btoa method

String btoa(String data)

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

You can use this method to encode data which may otherwise cause communication problems, transmit it, then use the Window.atob method to decode the data again. For example, you can encode control characters such as ASCII values 0 through 31.

Implementation

external String btoa(String data);
