How do I execute some javascript after a file is downloaded?

Question

I have a page with a link to a file. When the link is clicked I use the code below to show a loading message:

$(\'#TerritoriesToExcelLink\').click(function()         


        

Answer 1

This is not possible to do with front end javascript, there is no way for it to retrieve the progress of a download and it doesn't have any events relating to downloads.

I don't think tracking the progress can be done with server side languages either.
