That should alert the new value.. did you test your example? If it's not working, it could be possible that the alert() is firing before the AJAX call is complete. Off hand I can't remember if the script waits until the AJAX call completes before continuing, but I don't think it does.

the context is not the alert(it's just an example)
1 want to have mydata with the new value !
thank's

I'm puzzled about what you want... something like that?

var mydata="init_value";

$.post('http://myurl', {},function(result) {
mydata=result;
alert(mydata);
}, "json");

Whatever you want to be done when the data is available, you should put in the callback.
