I'm new to jQuery and wanted to do a simple sum operation, however as I'm learning the syntax I still have difficulties.
I was able to generate the total value of the requests, however, I can not generate total value: the rate has the fixed value, so the value of the total is equal to the rate plus the value of the request. I have done simple summing algorithms using variables, however they return me NAN.
$(document).ready(function() {
$(".pizza-add-sub").append('<div class="plus qty-pizza">+</div><div class="mines qty-pizza">-</div>');
$(".qty-pizza").on("click", function() {
var $button = $(this);
var oldValue = $button.parent().find("input").val();
if ($button.text() == "+") {
var newVal = parseFloat(oldValue) + 1;
} else {
// Don't allow decrementing below zero
if (oldValue > 0) {
var newVal = parseFloat(oldValue) - 1;
} else {
newVal = 0;
}
}
$button.parent().find("input").val(newVal);
var valorTotal = 0;
var valoresMultiplicar = 0;
$(".qtdpedidos").each(function() {
valorTotal += parseFloat($(this).data("preco") * $(this).val());
})
$(".item span").each(function() {
valoresMultiplicar += parseFloat($(this).html());
})
$("#resultado").text((valorTotal));
});
});
