Sort divs bases on element's data attribute

Answer 1

the following should work:

$('.container').sort(function (a, b) {
  return $(a).find('.terminal').data('price') - $(b).find('.terminal').data('price');
}).each(function (_, container) {
  $(container).parent().append(container);
});

though I recommend against doing this without a common parent. The $(container).parent().append(container); part could be problematic if there are other child nodes present.

alternatively you could do this:

$('.terminal').sort(function (a, b) {
  return $(a).data('price') - $(b).data('price');
}).map(function () {
  return $(this).closest('.container');
}).each(function (_, container) {
  $(container).parent().append(container);
});
