I have this site and I need to implement a sum with input[type=radio].

This is the Javascript code that makes the sums.

<script>
        function formatCurrency(num) { // função original - sem modificação
          num = num.toString().replace(/\$|\,/g, '');
          if (isNaN(num)) num = "0";
          cents = Math.floor((num * 100 + 0.5) % 100);
          num = Math.floor((num * 100 + 0.5) / 100).toString();
          if (cents < 10) cents = "0" + cents;
          for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)
            num = num.substring(0, num.length - (4 * i + 3)) + ',' + num.substring(num.length - (4 * i + 3));
          return ("" + num + "." + cents);
        }

        var form = document.forms[0];
        var inputs = form.querySelectorAll('input[type=radio]');
        // iterar todos os inputs
        for (var i = 0; i < inputs.length; i++) {
          // vincular função ao evento "change"
          inputs[i].addEventListener('change', function() {
            var soma = 0;
            for (var j = 0; j < inputs.length; j++) {
              if (inputs[j].checked) {
                // interpreta como float, usando parseFloat ao invés de eval
                soma += parseFloat(inputs[j].value);
              }
            }
            form.hiddentotal.value = soma; // atribui valor ao campo oculto
            form.total.value = formatCurrency(soma) // exibe valor formatado
          }, false);
        }
                        </script>

But nothing appears... it does not generate the result...

In this other link it works perfectly... should it be something in the code?

Link that works

That ain’t java, that’s right javascript. They are very different languages.

Modifications to be made

The form <form action="/teste.php" name="formulario" id="formulario" method="post">
Put values value="10.00" and no names value="Com moldura" in all the input type radio in the frameless place value="0"
In the script change to var form = document.getElementById('formulario');

Below an executable example

function formatCurrency(num) { // função original - sem modificação
   num = num.toString().replace(/\$|\,/g, '');
   if (isNaN(num)) num = "0";
	cents = Math.floor((num * 100 + 0.5) % 100);
	num = Math.floor((num * 100 + 0.5) / 100).toString();
	if (cents < 10) cents = "0" + cents;
	  for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)
	    num = num.substring(0, num.length - (4 * i + 3)) + ',' + num.substring(num.length - (4 * i + 3));
	    return ("" + num + "." + cents);
}
							
	var form = document.getElementById('formulario');
	var inputs = form.querySelectorAll('input[type=radio]');
	// iterar todos os inputs
	for (var i = 0; i < inputs.length; i++) {
	  // vincular função ao evento "change"
	  inputs[i].addEventListener('change', function() {
	    var soma = 0;
	    for (var j = 0; j < inputs.length; j++) {
		if (inputs[j].checked) {
		  // interpreta como float, usando parseFloat ao invés de eval
		  soma += parseFloat(inputs[j].value);
		}
	    }
	    form.hiddentotal.value = soma; // atribui valor ao campo oculto
	    form.total.value = formatCurrency(soma) // exibe valor formatado
          }, false);
        }

the problem of not working on this page is that Document.Forms[0]; return the first form of the page, in this case, the survey form. assign an id to the form you want to do the math, or put (since you have jquery):

var form = $(".page_content_offset form").first();

AMENDMENT: How jquery is loaded after this function (the <script src="/js/jquery-2.1.1.min.js"></script> is after), should put inside a doc ready to run only after loading everything. And since you have a form id, you can "search" for the id var form = $("#formulario");. That’s how it goes:

var form = document.forms[0];

<script>
        function formatCurrency(num) { // função original - sem modificação
          num = num.toString().replace(/\$|\,/g, '');
          if (isNaN(num)) num = "0";
          cents = Math.floor((num * 100 + 0.5) % 100);
          num = Math.floor((num * 100 + 0.5) / 100).toString();
          if (cents < 10) cents = "0" + cents;
          for (var i = 0; i < Math.floor((num.length - (1 + i)) / 3); i++)
            num = num.substring(0, num.length - (4 * i + 3)) + ',' + num.substring(num.length - (4 * i + 3));
          return ("" + num + "." + cents);
        }

    $( document ).ready( function () {
        var form = $("#formulario");
        var inputs = form.querySelectorAll('input[type=radio]');
        // iterar todos os inputs
        for (var i = 0; i < inputs.length; i++) {
          // vincular função ao evento "change"
          inputs[i].addEventListener('change', function() {
            var soma = 0;
            for (var j = 0; j < inputs.length; j++) {
              if (inputs[j].checked) {
                // interpreta como float, usando parseFloat ao invés de eval
                soma += parseFloat(inputs[j].value);
              }
            }
            form.hiddentotal.value = soma; // atribui valor ao campo oculto
            form.total.value = formatCurrency(soma) // exibe valor formatado
          }, false);
        }
  });
  </script>
