fnv1a_32 hash in javascript consistent w/ libhashkit

fnv1a_32.js

// J. Charter Chapman
// fnv1a_32 in javascript based on libhashkit
// this one actually outputs consistent with hashkit
// there are a couple of interesting implementations out there

// string to byte array [think char *]
function getBytes(s) {
   var buf = [];
   for (var i = 0; i < s.length; i++) {
      buf.push(s.charCodeAt(i));
   }
   return buf;
}

function fnv1a_32( str )
{
   bytes=getBytes(str);
   hash= 0x811c9dc5; //< See libhashkit's algorithms for this magic number

   for ( var x = 0; x < str.length; x++ )
   {
      hash = (hash ^ bytes[x]) ;
      // this is: hash *= FNV_32_PRIME; 16777619u again see libhashkit the 
      hash += (hash << 1) + (hash << 4) + (hash << 7) + (hash << 8) + (hash << 24);
   }
   return (hash >>> 0).toString(16); // >>> 0 forces unsigned 32bit int
