMessage = JSON.parse(localStorage.getItem('mensagem')) || false;
if (oldMessage) {
select.innerHTML = "<option value='0'> Selecione uma mensagem </option>";
oldMessage.forEach(element => {
select.innerHTML += `<option class='dropdown-item'>${element}</option>`
});
} else {
localStorage.setItem('mensagem', '[]')
}
}
function addItemMensagem() {
const text = document.getElementById('txtMensagem').value;
const database = JSON.parse(localStorage.getItem('mensagem')) || [];
if (database && text.length > 3) {
const repetido = database.find(item => item === text.value);
if (!repetido) {
const novasMensagens = [...database, text];
localStorage.setItem('mensagem', JSON.stringify(novasMensagens))
updateSelectMensagem();
text.value = ''
}
}
}
updateSelectMensagem()
<div class="col-4">
<div class="dropdown-boleto">
<select id="mensagem" class="btn btn-secondary select">
<option value="0">Selecione uma mensagem</option>
</select>
</div>
</div>
.select option {
background: white;
color: #212529;
}

In fact, everything works as expected

Call JavaScript Function Contained on _Layout.cshtml

Please help, new web developer alert!
MVC + JavaScript :)
I have a .cshtml page that has a submit button. When I press that button I want to call a JavaScript function contained on my _Layout.cshtml page.
Unfortunately I get a function not found error.
'ReferenceError: validateCheckBoxesInForm is not defined'
Here is the cshtml page...
#model FrontEnd.Web.Areas.PresentationToPolicy.ViewModels.CaseSummary.InsurersReferralViewModel
#{
ViewBag.Title = "Refer To Insurers";
}
<div>
<form asp-area="PresentationToPolicy" asp-controller="CaseSummary" asp-action="ReferToInsurers" method="POST" id="documentDownload">
<div class="panel panel-danger">
<div class="panel-body" style="padding-bottom: 15px">
<div class="row">
<div class="col-md-12">
<input class="btn btn-success btn-lg" type="submit" value="Finish" onclick="validateCheckBoxesInForm(event, 'documentDownload', 'Whooops!', 'You Must Select At Least One Insurer For Referal')" style="max-width: 100%; width: 100%"/>
</div>
</div>
</div>
</div>
</form>
</div>
Here a cut down version of my _Layout.cshtml (the script is loaded just after bootstrap etc, at the start of the body)
#inject Microsoft.ApplicationInsights.AspNetCore.JavaScriptSnippet JavaScriptSnippet
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8" />
</head>
<body style="background-color: #f6f8fa">
<environment include="Development">

<script src="~/lib/jquery-ui/jquery-ui.js"></script>
<script src="~/lib/bootstrap/dist/js/bootstrap.js"></script>
<script src="~/js/dist/manifest.js"></script>
<script src="~/js/dist/vendor.js"></script>
<script src="~/js/dist/scripts.js" asp-append-version="true"></script>
</environment>
<div class="container body-content">
#RenderBody()

<footer>
<p style="vertical-align: baseline">© 2017 - ABACUS Portfolio Portal</p>
</footer>
</div>
#RenderSection("Scripts", required: false)
</body>
</html>
Oh and the script that contains the function!
function validateCheckBoxesInForm(event, formId, title, message) {
let validated = false;
let form = $(`#${formId}`);
let elements = form.elements;
event.preventDefault();
for (var i = 0; i < elements.length; i++) {
if (elements[i].type === 'checkbox') {
if (elements[i].checked) {
validated = true;
form.submit();
break;
}
}
}
if (validated === false) {
$('<div></div>')
.appendTo('body')
.html(
`<div id="validateModal" class="modal fade">
<div class="modal-dialog">
<div class="modal-content" style="border-color: #f00">
<div class="modal-header">

<h3 class="modal-title">

</div>
<div class="modal-body">
<h4>${message}</h4>
</div>
<div class="modal-footer">
<button type="button" class="btn btn-danger" data-dismiss="modal" style="width: 150px">Ok</button>
</div>
</div>
</div>
</div>`
);
$('#validateModal').modal('show');
}
}
And finally a cut down version of 'View Source'
<body style="background-color: #f6f8fa">

<div class="container body-content">
<form method="POST" id="documentDownload" action="/PresentationToPolicy/CaseSummary/ReferToInsurers/43cffe87-2d8f-43eb-8ad2-e0b046fc8d20">
<div class="panel panel-danger">
<div class="panel-body" style="padding-bottom: 15px">
<div class="row">

