Question

I am using JQuery to calculate some totals figures and I have run into a problem.

Let’s say I have two sets of inputs, each with a unique name.

$('[name="quantity\\[\\]"]')
$('[name="price\\[\\]"]')

I want to cycle through each set of inputs at the same time so that I can check both for (!isNaN) and (length !== 0), and if the values are valid, I want to multiply them together and add to a running total.

I know I can cycle through one selector using each(), but how can I cycle through two at the same time? is there an elegant way to accomplish this goal?

Answer 1

var prices = $('[name="price\\[\\]"]');
$('[name="quantity\\[\\]"]').each(function(i){
  var quantity = this;
  var price    = prices[i];
  // Compare them here.
});
