Full file upload callback

Question

I would like to track, exclusively on the client side, the progress of the file download, especially when downloading the file.

Is there a JavaScript API that allows me to define a callback when the file upload is complete?

Answer 1

No, this is not possible using pure javascript. There are some methods that include using cookies from the server and continuous polling from the client. Here I gave an example:
