hexEncode 和 hexDecode:
String.prototype.hexEncode = function(){
var hex, i;
var result = "";
for (i=0; i<this.length; i++) {
hex = this.charCodeAt(i).toString(16);
result += ("000"+hex).slice(-4);
}
return result
}
Back again:
String.prototype.hexDecode = function(){
var j;
var hexes = this.match(/.{1,4}/g) || [];
var back = "";
for(j = 0; j<hexes.length; j++) {
back += String.fromCharCode(parseInt(hexes[j], 16));
}
return back;
}
