Question

I am using a multiple file upload scenario based on blueimp (http://blueimp.github.com/jQuery-File-Upload) and Ruby on Rails GEM Carrierwave. The issue that I am having is that a user can navigate away from the webpage prior to the uploading of files finishes. I am trying to create a way that if the file is currently being uploaded and the user navigates away from the page prior to the uploading finishes then it should return a confirmation dialogue. Any thoughts on how to accomplish this?

Added to the end of the form that is handling the file uploading.

$(window).bind('beforeunload', function () {
    if ($('#fileupload').data('fileupload')._active) {
        return 'Leaving now would abort your upload. Are you sure?';
    }
});
