sample.js

var tagAttribute = 'data-tag-for-query';

$(elements).each(function() {
  $(this).attr(tagAttribute, 'true');
});

var nodes = document.querySelectorAll('[' + tagAttribute + '="true"]');

Array.prototype.forEach.call(nodes, function(node) {
  $(node).removeAttr(tagAttribute);
});

return nodes;
