Getting data from select within each and selected option

Question

I am trying to get the data of the selected option based on if it has the attribute select. The problem is that when I use the prev function my code always returns the first option which is Position X(1, 2, ect). How can I get the data name of the selected option within my each loop for for example position 2 has Blue selected so I should be able to retrieve 0:finopt:1 or 0:finopt:5 from the position 6 which has the option Red selected from the data name of the option that has the selected attribute.

$(document).ready(function(){
  $('.cart-product-options .cart option').each(function(sk,sv){
      if($(this).attr('selected')){
        console.log($(this).prev().prev().data('name'));
        console.log(sv);
      }
  });
});

Answer 1

You have to go up to the select and get it's name attribute using .att() function (.data('whatever') is designed for data-whatever="value" attributes)...

$('.cart-product-options .cart option').each(function(sk,sv) {
    if($(this).attr('selected')){
        console.log($(this).closest('select').attr('name'));
        console.log(sv);
    }
});

But if you just need to select the options that has selected attribute, you can do it in one select (so you won't need to loop through all option elements)...

$('div.cart-product-options select.cart option[selected]').each(function(sk,sv) {
    console.log($(this).closest('select').attr('name'));
    console.log(sv);
});
