Topic awaiting preservation: Server decoding (Page 1 of 1)

Anyone see why this wont run on the server?
It does'nt seem to exist an array called 'digits'??
(ASP - using Jscript.)

var digits = new Array();



for (var i=0; i<26; i++)

{

  digits["A".charCodeAt(0)+i] = i;

  digits["a".charCodeAt(0)+i] = i+26;

}

for (var i=0; i<10; i++)

{

  digits["0".charCodeAt(0)+i] = i+52;

}



digits[0x2b] = 62;

digits[0x2f] = 63;



function setDecodeBase64(string)

{

  var val = "";

  val += (digits[string.substr(0,1).charCodeAt(0)] << 2);

  val += (digits[string.substr(1,1).charCodeAt(0)] >> 4);

  val += (digits[string.substr(1,1).charCodeAt(0)] & 0xf) << 12;

  val += ((digits[string.substr(2,1).charCodeAt(0)] >> 2) << 8);

  val += ((digits[string.substr(2,1).charCodeAt(0)] & 0x3) << 22);

  val += (digits[string.substr(3,1).charCodeAt(0)] << 16);

  return val;

}

amikael: First, to avoid the problems of seeing your code unindented and "polluted" by linkwords and other slimies, you should put it in the [ code ] UBB code.
Next, have you tried to introspect the digits array in the setDecodeBase64() function ? Does the code the function work if you put it at the same scope level as the initialization of the array ?
Finally, you can get rid of your substr() calls and simply access the right character in the string via the parameter of the charCodeAt() function

Cheers,
