[thelist] passing a JS variable to another page? Can I?

Fun problem ... there might be a more eloquent way of doing it, but 
this seems to work:

if your location is /index.html?chocolate=good&foo=bar

you can say:

query_string = 
unescape(location.href.substring(location.href.indexOf('?') + 1, 
location.href.length));

query_variables = query_string.split('&')

foo = '';
chocolate = '';
for (var i=0; i < query_variables.length; i++) {
   name_value_pair = query_variables[i].split('=');
   if (name_value_pair[0] == 'foo') {
     foo = name_value_pair[1];
   }
   else if (name_value_pair[0] == 'chocolate') {
     chocolate = name_value_pair[1];
  }
}


alert('the value of chocolate is ' + chocolate + '\n and foo is ' + foo);
