I would like to know how to convert a normal Javascript string into an array of octets/characters. Like you would do with a classic C unsigned char array. I am using the Struct/JSPack library and need to extract/unpack some values from data coming in a string.
Thanks!
See String.charCodeAt .
var str = 'ABCDEFGHIJKLMNOPQRSTUVWXYZ0123456789';
var result = [];
for(var i = 0, length = str.length; i < length; i++) {
var code = str.charCodeAt(i);
// Since charCodeAt returns between 0~65536, simply save every character as 2-bytes
result.push(code & 0xff00, code & 0xff);
}
alert(result);
