How to Multiple checkbox post unchecked post 0 value

I have multiple of checkbox within a form that are saved in a loop after submission. The problem is when there are unchecked checkbox then I can't get the post value. I know if I want to get 0 value so create hidden input with same name and set value to 0, but this is multiple checkbox.
Here is my code:
<div class="col-4">
<label class="switch switch-lg">
<input type="checkbox" name="order[1]" id="order-1">
<input type="hidden" id="hd-check-1" name="order[1]" value="0">
</div>
<div class="col-4">
<label class="switch switch-lg">
<input type="checkbox" name="order[2]" id="order-2">
<input type="hidden" id="hd-check-2" name="order[2]" value="0">
</div>
<div class="col-4">
<label class="switch switch-lg">
<input type="checkbox" name="order[3]" id="order-3">
<input type="hidden" id="hd-check-3" name="order[3]" value="0">
</div>
$(document).ready(function() {
var count = 3;
for (i = 1, j = 1; i <= count, j <= count; i++, j++) {
var check = $('#order-' + i + '');
var hidden = $('#hd-check-' + j + '');
check.on('click', function() {
if ($(this).prop("checked") == true) {
$(this).val(1);
hidden.attr('disabled', 'disabled');
console.log('ck: ', ck);
}
else if ($(this).prop("checked") == false) {
hidden.removeAttr('disabled');
$(this).val(0);
}
})
}
})
Above code if I checked the checkbox not effected the hidden input. Any idea how to solve this? That I want is when the checkbox not checked and I submit the form I want to get the value.
Thanks for advance.

Javascript: How to check if each input value is duplicated to another input value

So i have a dynamic input field came from append with different class name and names, i want to check each of input field value already exist or duplicate.
This would look like
The first criteria_name is default and the others are appendend.
<input type="text" name="criteria_name" class="criteria_name">
<input type="text" name="criteria_name2" class="criteria_name2">
<input type="text" name="criteria_name3" class="criteria_name3">
<input type="text" name="criteria_name4" class="criteria_name4">
<input type="text" name="criteria_name5" class="criteria_name5">
I am trying to check each one of those if there is no duplicated else proceed.
var critname_arr = [];
var input_check;
var crit_name_of_first = $('input.criteriaNames').val();
var acappended = append_crit_header+1;
var count_to = 0;
for(var ab = 2; ab<=acappended; ab++){
var crit_arr;
if(crit_name_of_first == $('input.criteria_each_name'+ab+'').val()){
alert("Criteria cannot be duplicate");
return false;
}else{
input_check = $('input.criteria_each_name'+ab);
input_check.each(function(){
crit_arr = $.trim($(this).val());
});
critname_arr.push(crit_arr);
}
if($('input.criteria_each_name'+ab+'').val() == critname_arr[count_to]){
alert('criteria cannot be duplicate');
return false;
}
count_to++;
}
console.log(critname_arr);

Here is just an example of how you can do it. In the fiddle change one of the values to one that is already in another field (make a duplicate value) to see it do something. If there are no duplicates, it will not do anything. Click the "Button" text to run the duplicate check:
jsFiddle: https://jsfiddle.net/o52gjj0u/
<script>
$(document).ready(function(){
$('.ter').click(function(e) {
var stored = [];
var inputs = $('.criteria_name');
$.each(inputs,function(k,v){
var getVal = $(v).val();
if(stored.indexOf(getVal) != -1)
$(v).fadeOut();
else
stored.push($(v).val());
});
});
});
</script>
<!-- Just use an array name for the input name and same class name as well -->
<div class="ter">Button</div>
<input type="text" name="criteria_name[]" class="criteria_name" value="1" />
<input type="text" name="criteria_name[]" class="criteria_name" value="2" />
<input type="text" name="criteria_name[]" class="criteria_name" value="3" />
<input type="text" name="criteria_name[]" class="criteria_name" value="4" />
<input type="text" name="criteria_name[]" class="criteria_name" value="5" />

