Add javascript variable to javascript src?

Question

this may sound a bit noobish, but I\'m trying to retrieve the video information for a YouTube video (I saw in some tutorial) basically here\'s the code

Answer 1

Either document.write it or createElement()/appendChild()

var id = "asdf";
document.write('\x3Cscript type="text/javascript" src="foo.js?id=' + id + '">\x3C/script>');
