consatan / strtr.js
Created September 9, 2021 06:10
php strtr 函数的 js 实现，用于实现简单的自定义编码，如 自定义 base64 编码
// php strtr 函数的 js 实现 v.a. https://www.php.net/manual/en/function.strtr.php
// 只实现了 strtr(string $str, array $replace_pairs) 这种调用方法，且 replace_pairs 里只能是单个字符替换为单个字符
// 目的是为了做凯撒密码实现
String.prototype.strtr = function(dic) {
return this.toString().split('').map(char => dic[char] || char).join('');
}
// 调用
let str = '123321123';