Check at most four check box and store checked value to textbox

I am displaying some check boxes. The user can check a maximum of 4 boxes. I store the checked value in 4 textboxes.
My problem: How can I correctly store the "new" checked value when the user randomly unchecks one box and checks another?
I store values as follows: First checked into item_1, second checked into item_2, third checked into item_3 ... If the user unchecks the first checked box, for example, how can I store the value of the next box he or she checks into item_1? Please help.
Simplified code
<input type="checkbox" name="prodname_1" id="prodname_1"value="1"/>
<input type="checkbox" name="prodname_2" id="prodname_2"value="2"/>
<input type="checkbox" name="prodname_3" id="prodname_3"value="3"/>
.
.
<input type="checkbox" name="prodname_10" id="prodname_10"value="10"/>
<input type="text" name="item_0" id="item_0"value=""/>
<input type="text" name="item_1" id="item_1"value=""/>
<input type="text" name="item_2" id="item_2"value=""/>
<input type="text" name="item_3" id="item_3"value=""/>
$(document).ready(function (e)
{
counter=0;
$('input[id^="prodname_"]').change(function()
{
id = $(this).attr('id');
var arr = id.split('_');
valueChecked=$('#'+id).val();
if(this.checked)
{
if(counter==4)
{
alert('Allready checked 4 items');
this.checked=false;
return false;
}
$("#item_"+counter).val(valueChecked);
++counter;
}
});
});

Instead of retaining a counter, just count the number of checked boxes when the change occurs.
Revised to use the logic you intended (took a little while to figure that out) :)
JSFiddle: http://jsfiddle.net/TrueBlueAussie/tmLnbvv0/9/
$(document).ready(function (e) {
var $items = $('input[id^="item_"]');
var checkboxes = $('input[id ^= "prodname_"]').change(function () {
var id = $(this).attr('id');
var arr = id.split('_');
valueChecked = $(this).val();
// Count of checked checkboxes
var counter = checkboxes.filter(':checked').length;
if ($(this).is(':checked')) {
// count the checked checkboxes
if (counter > 4) {
alert('Already checked 4 items');
$(this).prop('checked', false);
} else {
// Add to the first available slot
$items.filter(function(){return $(this).val() == ""}).first().val(valueChecked);
}
} else {
// Remove the matching value
$items.filter(function(){return $(this).val() == valueChecked;}).first().val('');
}
});
});
note: The "jQuery way" for changing checkboxes is to use prop('checked', booleanvalue) (also changed above)
V2 - If you don't want gaps:
This version is actually simpler as it just clears the items and fills them, in order, with any checked checkbox values.
JSFiddle: http://jsfiddle.net/TrueBlueAussie/tmLnbvv0/13/
$(document).ready(function (e) {
var $items = $('input[id^="item_"]');
var $checkboxes = $('input[id ^= "prodname_"]').change(function () {
// Count of checked checkboxes
var counter = $checkboxes.filter(':checked').length;
// count the checked checkboxes
if (counter > 4) {
alert('Already checked 4 items');
$(this).prop('checked', false);
}
// Clear all the items
$items.val('');
// Fill the items with the selected values
var item = 0;
$checkboxes.filter(':checked').each(function () {
$('#item_' + (item++)).val($(this).val());
});
});
});

Look at
$(document).ready(function(e) {
var counter = 0,
$items = $('input[name^="item_"]');
$('input[id^="prodname_"]').change(function() {
var id = this;
if (this.checked) {
if (counter == 4) {
this.checked = false;
return;
}
$("#item_" + counter).val(this.value).attr('data-value', this.value);
++counter;
} else {
var $item = $items.filter('[data-value="' + this.value + '"]');
var index = $items.index($item);
$items.slice(index, counter).each(function(i) {
var $n = $items.eq(index + i + 1);
$(this).val($n.val() || '').attr('data-value', $n.attr('data-value'));
});
counter--;
$("#item_" + counter).val('').removeAttr('data-value');
}
});
});

