這篇文章將討論如何在 JavaScript 中將字符轉換為其 ASCII 碼。 例如,ACSII 代碼'A'是 65,'0'是 48,'a'是 97 等。 1.使用String.charCodeAt()功能 這charCodeAt()方法返回UTF-16指定索引處的代碼單元。這將返回 0 到 65535 之間的整數。前 128 個 Unicode 代碼點(0 到 127)與 ASCII 字符集匹配。

For ASCII strings that contain single-byte characters, each character is split into a sequence of 8 bits. For non-ASCII strings that contain multibyte characters, the conversion to a byte array requires a more complex encoding process, such as UTF-8, which can encode characters that require ...
However, due to the JavaScript specifications mentioned above, some character encodings may not be handled properly when converted directly to strings. If you prefer to use strings instead of numeric arrays, you can convert them to percent-encoded strings, such as '%82%A0', using Encoding....
