I have Javascript in an XHTML web page that is passing UTF-8 encoded strings. It needs to continue to pass the UTF-8 version, as well as decode it. How is it possible to decode a UTF-8 string for display?

<script type="text/javascript">
// <![CDATA[
function updateUser(usernameSent){
    var usernameReceived = usernameSent; // Current value: Größe
    var usernameDecoded = usernameReceived;  // Decode to: Größe
    var html2id = '';
    html2id += 'Encoded: ' + usernameReceived + '<br />Decoded: ' + usernameDecoded;
    document.getElementById('userId').innerHTML = html2id;
}
// ]]>
</script>

推荐答案

回答原始问题：这是你如何解码javascript中的utf-8：

To answer the original question: here is how you decode utf-8 in javascript:

具体来说，

function encode_utf8(s) {
  return unescape(encodeURIComponent(s));
}

function decode_utf8(s) {
  return decodeURIComponent(escape(s));
}

我刚才在我的代码中使用了它，它运行得很完美。

I just used this in my code, and it works perfectly.
