File Upload Progress Bar without using AJAX

Question

I have a standard multi-part form that uploads a file to a remote URL, which responds with redirect header.

Because the page loads from www.site-a.com & the form posts to www.site-b.com, I can't use the usual ajax.form submission process.

I have no access to configure the remote www.site-b.com server.

Is there a way to monitor the current upload progress directly from the browser with jQuery?

如果www.site-b.com网站是您的站点，则可以将Access-Control-Allow-Origin设置为*或site-a，然后使用ajax。
