Did you see Andrew's explanation of the problem?
Here's a stripped down version of your code from a couple of messages ago,
with notes showing the order of execution:
function geocode()
{
// FIRST
new Request({
method: 'post',
url: DOMAIN_URL + 'sample.php?v=' + new Date().getTime(),
onSuccess: function(response){
// THIRD - AFTER THE DOWNLOAD
}).send(queryString);
// SECOND - BEFORE THE DOWNLOAD!!
}
Now is the problem more clear?
Asynchronous operations in JavaScript always use callback functions. In an
Ajax download like this, you must either use the data within the callback
function itself, or from another function that is *called from* the callback
function.
