I'm developing a questionnaire in Laravel. The questions and their answers are printed throw a foreach. Now I need to retrieve the selected radio/answer for each question in order to insert each couple in an indexed array. The problem is that the name of the html tag radio is dynamic and not static so how can I retrieve the answer for each question?
In the code, {{$answer[0]}} is the id of the answer, while {{$answer[1]}} the text of the answer
#foreach ($question->answers as $answer)
<div class ="radio">
<label>
<input type="radio" name={{$question->id_question}} value= {{$answer[0]}}>
{{$answer[1]}}
</label>
</div>
#endif
#endforeach
Please have a look at this, if it's what you're looking for:
<div id="container">
<div class ="radio01">
<label for="question1">question1</label><input type="radio" name="question1" id="question1" value="answer1">
<label for="question1">question1</label><input type="radio" name="question1" id="question1" value="answer2">
<label for="question1">question1</label><input type="radio" name="question1" id="question1" value="answer3">
<label for="question1">question1</label><input type="radio" name="question1" id="question1" value="answer4">
<label for="question1">question1</label><input type="radio" name="question1" id="question1" value="answer5">
</div>
<div class ="radio02">
<label for="question2">question2</label><input type="radio" name="question2" id="question2" value="answer1">
<label for="question2">question2</label><input type="radio" name="question2" id="question2" value="answer2">
<label for="question2">question2</label><input type="radio" name="question2" id="question2" value="answer3">
<label for="question2">question2</label><input type="radio" name="question2" id="question2" value="answer4">
<label for="question2">question2</label><input type="radio" name="question2" id="question2" value="answer5">
</div>
....
<script>
var selectedAnswers = function () {
var answers = [];
$('input:radio').each(function () {
var $this = $(this),
name = $this.attr('name');
value = $this.attr('value');
if ($(this).prop('checked')) {
answers.push({"name":name, "value":value});
}
});
return answers;
};
$('#container').on('change', ':radio', function() { console.log(selectedAnswers()); });
</script>
Also your html is not "optimal" missing double quotes and correct hierarchy:
<label>
<input type="radio" name={{$question->id_question}} value= {{$answer[0]}}>
{{$answer[1]}}
</label>
Should be (like in my example above):
<input type="radio" name="{{$question->id_question}}" id="{{$question->id_question}}" value=" {{$answer[0]}}">
<label for="{{$question->id_question}}">{{$answer[1]}}</label>
Function given below to get values of all input radio.
function get_answers() {
var answers = {};
$.each($("input:radio"), function () {
answers[$(this).attr("name")] = $(this).val();
});
return answers;
}

I am trying to create a pricing calculator that takes all of the checked radio buttons and pushes them into an array where it is added in the end. However, I would like to have one of the radio buttons take the attribute of the first radio button and multiply it by its own value.
I tried nesting an if statement inside of another if statement but it will only seem to add the values of the first if statement and ignore the second.
$(".w-radio").change(function() {
var totalPrice = 0,
values = [];
$("input[type=radio]").each(function() {
if ($(this).is(":checked")) {
if ($(this).is('[name="catering"]')) {
var cateringFunc = (
$(this).val() * $('[name="gastronomy"]').attr("add-value")
).toString();
values.push($(this).val());
}
values.push($(this).val());
totalPrice += parseInt($(this).val());
}
});
$("#priceTotal span").text(totalPrice);
});

When the condition is true you should use cateringFunc instead of $(this).val() when pushing into the values array and adding to totalPrice.
I assume you only want to get the added value from the selected radio button, so I added :checked to the selector. Then you also need to provide a default value if none of the gastronomy buttons are checked.
You shouldn't make up new attributes like add-value. If you need custom attributes, use data-XXX. These can be accessed using the jQuery .data() method.
$(".w-radio").change(function() {
var totalPrice = 0,
values = [];
$("input[type=radio]:checked").each(function() {
if ($(this).is('[name="catering"]')) {
var cateringFunc = (
$(this).val() * ($('[name="gastronomy"]:checked').data("add-value") || 0)
);
values.push(cateringFunc.toString());
totalPrice += cateringFunc;
}
values.push($(this).val());
totalPrice += parseInt($(this).val());
});
$("#priceTotal span").text(totalPrice);
});

I am trying to create a really simple radio button quiz with javascript and an html form. When I try to take the form question values and put them into variables, they're not being taken. When I console.log q1 I just get undefined.
I've tried giving the radio buttons id's with getElementById, doesn't work. I've also tried document.forms['infoForm']['question1'].value;
function results() {
event.preventDefault();
var q1 = document.getElementsByName('question1').value;
var q2 = document.getElementsByName('question2').value;
var q3 = document.getElementsByName('question3').value;
var q4 = document.getElementsByName('question4').value;
console.log(q1);
}
<form name="infoForm" id="infoForm" onsubmit="return results();" method="post">
<fieldset>
<legend>Here's a Quiz!</legend>
<div class="question">
quiz question 1<br>
<input type="radio" name="question1" value="W">W<br>
<input type="radio" name="question1" value="R1">R<br>
<input type="radio" name="question1" value="W">W<br>
</div>
<div class="question">

