[jQuery] Return value instead of callback?

[pluffsy]

Hi!

I want to get a value from jQuery.get() and I want the function (in
the example called getFromServer()) to wait until the server has
loaded the value (not the normal multithreaded way with a callback).
I've tried to use the callback to set a global and the script to wait
until the global is set, but I can't get it to work.

This is what I want:

serverValue = getFromServer("test.php");

if(serverValue == "foo")
{
 ...
}

Is this somehow possible?

Thanks a lot.
