My guess is that you could still do it if you globally set async to
false. Wouldn't recommend it though.

Yes, David is right. My example would not work. Sorry about that.
For other jQuery AJAX functions, there's an option to set 'async' to
false if you do want to let your script halt until the AJAX response
is received. I don't think there's an option for getJSON for that, so
you'll have to do everything you need to do inside your callback, or
switch to using the $.ajax() function.

You need to include what you want to do within the callback:
$(function(){
var youtubeurl;
$.getJSON('data.inc.json', function(j){
youtubeurl = j.video_url;
so = new SWFObject(j.video_url, "TEST", "498", "278", "9.0.28","#000000",
"true");
//etc...
});
//lines here don't wait for the ajax call to complete before executing.
alert(typeof youtubeurl); //should alert undefined
});
Yes, youtubeurl will be set, but only after you get the response back
from the server, which happens long after the lines after $.getJSON()
get executed.

that's not the problem unfortunately, cause my real script is
different.
The problem must be connected to the way $.getJSON parses the data....

The scope of your youtubeurl variable exists only within the callback
function of your getJSON(). Set the variable outside first.

so = new SWFObject(youtubeurl, "TEST", "498", "278", "9.0.28",

hello,
I have a file data.inc.json with the variable
{
'video_url':'http://www.youtube.com/v/idididid&hl=de&fs=1'
}
which I open from my javascript by
$.getJSON(" data.inc.json", function(j){ var youtubeurl = j
["video_url"]; });
The value of the variable youtubeurl looks correct (http://www.youtube.com/v/idididid&hl=de&fs=1),
but when I want to use the url for another request, nothing happens.
If I want to load the youtube video like this
so = new SWFObject(youtubeurl, "TEST", "498", "278", "9.0.28",
"#000000", "true");
nothing happens.
If I do
var testvar = "http://www.youtube.com/v/idididid&hl=de&fs=1";;
so = new SWFObject(testvar, "TEST", "498", "278", "9.0.28", "#000000",
"true");
the video is loaded and plays.
Do I have to format the j["video_url"]?
all the best
Josp
