Radio button calculator with nested if Stateme

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);
});

How to set checked radio button using name and attr in jquery?

I am working with some radio input and want to set them checked while edit function. I used ajax response. I have to set them checked.
The code sample is following:
<form>
Group 1:
<input type="radio" name="ans1" str="ans_a" value="1" />
<input type="radio" name="ans1" str="ans_b" value="2" />
<input type="radio" name="ans1" str="ans_c" value="3" />
<input type="radio" name="ans1" str="ans_d" value="4" />
Group 2:
<input type="radio" name="ans2" str="ans_a" value="1" />
<input type="radio" name="ans2" str="ans_b" value="2" />
<input type="radio" name="ans2" str="ans_c" value="3" />
<input type="radio" name="ans2" str="ans_d" value="4" />
Group 3:
<input type="radio" name="ans3" str="ans_a" value="1" />
<input type="radio" name="ans3" str="ans_b" value="2" />
<input type="radio" name="ans3" str="ans_c" value="3" />
<input type="radio" name="ans3" str="ans_d" value="4" />
</form>
I get from ajax response the following:
var ans_name = ans1,ans2,ans3;
var str = ans_c,ans_a,ans_d;
That means i have to set checked the 3rd radio input of gruop 1 and so on.
How can i set checked the corresponding radio button by jquery?

Select based on attribute equals selector and update the checked property.
var ans_name = 'ans1,ans2,ans3';
var str = 'ans_c,ans_a,ans_d';
// split the string into array by ,
var names = ans_name.split(','),
val = str.split(',');
// iterate over names array
names.forEach(function(v, i) {
// generate the selector and get jQuery object using that
$('[name="' + v + '"][str="' + val[i] + '"]')
// update the property
.prop('checked', true);
})
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
Group 1:
<input type="radio" name="ans1" str="ans_a" value="1" />
<input type="radio" name="ans1" str="ans_b" value="2" />
<input type="radio" name="ans1" str="ans_c" value="3" />
<input type="radio" name="ans1" str="ans_d" value="4" /> Group 2:
<input type="radio" name="ans2" str="ans_a" value="1" />
<input type="radio" name="ans2" str="ans_b" value="2" />
<input type="radio" name="ans2" str="ans_c" value="3" />
<input type="radio" name="ans2" str="ans_d" value="4" /> Group 3:
<input type="radio" name="ans3" str="ans_a" value="1" />
<input type="radio" name="ans3" str="ans_b" value="2" />
<input type="radio" name="ans3" str="ans_c" value="3" />
<input type="radio" name="ans3" str="ans_d" value="4" />
</form>
Or generate a single selector using Array#map and Array#join methods.
var ans_name = 'ans1,ans2,ans3';
var str = 'ans_c,ans_a,ans_d';
var names = ans_name.split(','),
val = str.split(',');
$(names.map(function(v, i) {
// geneate the selector
return '[name="' + v + '"][str="' + val[i] + '"]';
})
// join the selectors
.join(','))
// update the property
.prop('checked', true)
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form>
Group 1:
<input type="radio" name="ans1" str="ans_a" value="1" />
<input type="radio" name="ans1" str="ans_b" value="2" />
<input type="radio" name="ans1" str="ans_c" value="3" />
<input type="radio" name="ans1" str="ans_d" value="4" /> Group 2:
<input type="radio" name="ans2" str="ans_a" value="1" />
<input type="radio" name="ans2" str="ans_b" value="2" />
<input type="radio" name="ans2" str="ans_c" value="3" />
<input type="radio" name="ans2" str="ans_d" value="4" /> Group 3:
<input type="radio" name="ans3" str="ans_a" value="1" />
<input type="radio" name="ans3" str="ans_b" value="2" />
<input type="radio" name="ans3" str="ans_c" value="3" />
<input type="radio" name="ans3" str="ans_d" value="4" />
</form>

