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.

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.
$(function(){
var youtubeurl;
$.getJSON('data.inc.json', function(j){
youtubeurl = j.video_url;
});
so = new SWFObject(youtubeurl, "TEST", "498", "278", "9.0.28",
"#000000", "true");
});

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
