enable submit button only if radio button in all questions are selected jquery

i have a simple html form where i have like 50 questions, all the questions hasve ther own radio button options, something like below:
<h3 class="text-danger">1. Question 1</h3>
<input class="form-check-input" value="1" type="radio" name="q1" id="flexRadioDefault1">
<label class="form-check-label" for="flexRadioDefault1">
Option 1
</label>
<input class="form-check-input" type="radio" value="2" name="q1" id="flexRadioDefault1">
<label class="form-check-label" for="flexRadioDefault1">
Option 2 </label>
<h3 class="text-danger">2. Question 2</h3>
<input class="form-check-input" value="1" type="radio" name="q1" id="flexRadioDefault1">
<label class="form-check-label" for="flexRadioDefault1">
Option 1
</label>
<input class="form-check-input" type="radio" value="2" name="q1" id="flexRadioDefault1">
<label class="form-check-label" for="flexRadioDefault1">
Option 2 </label>
i want the user to complete all the questions,and only submit after completion, i did something like below:
$(function(){
$("input[type='radio']").change(function(){
$("input[type='submit']").prop("disabled", false);
});
});
<input type="submit" disabled="disabled"/>
however this is not accurate as the submit button enables if a user complete 1 question, can anyone please tell me how to accomplish this, thanks in advance

Make it simple by making one of the radio buttons selected
your code will look like
<h3 class="text-danger">1. Question 1</h3>
<input class="form-check-input" value="1" type="radio" name="q1" id="flexRadioDefault11" checked>
<label class="form-check-label" for="flexRadioDefault11">Option 1</label>
<input class="form-check-input" type="radio" value="2" name="q1" id="flexRadioDefaultq12">
<label class="form-check-label" for="flexRadioDefaultq12">Option 2 </label>
<h3 class="text-danger">2. Question 2</h3>
<input class="form-check-input" value="1" type="radio" name="q2" id="flexRadioDefaultq21" checked>
<label class="form-check-label" for="flexRadioDefaultq21"> Option 1 </label>
<input class="form-check-input" type="radio" value="2" name="q2" id="flexRadioDefaultq22">
<label class="form-check-label" for="flexRadioDefaultq22"> Option 2 </label>

$("#btn").on("click", function (e) {
e.preventDefault;
$(".radio").each(function (index) {
if (!$(this).is(":checked")) {
alert(index + "is uncheck");
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<input type="radio" class="radio" />
<input type="radio" class="radio" />
<input type="radio" class="radio" />
<input type="radio" class="radio" />
<input type="radio" class="radio" />
<button id="btn">submit</button>
You need tu ose .each() method.

Each radio question should have a unique name so I changed them to q1,q2,q3. Even I added a wrapper for each question block. Whenever a question is answered, I loop each question block and check whether any block still remains unanswered. If any block(question) is unanswered, doEnable variable changes to false and loop break out.
$(function(){
$("input[type='radio']").change(function(){
let doEnable = true;
$(".form-check-input-wrap").each(function(){
if($(this).find("input[type='radio']:checked").length == 0){
doEnable = false;
return false;
}
});
if(doEnable) {
$("input[type='submit']").prop("disabled", false);
}
});
});
<script src="https://cdnjs.cloudflare.com/ajax/libs/jquery/3.3.1/jquery.min.js"></script>
<h3 class="text-danger">1. Question 1</h3>
<div class="form-check-input-wrap">

Send radio button value using Ajax Script in

I am trying to send the radio button value to Controller via ajax request, and so far nothing works
<input class="form-check-input" type="radio" class="gender" name="gender" id="Female" value="Female">
<label class="form-check-label" for="Female">Female</label><br>
<input class="form-check-input" type="radio" class="gender" name="gender" id="Male" value="Male">
<label class="form-check-label" for="Male"> Male </label><br>
<input class="form-check-input " type="radio" class="gender" name="gender" id="Other" value="Other">
<label class="form-check-label" for="Other">Other</label><br>
I tried with the following methods that do not work for me:
$('.gender:checked').val();
$('input[name="gender"]:selected').val();
$('#gender').val();
Any help?

You should be responding to an event for example a click or an onchange event see more here:
<input class="form-check-input" type="radio" class="gender" name="gender" id="Female" value="Female" />
<label class="form-check-label" for="Female">Female</label><br>
<input class="form-check-input" type="radio" class="gender" name="gender" id="Male" value="Male" />
<label class="form-check-label" for="Male"> Male </label><br>
<input class="form-check-input " type="radio" class="gender" name="gender" id="Other" value="Other" />
<label class="form-check-label" for="Other">Other</label><br>
$("input[type='radio']").click((ev) => {
console.log("click",ev.currentTarget.attributes.value.value);
})
$("input[type='radio']").change((ev) => {
console.log("change",ev.target.attributes.value.value);
})
jsfiddle

In order to identidy the value of each field, use #id instead of .ClassName,
$('#Female:checked').val();
$('#Male').val();
$('#Other').val();
otherwise, you can use radio buttons

Maybe you need to use classes to your radios. For example:
<input type="radio" class="checkthis group_01" id="group_01_item_01">
<input type="radio" class="checkthis group_01" id="group_01_item_02">
<input type="radio" class="checkthis group_01" id="group_01_item_03">
<input type="radio" class="checkthis group_01" id="group_01_item_04">
<input type="radio" class="checkthis group_02" id="group_02_item_01">
// ...and so on
After this you can select all radios with .checkthis class, and a group by .group_01 class, and an item with id.
Now you can use jQuery to find a selected from a group, like this:
var object_array = $('.group_01').find(':checked');
if (object_array.length > 0) {
// you have a selected element
} else {
// there isn't selected element
}
UPDATED:
Without jQuery, only native JavaScript:
var object_array = document.body.querySelector('.group_01:checked');
The if statement is the same.

