demos

function encodeBase64(str = '') {
  // string 转成 base64
   return window.btoa(unescape(encodeURIComponent(str)));
}

function decodeBase64(str = '') {
   // base64  反转 string （逆序嵌套）
   return decodeURIComponent(escape(window.atob(str)));
}


const text = 'Vue3 script setup pass props';

const binary = encodeBase64(text);
console.log(`binary =`, binary);

const string = decodeBase64(binary);
console.log(`string =`, string);

btoa()

The btoa() method creates a Base64-encoded ASCII string from a binary string (i.e., a string in which each character in the string is treated as a byte of binary data).

atob()

The atob() function decodes a string of data which has been encoded using Base64 encoding. You can use the btoa() method to encode and transmit data which may otherwise cause communication problems, then transmit it and use the atob() method to decode the data again. For example, you can encode, transmit, and decode control characters such as ASCII values 0 through 31.
