I have this site and need to implement a sum with input[type=radio] .
This page is where I make the sums
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?
