jquery.repeater with bootstrap custom-switch failure

Good Evening,
I have a problem with the jquery form repeater plugin and bootstrap.
I have this form element witch is part of the repeater form:
<div class="custom-control custom-switch">
<input type="checkbox" class="custom-control-input" id="questionSwitch" name="question_correct[]">
<label class="custom-control-label" for="questionSwitch">Richtige Antwort</label>
</div>
Now is the problem if the repeater repeat this element and I click on the second or third repeated item on the switch the switch on the first item get changed not the one I clicked. Because they all three have the same id.
Does anyone have an idea how to fix this? Its the first time working with the form repeater.
Here is a bit more of the Code
$(function () {
'use strict';
if (!$('#multiple-choice').attr('checked')) {
$('#questions').hide();
}
$('#multiple-choice').on('click', function () {
if (this.checked)
$('#questions').show();
else $('#questions').hide();
});
// form repeater jquery
$('#whitelist-new-question').repeater({
show: function () {
$(this).slideDown();
// Feather Icons
if (feather) {
feather.replace({ width: 14, height: 14 });
}
},
hide: function (deleteElement) {
if (confirm('Möchten Sie diese Antwort wirklich löschen?')) {
$(this).slideUp(deleteElement);
}
}
});
});

Ok i got a fix for that.
in the js script i created a variable number and added this code in the show event of the repeater:
show: function () {
var inputSwitch = $(this).find('.custom-control-input');
var labelSwitch = $(this).find('.custom-control-label');
var id = 'currect-switch-' + number;
inputSwitch.attr("id", id);
labelSwitch.attr("for", id);
$(this).slideDown();
// Feather Icons
if (feather) {
feather.replace({ width: 14, height: 14 });
}
number++;
},

Javascript not working as intended

My javascript code doesnt seem to run when i use this codes to validate the radio button is clicked. Its suppose to dropdown the inputs when the card radio button is clicked and it is suppose to slide up the inputs when the paypal button is clicked.1st code javascript. 2nd code html.
if (document.getElementById('paypal').checked) {
//Paypal radio button is checked
$(".input-fields").slideDown("slow");
} else if (document.getElementById('card').checked) {
//Card radio button is checked
$(".input-fields").slideUp("slow");
};
<div class="panel-body">
<h2 class="title">Checkout</h2>
<div class="bar">
<div class="step active"></div>
<div class="step active"></div>
<div class="step"></div>
<div class="step"></div>
</div>
<div class="payment-method">
<label for="card" class="method card">
<div class="card-logos">
<img src="img/visa_logo.png" />
<img src="img/mastercard_logo.png" />
</div>
<div class="radio-input">
<input id="card" type="radio" name="payment"> Pay $<%= total %> with credit card
</div>
</label>
<label for="paypal" class="method paypal">
<img src="img/paypal_logo.png" />
<div class="radio-input">
<input id="paypal" type="radio" name="payment"> Pay $<%= total %> with PayPal
</div>
</label>
</div>
<div class="input-fields">
<div class="column-1">
<label for="cardholder">Cardholder's Name</label>
<input type="text" id="cardholder" />
<div class="small-inputs">
<div>
<label for="date">Valid thru</label>
<input type="text" id="date" placeholder="MM / YY" />
</div>
<div>
<label for="verification">CVV / CVC *</label>
<input type="password" id="verification" />
</div>
</div>
</div>
<div class="column-2">
<label for="cardnumber">Card Number</label>
<input type="password" id="cardnumber" />
<span class="info">* CVV or CVC is the card security code, unique three digits number on the back of your card separate from its number.</span>
</div>
</div>
</div>

All you missed was to add the logic inside a function and add it to an event using addEventListener() for value change.
We use document.getElementById() to get both the input elements by ID and then add the event listener to fire on change of value.
document.getElementById("card").addEventListener("change", validate);
document.getElementById("paypal").addEventListener("change", validate);
function validate() {
if (document.getElementById('paypal').checked) {
//Paypal radio button is checked
$(".input-fields").slideDown("slow");
} else if (document.getElementById('card').checked) {
//Card radio button is checked
$(".input-fields").slideUp("slow");
};
}
document.getElementById("card").addEventListener("change", validate);
document.getElementById("paypal").addEventListener("change", validate);