<input type="radio" name="question2" value="R2">R<br>
<input type="radio" name="question2" value="W">W<br>

<div class="question">

<input type="radio" name="question3" value="R3">R<br>

<input type="radio" name="question4" value="R4">R<br>
</div>
<input type="submit" value="Submit">
</fieldset>
</form>
When using console.log() for the question variables I would like to see the value the user has actually chosen, instead of undefined.
.getElementsByName() returns an array of elements. However, using it, and grabbing the first item, will only give you the first item in the in the radio button set, and not the selected radio button.
Since you have name attributes, you can just use the path to get the element like this:
document.infoForm.question1.value
You can then do that for all 4 questions so it looks something like this:
function results() {
event.preventDefault();
var q1 = document.infoForm.question1.value;
var q2 = document.infoForm.question2.value;
var q3 = document.infoForm.question3.value;
var q4 = document.infoForm.question4.value;
console.log(q1, q2, q3, q4);
}
<form name="infoForm" id="infoForm" onsubmit="return results();" method="post">
<fieldset>
<legend>Here's a Quiz!</legend>
<div class="question">

There are some errors in your code.
The function getElementsByName() returns a NodeList, so you can't access the property value on it. Try to get the first index of it: getElementsByName()[0].value
The variable event is not defined. I guess that you're using the function results as an event listener. If so, the event is sent as a parameter and you need to define it:
function results(event) {
event.preventDefault();
var q1 = document.getElementsByName('question1')[0].value;
var q2 = document.getElementsByName('question2')[0].value;
var q3 = document.getElementsByName('question3')[0].value;
var q4 = document.getElementsByName('question4')[0].value;
console.log(q1);
}
I am creating a simple quiz and would like to know how to show one question at a time but only using JavaScript. I do not know jQuery. Essentially, I would like the first question to be shown automatically.
Here is an example of what my HTML looks like:
<div id="q0">
<li>
<h3>1. The color of the sky is... </h3>
<input type="radio" name="question0" value="A">Green<br>
<input type="radio" name="question0" value="B">Blue<br>
<input type="radio" name="question0" value="C">Red<br>
<input type="radio" name="question0" value="D">Purple<br>
</li>
</div>
<div id="q1" style="visibility:hidden">
<li>
<h3>2. Paper comes from... </h3>
<input type="radio" name="question1" value="A">Water<br>
<input type="radio" name="question1" value="B">Cement<br>
<input type="radio" name="question1" value="C">Trees<br>
<input type="radio" name="question1" value="D">The Sky<br>
</li>
</div>
<div id="q2" style="visibility:hidden">
<li>
<h3>3. How many hours in a day? </h3>
<input type="radio" name="question2" value="A">24<br>
<input type="radio" name="question2" value="B">22<br>
<input type="radio" name="question2" value="C">16<br>
<input type="radio" name="question2" value="D">48<br>
</li>
</div>
I currently don't have script for showing next div and hiding the previous one because I don't know how to even start.
I'm looking to have it put into this form...
function nextQ(){
// code
}
... and for it to be called by this button:
<button onclick="next()">Next Question</button>
I am really new to HTML and JavaScript and would appreciate any help.
Thanks.

