Logic on value increment in input box - javascript

I have created several input boxes with some logic behind. I need to create a logic for only one input box that if it's the first click, it should increment the value from 0 to 2, and then just a normal increment +1. so to make it clear, the addition should be as follows:
0 > 2 > 3 > 4
If the user clicks on the minus, it should reduce by 1 unless it comes to the value of 2 as than the subtraction should be to 0, so to explain its as follows:
4 > 3 > 2 > 0
$("#1, #2, #3, #4").prop('disabled', true);
$('.add').click(function () {
var value1 = $('#1').val();
var value2 = $('#2').val();
var value3 = $('#3').val();
var value4 = $('#4').val();
var totalValue = parseInt(value1) + parseInt(value2) + parseInt(value3) + parseInt(value4);
if ( totalValue >= 5){
$('.add').prop('disabled', true);
} else {
$(this).prev().val(+$(this).prev().val() + 1);
}
});
$('.sub').click(function () {
if ($(this).next().val() > 0) $(this).next().val(+$(this).next().val() - 1);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.11.1/jquery.min.js"></script>

Code to submit boolean button with keypresses

I am trying to make my code submit a boolean button with two options. I am trying to trigger the S and K keypress to submit each button. I saw the following code, but when I try it, it doesn't run.
This is my HTML code. Each button has a function that give me a timestamp of the click, submit the page and save the option that the participant chooses (A or B).
<!DOCTYPE html>
<html>
<body>
<p style="text-align: center;">
<button class="btn btn-primary btn-large"
onclick="myFunction()" name="offer_accepted1" id="of1A" value="True"> A</button>
<button class="btn btn-primary btn-large"
onclick="myFunction()" name="offer_accepted1" id="of1B" value="False">B</button>
</p>
<input type="hidden" name="timestamp1" value="0" />
{{ form.timestamp1.errors }}
<input type="text" id="c1" name="c1" value="0" />
{{ form.c1.errors }}
<!--The keypress code-->
<script>
var input = document.getElementById("of1A");
input.addEventListener("keyup", function(event) {
if (event.keyCode === 75) {
event.preventDefault();
document.getElementById("of1A").click();
});
var input = document.getElementById("of1B");
input.addEventListener("keyup", function(event) {
if (event.keyCode === 83) {
event.preventDefault();
document.getElementById("of1B").click();
}
});
//The function that gives me a timestamp
function myFunction() {
var n = Date.now();
document.getElementById("c1").value = n;
}
</script>
</body>
Without the keypress code the code runs in the next way:
function myFunction() {
var n = Date.now();
document.getElementById("c1").value = n;
}
<p style="text-align: center;">
<button class="btn btn-primary btn-large"
onclick="myFunction()" name="offer_accepted1" value="True"> A</button>
<button class="btn btn-primary btn-large"
onclick="myFunction()" name="offer_accepted1" value="False">B</button>
</p>
<input type="hidden" name="timestamp1" value="0" />
{{ form.timestamp1.errors }}
<input type="text" id="c1" name="c1" value="0" />
{{ form.c1.errors }}

Submit two button with different keycodes

I have the following code to save a person's timestamps when he clicks on one of two buttons.
On the screen they must choose which button they prefer if A or B.
function myFunction() {
var n = Date.now();
document.getElementById("c1").value = n;
}
<p style="text-align: center;">
<button class="btn btn-primary btn-large"
onclick="myFunction()" name="offer_accepted1" value="True"> A</button>
<button class="btn btn-primary btn-large"
onclick="myFunction()" name="offer_accepted1" value="False">B</button>
</p>
<input type="hidden" name="timestamp1" value="0" />
{{ form.timestamp1.errors }}
<input type="text" id="c1" name="c1" value="0" />
{{ form.c1.errors }}
I want to program two keys to submit the buttons. But I need each key to be one of the buttons to know which option they chose. Also, I don't want to lose the timestamp. Can someone help me?
You mean this?
I added ID to field
function myFunction(but) {
var n = Date.now();
document.getElementById("timestamp1").value = n;
document.getElementById("c1").value = but.value;
}
<p style="text-align: center;">
<button class="btn btn-primary btn-large"
onclick="myFunction(this)" name="offer_accepted1" value="True"> A</button>
<button class="btn btn-primary btn-large"
onclick="myFunction(this)" name="offer_accepted1" value="False">B</button>
</p>
<input type="text" name="timestamp1" id="timestamp1" value="0" />
{{ form.timestamp1.errors }}
<input type="text" id="c1" name="c1" value="0" />
{{ form.c1.errors }}

Logic on total sum of input values

I have created 4 input boxes with plus and minus to increase and decrease the value. I want to make a logic that as soon as the sum of all 4 values adds up to 5, it should disable the plus buttons and do not allow the user to add more.
This is the HTML:
<div id="field1">field 1
<button type="button" id="sub" class="sub">-</button>
<input type="text" id="1" value="0" class="field" />
<button type="button" id="add" class="add">+</button>
</div>
<div id="field2">field 2
<button type="button" id="sub2" class="sub">-</button>
<input type="text" id="2" value="0" class="field" />
<button type="button" id="add2" class="add">+</button>
</div>
<div id="field2">field 3
<button type="button" id="sub3" class="sub">-</button>
<input type="text" id="3" value="0" class="field" />
<button type="button" id="add3" class="add">+</button>
</div>
<div id="field2">field 4
<button type="button" id="sub4" class="sub">-</button>
<input type="text" id="4" value="0" class="field" />
<button type="button" id="add4" class="add">+</button>
</div>
This is the jQuery I am using to increase/decrease the values:
$("input").prop('disabled', true);
$('.add').click(function () {
$(this).prev().val(+$(this).prev().val() + 1);
});
$('.sub').click(function () {
if ($(this).next().val() > 0) $(this).next().val(+$(this).next().val() - 1);
});
This should work
$('.add').click(function () {
var value1 = $('#field1').find('input').val();
var value2 = $('#field2').find('input').val();
var value3 = $('#field3').find('input').val();
var value4 = $('#field4').find('input').val();
if ( value1 + value2 + value3 + value4 >= 5){
$('.add').prop('disabled', true);
} else {
$(this).prev().val(+$(this).prev().val() + 1);
}
});

