use iframe-transport with jasny bootstrap-fileupload

frontend.js

// First, you need download iframe-transport from following address
// https://github.com/cmlenz/jquery-iframe-transport/raw/master/jquery.iframe-transport.js
// Then, add <script/> tag to your page

$.ajax({
    url: '<url to send file to>',
    files: $('select the input:file html tags'),
    iframe: true, // use iframe as ajaxTransport
    success: function (data) {
        // Here we got data(response from server)
        
        // Workaround: re-initialize the fileupload (enable ui to show another file again)
        $('.fileupload').fileupload('clear').removeData('fileupload').fileupload();
    }
});