Manipulating label with checkboxes

Scenario:
Three unchecked check-boxes, each with different id and value.
An empty paragraph (or label) with id = par.
[CB1] has value 1.
[CB2] has value 2.
[CB3] has value 3.
Now, when I click cb1 -> 'par' gets and prints the value of cb1.
Clicking on cb3, 'par' gets the value of cb1+cb3.
Clicking cb1, 'par' subtracts the value of cb1 and so on.. I think you get the point.
How can I achieve this with only HTML and JavaScript (without jQuery).
<input type="checkbox" id="1" value="1" />
<input type="checkbox" id="2" value="2" />
<input type="checkbox" id="3" value="3" />
<p id="par"></p>

This will do it: jsfiddle example (updated to remove alert)
HTML:
<input type="checkbox" id="1" value="1" onclick='checkClicked(event)'/>
<input type="checkbox" id="2" value="2" onclick='checkClicked(event)'/>
<input type="checkbox" id="3" value="3" onclick='checkClicked(event)'/>
<p id="par"></p>
JavaScript:
function checkClicked(element)
{
var targetElement = element.target;
var newVal = targetElement.value;
if( !targetElement.checked )
{
newVal *= -1;
}
var currentVal = document.getElementById('par').innerHTML;
if( currentVal )
{
newVal = parseInt(currentVal) + parseInt(newVal);
}
document.getElementById('par').innerHTML = newVal;
}

<label>
<input type="checkbox" id="check1" value="check1" onchange="alterP(this);"/>check1
</label>
<label>
<input type="checkbox" id="check2" value="check2" onchange="alterP(this);"/>check2
</label>
<label>
<input type="checkbox" id="check3" value="check3" onchange="alterP(this);"/>check3
</label>
<p id="par"></p>
js Code
function alterP(obj) {
var par = document.getElementById('par');
var txt = (obj.checked) ? obj.value : "";
par.innerHTML = txt;
}

<script>
document.getElementById("1").addEventListener("click", processCheck);
document.getElementById("2").addEventListener("click", processCheck);
document.getElementById("3").addEventListener("click", processCheck);
function processCheck() {
var theParagraph = document.getElementById("par");
var currentValue = 0;
if (!isNaN(parseInt(theParagraph.textContent))) {
currentValue = parseInt(theParagraph.textContent)
}
if (this.checked) {
theParagraph.textContent = currentValue + parseInt(this.value);
}
else {
theParagraph.textContent = currentValue - parseInt(this.value);
}
}
</script>

Add the sum of from the value select of radiobutton

For instance, radiobutton one = value 1, radiobutton two = value 2.
Here is the code I have:
Script file:
<script type="text/javascript">
$(document).ready(function () {
$("div[data-role='footer']").prepend('Back');
$(".Next").click(function () {
$.mobile.changePage("#" + $("#Answer").val());
});
$("input[type=radio]").click(function () {
var answer = $(this).val();
$("#Answer").val(answer);
});
$('.Answer').live("click", function () {
var NextQuestionID = $(this).attr('NextQuestionId');
if (NextQuestionID == '') {
location.href = "/Surveys/Index";
}
$("#survey").load('/Questions/GetQuestion', { Id: NextQuestionID }, function () {
$('#answerInput').textinput();
$(".Answer").button();
});
});
});
and here is my markup:
<input type="radio" name="Answer" id="radio-choice-1" value="Question2" />
<input id="Answer" class="Answer" type="hidden" value="first" />
<div class="innerspacer">
Next
</div>
How do I assign the radio button as value from 1 to 4 and sum up the value for all the question?

There is a lot going on in your question and it is unclear what you want. I'm taking a guess and assuming you have a say 5 radio buttons and you want the 5th radio button value to be the sum of the other 4 values. Is that correct?
Here is an example of doing that: jsfiddle
HTML:
<div id="container">
<label>
<input type="radio" name="something" value="1">
A?
</label>
<label>
<input type="radio" name="something" value="3">
B?
</label>
<label>
<input type="radio" name="something" value="5">
C?
</label>
<label>
<input type="radio" name="something" value="">
All?
</label>
</div>
JavaScript:
$(document).ready(function() {
var choices = $('input[name="something"]');
var total = 0;
choices.each(function() {
var choice = $(this);
var value = parseInt(choice.val(), 10);
if (!isNaN(value)) {
total += value;
}
});
choices.filter(':last').val(total);
});
You will need to adapt this to your HTML.
