I'm attempting to recreate this JSfiddle locally on my machine:
http://jsfiddle.net/jakecigar/LM8Gd/1/
I don't understand though because it will goto the menu screen like on the fiddle above, but the animations will not happen and the question will not cycle through. It will only stay on the length? question and stay there and none of the buttons will do anything.
I have 3 files: index.html, js.js, and styles.css.

It doesn't look like you've loaded jQuery into your page which js.js depends upon.
There should have been errors in the browser error console or debug console that point you in some useful direction. If you aren't looking there first when something doesn't work, that's one of the first things to learn.

I'm learning Javascript and forms in HTML and I knew about radio buttons. But the problem is when I'm coding 3 radio buttons for testing, somehow it doesn't work, and when I check "1" (it's a name) and I choose another one like "2", it doesn't uncheck "1"! Does my browser have a problem, or my code is wrong? I'm using the Microsoft Edge browser, and this is my code:
<form>
<label for="html">This one is Html </label>
<input type="radio" name="html" id="html" value="HTML">
<br>
<label for="css">This one is Css</label>
<input type="radio" name="css" id="css" value="CSS">
<br>
<label for="javscript">This one is Javascript</label>
<input type="radio" name="javscript" id="javascript" value="JAVASCRIPT">
</form>
Anyone know what is my problem?
name property is as a group. so if you set the same name on radio buttons, they are being in same group.
<form>
<label for="html">This one is Html </label>
<input type="radio" name="group1" id="html" value="HTML">
<br>
<label for="css">This one is Css</label>
<input type="radio" name="group1" id="css" value="CSS">
<br>
<label for="javscript">This one is Javascript</label>
<input type="radio" name="group1" id="javascript" value="JAVASCRIPT">
</form>
This is simple, you just need to use the same name for each group, here i used codetype:
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<meta http-equiv="X-UA-Compatible" content="IE=edge">
<meta name="viewport" content="width=device-width, initial-scale=1.0">
<title>Document</title>
<link rel="stylesheet" href="style.css">
</head>
<body>
<form>
<label for="html">This one is Html </label>
<input type="radio" name="codetype" id="html" value="HTML">
<br>
<label for="css">This one is Css</label>
<input type="radio" name="codetype" id="css" value="CSS">
<br>
<label for="javscript">This one is Javascript</label>
<input type="radio" name="codetype" id="javascript" value="JAVASCRIPT">
</form>
</body>
</html>
Please you can use radio button that time all radio button name set same then you select at that time one radio button.
<form>
<label for="html">This one is Html </label>
<input type="radio" name="skill" id="html" value="HTML">
<br>
<label for="css">This one is Css</label>
<input type="radio" name="skill" id="css" value="CSS">
<br>
<label for="javscript">This one is Javascript</label>
<input type="radio" name="skill" id="javascript" value="JAVASCRIPT">
</form>
Just use the same name attribute value for each group.
<form>
<label for="html">This one is Html </label>
<input type="radio" name="radio_button" id="html" value="HTML">
<br>
<label for="css">This one is Css</label>
<input type="radio" name="radio_button" id="css" value="CSS">
<br>
<label for="javscript">This one is Javascript</label>
<input type="radio" name="radio_button" id="javascript" value="JAVASCRIPT">
</form>
I have radio buttons that has a same class.
and this radio buttons is dynamic, that's why I am thinking on using the class for validation.
Here is my code.
$('#listening_choices_wrapper').on('submit', function(e) {
e.preventDefault();
$(".validation_radio").each(function() {
});
});

</div>
<button type="submit" class="btn">Submit</button>

</html>
How can I validate them? so that the user can't submit it.
Any help would be really appreciated.
You can add the required attribute to all the input tags for native browser validation:
<div id="question_choices" class="listening_question_choice">
<input type="radio" class="validation_radio" name="answer_choice_0" value="17" required>
<label>Test 1</label>
<input type="radio" class="validation_radio" name="answer_choice_0" value="18" required>
<label>Test 2</label>
<input type="radio" class="validation_radio" name="answer_choice_0" value="19" required>
<label>Test 3</label>
<input type="radio" class="validation_radio" name="answer_choice_0" value="20" required>
<label>Test 4</label>
</div>
But to answer your question, I wrote this jQuery script:
$('#listening_choices_wrapper').on('submit', function(e) {
$('.error').remove()
e.preventDefault();
$('.listening_question_choice').each((i, e) => {
let valid = false
$(e).find('.validation_radio').each((i ,e) => {
if($(e).prop("checked")) {
valid = true
}
})
if (!valid) {
$(e).append('<div class="error" style="color: red;">Error: this radio is required!</div>')
}
})
});
I hope this helps!
I would suggest that you wrap each bank of answers in a fieldset element, and put the class on that. You can then iterate over those with each (as you did in your code) and look to see whether there are no input elements that are :checked
if($(this).find("input:checked").length == 0){
// no answer given
}
You can then also use some sort of label to improve the message to the user - and if any answers missed only then call e.preventDefault().
Live example below:
$('#listening_choices_wrapper').on('submit', function(e) {
var missingAnswers = [];
$(".validation_radio").each(function() {
if($(this).find("input:checked").length == 0){
missingAnswers.push($(this).data("label"));
}
});
if(missingAnswers.length > 0){
e.preventDefault();
alert(`You are missing answers to: ${missingAnswers}`)
}
});