Event Listeners

You need to add your javascript inside an event listener. For Example
$("input[name='payment']").click(function ()
{
if (document.getElementById('paypal').checked)
{
//Paypal radio button is checked
$(".input-fields").slideDown("slow");
}
else if (document.getElementById('card').checked)
{
//Card radio button is checked
$(".input-fields").slideUp("slow");
}
;
});

Custom social media site posting process not posting to user's profile

I'm working on a social media site for a client that was built by another company. Currently I'm working on the posting system where users can post. The original code had it where users had to go through 3 steps first then hit the button to post. The client wanted to remove the steps and just have it setup similar to facebook. I moved the code around and removed the steps but the "Post" button doesn't work now. When I click on it, it just says "Posting" and doesn't do anything else.
If you go to seegossip.com and sign up as a user and login, click on the orange smileys icon in the top right, it will bring up the posting popup.
Below is the original posting process code:
<div class="popup close">

This is a little advanced for me and I've been stuck on this site for a couple weeks trying to figure out what the problem is so please help.

can't get jquery parentsUntil to work

I've been trying to use the jquery parentsUntil method to hide a button until a radio box is selected, but I can't seem to get it to work. It's probably something obvious, but it's been bugging me for a couple of days now. Can anyone see what I'm doing wrong.
(function($) {
$(function(){
$('.last-item').change(function() {
if( $(this).val() != '' ) {
$(this).parentsUntil('.step').find('.button-next').removeClass('hide');
$(this).parentsUntil('.step').find('.button-next').addClass('show');
console.log("changing the last item");
}
});
});
})(jQuery);
.hide {

JS Fiddle

.parentsUntil() gets "the ancestors of each element in the current set of matched elements, up to but not including the element matched by the selector,".
Try .closest() instead

This is likely what you meant?
No need to hide if value is empty since you cannot deselect a radio.
If you want to hide when some value is empty, use .toggle($(this).val()!="")
(function($) {
$(function() {
$('.last-item').on("click",function() { // click assumes radio as last item
$(this).closest("div.step").find('.button-next').show();
});
});

.button-next { display:none }

Try this snippet. I hope it will work
Note:remove hide class from -> class="button-next hide"
$(function(){
$('.button-next').hide();
$('input[type="radio"]').click(function() {
if($(this).prop('checked') == true) {
$('.button-next').show();
}
else {
$('.button-next').hide();
}
});
});

All good sensible answers, guys, but none of them worked for me. In the end I had to use
$(this).closest('.step-3').find('.button-next').css('display','block');

JAVA Script function:
This is the function on which i want to know which tab is active that is defined in above jsp
<script type="text/javascript">
function im()
{
/*alert("calling im function");
var tabname = document.getElementById("tab1");
if(tabname){
alert("tab1 is active");
}else{
alert("tab 1 is not active");
}*/
if($('#img1').val()=="" || $('#img2').val()=="" || $('#img3').val()=="" || $('#img4').val()=="" || $('#img5').val()=="" || $('#img6').val()=="")
{
alert("Please select image");
$('#submit').prop('disabled',true);
}
else
{
$('#submit').prop('disabled',false);
}
}

Try like
$('.tab').click(function(){
var a=$(this).attr('id');
$('#sample').html('Active Tab is'+a);
});
Fiddle

you can assign same class to all tab and bind the click function in document ready, you will get the current object by 'this'.
$('.tab').click(function(){
$(this).val();
});

$('.tab').click(function(){
var x=$(this).prop('id');
$('#lbl').html('Active Tab'+ x);
});

I'm new here but you could add a worthless class to the active tab on click, then on the button click retrieve the id or whatever you want.
jQuery
//edit: added function to add and remove class, replaced text to illustrate
$(function () {
$('.tab_content').click(function () {
$('.tab_content').removeClass('active').text('');
$(this).addClass('active').text('am active');
})
$('#button').click(function () {
$('.tab_content').each(function () {
if ($(this).hasClass('active')) {
alert($(this).attr('id')+" is the active tab");
alert($(this).text()+" is the text");
}
});
});
});
html
<div id='1' class='tab_content'>not</div>
<div id='2' class='tab_content active'>am active</div>
<div id='3' class='tab_content'>not</div>
<div id='4' class='tab_content'>not</div>
<button id='button' style='width:50px; height:50px;'>Click</button>
