在JavaScript中,ASCII码的转换可以通过内置的函数和方法来实现。ASCII码是一种字符编码标准,用于表示英文字符、数字和一些特殊符号。 基础概念 ASCII码:美国信息交换标准代码,每个字符对应一个从0到127的整数。 字符编码:将字符转换为计算机可以识别的二进制数的过程。
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...

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。
