Start http server when using jstree v3.3.11 with external html data

[pte1601]

Hello jstree users
I am trying to run jstree v3.3.11 with external html data (see attached file extract) and I am always getting the error: CORS request not http). Does this mean I need to start a development http server and load the external html data from there?
Thanks for your assistance

Using the file protocol only works in Firefox - for all other browsers - use a dev http server. Unfortunately, this is a browser thing - nothing I can do on the jsTree side.

Hi vacata,
thanks;
I found out I also could disable CORS policy in firefox with setting config variable security.fileuri.strict_origin_policy to false.
But using this 2nd solution the changed event does not load the data anymore

.on("changed.jstree", function (e, data) {
var i,
j,
r = [];
for (i = 0, j = data.selected.length; i < j; i++) {
r.push(data.instance.get_node(data.selected[i]).a_attr.href);
}
$("#event_result").load(r[0]);
});
What could be here the reason?
Thanks for your assistance
