Javascript Hex Decode and Encode Javascript Hex Decode and Encode

One day this script would be handy, very handy indeed :) anyway,, If you can't say something good say nothing at all. :D but When you think something good… SAY IT.

String.prototype.hexEncode=function(){
  var r='';
  var i=0;
  var h;
  while(i<this.length){
    h=this.charCodeAt(i++).toString(16);
    while(h.length<2){
      h=h;
    }
    r+=h;
  }
  return r;
};
String.prototype.hexDecode=function(){
  var r='';
  for(var i=0; i<this.length; i+=2){
    r+=unescape('%'+this.substr(i,2));
  }
  return r;
};

Example:

'Tya Ganteng :P'.hexEncode()

will return:

5479612047616e74656e67203a50

and

'5479612047616e74656e67203a50'.hexDecode()

will return:

Tya Ganteng :P
