The data-url
attribute of the input is read by the plugin when initializing. It is not automatically read afterwards. Have you tried updating the URL as follows?
var fu = $('#fileupload');
fu.fileupload('option', 'url', fu.data('url'));
Of course, this would be done after updating the data-url
attribute of the element using
fu.data('url', 'new-url-you-want-here');
and you could, I think, skip updating the attribute altogether and only change the option of the plugin.
fu.fileupload('option', 'url', 'new-url-you-want-here');