Though I agree with #Bitwise on using jQuery instead on javascript alone to ensure cross-browser compatibility. But since you insist on using javascript, here's what you should do.
1) Ensure that your <li>'s are enclosed in a container tag first (say, <ul>) so you iterate only through desired list.
2) use display:none property instead of visibility:hidden. visibility:hidden simply hides an element, but it will still take up the same space as before. display:none hides an element, and it will not take up any space.
Here's the updated code.
HTML:
<ul id="listContainer">
<div id="q0">
<li style="display:list-item">
<h3>1. The color of the sky is... </h3>
<input type="radio" name="question0" value="A"/>Green<br/>
<input type="radio" name="question0" value="B"/>Blue<br/>
<input type="radio" name="question0" value="C"/>Red<br/>
<input type="radio" name="question0" value="D"/>Purple<br/>
</li>
</div>
<div id="q1" >
<li style="display:none">
<h3>2. Paper comes from... </h3>
<input type="radio" name="question1" value="A"/>Water<br/>
<input type="radio" name="question1" value="B"/>Cement<br/>
<input type="radio" name="question1" value="C"/>Trees<br/>
<input type="radio" name="question1" value="D"/>The Sky<br/>
</li>
</div>
<div id="q2" >
<li style="display:none">
<h3>3. How many hours in a day? </h3>
<input type="radio" name="question2" value="A"/>24<br/>
<input type="radio" name="question2" value="B"/>22<br/>
<input type="radio" name="question2" value="C"/>16<br/>
<input type="radio" name="question2" value="D"/>48<br/>
</li>
</div>
</ul>
<button id="next">next</button>
Javascript:
document.getElementById('next').addEventListener("click",function(){
var listContainer = document.getElementById("listContainer");
var listItem = listContainer.getElementsByTagName("li");
for (var i=0; i < listItem.length-1; i++)
{
if(listItem[i].style.display == "list-item")
{
listItem[i].style.display = "none";
listItem[i+1].style.display = "list-item";
break;
}
}
});
Here's the fiddle.
Cheers!
I would twist the code a little. Add question class to every div which acts as question i.e .question { display:none }. Add active class to first question (i.e. .active{display:block}, it shows the first question. Look for all divs with question class and add them to a variable, with every next button pressed,remove active class from current question add active class to next div with class question using classList.add and classList.remove of Javascript until last question is reached. Count keeps the current question's number.
I've done it in the codepen http://codepen.io/dwanirdesh/pen/EaQOPg
Or code directly from below:
<div id="q0" class="question active">
<li>
<h3>1. The color of the sky is... </h3>
<input type="radio" name="question0" value="A">Green<br>
<input type="radio" name="question0" value="B">Blue<br>
<input type="radio" name="question0" value="C">Red<br>
<input type="radio" name="question0" value="D">Purple<br>
</li>
</div>
<div id="q1" class="question" >
<li>
<h3>2. Paper comes from... </h3>
<input type="radio" name="question1" value="A">Water<br>
<input type="radio" name="question1" value="B">Cement<br>
<input type="radio" name="question1" value="C">Trees<br>
<input type="radio" name="question1" value="D">The Sky<br>
</li>
</div>
<div id="q2" class="question">
<li>
<h3>3. How many hours in a day? </h3>
<input type="radio" name="question2" value="A">24<br>
<input type="radio" name="question2" value="B">22<br>
<input type="radio" name="question2" value="C">16<br>
<input type="radio" name="question2" value="D">48<br>
</li>
</div>
<button onclick="next()">Next Question</button>
## CSS ##
.question{
display:none
}
.active{
display:block
}
## JAVASCRIPT ##
var questionNumber=0;
var questions=document.querySelectorAll('.question');
function next(){
questionNumber++;
if(questions.length>questionNumber)
{
document.querySelector('.active').classList.remove('active');
questions[questionNumber].classList.add('active');
}
}
Here is the java script function code. For this to work, you need to make sure that the div display property to be set as or in the html code. Also you need to name the id of the button to be "next" so that it can be hidden on reaching the last button.
function nextQ(){
var blockFound = 0;
var lastQuestion = 0;
var divs = document.getElementsByTagName("div");
for(var i = 0; i < divs.length; i++){
if ( blockFound == 1){

I am trying to retrieve the label associated with the radio button instead of the value using the following javascript but the variable "chosentime" is still "unassigned". I checked my code by throwing in a few alerts the alert(radios[i].innerhtml); throws unassigned
var radios = document.getElementsByName('submitted[lunchset][lunch]');
for (var i = 0, length = radios.length; i < length; i++) {
if (radios[i].checked) {
alert(i);
alert(radios[i].value);
alert(radios[i].innerhtml);
chosentime = radios[i].innerhtml;
}
}
window.alert(chosentime);
}
Would appreciate any help. Thanks in advance.
You have to access the corresponding label separately, since it resides in a separate tag. Because the labels' for attribute is equal to its option's id, you can get to the label easily:
for(var i=0; i<radios.length; i++) {
var selector = 'label[for=' + radios[i].id + ']';
var label = document.querySelector(selector);
var text = label.innerHTML;
// do stuff
}
Also check out this fiddle
Using modern Javascript and CSS this is easy now.
input.labels
Give your button an id, and then give the label a for='id' making sure it is the same id as the button.
Buttons can have multiple labels so it returns a NodeList, if you only have 1 label, just take the first item in the list.
radioButtonClicked.labels[0];
Docs here.
Here is an example of how you would setup the HTML:
<div class="controls">
<input type="radio" name="select" id="large" class="radioButtons" checked>
<input type="radio" name="select" id="medium" class="radioButtons">
<input type="radio" name="select" id="small" class="radioButtons">
<input type="radio" name="select" id="tiny" class="radioButtons">
<label for="large" class="option option-1 checked">
<span class="optionLabel">Large</span>
</label>
<label for="medium" class="option option-2">
<span class="optionLabel">Medium</span>
</label>
<label for="small" class="option option-3">
<span class="optionLabel">Small</span>
</label>
<label for="tiny" class="option option-4">
<span class="optionLabel">Tiny</span>
</label>
</div>
A radiobutton have no innerhtml. You need to target the label. If it's always directly after the radio-button, try something like radios[i].nextSibling.innerhtml.