You can try something like
Just modify your function something like below
function validateForm() {
var totalQue = document.getElementsByClassName("surveyQuestions").length;
var selectedAns = document.querySelectorAll("input[type='radio']:checked").length;
if(totalQue != selectedAns){
alert("Must Check Option !!");
return false;
}
}
This will give you all radio buttons which are selected.

Do mutiple checked across various radio buttons in Javascript

I'm developing an application that display 2 graphs and contain radio buttons to change the time interval.
What i'm trying to do is, for example, if i select monthly in the 2nd set of radio buttons the first set should also have that option check.
<div class="panel-radio-buttons">
<form id="SettingMixRadioButtonsGroup1">
<label class="radio-inline"><input type="radio" name="radio1" value="1" id="BtnEnrollmentsInpatient"
ng-model="togglePefsBifsTimeFrame" ng-change='SetDay()'>Daily</label>
<label class="radio-inline"><input type="radio" name="radio1" value="2" id="BtnEnrollmentsInpatient2"
ng-model="togglePefsBifsTimeFrame" ng-change='SetWeek()' >Weekly</label>
<label class="radio-inline"><input type="radio" name="radio1" value="3" id="BtnEnrollmentsInpatient3"
ng-model="togglePefsBifsTimeFrame" ng-change='SetMonth()'>Monthly</label>
</form>
</div>
<div class="panel-radio-buttons">
<form id="SettingMixRadioButtonsGroup2">
<label class="radio-inline"><input type="radio" name="radio1" value="1" id="BtnEnrollmentsInpatient4"
ng-model="togglePefsBifsTimeFrame" ng-change='SetDay()'>Daily</label>
<label class="radio-inline"><input type="radio" name="radio1" value="2" id="BtnEnrollmentsInpatient5"
ng-model="togglePefsBifsTimeFrame" ng-change='SetWeek()' ng-checked="togglePefsBifsTimeFrame2" >Weekly</label>
<label class="radio-inline"><input type="radio" name="radio1" value="3" id="BtnEnrollmentsInpatient6"
ng-model="togglePefsBifsTimeFrame" ng-change='SetMonth()'>Monthly</label>
</form>
</div>
I've tried to checked using the following code in JS:
$scope.SetDay= function(){
document.getElementById("SettingMixRadioButtonsGroup1").child[0].checked = true;
document.getElementById("SettingMixRadioButtonsGroup2").child[0].checked = true;
};
But It won't perform the check on the child element... if i use the parent it works fine but its not a very scalable solution

This creates a handler for the change event for the radio buttons. It selects all radio buttons under panel-radio-buttons which have the same value attribute and sets their checked property to that of the element which triggered the event.
$("input[type=radio][name=radio1]").change(function() {
var val = $(this).attr("value");
var radio = $(".panel-radio-buttons input[type=radio][name=radio1][value=" + val + "]");
radio.prop("checked", $(this).is(":checked"));
});

check all function with outputting labels into a div

i have a group of check boxes and i want to use a check all function but only for the corresponding checkboxes for example if i click checkAll1 it will only highlight checkItem 1 but also will still allow me to check other check boxes.
you will see from the snippet below the code i currently have, i want to also be able to put the checkAll label when it comes out to the #check div to be in a p tag so i can style it.
hope this all makes sense
Many thanks
$("input[type='checkbox']").change(function(){
$("#checked").empty();
$("input[type='checkbox']:checked").each(function(){
$("#checked").html($("#checked").html() + $(this).next().text() + " ");

You can use value to call checkbox, Do something like this..
var chk1 = $("input[type='checkbox'][value='1']");
var chk2 = $("input[type='checkbox'][value='2']");
var chk3 = $("input[type='checkbox'][value='3']");
var chk4 = $("input[type='checkbox'][value='4']");
var chk5 = $("input[type='checkbox'][value='5']");
var chk6 = $("input[type='checkbox'][value='6']");
chk1.on('change', function(){
chk2.prop('checked',this.checked);
});
chk3.on('change', function(){
chk4.prop('checked',this.checked);
});
chk5.on('change', function(){
chk6.prop('checked',this.checked);
});
$("input[type='checkbox']").change(function(){
$("#checked").empty();
$("input[type='checkbox']:checked").each(function(){
$("#checked").html($("#checked").html() + $(this).next().text() + "<p></p>");
});
});

I tweak your code a little, and what you mean by able to put the checkAll label when it comes out to the #check div which i did't get it, try this below code :
$("input[type='checkbox']").change(function() {
$("#checked").empty();
$("input[type='checkbox']:checked").each(function() {
$("#checked").html($("#checked").html() + $(this).next().text() + " ");
});
});
$(".checkAll").click(function() {
if ( $(this).is(':checked') )
$(this).siblings(':checkbox').prop('checked', true);
else
$(this).siblings(':checkbox').prop('checked', false);
});
<div>
<!-- add class="checkAll" for checkAll checkbox only -->
<input type="checkbox" id="checkAll1" class="checkAll">

Assign a same class for the same row check boxes
