You can get the list of elements with class "listName", and change the first element of that list.
Javascript
window.onload = function(){
// Get elements with class name
var elements_array = document.getElementsByClassName("listName");
// Change first element
elements_array[0].style.display = "block";
}
window.onload = function(){
// Get elements with class name
var elements_array = document.getElementsByClassName("listName");
// Change first element
elements_array[0].style.display = "block";
}
.listName {
display: none;
}
<html>
<body>
<div class="listHolder">
<ul class="list">
<li>
<span class="listName">Macbook</span>
</li>
<li>
<span class="listName">Amazon Firestick</span>
</li>
<li>
<span class="listName">Keyboard</span>
</li>
<li>
<span class="listName">Headphones</span>
</li>
<li>
<span class="listName">Airpods</span>
</li>
</ul>
</div>
</body>
</html>

I think you can do with JavaScript
<script type="text/javascript">
// create the function with JavaScript
function removerClass() {
// get all elements with listName class
let element = document.getElementsByClassName("listName");
// get the first element
element = element[0];
// remove the element's class
element.classList.remove("listName");
}
// call the function when the page is loaded
removerClass()
</script>
I hope it's usefull

User input validation Bootstrap 4 and JQuery?

I started learning Bootstrap 4 validation and there are few things that are not clear to me. Some of the situations are confusing in case where input fields that are not required are showing valid-feedback / invalid-feedback. Also, I'm wondering if there is a way to trigger validation with button on click instead of submit process? Here is example of what I have so far:
// Example starter JavaScript for disabling form submissions if there are invalid fields
(function() {
'use strict';
window.addEventListener('load', function() {
// Fetch all the forms we want to apply custom Bootstrap validation styles to
var forms = document.getElementsByClassName('needs-validation');
// Loop over them and prevent submission
var validation = Array.prototype.filter.call(forms, function(form) {
form.addEventListener('submit', function(event) {
if (form.checkValidity() === false) {
event.preventDefault();
event.stopPropagation();
}
form.classList.add('was-validated');
}, false);
});
}, false);
})();

In the example above I used the code for validation form the Bootstrap web site. There is very little explained on how this works. I have few questions:
How I can trigger validation on click since I will use ajax to send request to the server?
Why fields that are not required are turning green (color around the input)?
How I can use pattern attribute to validate input value if it's correct or not with custom message for the user?
Please let me know if anyone knows how to achieve this?
Thank you.

Change localstorage on form submit from 0 to 1

and my current JS code
localStorage.setItem('competitionformlockdown', '0' || '1');
if(localStorage.getItem('competitionformlockdown') == '1') {
$(".competitionformlockdown input").prop('disabled', true);
$(".competitionformlockdown input[type=submit]").prop('disabled', true)
}
I want the forms to load with the value of 0 then when the form is submitted the value switches to 1 and triggers the competitionformlockdown on load and persists.
The forms are loading as 0 but the value is not switching to 1 on submit.
I'm new to localstorage so this is all new to me.
Any help is appreciated.

you can add a script tag which sets the value to zero on form load, and then after the submit you can return the script tag to set to 1.
Form load
<script>
var currentvalue = localStorage.getItem('competitionformlockdown') || '0';
localStorage.setItem('competitionformlockdown', currentValue);
</script>
On submit
localStorage.setItem('competitionformlockdown', '1');

Following changes are done.
1) Clicked item is saved in 'option' variable.
2) Show the form field based on data in 'option' variable.

It is seems confusing because you want to start with the URL box shown so you need to use a mix of ng-show and ng-hide then override them on click.

