使用String.fromCharCode也可以实现,需要进行两次fromCharCode,没有fromPointCode方便。下面展示了utf-8的4字节转换为unicode(utf-16)的过程。 //高char10位[一个unicode字符] (2+6+2=10)unicode = ((utf8Bytes[pos] & 0x3)) << 8 |((utf8Bytes[pos+1] & 0x3f) << 2) |((utf8Bytes[pos+2] >...
// 将ASCII码转换为字符 let asciiCode = 65; // 'A'的ASCII码 let char = String.fromCharCode(asciiCode); console.log(char); // 输出: "A" // 将字符转换为ASCII码 let char2 = 'B'; let asciiCode2 = char2.charCodeAt(0); console.log(asciiCode2); // 输出: 66 ...
使用String.fromCodePoint() 方法可以将 Unicode 编码转换回字符,这有助于处理特殊字符。 代码语言:txt 复制 let code = 128512; // 笑脸表情的 Unicode 编码 let char = String.fromCodePoint(code); console.log(char); // 输出: 😀 总之,charCodeAt() 是一个强大的工具,可以帮助开发者处理字符串中的字...
通过code创建字符串 alert( String.fromCodePoint(90) ); // Z //还可以用 \u 后跟十六进制代码,通过这些代码添加 unicode 字符 // 在十六进制系统中 90 为 5a alert( '\u005a' ); // Z 1. 2. 3. 4. 5. 6. 3.str.localeCompare(str2) ...
function Hex2Ascii(string){ var hexArray = string.split(" "); // 拆分字符串为数组 var asciiArray = hexArray.map(function(hex) { var decimal = parseInt(hex, 16); // 将16进制数转换为10进制数 return String.fromCharCode(decimal); // 将10进制数转换为对应的ASCII字符 }); var result =...
