[jQuery] getJSON url variable broken

[jQuery] getJSON url variable broken


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
