javascript sum returning NaN error
i have a javascript shopping basket, in which the sum is returning a NaN error,almost every time. in the code i have
$('#add-to-basket select').selectbox();
$('#contents select').selectbox().change(function (e) {
var product = $(this).parents('.product');
var ppu = product.find('.ppu').val();
product.find('.price .wrapper .value').text($(this).val() * ppu);
var total = 0;
$('.product .price .value').each(function (index, value) {
total += new Number($(value));
});
var form = $(this).parents('form');
form.ajaxSubmit(function () {
});
$('#total .value').text(total);
});
i tried using parsefloatm but still开发者_JS百科 it dosn't work...
$(value)
gives you the jQuery-wrapped element, not the actual value.
You want $(value).val()
instead if the elements are form inputs, or $(value).text()
if not.
Also, instead of new Number(...)
you should just use Number(...)
, or even +...
:
$('.product .price .value').each(function (index, value) {
total += +$(value).val();
});
See this question for the difference between new Number
and Number
.