Explode names and value with data what you get from response and check through loop and you will get radio checked with the correct answer.
var ans_name = "ans1,ans2,ans3";
var str = "ans_c,ans_a,ans_d";
var checkbox_names = ans_name.split(",");
var values = str.split(",");
$(checkbox_names).each(function(index, value){
$("[name='"+value+"'][str='"+values[index]+"']").prop("checked",true);
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/1.9.1/jquery.min.js"></script>
<form>
Group 1:
<input type="radio" name="ans1" str="ans_a" value="1" />
<input type="radio" name="ans1" str="ans_b" value="2" />
<input type="radio" name="ans1" str="ans_c" value="3" />
<input type="radio" name="ans1" str="ans_d" value="4" />
Group 2:
<input type="radio" name="ans2" str="ans_a" value="1" />
<input type="radio" name="ans2" str="ans_b" value="2" />
<input type="radio" name="ans2" str="ans_c" value="3" />
<input type="radio" name="ans2" str="ans_d" value="4" />
Group 3:
<input type="radio" name="ans3" str="ans_a" value="1" />
<input type="radio" name="ans3" str="ans_b" value="2" />
<input type="radio" name="ans3" str="ans_c" value="3" />
<input type="radio" name="ans3" str="ans_d" value="4" />

PHP pass total value of radio button

How to count the total value of radio button within the same page and pass to another php file? The total will be count at this page and i can get the total from answer.php file.
<form action="answer.php" method="POST">
<input type="radio" name="q1" value="1" />Yes <br />
<input type="radio" name="q1" value="0" />No <br />
<input type="radio" name="q2" value="2" />Yes <br />
<input type="radio" name="q2" value="0" />No <br />
<input type="radio" name="q3" value="3" />Yes <br />
<input type="radio" name="q3" value="0" />No <br />
<input type="submit" value="submit" name="submit"/>
</form>

I suggest using an array to count your values.
<input type="radio" name="q[]" value="2" />
<input type="radio" name="q[]" value="3" />
<input type="radio" name="q[]" value="4" />
<input type="radio" name="q[]" value="5" />
This will result in $_POST['q'] being an array. You can now do:
echo "The total amount is ".array_sum($_POST['q']);

Using jQuery- it is easy, just iterate through the inputs and tally up the values. Note that I gave the form an Id so it can be targetted directly if you have other form. The total can be passed to your other page - either via AJAX or using a standard HTML form as a hidden field. Alternatively - since this is a form and you are already passing it to a PHP page - you could simply submit the form and tally up the $_POST variables on the other side.
$('#testForm input').on('change', function() {
var total=0;
$('input[type=radio]:checked', '#testForm').each(function(){
total += parseInt($(this).val());
})
alert(total)
});
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.1/jquery.min.js"></script>
<form id="testForm" action="answer.php" method="POST">
<input type="radio" name="q1" value="1" />Yes <br />
<input type="radio" name="q1" value="0" />No <br />
<input type="radio" name="q2" value="2" />Yes <br />
<input type="radio" name="q2" value="0" />No <br />
<input type="radio" name="q3" value="3" />Yes <br />
<input type="radio" name="q3" value="0" />No <br />
<input type="submit" value="submit" name="submit"/>
</form>
Commented version for the OP:
$('#testForm input').on('change', function() {//triggers the function on any change in the form
var total=0;//initialises the total at 0 so that each round ottallying up resets before the tally
$('input[type=radio]:checked', '#testForm').each(function(){//selects each input in the #testForm that is checked
total += parseInt($(this).val());//adds the value of each checked radio button to the tally
})
alert(total); //alerts the final tally after all iterations
});

You don't need jquery for this. Add a class to your radio buttons so we can query them without risking getting other elements in the page, something like "my-radio"
This javascript will get you the sum:
function getRadioButtonsSum(radioClass) {
var radioBtns = document.querySelectorAll(radioClass);
var count = 0;
var i;
for (i = 0; i < radioBtns.length; i += 1) {
if (radioBtns[i].checked) {
count += +radioBtns[i].value;
}
}
return count;
}
getRadioButtonsSum('.my-radio');

how do I select a parameter a Javascript selector?

