Ban đầu, có NCSA Mosaic, và khảm tự gọi mình NCSA_Mosaic/2.0 (Windows 3.1), và khảm hiển thị hình ảnh cùng với văn bản, và có rất nhiều niềm vui.

15 năm sau ...

Sau đó, Google đã xây dựng Chrome và Chrome đã sử dụng Webkit và nó giống như Safari và muốn các trang được xây dựng cho Safari và do đó giả vờ là Safari. Và do đó, Chrome đã sử dụng WebKit và giả vờ là Safari và WebKit giả vờ là KHTML và KHTML giả vờ là Gecko và tất cả các trình duyệt giả vờ là Mozilla và Chrome gọi chính nó Mozilla/5.0 (Windows; U; Windows NT 5.1; en-US) AppleWebKit/525.13 (KHTML, like Gecko) Chrome/0.2.149.27 Safari/525.13và chuỗi tác nhân người dùng là một mớ hỗn độn và gần như vô dụng, và mọi người giả vờ là những người khác, và sự nhầm lẫn ngày càng nhiều.

Hãy nhớ rằng, đây là mã golf , vì vậy mã có ít byte nhất sẽ thắng.

Hãy thử trực tuyến! Giải thích: Opera có thể được xác định bởi (O)P(R/)nền tảng và IE bằng Tr(ident)công cụ của nó . Các trình duyệt khác bao gồm tên đầy đủ của họ trong tác nhân người dùng của họ, nhưng Edge đặt họ cuối cùng để nó phải được xử lý tách biệt với các trình duyệt khác. Chỉnh sửa: Đã lưu 1 byte bằng cách phát hiện Edge sau Trident và 1 byte bằng cách phát hiện Opera chỉ bằng Pcả hai nhờ vào @ThePirateBay.

Cách tiếp cận tương tự như câu trả lời Retina của Neil.

f=_=>_[x=`includes`]`P`?`Opera`:_[x]`Tr`?`IE`:_[x]`E`?`Edge`:_.match(/[CFS]\w+/)[0]

Những nỗ lực trước đây:

// With String.prototype.test, 83 bytes
f=_=>/P/.test(_)?`Opera`:/Tr/.test(_)?`IE`:/E/.test(_)?`Edge`:_.match(/[CFS]\w+/)[0]

// With array filtering, 113 bytes
f=_=>_[o=`Opera`,i=`includes`]`P`?o:[o,`Edge`,`Firefox`,`Chromium`,`Chrome`,`Safari`].filter(b=>_[i](b))[0]||`IE`

Thử nó:

const f=_=>_[x=`includes`]`P`?`Opera`:_[x]`Tr`?`IE`:_[x]`E`?`Edge`:_.match(/[CFS]\w+/)[0]
