We use this function to encode the data that we are preparing to send in an Ajax call.

UrlEncodeObj

// return object as URL encoded string
// I did not write this code, it was pasted from somewhere.
UrlEncodeObj = function (o) {
   var sdata = '';
   for (var k in o) {
      if (sdata) {
         sdata += '&';
      }
      sdata += k + '=' + escape(o[k]);
   }
   return sdata;
};