Cannot create multiple text box with different id using JavaScript and jQuery

I am unable create multiple text field dynamically using JavaScript and jQuery. My code is below:
<div class="col-md-3">
<div class="form-group">
<label for="ques">No of questions</label>
<input name="no_of_question" id="ques" class="form-control" placeholder="no of question" type="text">
</div>
</div>
<div class="row">
<div class="col-md-8">
<div class="form-group">
<label>Questions</label>
<input type="button" style="line-height:13px; margin-right:2px;" class="btn btn-success btn-sm" name="plus" id="plus" value="+" onClick="addQuestionField();">
<input type="button" style="line-height:13px; margin-right:2px;" class="btn btn-danger btn-sm" name="minus" id="minus" value="-" onClick="deleteQuestionField();">
</div>
<div class="text-left" id="intro-add" style="display:none">
<input type="button" name="" class="btn btn-sm btn-info" value="Add">
</div>
</div>
</div>
<div id="container">
<div class="form-group" style="margin-top:5px;display:block" id="introBox0" >
<div>
<input type="text" style="width: 77.5%;float:left; margin-bottom:5px; margin-right:5px;" class="form-control inptbox0" id="scaleans00" name="labelname" placeholder="Answer" value="">
<input type="button" style="line-height:13px; margin-right:2px; margin-top:5px; float:left;" class="btn btn-danger btn-sm" name="labelminus" id="labelminus" value="-">
<div class="text-left" id="intro-add" style="display:block">
<input type="button" name="" class="btn btn-sm btn-info" value="Add" onclick="addMore(0,0)">
</div>
</div>
</div>
<hr>
</div>
Here user will create multiple question section and each question section user has to create multiple field using add button and will delete using minus button . Each question field should unique id.Suppose in section one there are 3 input field then its ids should be like this scaleans00,scaleans01,scaleans02... and for section two these should be scaleans10,scaleans11,scaleans12... and so on.
Here is my JavaScript code:
<script>
function addQuestionField() {
var get = $("#ques").val();
for (var i = 1; i < get; i++) {
$('#container').append('<div class="form-group dyn" style="margin-top:5px;display:block" id="introBox'+i+'"><div><input type="text" style="width: 77.5%;float:left; margin-bottom:5px; margin-right:5px;" class="form-control inptbox'+i+'" id="scaleans'+i+'0" name="labelname" placeholder="Answer" value=""><input type="button" style="line-height:13px; margin-right:2px; margin-top:5px; float:left;" class="btn btn-danger btn-sm" name="labelminus" id="labelminus" value="-"><div class="text-left" id="intro-add" style="display:block"><input type="button" name="" class="btn btn-sm btn-info" value="Add" onclick="addMore('+i+',0)"></div></div></div><hr>');
}
}
function deleteQuestionField() {
var textareas = $('#container .dyn');
if (textareas.length !== 0) {
textareas.last().remove();
$('#ques').val(textareas.length - 1);
}
}
function addMore(parent,child){
var mainDiv='#introBox'+parent;
$(mainDiv).append('<div><input type="text" style="width: 77.5%;float:left; margin-bottom:5px; margin-right:5px;" class="form-control inptbox'+parent+'" id="scaleans" name="labelname" placeholder="Answer" value="">'+'<input type="button" style="line-height:13px; margin-right:2px; margin-top:5px; float:left;" class="btn btn-danger btn-sm" name="labelminus" id="labelminus" value="-"></div>');
repopulate(parent);
}
function repopulate(k){
var mainId='.inptbox'+k;
var j=0;
$(mainId).each(function(i, e) {
if(i==0){
$(this).attr('id', 'scaleans' + i+j);
$(this).next().attr('onClick', function(old, n) {
return 'removeThis(' + i + ','+j+')';
})
$(this).next().attr('id', function(old, n) {
return 'labelminus' + i+j;
});
}else{
$(this).attr('id', 'scaleans' + i+(j+1));
$(this).next().attr('onClick', function(old, n) {
return 'removeThis(' + i + ','+(j+1)+')';
})
$(this).next().attr('id', function(old, n) {
return 'labelminus' + i+(j+1);
});
}
})
}
function removeThis(r,t) {
$("#scaleans" + r+t).remove();
$("#labelminus" + r+t).remove();
repopulate();
}
</script>
Here I can not create as per my requirement. Here is my full code.
I will be explaining to you what is going on with the current code you have put in Plunker
function addQuestionField() {
var get = $("#ques").val();
for (var i = 1; i < get; i++) {
In Your method addQuestionFiled(), the value retrieved into get variable is not truthy, if you are not entering any value into the
number of questions
textfield. Hence the html will not get appended
Fill in the number of question as 2, and then click add it will keeping on appending the html to container div as the 'var get' will have the value 2 and 'var i' is less than 'var get'
