Can't Add Up Radio Button Values with jQuery - javascript

I'm trying to add up all the values of the radio buttons selected on Submit button press. It sometimes changes the 0 to a 200, but it isn't adding correctly. I'm not quite sure what is going on with this one, since the total amount sometimes changes, but isn't accurate.
See https://jsfiddle.net/amgodv58/

Here's some simplified code. You should be checking to see if the radio buttons have been checked off.

Only going to show the JS here.
$( ".submit-button" ).click(function() {
event.preventDefault();
calculateTotal($(this).closest('table'));
});
function calculateTotal($tab) {
var sum = 0;
$tab.find('input:checked').each(function() {
sum += parseInt($(this).val()) || 0;
});
$(".total").html(sum.toFixed(2));
}
parseInt($(this).val()) || 0 is a fancy way of saving against NaN. NaN || 0 is 0 since NaN is a falsy value.

How to enable a button when radio button from all the sets are selected?

I am working on a test and bumped into a problem.
How do I make a .js script that only enables button when all fields are checked.

I have found this .js online, but I can't make it fit well as I have multiple pages of test questions with different input names.
function numberOfCheckboxesSelected() {
return document.querySelectorAll('input[type=checkbox][name="seatdata[]"]:checked').length;
}
function onChange() {
document.getElementById('enable-on-two').disabled = numberOfCheckboxesSelected() < 3;
}
document.getElementById('world').addEventListener('change', onChange, false);
There were some issues with your codebase.
document.getElementById('world').addEventListener('change', onChange, false);
Issue There is no node with that specified id.
Submit button has more than one id. That is not possible.
document.querySelectorAll('input[type=checkbox][name="seatdata[]"]:checked')
Your input type is radio so the above one wont work. Also the name attribute is wrong.
I have added those fixes.
function numberOfCheckboxesSelected() {
return document.querySelectorAll('input[type=radio]:checked').length;
}
function onChange() {
console.log(numberOfCheckboxesSelected());
document.getElementById('enable-on-two').disabled = numberOfCheckboxesSelected() < 3;
}
document.querySelectorAll('input[type=radio]').forEach(node => {
node.addEventListener('change', onChange, false);
});

The above solution needs a little correction as it enables the submit button on two inputs selection instead of all three.
Replace following:
document.getElementById('enable-on-two').disabled = numberOfCheckboxesSelected() < 2;
By this:
let totalInputs = document.querySelectorAll('input[type=radio]').length;
document.getElementById('enable-on-two').disabled = numberOfCheckboxesSelected() < totalInputs;

console.log($(this).attr("name"));
var name = $(this).attr("name");
console.log($('input[name="+ name +"]:checked').val());
});
});
so what im focusing is, i able to get individual attribute name when i click on of the radio button. from that attribute name, i want to get the value. but not work.
do i able to do that?.
please help
You almost have it, you can get the value like this:
var checkedvalue = $('input[name="'+ name +'"]:checked').val();
Working example:
$(function() {
$('.radioDeal').on('input', function(){
var name = $(this).attr("name");
var checkedvalue = $('input[name="'+ name +'"]:checked').val();
console.log(name+' = '+checkedvalue);
});

Since the change event triggers when state changes from not checked to checked it is therefore the ideal event to use as the this refers to the radio just checked:
$('.radioDeal').on('change', function() {
console.log( `${this.name} = ${this.value}` );
});

$('.radioDeal').on('change', function() {
console.log( `${this.name} = ${this.value}` );

