javascript - 用Javascript解码UTF-8(Decode UTF-8 with Javascript)

Question

I have Javascript in an XHTML web page that is passing UTF-8 encoded strings.(我在传递UTF-8编码字符串的XHTML网页中有Javascript。)

It needs to continue to pass the UTF-8 version, as well as decode it.(它需要继续传递UTF-8版本，并对其进行解码。) How is it possible to decode a UTF-8 string for display?(如何解码UTF-8字符串以进行显示？) <script type="text/javascript"> // <![CDATA[ function updateUser(usernameSent){ var usernameReceived = usernameSent; // Current value: Gr????????e var usernameDecoded = usernameReceived; // Decode to: Gr??e var html2id = ''; html2id += 'Encoded: ' + usernameReceived + '<br />Decoded: ' + usernameDecoded; document.getElementById('userId').innerHTML = html2id; } // ]]> </script>   ask by Jarrett Mattson translate from so
