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。
let character = 'A'; let asciiCode = character.charCodeAt(0); console.log(asciiCode); // 输出: 65 3. 手动转换 你也可以通过数学运算手动将数字转换为ASCII字符。 代码语言:txt 复制 function numToAscii(num) { if (num < 0 || num > 127) { throw new Error('Number must be in the range...

What Is an ASCII to UTF8 Converter? This tool easily converts ASCII bytes to UTF8 text. Where possible, it merges multiple ASCII characters into a single UTF8 character. This is accomplished by checking each ASCII character's binary representation. If it starts with a '0' then it's a ...
