Answer 1

var cookiesArray = new Array();
$('.cookie').each(function() { 
  var id = $(this).attr(id);
  if(id != undefined) {
    cookiesArray.push(id);

});

Answer 2

I think this should do what you're after:

var ids = $('.cookie').map(function(index) {
    // this callback function will be called once for each matching element
    return this.id; 
});

Documentation for map.

Answer 3

You can try:

var cookiesArray = [];

$('.cookie').each( function(i,e) {
    /* you can use e.id instead of $(e).attr('id') */
    cookiesArray.push($(e).attr('id'));
});
