Answer 1

Use map() function.

attribute_sets = $('.attribute_set :selected').map(function(i, selected){
    return {
       'id' : $(this).val(),
       'name' : $(this).text(),
    }
}).get();

try

$('.attribute_set :selected').each(function(i, selected){
  attribute_sets.push({
   id: $(selected).val(), // getting id 
   name: $(selected).text() // getting name
});
