how to store values of list items in array on check box click and remove on unclick

I am working on a quote page where the user can click on features which will be in the form text field and the user can also request a quote
here is what I did so far
<div class="buy-features-box">
<div class="box-head">
<div class="box-head-content">
<div class="package-name">
<h2>Sample features for Seller/ Vendor</h2>
</div>
<div class="select-all-btn">
<input class="btn-check check1 form-check-input" name="product" value="100" type="checkbox" onclick="totalIt()">

</div>
<div class="collapse-opener collapsed" data-toggle="collapse" data-target="#features3" aria-expanded="true" aria-controls="features3">

here is my jquery code:
<script type="text/javascript">
$(".form-check-input").change(function() {
var abc = []; //move the array to here
$('li input[type="checkbox"]:checked').each(function() {
var $row = $(this).closest('li');
$('h3', $row).each(function(i) {
abc.push($(this).text());
})
document.getElementById("features").value = abc.join(',');
});
});
$('input:checkbox').change(function() {
var total = 0;
$('input:checkbox:checked').each(function() { // iterate through each checked element.
total += isNaN(parseInt($(this).val())) ? 0 : parseInt($(this).val());
});
$("#total").val("$" + total.toFixed(2));
});
</script>
now here I am getting values and showing them correctly in the input box of the form but if the user unchecks certain features they are not getting removed from the input field
basically I am storing values in the array "abc" on checkbox checked property but not able to remove on uncheck them.

If you move document.getElementById("features").value = abc.join(','); out of your li .each() function, then everything seems to work just fine.
Problem is that you are only updating the value of the input if there is a checked input.
Demo
$(".form-check-input").change(function() {
var abc = []; //move the array to here
$('li input[type="checkbox"]:checked').each(function() {
var $row = $(this).closest('li');
$('h3', $row).each(function(i) {
abc.push($(this).text());
})
});
document.getElementById("features").value = abc.join(',');
});

hi I don't remove parnet.
My code:
<div class="prdctfltr_add_scroll">
<div class="prdctfltr_checkboxes">
<label class="prdctfltr_ft_">
<input type="checkbox" value="">
<span>
<img src="" onerror="delNoneOptionFilters(this)" class="product_filter_none_option">
<script>function delNoneOptionFilters( x ){ $(x).closest('label').remove; }</script>
</span>
</label>
<label class="prdctfltr_ft_popularity">
<input type="checkbox" value="popularity">

<input type="checkbox" value="price-desc">
<span>Price: high to low</span>
</label>
</div>
</div>
I want delete label class="prdctfltr_ft_"

remove is not a property It is a function you have to use like this $(x).closest('label').remove().
function delNoneOptionFilters( x ){
$(x).closest('label').remove();
}
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<div class="prdctfltr_add_scroll">
<div class="prdctfltr_checkboxes">
<label class="prdctfltr_ft_">
<input type="checkbox" value="">
<span>
<button onclick="delNoneOptionFilters(this)">delete</button>
</span>
</label>
<label class="prdctfltr_ft_popularity"><input type="checkbox" value="popularity"><span>Popularity</span></label><label class="prdctfltr_ft_rating"><input type="checkbox" value="rating"><span>Average rating</span></label><label class="prdctfltr_ft_date"><input type="checkbox" value="date"><span>Newness</span></label><label class="prdctfltr_ft_price"><input type="checkbox" value="price"><span>Price: low to high</span></label><label class="prdctfltr_ft_price-desc"><input type="checkbox" value="price-desc"><span>Price: high to low</span></label>
</div>
</div>

Please Try This:-
function delNoneOptionFilters( x ){ $(x).parents('label').remove(); }

Select all in checkbox at the same time with multiple select all

Can I ask how to code a "select all" in a checkbox at the same time with multiple select all?
$(document).ready(function() {
$('.allcheckboxes').click(function() {
$(this).next().parent().parent().parent().toggleClass('checkallbox');
if($('#selectall_wrapper').hasClass('checkallbox')) {
$('#selectall_wrapper input[type="checkbox"]').prop('checked', true);
} else {
$('#selectall_wrapper input[type="checkbox"]').prop('checked', false);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="selectall_wrapper">
<li>
<div class="form-group">
<input id="checkedall" class="allcheckboxes" type="checkbox">
<label for="checkedall">Select all services</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox1" type="checkbox">
<label for="checkbox1">Service 1</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox2" type="checkbox">
<label for="checkbox2">Service 2</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox3" type="checkbox">
<label for="checkbox3">Service 3</label>
</div>
</li>
</ul>
<ul id="selectall_wrapper">
<li>
<div class="form-group">
<input id="checkedall" class="allcheckboxes" type="checkbox">
<label for="checkedall">Select all products</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox1" type="checkbox">
<label for="checkbox1">product 1</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox2" type="checkbox">
<label for="checkbox2">product 2</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox3" type="checkbox">
<label for="checkbox3">product 3</label>
</div>
</li>
</ul>