I'm a newbie coder and cannot for the life of me figure out how to add up values for radio buttons below - any help would be greatly appreciated!
I am trying to create a diabetes screening assessment tool - where you will be able to assign different values to different risk factors.
You would need to use JavaScript to accomplish this.
Here's one way to do it:
Listen for the form's submit event
Prevent the default (so that the form doesn't get sent to the server)
Grab the value from each field. Fields use the name attribute from the HTML
Use parseInt on each field because they'll be strings
Add them up
Display the result (in this example, in the console)
const form = document.querySelector('form')
form.addEventListener('submit', event => {
event.preventDefault()
const total =
parseInt(form.age.value) +
parseInt(form.bmi.value) +
parseInt(form.famhistory.value) +
parseInt(form.diet.value)
console.log(total)
})

If you plan on adding values, here is a more flexible approach.
The idea is to loop through each relevant input (those that are inside your fieldset with ID controls), regardless of its name, so that if you add more checks, the same code will still work.
Create a score variable and increment it with the value of each input that is checked.
Be careful, you have the value 0 TWICE for the BMI check
window.addEventListener('DOMContentLoaded', function() {
var form = document.querySelector('form');
form.addEventListener('submit', function(event) {
event.preventDefault();
var inputs = document.querySelectorAll('#controls input');
var score = 0;
inputs.forEach(function(input) {
if (input.checked) {
score += parseInt(input.value, 10);
}
});
console.log(score);
});
});

i get my all question and option from text file by JSON and i succeeded it .
But my main problem is all my radio button is checked where i want to if one button is checked then other button is unchecked .
what my problem in code ? what i do? and why cause this problem ?
?** for style i use W3.CSS **?
Your HTML input radio should have the same name attribute, like this:
<input class="w3-radio" type="radio" name="Ch" value="a"> <label id="radio1"></label></input></br>
<input class="w3-radio" type="radio" name="Ch" value="b"><label id="radio2"></label> </input></br>
<input class="w3-radio" type="radio" name="Ch" value="c"> <label id="radio3"></label></input></br>
Your radio buttons should all use the same name :)
<input class="w3-radio" type="radio" name="Ch" value="a"> <label id="radio1"></label></input></br>
<input class="w3-radio" type="radio" name="Ch" value="b"><label id="radio2"></label> </input></br>
<input class="w3-radio" type="radio" name="Ch" value="c"> <label id="radio3"></label></input></br>
Name of your radio input fields should be same for specific question's options. Like below:
First group of radios
<input type="radio" name="rad" value="radopt1" id="radopt1"><label for="radopt1">Radio Option1</label></input>
<input type="radio" name="rad" value="radopt2" id="radopt2"><label for="radopt2">Radio Option2</label> </input>
<input type="radio" name="rad" value="radopt3" id="radopt3"><label for="radopt3">Radio Option3</label></input>
Second group of radios
<input type="radio" name="rad1" value="rad1opt1" id="rad1opt1"><label for="rad1opt1">Radio1 Option1</label></input>
<input type="radio" name="rad1" value="rad1opt2" id="rad1opt2"><label for="rad1opt2">Radio1 Option2</label> </input>
<input type="radio" name="rad1" value="rad1opt3" id="rad1opt3"><label for="rad1opt3">Radio1 Option3</label></input>
I just read all the other topics I could find with same problem I had but it didn't help me that's why I'm posting here.
I'm trying to have other form questions appear based on option value of 3rd question.
According to other topics with same function this should work just fine, but for me nothing happens when I change values and I couldn't find any errors. I'm still new at JS.
Thanks in advance. Cheers!

Your code, for the most part, works fine. The main mistake you made was that you are trying to execute code on elements that don't yet exist. You need to either a) run the code at the end of the document, or more commonly b) put the code in a document.ready handler.
jsFiddle example
$( document ).ready(function() {
//your code here
});
Note that in the example fiddle that I added $('.huddle_q, .jnj_q').hide(); to hide the elements first when you change the drop down.
