Hi Erwan,
The problem is that i is not defined when the function(xml, url)
{ Profil[i].loadXML(xml, url);} is called by Timeline.
(Different scope.)
In most cases, Javascript will maintain scope. Eg
function foo(a, b) {
function foo2 () {
// has access to a & b
}
}
But in this case, perhaps because i is only local to the block, not
the surrounding function, it isn't working for you.
Remember that the function will be called by the browser in a
different Javascript thread when the response comes back from the
server with your data file.
I suggest:
1) Trying making i a variable for the surrounding function:
var i;
for (i = 0; i < nb_file_xml; i++) {
var fichier = "Profil" + (i+1) + ".xml";
tl.loadXML(fichier, function(xml, url) { Profil[i].loadXML(xml,
url); });
}
2) The url is passed to the function. The function can parse it to see
which Profil it should be loading.
3) A fancier solution is to create a function, on the fly, that uses a
constant.
Eg
for (var i = 0; i < nb_file_xml; i++) {
var fichier = "Profil" + (i+1) + ".xml";
var myfunc = new Function(xml, url, "Profil[" + i + "].loadXML
(xml, url);");
// dynamic programming! Should only be used if absolutely
necessary
tl.loadXML(fichier, myfunc);
}
Google for Javascript scope for more.
Good luck,
Larry
