Is there JSON encode/decode base64 encode/decode function in JavaScript?
775
Base64 is a safe encoding for JSON.
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).
In JavaScript there are two functions respectively for decoding and encoding Base64 strings: btoa() : creates a Base64-encoded ASCII string from a "string" of binary data ("btoa" should be read as "binary to ASCII"). atob() : decodes a Base64-encoded string ("atob" should be read as "ASCII to binary").
btoa(): accepts a string where each character represents an 8bit byte. If you pass a string containing characters that cannot be represented in 8 bits, it will probably break. Probably that's why btoa is deprecated.
Yes, btoa() and atob() work in some browsers:
var enc = btoa("this is some text"); alert(enc); alert(atob(enc)); JSON and base64 are completely independent.
Here's a JSON stringifier/parser (and direct GitHub link).
Here's a base64 Q&A. Here's another one.
