See following 3 different ways to do the same thing. When referring to
I'm aware of this, but there can be situations where script can not be
allowed to continue, before certain stuff has been done for sure.

Here's a great blog post from Doug Crockford, one of the gods of Javascript
on the subject:
Many people prefer to use it synchronously. When used this way, the
JavaScript engine is blocked until the interaction with the server is
complete. Because it blocks, the flow of control looks a lot like
Like Blair says, you need to use a callback.
I'd do something like this:
var seed_id;
var seed;
function createSeed(callback) {
$.post('login/login.php',{action:'createseed'}, function(data) {
results = data.split('|');
seed_id = results[0];
seed = results[1];
if (callback)
Thank you for quick answers. However, problem still exists. Latter
alert-function would still fail, because variables wouldn't be set yet at
that moment (I will need those variables later in another call to server).
Problem falls back to asyncronous loading. Isn't there an easy way to use
Synchronous loading is proposed for jQuery 1.1. But I'm sure callbacks would
be able to do what you need...
Couldn't you just do:
createSeed(restOfScript);
function restOfScript() {
...
}
Then the rest of the script would run after the ajax request has returned.

Ok, I'm choosing that path while waiting for jQuery 1.1. Works fine. It's not
so critical issue, but the resulting code looks.. well, silly.