Form submits even when i use prevent default on submit button click

what i want is that when i click on button "find reservation", the form submit should not refresh the page. Instead it should enable some fields in find reservation form underneath. But I am not able to achieve that. I am using bootstrap.
Here is my html part:-
<div class="container">
<div class="jumbotron checkInGuest">
<h3 class="h3Heading">Request for following information from guest</h3>
<form class="form-horizontal" id="checkInForm">
<div class="form-group">
<label for="reservationId" class="col-md-4">Reservation Id</label>
<div class="col-md-8">
<input type="text" class="form-control" id="reservationId" name="reservationId" required>
</div>
</div>
<div class="form-group">
<label for="dlNum" class="col-md-4">Driver License #</label>
<div class="col-md-8">
<input type="number" class="form-control" id="dlNum" min="0" name="dlNum" required>
</div>
</div>
<div class="form-group">
<div class="col-md-2">
<button type="submit" class="btn btn-success" id="findResButton">Find Reservation</button>
</div>
</div>
</form>
<!-- Form when info is found. Initially all fields are disabled-->
<div class="clear clearWithBorder"></div>
<h3 class="h3Heading">Information Found</h3>
<form class="form-horizontal">
<div class="form-group">
<label for="resId" class="col-md-3">Reservation Id</label>
<div class="col-md-3">
<input type="text" class="form-control" id="resId" name="resId" disabled>
</div>
<label for="dlNumReadOnly" class="col-md-3">Driver License #</label>
<div class="col-md-3">
<input type="number" class="form-control" id="dlNumReadOnly" min="0" name="dlNumReadOnly" disabled>
</div>
</div>
<div class="form-group">
<label for="guestFullName" class="col-md-3">Guest Full Name</label>
<div class="col-md-3">
<input type="text" class="form-control" id="guestFullName" name="guestFullName" disabled>
</div>
<label for="email" class="col-md-3">Email</label>
<div class="col-md-3">
<input type="email" class="form-control" id="email" name="email" disabled>
</div>
</div>
<div class="form-group">
<label for="numRooms" class="col-md-3">Rooms Booked</label>
<div class="col-md-3">
<input type="number" class="form-control readable" id="numRooms" name="numRooms" disabled>
</div>
<label for="roomType" class="col-md-1">Room Type</label>
<div class=" col-md-2">
<label for="smoking">
<input type="radio" name="roomType" id="smoking" class="roomType readable" disabled> Smoking
</label>
</div>
<div class=" col-md-3">
<label for="nonSmoking">
<input type="radio" name="roomType" id="nonSmoking" class="roomType readable" disabled>Non-Smoking
</label>
</div>
</div>
<div class="form-group">
<label for="discount" class="col-md-3">Discount</label>
<div class="col-md-3">
<select class="form-control readable" id="discount" disabled>
<option selected>0%</option>
<option>10%</option>
<option>20%</option>
<option>30%</option>
</select>
</div>
<label for="checkInDate" class="col-md-3">CheckIn Date</label>
<div class="col-md-3">
<input type="date" class="form-control readable" id="checkInDate" name="checkInDate" disabled>
</div>
</div>
<div class="form-group">
<label for="checkOutDate" class="col-md-3">CheckOut Date</label>
<div class="col-md-9">
<input type="date" class="form-control readable" id="checkOutDate" name="checkInDate" disabled>
</div>
</div>
<div class="form-group">
<div class="col-md-2">
<button type="button" class="btn btn-success" id="roomOrdButton">Confirm Room Order</button>
</div>
</div>
</form>
<div class="clear clearWithBorder"></div>
<h3 class="h3Heading">Final Room Order</h3>
<form class="form-horizontal">
<div class="form-group">
<label for="perInEachRoom" class="col-md-12">Number of people in each room</label>
<div class="col-md-8 " id="perInEachRoom">
</div>
<div class="form-group">
<div class="col-md-2">
<button type="button" class="btn btn-success" id="checkInButton">Check In</button>
</div>
</div>
</div>
</form>
</div>
</div>
And this is jquery part:-
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.3/jquery.min.js"></script>
<script src="js/jquery.validate.min.js"></script>
<script src="js/bootstrap.min.js"></script>
<script>
$("#checkInForm").validator();
$("#findResButton").click(function(e){
e.preventDefault();
$(".readable").prop("disabled",false);
});
$("#roomOrdButton").click(function(){
var numberOfRooms=$("#numRooms").val();
var counter=0;
var container=$('<div/>');
$(".readable").prop("disabled",true);
for(counter=1;counter<=numberOfRooms;counter++){
container.append('<label for="room">Room '+counter+'</label><input type="number" class="form-control readable" name="checkInDate" />');
}
$("#perInEachRoom").html(container);
});
$("#checkInButton").click(function(){
$("#perInEachRoom").html("");
});
</script>

You need to put your code in a document.ready() function, so:
$(document).ready(function() {
$("#checkInForm").validator();
$("#findResButton").click(function(e){
e.preventDefault();
$(".readable").prop("disabled",false);
});
$("#roomOrdButton").click(function(){
var numberOfRooms=$("#numRooms").val();
var counter=0;
var container=$('<div/>');
$(".readable").prop("disabled",true);
for(counter=1;counter<=numberOfRooms;counter++){
container.append('<label for="room">Room '+counter+'</label><input type="number" class="form-control readable" name="checkInDate" />');
}
$("#perInEachRoom").html(container);
});
$("#checkInButton").click(function(){
$("#perInEachRoom").html("");
});
});
You should also have a look at this question: Form is submitted when I click on the button in form. How to avoid this?
Long story short, you should use
<button type="button"...
not
<button type="submit"...

Actually, all I did is:-
$("#checkInForm").submit(function(e)
{
e.preventDefault();
});
And that solved it. I didnt have to change button type or anything. Basically, in future when I will make AJAX calls I will have the code underneath preventDefault statement.