Hi there (I'm a complete JS newbie so please no bullying)
I'm trying to pass formID inside my score variable but I don't think I'm getting my selector right, can anyone tell me what I'm doing wrong ?
Edit: Sorry everyone, I'm getting tired. My issue: I cannot properly select the value of my score var.
JS
function addScore(formId) {
var show_id = $('#show_id-'+formId).val();
var user_id = $('#user_id-'+formId).val();
var score = $('input[value="tvshowrating' + formID +'"]').val();
HTML
<form id="40">
<div class="your-score">
<div class="">Your Score</div> <div id="flash"></div>
<input class="hover-star" type="radio" name="tvshowrating40" value="1" title="1" />
<input class="hover-star" type="radio" name="tvshowrating40" value="2" title="2" />
<input class="hover-star" type="radio" name="tvshowrating40" value="3" title="3" />
<input class="hover-star" type="radio" name="tvshowrating40" value="4" title="4" />
<input class="hover-star" type="radio" name="tvshowrating40" value="5" title="5" />
<input class="hover-star" type="radio" name="tvshowrating40" value="6" title="6" />
<input class="hover-star" type="radio" name="tvshowrating40" value="7" title="7" />
<input class="hover-star" type="radio" name="tvshowrating40" value="8" title="8" />
<input class="hover-star" type="radio" name="tvshowrating40" value="9" title="9" />
<input class="hover-star" type="radio" name="tvshowrating40" value="10" title="10" />
<input type="hidden" id="show_id-40" value="40" />
<input type="hidden" id="user_id-40" value="2" />
<span id="hover-test" style="margin:0 0 0 20px;"></span>
<input id="submitscore" type="submit" value="Submit scores!" onclick="addScore(40);" />
</div>
</form>
</div>

You probably want the checked value:
$('input[name="tvshowrating' + formID +'"]:checked').val()

How can I know which radio button is selected via jQuery?

You're selecting <input>s by value.
You probably want input[name=....

JavaScript to create a global radio button for all subsequent radio buttons?

I have this set of labels and radio buttons that look like this:
Entertainment: <input type="radio" name="entertainment" id="entertainment" value="0" checked/>
<input type="radio" name="entertainment" id="entertainment" value="1" />
<input type="radio" name="entertainment" id="entertainment" value="2" /><br />
Radio: <input type="radio" name="radio" id="radio" value="0" checked/>
<input type="radio" name="radio" id="radio" value="1" />
<input type="radio" name="radio" id="radio" value="2" /><br />
Dancing: <input type="radio" name="dancing" id="dancing" value="0" checked/>
<input type="radio" name="dancing" id="dancing" value="1" />
<input type="radio" name="dancing" id="dancing" value="2" /><br />
Music: <input type="radio" name="music" id="music" value="0" checked/>
<input type="radio" name="music" id="music" value="1" />
<input type="radio" name="music" id="music" value="2" /><br />
Television: <input type="radio" name="tv" id="tv" value="0" checked/>
<input type="radio" name="tv" id="tv" value="1" />
<input type="radio" name="tv" id="tv" value="2" /><br />
Film: <input type="radio" name="film" id="film" value="0" checked/>
<input type="radio" name="film" id="film" value="1" />
<input type="radio" name="film" id="film" value="2" /><br />
Theatre: <input type="radio" name="theatre" id="theatre" value="0" checked/>
<input type="radio" name="theatre" id="theatre" value="1" />
<input type="radio" name="theatre" id="theatre" value="2" />
The idea is that the three 'Entertainment' radio buttons at the top control all the radio buttons below. A 'global switch', if you will, to save people time. Does anyone know the necessary JavaScript/jQuery to accomplish this? I can't find a correct example online.

$(':radio[name=entertainment]').change(function() {
$(this).nextAll(':radio[value="'+ this.value +'"]').prop('checked', true);
$(this).nextAll(':radio[value!="'+ this.value +'"]').prop('checked', false);
});
