JavaScript 计算中文GBK编码长度

function getGBKLength(str) { let totalLength = 0; for (let i = 0; i < str.length; i++) { const charCode = str.charCodeAt(i); if (charCode <= 127) { totalLength += 1; } else { totalLength += 2; } } return totalLength; }

console.log(getGBKLength('中文')); // 4 console.log(getGBKLength('JavaScript')); // 10
