JS để tiện ích hoạt động

$.fn.reverseChildren = function() {
    return this.each(function() {
        var $this = $(this);
        $this.children().each(function() {
            $this.prepend(this);
        });
    });
};
function reverseCommentsOrder() {
    $(".comments-content ol").reverseChildren();
}
$(document).ready(function() {
    if (localStorage.getItem("commentsOrder") === "reversed") {
        reverseCommentsOrder();
    }
});
$(".sort-option").on("change", function() {
    reverseCommentsOrder();
    localStorage.setItem("commentsOrder", "reversed");
});