</div>
</div>
</div>
</div>
</form>
</body>
</html>
If I press view source and click on the script link I get this...
webpackJsonp([19],{
/***/ 749:
/***/ (function(module, exports, __webpack_require__) {
module.exports = __webpack_require__(750);
/***/ }),
/***/ 750:
/***/ (function(module, exports, __webpack_require__) {
"use strict";
//Global Functions that will be run of every page
//Called via _Layout.cshtml
function validateCheckBoxesInForm(event, formId, title, message) {
var validated = false;
var form = $('#' + formId);
var elements = form.elements;
event.preventDefault();
for (var i = 0; i < elements.length; i++) {
if (elements[i].type === 'checkbox') {
if (elements[i].checked) {
validated = true;
form.submit();
break;
}
}
}
if (validated === false) {
$('<div></div>').appendTo('body').html('<div id="validateModal" class="modal fade">\n <div class="modal-dialog">\n <div class="modal-content" style="border-color: #f00">\n <div class="modal-header">\n <button type="button" class="close" data-dismiss="modal" aria-label="Close"><span aria-hidden="true">×</span></button>\n <h3 class="modal-title">\n ' + title + '\n </h3>\n </div>\n <div class="modal-body">\n <h4>' + message + '</h4>\n </div>\n <div class="modal-footer">\n <button type="button" class="btn btn-danger" data-dismiss="modal" style="width: 150px">Ok</button>\n </div>\n </div>\n </div>\n </div>');
$('#validateModal').modal('show');
}
}....
So I guess my question is how to I call the function contained on the _Layout page from the child cshtml page?
I guess I could use a script section on the page, but this function is shared by multiple places. So I kinda need a central location to keep the code dry.

Prevent from clicking, change class name, hide the highlight - jQuery

I have a three issue in this app.
First issue is that the show button doesn't change its name to "show offer" when the app is closed after we open it.
Second, the app doesn't prevent a user from clicking second and third button. He can click only one offer, but now the user can click on every.
Third, the user can highlight a new offer by clicking once, then he can hide the highlight, but cannot highlight it again and never. Appreciate any help.
//// hide offer before the Dom is loaded
//$('ul').hide()
$(document).ready(function() {
function showHideOffer() {
$('ul').slideToggle();
}
//click to show offers
$('.card').on('click', '.showOffers', showHideOffer, function() {
$('.showOffers').html('Hide Offers');
});
//click to hide offers - change name to show offers doesn't work!!
$('.card').on('click','.showOffers', showHideOfferfunction() {
$('.showOffers').html('Show Offers');
});
// click to book, to show info and close button and span
$('li').on('click', 'button', function(){
var offerName = $(this).closest('.tour').data('name');
var offerPrice = $(this).closest('.tour').data('price')
var message = $('<ol class="breadcrumb"><li class="breadcrumb-item active" style="color:#3CB371">Success! You have booked '+offerName+' offer for '+offerPrice+'!</li></ol>');
$(this).closest('.tour').append(message);
$(this).prev().closest('.details').remove();
$(this).remove();
});
// filter new offers by clicking a "new" button
$('#buttons').on('click','.filterNew', function() {
$('.tour').filter('.newOffer').addClass('highlightnew');
$('.highlightpopular').removeClass('highlightpopular');
//click second time and the highlight is hidden
$('#buttons').on('click', '.filterNew', function() {
$('.highlightnew').removeClass('highlightnew');
});
});
// filter by popular offers
$('#buttons').on('click', '.filterPopular', function() {
$('.tour').filter('.popular').addClass('highlightpopular');
$('.highlightnew').removeClass('highlightnew');
});
});

First Issue Solve : Checkout Here :
Change the code to
$('.card').on('click', '.showOffers', showHideOffer, function() {
//$('.showOffers').html('');
$(this).text( $(this).text() == 'Hide Offers' ? "Show Offers" : "Hide Offers");
});
Instead Of :
$('.card').on('click', '.showOffers', showHideOffer, function() {
$('.showOffers').html('Hide Offers');
});
//click to show offers
$('.card').on('click', '.showOffers', showHideOffer, function() {
//$('.showOffers').html('');
$(this).text( $(this).text() == 'Hide Offers' ? "Show Offers" : "Hide Offers");
});
//click to hide offers - change name to show offers doesn't work!!

To Resolve your first issue modify your function like below
var ValuesShowOrHidden = 0;
$('.card').on('click', '.showOffers', showHideOffer, function () {
if (ValuesShowOrHidden == 0) {
$('.showOffers').html('Hide Offers');
ValuesShowOrHidden = 1;
}
else if (ValuesShowOrHidden==1) {
$('.showOffers').html('Show Offers');
ValuesShowOrHidden = 0;
}
});
For the Second Issue try the below modification in your function
$('li').on('click', 'button', function () {
var offerName = $(this).closest('.tour').data('name');
var offerPrice = $(this).closest('.tour').data('price')
var message = $('<ol class="breadcrumb"><li class="breadcrumb-item active" style="color:#3CB371">Success! You have booked ' + offerName + ' offer for ' + offerPrice + '!</li></ol>');
$(this).closest('.tour').append(message);
$(this).prev().closest('.details').remove();
$(this).remove();
$('li').unbind("click");
});
