"PHẦN MỘT. LỊCH SỬ THẾ GIỚI THỜI NGUYÊN THỦY, CỔ ĐẠI VÀ TRUNG ĐẠI" Không convert được chữ "thủy". Chữ "thủy" không convert được là do dấu hỏi nó là một ký tự riêng, nếu chạy loop bạn sẽ thấy "thủy" -> [t, h, u, "dấu hỏi", y]

1 cách khác ngắn gọn hơn với ES2015/ES6 String.Prototype.Normalize()

const str = "PHẦN MỘT. LỊCH SỬ THẾ GIỚI THỜI NGUYÊN THỦY, CỔ ĐẠI VÀ TRUNG ĐẠI"; const newStr = str.normalize("NFD").replace(/[\u0300-\u036f]/g, ""); console.log(newStr) >> PHAN MOT. LICH SU THE GIOI THOI NGUYEN THUY, CO ĐAI VA TRUNG ĐAI

@lazidoca: chữ Đ vẫn bị bạn ơi. Chuyển thành kiểu này thì xử luôn chữ Đ:

str .normalize("NFD") .replace(/[\u0300-\u036f]/g, "") .replace(/đ/g, "d") .replace(/Đ/g, "D");

Cảm ơn bạn, mình cần thêm dấu gạch nối nữa nên đã tìm được cái này: /* str = str.replace(/\W+/g, ' '); str = str.replace(/\s/g, '-'); */ Thêm 2 cái này ở cuối để chuyển khoảng trắng thành dấu gạch nối ví dụ: Viet Nam => Viet-Nam

Xin cảm ơn bạn, đúng thứ tôi dang cần. Nhưng tôi thấy bạn nên để phần xoá nhiều khoảng trắng sau phần xoá ký tự đặc biệt, bởi vì sau khi xoá ký tự đặc biệt đôi khi lại xuất hiện trường hợp 2 khoảng trắng liền kề. Xoá ký tự đặc biệt theo tôi nên dùng str = str.replace(/[^a-zA-Z0-9 ]/g, ""); thì đỡ phức tạp hơn.