JS .checked not working in for ... in loop - in IE11

I have the following function which works great in chrome, but in IE 11 doesn't.
It is designed to:
Take a questionGroup value determining which group of questions we want an average score for
Get a collections of the inputs on the page
Loop through them
If they are 'checked' then get the class name which determines the group the question is in
Count the number of questions in the group we're looking for
Get the total score for all questions in the group
Divide the total score by the number of questions to get the average score for the group
function getGroupScore(questionGroup) {
var inputs = document.getElementsByTagName("input");
var countOfQs = 0;
var totalGroupScore = 0;
for (var element in inputs) {
if (inputs[element].checked) {
var theQuestionsGroup = inputs[element].className;
if (theQuestionsGroup == questionGroup) {
var answer = parseInt(inputs[element].value)
totalGroupScore += answer;
countOfQs++;
}
}
}
var groupScore = totalGroupScore / countOfQs;
return groupScore;
}
In debugging, the loop seems to never get passed the following stage:
if (inputs[element].checked)
Even though there are input fields that are checked
example of the form I'm looping through:
<form action="">

for-in is not how you loop through an HTMLCollection. Use a simple for or one of the "array like" approaches in this answer (which also explains why for-in isn't the right choice here). I suspect the problem is that there are no enumerable properties in the HTMLCollection on the platform where you're seeing the problem.
So for instance:
for (var element = 0 ; element < inputs.length; ++elements) {
In modern environments, HTMLCollection (what you get back from getElementsByTagName) may have the non-standard extension making it iterable (ES2015+) and giving it a forEach. If not, you can easily add it:
if (typeof NodeList !== "undefined" &&
NodeList.prototype &&
!NodeList.prototype.forEach) {
// Yes, direct assignment is fine here, no need for `Object.defineProperty`
NodeList.prototype.forEach = Array.prototype.forEach;
}
if (typeof HTMLCollection !== "undefined" &&
HTMLCollection.prototype &&
!HTMLCollection.prototype.forEach) {
// Yes, direct assignment is fine here, no need for `Object.defineProperty`
HTMLCollection.prototype.forEach = Array.prototype.forEach;
}
That code does both HTMLCollection and NodeList (what you get from querySelectorAll). Then you can use:
inputs.forEach(function(input) {
if (input.checked) {
// ...
}
});

JavaScript comparison in if not working?

I have following code to check maximum values of cars. But Whenever I select 10 in the table I didn't get the max value as 10 corresponding to the car.It is working good for other values except 10.
I debugged with alert and then I found the control is not at all entering in if condition even when the index[k] > max?
function findTop() {
var cars = ["Hyundai", "Maruti Suzuki", "Honda", "Chevrolet", "Tata"];
var index = [cars.length];
for (var i = 0; i < cars.length; i++) {
var list = document.getElementsByName(cars[i]);
for (var j = 0; j < 10; j++) {
if (list[j].checked == true) {
index[i] = list[j].value;
}
}
}
var max = 0;
var maxIndex = 0;
var text = "";
for (var k = 0; k < index.length; k++) {
alert(index[k] + " " + max);
if (index[k] >= max) {
alert(index[k] + " " + max);
max = index[k];
alert("max" + max);
maxIndex = k;
}
}
for (var l = 0; l < 5; l++) {
if (max == index[l]) {
text = text + "&nbsp" + cars[l];
}
}
document.getElementById("output").innerHTML = text + "&nbsp&nbsp&nbsp" + max;

Sorry, I dont know how to add Jsfiddle link? Any suggestions what I am doing wrong?
Your values are all strings; "10" (the string) will never be greater than the string-compared values "9", etc.
You need to make sure your comparisons are numeric, which you can do like so:
if (+index[k] >= max) {
function findTop() {
var cars = ["Hyundai", "Maruti Suzuki", "Honda", "Chevrolet", "Tata"];
var index = [cars.length];
for (var i = 0; i < cars.length; i++) {
var list = document.getElementsByName(cars[i]);
for (var j = 0; j < 10; j++) {
if (list[j].checked == true) {
index[i] = list[j].value;
}
}
}
var max = 0;
var maxIndex = 0;
var text = "";
for (var k = 0; k < index.length; k++) {
console.log(index[k] + " " + max);
console.log(typeof index[k]);
if (+index[k] >= max) {
console.log(index[k] + " " + max);
max = index[k];
console.log("max " + max);
maxIndex = k;
}
}
for (var l = 0; l < 5; l++) {
if (max == index[l]) {
text = text + "&nbsp" + cars[l];
}
}
document.getElementById("output").innerHTML = text + "&nbsp&nbsp&nbsp" + max;