Using your code, you can use another wrapper and add that to your function. (this could be cleaned up and greatly simplified, but you get the idea.)
$(document).ready(function() {
$('.allcheckboxes').click(function() {
$(this).next().parent().parent().parent().toggleClass('checkallbox');
if($('#selectall_wrapper').hasClass('checkallbox')) {
$('#selectall_wrapper input[type="checkbox"]').prop('checked', true);
} else{
$('#selectall_wrapper input[type="checkbox"]').prop('checked', false);
} if($('#selectall_wrapper_2').hasClass('checkallbox')) {
$('#selectall_wrapper_2 input[type="checkbox"]').prop('checked', true);
} else {
$('#selectall_wrapper_2 input[type="checkbox"]').prop('checked', false);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<ul id="selectall_wrapper">
<li>
<div class="form-group">
<input id="checkedall" class="allcheckboxes" type="checkbox">
<label for="checkedall">Select all services</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox1" type="checkbox">
<label for="checkbox1">Service 1</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox2" type="checkbox">
<label for="checkbox2">Service 2</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox3" type="checkbox">
<label for="checkbox3">Service 3</label>
</div>
</li>
</ul>
<ul id="selectall_wrapper_2">
<li>
<div class="form-group">
<input id="checkedall_2" class="allcheckboxes" type="checkbox">
<label for="checkedall_2">Select all products</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox1" type="checkbox">
<label for="checkbox1">product 1</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox2" type="checkbox">
<label for="checkbox2">product 2</label>
</div>
</li>
<li>
<div class="form-group">
<input id="checkbox3" type="checkbox">
<label for="checkbox3">product 3</label>
</div>
</li>
</ul>

uncheck selected checkbox when one of the checkbox option has been selected

I have 2 groups of checkbox options on same page. below is the code.
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="1" th:text="borrower1" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="2" th:text="borrower2" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="3" th:text="borrower3" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="4" th:text="borrower4" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerEthnicity1}" th:value="1" th:text="Ethnicity1" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerEthnicity2}" th:value="2" th:text="Ethnicity2" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerEthnicity3}" th:value="3" th:text="Ethnicity3" />
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerEthnicity4}" th:value="4" th:text="Ethnicity4" />
</label>
</div>
Now,
User can select first 3 check boxes but clicking the 4th (last) one should
select the 4th (last) one and deselect all other of the set. Same should
happen for all checkbox sets.
Example : User can select A,B,C checkbox at a same time but when he checks D
all the above selected checkboxes should get unselected. Similarly for E,F,G
and H. I hope I am clear now.
Please help me on this. I hope I am clear, if not please do let me know

The below code section should work according to your requirement
$(document).ready(function() {
$('.checkbox1').on('click', function() {
var last_chekbox1 = $('.checkbox1:last');
if (last_chekbox1.is(':checked')) {
$('.checkbox1').prop('checked', false);
$(this).prop('checked', true);
}
});
$('.checkbox2').on('click', function(e) {
var last_chekbox2 = $('.checkbox2:last');
if (last_chekbox2.is(':checked')) {
$('.checkbox2').prop('checked', false);
$(this).prop('checked', true);
}
});
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="1" th:text="borrower1" class="checkbox1" /> A
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="2" th:text="borrower2" class="checkbox1" /> B
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="3" th:text="borrower3" class="checkbox1" /> C
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerRace1}" th:value="4" th:text="borrower4" class="checkbox1" /> D
</label>
</div>
<hr>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerEthnicity1}" th:value="1" th:text="Ethnicity1" class="checkbox2" /> E
</label>
</div>
<div class="col-xs-12">
<label class="checkbox-inline">
<input type="checkbox" th:field="*{borrowerEthnicity2}" th:value="2" th:text="Ethnicity2" class="checkbox2" /> F
</label>
</div>
<div class="col-xs-12">

$('checkbox1').on('click'function(){
$('checkbox').attr('checked',false)
$(this).attr('checked',true)
})
try something like this

Checking a checkbox using jquery from another div using prop()

I don't know why this is not working. I tried the same way as seen in some of the stackflow solutions but still not getting the image as well as the checkbox response.
<form>
<div class="col s12">
<div style="display:none">
<label for="Type">Type</label>
<input type="hidden" id="Type">
<div class="checkbox">
<input type="checkbox" id="Type1" checked="false" name="Type[]" value="1">
<label for="Type1">Fruits</label>
</div>
<div class="checkbox">
<input type="checkbox" id="Type2" checked="false" name="Type[]" value="2">
<label for="Type2">Vegetables</label>
</div>
<div class="checkbox">
<input type="checkbox" id="Type3" checked="false" name="Type[]" value="3">
<label for="Type3">Pulses</label>
</div>
<div class="checkbox">
<input type="checkbox" id="Type4" checked="false" name="Type[]" value="4">
<label for="Type4">SeaFoods</label>
</div>
</div>
<p>Food types</p>
<ul>
<li class="unchkd"><span class="food-icons fruit"></span> <span class="iconname">Fruits</span></li>
<li class="unchkd"><span class="food-icons vegi"></span> <span class="iconname">Vegetables</span></li>
<li class="unchkd"><span class="food-icons pulses"></span> <span class="iconname">Pulses</span></li>
<li class="unchkd"><span class="food-icons seaFood"></span> <span class="iconname">Sea Food</span></li>
</ul>
</div>
</div>
</form
JQuery for this:
$(document).ready(function(){
$("span.food-icons.fruit").click(function(){
if($(".checkbox #Type1").prop("checked") == false){
$('.checkbox #Type1').prop('checked', true);
$("span.food-icons.fruit").css("background-image", "url(images/icons/fruits1.png)";
}
else{
$('.checkbox #Type1').prop('checked', false);
$("span.food-icons.fruit").css("background-image", "url(images/icons/fruits.png)";
}
});
});

Your clicking span.iconname not span.food-icons. wrap .iconname in .food-icons
You are also missing a closing bracket on you $.css selector.
$(document).ready(function(){
$(".food-icons.fruit>.iconname").click(function(){
console.log("click");
if($(".checkbox #Type1").prop("checked") == false){
$('.checkbox #Type1').prop('checked', true);
$("span.food-icons.fruit").css("background-image", "url(images/icons/fruits1.png)");
}
else{
$('.checkbox #Type1').prop('checked', false);
$("span.food-icons.fruit").css("background-image", "url(images/icons/fruits.png)");
}
});
